Xanax is a brand-name oral tablet prescribed for certain anxiety disorders. Xanax contains the active ingredient alprazolam and belongs to the benzodiazepine drug class.

The Food and Drug Administration (FDA) has approved Xanax to treat the following in adults:

Drug details

Here is key information about Xanax:

  • Drug form: oral tablet
  • Generic available? yes
  • Prescription required? yes
  • Controlled substance? yes*
  • Year of FDA approval: 1981

* For more information, see “Is Xanax a controlled substance?” in the “Xanax misuse and addiction” section.

Xanax vs. Xanax XR

Another form of Xanax is available. It’s called Xanax XR, and it’s FDA approved to treat only panic disorder.

Xanax tablets are immediate release, which means all the medication is released as soon as the tablet dissolves. Xanax XR tablets are extended release (XR). This means the drug is released slowly over time.

To treat panic disorder, you’ll likely take Xanax three times per day. Xanax XR works over about 24 hours, so you’ll likely take a dose once per day. Your doctor may prescribe Xanax XR if once-daily dosing is more convenient for you. They may also prescribe this form if your panic disorder symptoms come back or worsen between doses of immediate-release Xanax.

This article focuses just on Xanax. To learn more about Xanax XR, talk with your doctor.

Xanax can cause mild or serious side effects. The following lists contain some of the key side effects that may occur while taking Xanax. These lists do not include all possible side effects. To learn about other mild side effects, talk with your doctor or pharmacist, or view Xanax’s prescribing information.

For more information about the possible side effects of Xanax, talk with your doctor or pharmacist. They can give you tips on how to manage any side effects that may concern or bother you.

Note: The Food and Drug Administration (FDA) tracks side effects of drugs it has approved. If you would like to notify the FDA about a side effect you’ve had with Xanax, you can do so through MedWatch.

* Xanax has a boxed warning for this side effect. This is a serious warning from the FDA.

Allergic reaction

As with most drugs, some people can have an allergic reaction after taking Xanax. This side effect was not reported in clinical trials of this drug but has occurred since the drug was approved.

Symptoms of a mild allergic reaction can include:

A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include:

  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your tongue, mouth, or throat
  • difficulty breathing

Call your doctor right away if you have an allergic reaction to Xanax, as the reaction could become severe. Call 911 or your local emergency number if your symptoms feel life threatening or if you think you’re having a medical emergency.

The Xanax dosage your doctor prescribes will depend on several factors. These include:

  • the condition you’re taking Xanax to treat and its severity
  • your age
  • the form of Xanax you take*
  • your liver function
  • other medical conditions you may have
  • other medications you may take
  • side effects you may have with Xanax

Xanax doses are not determined by weight.

Typically, your doctor will start you on a low dosage. Then, they’ll adjust it over time to reach the amount that’s right for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

For more details on the dosage of Xanax, see this article.

* Xanax also comes in a form called Xanax XR. To learn more, see the “Xanax vs. Xanax XR” section near the beginning of the article.

Xanax form and strengths (0.25 mg, 0.5 mg, 1 mg, and 2 mg)

Xanax comes as an oral tablet that’s available in four strengths: 0.25 milligrams (mg), 0.5 mg, 1 mg, and 2 mg.

Xanax tablet colors: White, peach, or blue

The color and shape of Xanax tablets vary by strength:

  • 0.25 mg: white, oval
  • 0.5 mg: peach, oval
  • 1 mg: blue, oval
  • 2 mg: white, rectangle with rounded corners

Note that the color and shape of the corresponding alprazolam tablets may differ from those listed for Xanax. (Alprazolam is the generic version of Xanax.)

Xanax also comes as a long-acting form called Xanax XR (extended-release). Xanax XR tablets come in the following strengths, colors, and shapes:

  • 0.5 mg: white, pentagon
  • 1 mg: yellow, square
  • 2 mg: blue, round
  • 3 mg: green, triangle

To learn more about dosages of Xanax XR, talk with your doctor.

Dosage for generalized anxiety disorder

To treat generalized anxiety disorder (GAD) in adults, the typical starting dosage of Xanax is 0.25 mg to 0.5 mg, three times per day.

It’s possible that your doctor will adjust your dose every 3 to 4 days until you’re taking the dose that’s right for you. This depends on how you respond to the starting dosage.

The maximum recommended dosage for GAD is 4 mg per day, split into three doses.

Dosage for panic disorder

To treat panic disorder in adults, the recommended starting dosage of Xanax is 0.5 mg three times per day.

