Divalproex oral tablets are a generic prescription drug that’s FDA-approved to:

  • Treat manic episodes or mixed episodes related to bipolar disorder. Bipolar disorder is a type of mood disorder that involves manic episodes and depressive episodes. When symptoms of both mania and depression happen at the same time, this is called a mixed episode. Divalproex treats both manic and mixed episodes in adults.
  • Treat epilepsy. Epilepsy is a condition that causes repeated seizures. Epilepsy can cause many different types of seizures. Divalproex is specifically used to treat complex partial seizures or absence seizures that happen with or without other seizure types. For this purpose, divalproex may be used alone or with other antiepileptic drugs in adults and children ages 10 years and older.
  • Prevent migraine. Migraine is a condition that causes a severe headache along with other symptoms (such as nausea and vomiting). Divalproex is used to help prevent migraine in adults.

Drug details

Divalproex belongs to a group of drugs called antiepileptics. You’ll take divalproex oral tablets by mouth.

Divalproex oral tablets come in two forms:

  • delayed release (DR) tablets, which are called divalproex DR
  • extended release (ER) tablets, which are called divalproex ER

DR tablets are made with a special coating. This coating keeps the tablet from releasing the drug into your system before the tablet passes through your stomach. ER tablets, on the other hand, release the drug slowly into your body over time.

Divalproex DR oral tablets come in three strengths: 125 milligrams (mg), 250 mg, and 500 mg. Divalproex ER oral tablets come in two strengths: 250 mg and 500 mg.

Note: Divalproex also comes as oral capsules. This article addresses only oral tablets. For information on divalproex oral capsules, talk with your doctor or pharmacist.

Brand-name versions

Divalproex DR oral tablets are available in a brand-name form called Depakote. Divalproex ER oral tablets are available as brand-name Depakote ER.

Effectiveness

For information about the effectiveness of divalproex oral tablets, see the “Divalproex oral tablets uses” section below.

Divalproex oral tablets are a generic drug. A generic drug is an exact copy of the active drug in a brand-name medication. Depakote and Depakote ER are the brand-name medications that divalproex oral tablet is based on. A 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 using Depakote or Depakote ER instead of divalproex oral tablets, talk with your doctor. They can tell you if Depakote or Depakote ER come in strengths that can be used for your condition. If you have insurance, you’ll also need to check whether your plan will cover Depakote or Depakote ER.

To learn more about how generics compare with brand-name drugs, see this article.

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

Drug strengths

Divalproex oral tables come in two forms:

  • delayed release (DR) tablets, which are called divalproex DR
  • extended release (ER) tablets, which are called divalproex ER

DR tablets are made with a special coating. This coating keeps the tablet from releasing the drug into your system before the tablet passes through your stomach. ER tablets, on the other hand, release the drug slowly into your body over time.

Divalproex DR oral tablets come in three strengths: 125 milligrams (mg), 250 mg, and 500 mg. Divalproex ER oral tablets come in two strengths: 250 mg and 500 mg.

Dosage for manic or mixed episodes related to bipolar disorder

Divalproex DR oral tablets are used to treat manic episodes related tobipolar disorder. Divalproex ER oral tablets can be used for both manic and mixed episodes related to bipolar disorder.

For these uses, the typical starting dosage of divalproex DR is 750 mg per day. The usual starting dosage of divalproex ER is 25 milligrams per kilogram* (mg/kg) of body weight per day. For example, a person who weighs 60 kg (about 132 pounds [lb]) would start by taking 1500 mg of divalproex ER per day. Your doctor will instruct you on when (and how often) you should take your dose.

The maximum recommended dosage of divalproex is the same for the DR and ER oral tablets: 60 mg/kg of body weight per day.

* 1 kg equals about 2.2 pounds (lb).

Dosage for complex partial seizures, with or without other seizure types

Divalproex oral tablet is used to treat complex partial seizures that happen with or without other seizure types. For this purpose, divalproex may be used alone or with other antiepileptic drugs (the drug group divalproex belongs to).

For this use, the typical starting dosage is the same for divalproex DR and divalproex ER. You’ll start by taking 10 to 15 mg/kg* of body weight each day. For example, a person who weighs 50 kg (about 110 lbs.) would start by taking 500 mg to 750 mg of divalproex each day. Your doctor will instruct you on when (and how often) you should take your dose.

If you miss a dose, take your missed dose as soon as you remember. But if it’s almost time for your next dose, just skip your missed dose and take your next dose at its usual time.

Don’t take any extra doses of divalproex to make up for a missed dose. Doing so can raise your risk for side effects from divalproex.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or timer on your phone or downloading a reminder app. A kitchen timer can work, too.

Will I need to use this drug long term?

Whether you’ll use divalproex oral tablets short term or long term depends on the condition you’re using the drug to treat.

For manic episodes related tobipolar disorder, you may use divalproex as a short-term treatment. After the symptoms of your manic episode have resolved, your doctor may switch you to a different drug for long-term use.

For its other uses, divalproex oral tablets are typically given as a long-term treatment. If you and your doctor determine that divalproex oral tablets are safe and effective for you, you’ll likely take them long term.

The Food and Drug Administration (FDA) approves prescription drugs such as divalproex oral tablets to treat certain conditions. Divalproex oral tablets may also be used off-label for other conditions. Off-label drug use means using a drug for a purpose other than what it’s been approved for by the FDA.

Here are answers to some frequently asked questions about divalproex oral tablets.

Is divalproex a narcotic?