It’s possible that your doctor will adjust your dose every 3 to 4 days until you’re taking the dose that’s right for you. This depends on how you respond to the starting dosage. Your dose should be increased by no more than 1 mg per day.

The average dosage for panic disorder is 5 mg to 6 mg per day, split into three doses. However, some people may need up to 10 mg per day, split into three doses.

If you take more than 4 mg of Xanax per day for this condition, your doctor may eventually suggest lowering your dosage.

For some people taking higher doses of Xanax for a while, Xanax can still be as safe and effective at a lower dosage. After Xanax became available, a study found that the drug remained effective for treating panic disorder when lowering the dosage.

What if I miss a dose?

If you miss a dose of Xanax, take it as soon as you remember. But if it’s nearly time for your next dose, skip the missed dose and just take your next dose as scheduled. You should not take double or extra doses to make up for missing a dose. Doing so can cause serious side effects. (For more information about side effects, see the “Xanax side effects” section.)

To help make sure that you do not miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.

Will I need to take this drug long term?

Xanax is not meant to be a long-term treatment. Your doctor will typically prescribe it for as short a time as possible.

It’s unknown whether it’s safe or effective to take Xanax for longer than 4 months for GAD. And it’s unknown whether it’s safe or effective to take the drug for longer than 10 weeks for panic disorder.

When you and your doctor agree that you should stop taking Xanax, your doctor will reduce your dose slowly. This helps avoid withdrawal symptoms you may have if you suddenly stop treatment.*

* Xanax has a boxed warning about the risk of dependence and withdrawal. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more about this, see the “Xanax dependence and withdrawal” section.

Xanax is a brand-name drug that contains the active ingredient alprazolam. This active ingredient is also available as a generic medication. A generic drug contains the same active ingredient as its brand-name version.

Generic alprazolam comes as a tablet, extended-release tablet, orally disintegrating tablet, and oral liquid concentrate.

The generic is considered to be as safe and effective as the original drug. Generics tend to cost less than brand-name drugs.

If you’re interested in the generic form of Xanax, talk with your doctor. They can tell you whether it comes in forms and strengths that can be prescribed for your condition.

You may wonder how Xanax compares with other medications that are prescribed for similar purposes, such as Ativan.

Xanax and Ativan may be used to treat anxiety symptoms, although the drugs also have other uses that differ. Both drugs come in oral tablet form. (Ativan also comes as an injection, but this form is not used to treat anxiety symptoms.)

The active ingredient in Xanax is alprazolam, while the active ingredient in Ativan is lorazepam.

For more details about how Xanax compares with Ativan, see this article.

You may be curious about how Xanax compares with other medications that are prescribed for similar purposes, such as buspirone.

Xanax and buspirone may be used to treat generalized anxiety disorder. These drugs also have other uses that differ. Both come as oral tablets.

These medications contain different active ingredients. The active ingredient in Xanax is alprazolam, and the active ingredient in buspirone is buspirone.

For more details about how Xanax compares with buspirone, see this article.

Here are answers to some frequently asked questions about Xanax.

Would my doctor prescribe Xanax for depression, sleep problems, or other conditions?

Maybe. Xanax is approved to treat only generalized anxiety disorder and panic disorder. However, your doctor might sometimes prescribe Xanax off-label for certain other uses. Off-label drug use is when a drug is prescribed for a purpose other than what the Food and Drug Administration (FDA) has approved it for.

Off-label uses of Xanax include short-term treatment of temporary anxiety symptoms. For example, Xanax might be prescribed off-label for anxiety associated with:

Xanax may also sometimes be prescribed off-label for sleep problems. The medication works quickly, so it can help you fall asleep if you have difficulty doing so. However, doctors prescribe Xanax only in certain circumstances because your sleep problems may come back when you stop taking the drug.

If you have additional questions about an off-label use of Xanax, talk with your doctor.

Is Xanax a narcotic?

No, Xanax is not a narcotic. Xanax is a type of drug called a benzodiazepine.

Narcotics are opioids, which are drugs related to the opium poppy. Examples include strong prescription pain relievers, such as morphine (MS Contin) and oxycodone (OxyContin, Xtampza ER, others).

Xanax has a boxed warning about the risk of severe harm or death if taken with opioids. For details, see the “Xanax precautions” section.

Your doctor and pharmacist can help answer other questions you have.

Is it safe to take Xanax with Adderall?

Xanax is not known to interact with Adderall. However, taking these medications together may not be safe.

Adderall is a stimulant medication that’s prescribed for the treatment of attention deficit hyperactive disorder (ADHD). It contains two active ingredients: amphetamine and dextroamphetamine. Doctors may sometimes prescribe Xanax with Adderall for people with ADHD who also have anxiety. Taking these medications together for this purpose as prescribed by a doctor is not known to be harmful.

However, both Xanax and Adderall have a risk of misuse.* Misuse refers to taking a drug for a purpose or in a way that a doctor has not prescribed. If Xanax is misused with Adderall, this may increase the risk of serious outcomes. These may include serious side effects, overdose, and addiction. (For more information about side effects, see the “Xanax side effects” section.)

You should take Xanax with Adderall only if your doctor has prescribed them. They can tell you more.

* Xanax and Adderall have a boxed warning about the risk of misuse and addiction. A boxed warning is the most serious warning from the FDA. To learn more about this, see the “Xanax misuse and addiction” section.

Can I take a pain reliever such as Tylenol during Xanax treatment?

Yes, it’s typically safe to take a mild pain reliever, such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin), while you’re taking Xanax.

However, not all pain relievers are safe to take with Xanax. For example, pain relievers that contain opioids can cause severe side effects and, in rare cases, death if taken with Xanax.* Examples of opioids include codeine, hydrocodone (Hysingla ER), and oxycodone (OxyContin, Xtampza ER, others).

It’s important to note that some pain-relieving drugs contain acetaminophen in combination with an opioid. Examples include:

  • acetaminophen/oxycodone (Percocet, Oxycet)
  • acetaminophen/hydrocodone
  • acetaminophen/dihydrocodeine

You should not take pain relievers that contain an opioid with Xanax unless your doctor has approved it. If you need a pain reliever during Xanax treatment, ask your doctor or pharmacist to recommend a suitable medication.

* Xanax has a boxed warning about the risk of severe harm or death if taken with opioids. A boxed warning is the most serious warning from the FDA. For more details, see the “Xanax precautions” section.

What’s a half-life chart, and does Xanax have one?

A half-life chart can show you the amount of a dose that may still be in your system after a certain amount of time. Your doctor or pharmacist may be able to describe what a half-life chart for Xanax would look like.

The half-life of a drug is the length of time it takes for half a dose of the drug to be removed from your body. It typically takes between four and five half-lives for a drug to fully leave your system.

Xanax has a half-life of about 11 hours. This means it takes about 2.5 days for Xanax to be fully removed from your body. However, the exact amount of time you’ll have Xanax in your system depends on various factors. These include your age, liver function, and other medications you may take.

You can reach out to your doctor or pharmacist if you have additional questions.

Can stopping Xanax treatment cause a hangover-like feeling?

It might. Stopping Xanax treatment can sometimes cause withdrawal symptoms* as the effects of the medication wear off. This can cause symptoms similar to those you might have with an alcohol hangover. For example, you may have a headache, nausea, or vomiting. You may also feel anxious or irritable.

You’re more likely to have withdrawal symptoms after stopping Xanax treatment if you’ve been taking the drug for a long time or at a high dose. However, these symptoms can also affect anyone who stops taking Xanax.

To help lower your risk of withdrawal symptoms, your doctor will gradually reduce your dose when you stop taking Xanax. If you have hangover-like symptoms when stopping Xanax treatment, talk with your doctor. They can recommend ways to help ease the symptoms.

* Xanax has a boxed warning about the risk of dependence and withdrawal. A boxed warning is the most serious warning from the FDA. To read more about this, see “Xanax dependence and withdrawal.”

The Food and Drug Administration (FDA) approves prescription drugs such as Xanax to treat certain conditions. Xanax may also be used off-label for other conditions. Off-label drug use is when an FDA approved drug is prescribed for a purpose other than what it’s approved for.

Xanax for generalized anxiety disorder

Xanax is FDA approved for the short-term treatment of generalized anxiety disorder (GAD) in adults.

Generalized anxiety disorder explained

GAD is a mental health condition that can affect your daily life and impact your relationships with others.

It’s common to have anxiety about the stresses of everyday life. However, with GAD, you have ongoing anxiety about everyday life that’s excessive and out of proportion.

Symptoms of GAD may include:

  • excessive, uncontrollable, long-lasting worries or fears
  • intrusive thoughts or difficulty concentrating
  • difficulty sleeping
  • restlessness
  • fatigue
  • irritability
  • tense muscles
  • nausea
  • diarrhea
  • heart palpitations
  • sweating

Xanax is a benzodiazepine drug that has a calming and relaxing effect. Doctors usually prescribe it for short periods of time. It’s typically used to help ease the symptoms of anxiety while other treatments for GAD, such as antidepressants, are taking effect.

Effectiveness for generalized anxiety disorder

Xanax is an effective medication for relieving anxiety. To find out how the drug performed in clinical trials, see Xanax’s prescribing information.

Benzodiazepines such as Xanax are included in guidelines for managing GAD, but only for short-term treatment to help ease anxiety symptoms. The guidelines recommend other options for first-line treatment of GAD. (“First line” means the first treatment a doctor prescribes for a condition.)

You can learn more about your condition in our anxiety hub and mental health hub.

Xanax for panic disorder

Xanax is FDA approved to treat panic disorder, with or without agoraphobia, in adults.

Panic disorder explained

Panic disorder is a common mental health condition that can affect your daily life and impact your relationships with others. It’s a type of anxiety disorder.

With panic disorder, you have unexpected and recurrent panic attacks. A panic attack is an intense feeling of fear that comes on suddenly. It may cause symptoms such as:

  • shaking
  • dizziness
  • nausea
  • pounding heartbeat
  • chest pain
  • sweating
  • difficulty breathing
  • a choking sensation

With panic disorder, you become afraid of having more panic attacks. This can make you avoid situations or places you feel may trigger a panic attack, which can lead to agoraphobia.

Agoraphobia is an intense and irrational fear of situations where you think you might have difficulty leaving or getting help if you have a panic attack. For example, you may be afraid of being in a crowd or in open or enclosed spaces. You may also be afraid of using public transportation or leaving your home alone.

Xanax is a benzodiazepine drug that has a calming and relaxing effect. Doctors usually prescribe it for short periods of time. Xanax is typically used to help ease panic attacks while other treatments for panic disorder, such as antidepressants, take effect.

Effectiveness for panic disorder

Xanax is an effective medication for reducing the number of panic attacks you have. To find out how the drug performed in clinical trials, see Xanax’s prescribing information.

Benzodiazepines such as Xanax are included in guidelines for managing panic disorder, but only for short-term treatment to help ease symptoms. The guidelines recommend other options for first-line treatment of this condition.

You can learn more about your condition in the MNT anxiety hub and mental health hub.

Xanax and children

Xanax is not FDA approved for any use in children. It’s unknown whether Xanax is safe or effective in children.

Your doctor may prescribe Xanax with other drugs for generalized anxiety disorder or panic disorder.

Xanax is typically prescribed for short periods of time to relieve anxiety symptoms while other treatments, such as antidepressants, are taking effect. Antidepressants can take about 4 to 6 weeks to start working for anxiety disorders.

Examples of antidepressants that may be prescribed with Xanax include:

Xanax can interact with several other medications. It can also interact with certain supplements as well as certain foods.

Different interactions can cause different effects. For instance, some interactions can interfere with how well a drug works. Other interactions can increase side effects or make them more severe. Drug-condition interactions can also cause certain effects. For information about these interactions, see the “Xanax precautions” section.

Xanax and other medications

Here is a list of medications that can interact with Xanax. This list does not contain all drugs that may interact with Xanax.

Before taking Xanax, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also, tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions.

If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.

Types of drugs that can interact with Xanax include:

  • Opioids: Opioids are powerful drugs that are also known as opiates or narcotics. They include strong prescription pain relievers and certain illegal drugs. Taking Xanax with opioids can lead to severe harm and, in rare cases, death.* Due to these risks, doctors will typically not prescribe Xanax with opioids unless there are no other suitable treatment options. Examples of opioids include:
    • buprenorphine (BuTrans, Sublocade, Belbuca)
    • buprenorphine/naloxone (Suboxone, Zubsolv)
    • fentanyl (Duragesic, Fentora, others)
    • heroin†
    • hydrocodone (Hysingla ER)
    • methadone (Methadose)
    • morphine (MS Contin)
    • oxycodone (OxyContin, Xtampza ER, others)
    • oxycodone/acetaminophen (Endocet, Percocet)
    • tramadol (ConZip)
  • Strong CYP3A inhibitors: Taking Xanax with drugs that are strong cytochrome P450 3A (CYP3A) inhibitors can increase the risk of side effects from Xanax.‡ Due to this risk, doctors typically will not prescribe Xanax with strong CYP3A inhibitors, except ritonavir (Norvir). Examples of these drugs include:
    • clarithromycin
    • ketoconazole
    • itraconazole (Sporanox, Tolsura)
  • Weak or moderate CYP3A inhibitors: Taking Xanax with drugs that are weak or moderate CYP3A inhibitors can increase the risk of side effects from Xanax.‡ If you need to take Xanax with one of these medications, your doctor will likely prescribe a Xanax dosage that’s lower than usual. Examples of weak or moderate CYP3A inhibitors include:
    • cimetidine (Tagamet HB)
    • erythromycin (Eryc, Ery-Tab, others)
    • fluvoxamine (Luvox)
    • nefazodone
  • Strong CYP3A inducers: Taking Xanax with drugs that are CYP3A inducers can make Xanax less effective. Examples of these drugs include:
    • carbamazepine (Tegretol, Carbatrol, Equetro, others)
    • phenytoin (Dilantin)
  • Ritonavir: Ritonavir (Norvir) is a drug used to treat HIV. Ritonavir can affect the breakdown of Xanax in your body. Your doctor may adjust your Xanax dosage if you take the drug with ritonavir.
  • Digoxin: Digoxin (Lanoxin) is a heart medication. Taking Xanax with digoxin may cause digoxin to build up in your body. Your doctor may monitor your digoxin level and reduce your digoxin dosage if needed.
  • CNS depressants: Xanax is a type of drug called a central nervous system (CNS) depressant. Taking Xanax with other CNS depressants may cause excessive sleepiness and breathing problems. If you need to take Xanax with one of these drugs, your doctor will likely prescribe a Xanax dosage that’s lower than usual. Examples of CNS depressants include:

* Xanax has a boxed warning about this risk. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). To learn more about this interaction, see the “Xanax precautions” section.
† Heroin is illegal for personal use in the United States, and Medical News Today does not support taking illegal substances. However, we do support access to important health information. This interaction is mentioned to help you stay safe during Xanax treatment.
‡ For more information about side effects, see the “Xanax side effects” section.

Xanax and herbs and supplements

Here’s some information about herbs, supplements, and Xanax treatment. Be sure to talk with your doctor before taking any herbs or supplements with Xanax.

St. John’s wort

Taking Xanax with the herb St. John’s wort may lower the level of Xanax in your body. This could make Xanax less effective than usual.

St. John’s wort is often used to treat depression. If you’re taking this herb, talk with your doctor. They can advise you on the right treatments for you.

Cannabis

Cannabis is often known as marijuana or weed. Taking Xanax with cannabis could increase the risk of side effects from Xanax, especially sleepiness. Due to this interaction, doctors will typically advise that you do not take Xanax with cannabis.

For more information about side effects of Xanax, see the “Xanax side effects” section. To learn more about cannabis and the drug, talk with your doctor.

Xanax and foods

Consuming grapefruit or grapefruit juice while taking Xanax could increase your risk of side effects from Xanax. It’s best to avoid consuming grapefruit products while taking Xanax.

For more information about side effects of Xanax, see the “Xanax side effects” section. If you have questions about consuming other foods with Xanax, talk with your doctor.

If you drink alcohol, it’s best to avoid drinking it while taking Xanax. Alcohol and Xanax can reduce the activity of your central nervous system (CNS). So consuming alcohol with Xanax can lower the activity further.

The CNS refers to the brain and spinal cord. This system helps regulate breathing, actions, thinking, and more.

Drinking alcohol with Xanax can increase your risk of side effects such as:

  • drowsiness
  • dizziness or lightheadedness
  • problems with balance or coordination
  • difficulty concentrating
  • difficulty speaking clearly
  • memory loss
  • slowed reaction time
  • breathing problems
  • coma

Consuming alcohol during Xanax treatment can also increase your risk of an overdose from Xanax and, in rare cases, death. If you feel you need help avoiding alcohol while taking Xanax, talk with your doctor.

Xanax has a boxed warning for the risk of misuse and addiction. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). The warning alerts doctors and patients to side effects that may be dangerous.

About misuse and addiction

Misuse refers to taking a drug for a purpose or in a way that a doctor has not prescribed. People often misuse drugs to produce a pleasurable, calm, or high feeling. Misuse can lead to addiction, which is when you’re unable to stop taking a drug, even though it may be causing harm.

Symptoms of Xanax misuse or addiction may include:

  • taking Xanax more often or in higher doses than prescribed
  • craving Xanax
  • spending a lot of time trying to obtain Xanax
  • having health, personal, social, work, or relationship problems due to Xanax

About Xanax misuse and addiction

Xanax misuse and addiction can lead to serious side effects, including breathing problems, seizures, paranoia, and suicidal thoughts or actions. Xanax misuse and addiction can also lead to overdose and, in rare cases, death. This is particularly the case if Xanax is taken with alcohol, illegal drugs, or other medications (especially opioids*).

If you’ve had problems with drug or alcohol misuse or addiction in the past, you may have an increased risk of these problems with Xanax. Your doctor will assess your risk of misuse and addiction before determining whether Xanax is right for you.

You should take Xanax exactly as prescribed by your doctor. It’s important that you do not increase your dose or take more than prescribed unless you first talk with your doctor. Also, be sure to contact your doctor as soon as possible if you have any symptoms of misuse or addiction, or any concerns about them.

* Xanax has a boxed warning about the risk of severe harm or death if taken with opioids. To learn more, see the “Xanax precautions” section.

Is Xanax a controlled substance?

Yes, Xanax is classified as a Schedule IV controlled substance. This means the medication has an accepted medical use, but it also has a risk of misuse and dependence.*

With dependence, your body becomes reliant on a drug to function as usual. If you suddenly stop taking a drug that your body has become dependent on, you could experience side effects known as withdrawal symptoms.

There are special rules around prescribing and supplying Schedule IV controlled drugs. Your doctor or pharmacist can tell you more about this.

* Xanax has a boxed warning from the FDA for the risk of dependence and withdrawal. To learn more, see the “Xanax dependence and withdrawal” section.

Other drugs like Xanax are available that can treat your condition. Some may be a better fit for you than others. If you’re interested in finding an alternative to Xanax, talk with your doctor. They can tell you about other medications that may work well for you. This could include other benzodiazepines. (Xanax is a type of drug called a benzodiazepine.)

Note: Some of the drugs listed here are used off-label to treat these specific conditions. Off-label drug use is when a drug that’s approved by the Food and Drug Administration (FDA) is prescribed for a purpose other than what it’s approved for.

Alternatives for generalized anxiety disorder

Examples of other drugs that a doctor may prescribe for generalized anxiety disorder include:

Alternatives for panic disorder

Examples of other drugs that may be prescribed for panic disorder include:

  • other benzodiazepines such as:
    • clonazepam (Klonopin)
    • lorazepam (Ativan)
  • SSRI antidepressants such as:
  • SNRI antidepressants such as:
    • venlafaxine (Effexor XR)
  • tricyclic antidepressants such as:
    • amitriptyline
    • imipramine

You may wonder how Xanax compares with other medications that are prescribed for similar purposes, such as Valium.

Xanax and Valium may be used to treat anxiety disorders, although both drugs have other uses that differ. These drugs come as oral tablets.

The active ingredient in Xanax is alprazolam, while the active ingredient in Valium is diazepam.

For more details about how Xanax compares with Valium, see this article.

You may be curious about how Xanax compares with other drugs that are prescribed for similar purposes, such as clonazepam.

Xanax and clonazepam may be used to treat panic disorder, and these drugs have other uses that differ. Both come as oral tablets, but clonazepam also comes as an orally disintegrating tablet.

These medications contain different active ingredients. The active ingredient in Xanax is alprazolam, while the active ingredient in clonazepam is clonazepam. (Clonazepam is also available as the brand-name drug Klonopin.)

To learn more about how Xanax is similar to and different from clonazepam, you can refer to this article.

Note: Xanax is classified as a Schedule IV controlled substance because it has a risk of misuse and dependence. For more information, see “Is Xanax a controlled substance?” in the “Xanax misuse and addiction” section.

Symptoms of withdrawal

Suddenly “coming off” Xanax can cause serious or even life threatening withdrawal symptoms. These may include:

  • withdrawal seizure
  • hallucinations (seeing or hearing things that are not really there)
  • psychosis (loss of touch with reality)
  • mania (state of heightened energy)
  • suicidal thoughts or actions

Other withdrawal symptoms associated with suddenly stopping Xanax may include:

  • headache
  • anxiety
  • depression
  • irritability
  • problems with thinking, understanding, or memory
  • dizziness
  • fatigue
  • insomnia
  • nausea and vomiting
  • diarrhea
  • muscle twitching
  • tremor
  • tingling or burning sensations
  • hearing problems, such as increased sensitivity to noise or ringing in your ears

Certain withdrawal symptoms may sometimes last for several weeks or months.

You may have an increased risk of dependence and withdrawal if you take more than 4 milligrams (mg) of Xanax per day. You may also have an increased risk if you take Xanax for a long period of time. However, these problems are also possible with lower doses and after taking the drug for a short time.

Talking with your doctor

To help avoid withdrawal symptoms, do not stop taking Xanax unless you first talk with your doctor. You should not stop your treatment suddenly. When you and your doctor agree that you should stop taking Xanax, they’ll reduce your dose slowly over time. This can help prevent withdrawal symptoms.

If you have withdrawal symptoms after your doctor has reduced your dose or had you stop treatment with Xanax, talk with them. Your doctor may increase your dosage again and then reduce it more slowly. However, if you have serious withdrawal symptoms, contact your doctor right away. If your symptoms feel life threatening, call 911 or your local emergency number immediately.

Suicide prevention

If you know someone at immediate risk of self-harm, suicide, or hurting another person:

  • Ask the tough question: “Are you considering suicide?”
  • Listen to the person without judgment.
  • Call 911 or the local emergency number, or text TALK to 741741 to communicate with a trained crisis counselor.
  • Stay with the person until professional help arrives.
  • Try to remove any weapons, medications, or other potentially harmful objects if it’s safe to do so.

If you or someone you know is having thoughts of suicide, a prevention hotline can help. The 988 Suicide and Crisis Lifeline is available 24 hours a day at 988. During a crisis, people who are hard of hearing can use their preferred relay service or dial 711 then 988.

If you can become pregnant, are breastfeeding, or are using birth control, it’s important to consider whether Xanax is a safe choice for you.

You can refer to this article for more information. If you have additional questions, talk with your doctor.

You should take Xanax according to the instructions your doctor gives you.

Xanax comes as an oral tablet.

When to take

You’ll usually take Xanax three times per day. For example, you may take it in the morning, after lunch, and in the evening. If you have anxiety that prevents you from falling asleep at night, your doctor may recommend taking your last dose of Xanax before going to bed.

Try to stick to the same times each day. Taking the medication around the same times of day helps keep a steady level of the drug in your body. This helps Xanax work effectively.

To help make sure that you do not miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.

Accessible labels and containers

If your prescription label is hard to read, talk with your doctor or pharmacist. Some pharmacies offer labels that have large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy does not have these options, your doctor or pharmacist may be able to direct you to one that does.

If you have difficulty opening medication bottles, ask your pharmacist if they can put Xanax in an easy-open container. They may also be able to recommend tools that make it simpler to open lids.

Taking Xanax with food

You can take Xanax on an empty stomach or after eating. And you can take the medication with or without food.

Can Xanax be crushed, split, or chewed?

Xanax tablets are scored and can be split if your doctor or pharmacist advises this. However, Xanax is not meant to be crushed or chewed. The manufacturer does not provide information on taking Xanax this way. If you have difficulty swallowing Xanax, talk with your doctor or pharmacist.

As with all medications, the cost of Xanax can vary. The actual price you’ll pay depends on your insurance plan, your location, and the pharmacy you use.

Before approving coverage for Xanax, your insurance company may require you to get prior authorization. This means that your doctor and insurance company will need to communicate about your prescription before the insurance company will cover the drug. The insurance company will review the prior authorization request and decide whether the drug will be covered.

If you’re not sure whether you’ll need to get prior authorization for Xanax, contact your insurance company.

Generic version

Xanax is available in a generic form called alprazolam. A generic drug is an exact copy of the active ingredient in a brand-name medication. The generic is considered to be as safe and effective as the original drug. And generics tend to cost less than brand-name drugs. To find out how the cost of alprazolam compares to the cost of Xanax, see this article.

If your doctor has prescribed Xanax and you’re interested in taking alprazolam instead, talk with your doctor. They may have a preference for one version or the other. You’ll also need to check your insurance plan, as it may only cover one or the other.

When you get Xanax from the pharmacy, the pharmacist will add an expiration date to the label on the bottle. This date is typically 1 year from the date they dispensed the medication.

The expiration date helps guarantee that the medication is effective during this time. The current stance of the Food and Drug Administration (FDA) is to avoid taking expired medications. If you have unused medication that has passed the expiration date, ask your pharmacist how to correctly dispose of it.

Storage

How long a medication remains good can depend on many factors, including how and where you store the medication.

You should store Xanax tablets at room temperature in a tightly sealed container. Avoid storing this medication in areas where it could get damp or wet, such as bathrooms.

Disposal

If you no longer need to take Xanax and have leftover medication, it’s important to dispose of it safely. This helps prevent others, including children and pets, from taking the drug by accident. It also helps keep the drug from harming the environment.

This article provides several useful tips on medication disposal. You can also ask your pharmacist for information about how to dispose of your medication.

Xanax is prescribed for generalized anxiety disorder and panic disorder.

Xanax is a type of drug called a benzodiazepine. It eases anxiety by boosting the effect of GABA, a type of neurotransmitter in your brain. GABA is short for gamma-aminobutyric acid.

Neurotransmitters are chemicals that help pass messages between nerve cells in your brain. GABA helps pass nerve messages that have a calming effect on your brain.

By boosting the effect of GABA, Xanax helps reduce nervous tension and feelings of anxiety. The drug makes you feel more relaxed.

How long does it take to work?

Xanax starts working about 30 minutes to 1 hour after taking a dose.

This drug comes with several precautions. These are considered drug-condition interactions.

FDA warnings

This drug has boxed warnings. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). It alerts doctors and patients about drug effects that may be dangerous.

Risk of misuse and addiction: Xanax has a risk of misuse and addiction. With misuse, a drug is taken for a purpose or in a way that a doctor has not prescribed. Misuse can lead to addiction, which is when you’re unable to stop taking a drug, even though it may be causing harm. To learn more, see the “Xanax misuse and addiction” section.

Risk of dependence and withdrawal: Xanax has a risk of dependence and withdrawal. With dependence, your body becomes reliant on a drug to function as usual. Dependence can lead to withdrawal symptoms if you suddenly stop taking the drug. For more information, see the “Xanax dependence and withdrawal” section.

Risk of severe harm or death if taken with opioids: Taking Xanax with an opioid may cause severe side effects. These can include excessive sleepiness, breathing problems, coma, and in rare cases, death. Due to these risks, doctors will typically not prescribe Xanax with an opioid unless no other treatment options are suitable.

Opioids are powerful drugs that are also known as opiates or narcotics. They include strong prescription pain relievers, such as hydrocodone (Hysingla ER) and certain illegal drugs. For more examples, see the “Xanax interactions” section.

If your doctor does prescribe Xanax with an opioid, they’ll prescribe the lowest possible dosage of both medications for the shortest possible time.* Be sure to tell people you live with, your caregiver, and people close to you that you’re taking these medications together. You or another person should call 911 right away if:

  • you become very sleepy or unresponsive
  • your breathing becomes slow and shallow
  • your breathing stops altogether

Also, you should not drive or perform other potentially dangerous activities, such as operating machines, until you know how the drug combination affects you.

For more information about this boxed warning, talk with your doctor.

* Your doctor may advise you to have naloxone (Narcan) nasal spray on hand to help treat a known or suspected opioid overdose. They can prescribe the drug, or you can purchase it over the counter at a pharmacy, To learn more, talk with your doctor or pharmacist.

Other precautions

Before taking Xanax, talk with your doctor about your health history. Xanax may not be right for you if you have certain medical conditions or other factors affecting your health. These include:

Allergic reaction: If you’ve ever had an allergic reaction to Xanax or any of its ingredients, your doctor will likely not prescribe Xanax. Also, if you’ve ever had an allergic reaction to other benzodiazepine drugs, such as diazepam (Valium) or lorazepam (Ativan), your doctor will likely not prescribe Xanax. (Xanax is a benzodiazepine drug.) Taking Xanax could cause another allergic reaction. You can ask your doctor what other medications may be better options for you.

Older age: If you’re age 65 years or older, you may have an increased risk of side effects with Xanax. These include sleepiness, dizziness, and problems with coordination that may raise your risk of falls. Due to these risks, your doctor will likely prescribe a dosage of Xanax that’s lower than usual.

Liver problems: Your liver breaks down Xanax in your body. If you have a liver problem, such as alcohol-related liver disease, Xanax may build up in your body. This can increase your risk of side effects. Due to this risk, your doctor will likely prescribe a dosage of Xanax that’s lower than usual.

Kidney problems: Your kidneys help remove Xanax from your body. If you have a kidney problem, such as kidney failure, you may have an increased risk of side effects with Xanax. Your doctor may prescribe a Xanax dosage that’s lower than usual.

Breathing problems: Xanax can cause breathing problems, such as slowed breathing. If you have a lung or breathing problem, such as chronic obstructive pulmonary disease (COPD) or sleep apnea, Xanax could make your condition worse. You can talk with your doctor about whether Xanax is right for you.

Depression or bipolar disorder: Xanax may worsen depression or cause episodes of mania in people with depression. If you have a history of depression or bipolar disorder, talk with your doctor about whether Xanax is right for you.

Breastfeeding: Breastfeeding is not recommended while taking Xanax. For more information, refer to this article.

Pregnancy: Xanax may not be safe to take during pregnancy. For more information, refer to this article.

Note: For more information about the potential negative effects of Xanax, see the “Xanax side effects” section.

Taking more than the recommended dosage of Xanax can lead to serious side effects and, in rare cases, death. Do not take more Xanax than your doctor recommends. (For information on the recommended dosages of Xanax, see the “Xanax dosage” section.)

Overdose symptoms

Symptoms of an overdose can include:

  • sleepiness
  • confusion
  • problems with coordination and balance
  • reduced reflexes
  • coma

What to do in case of overdose
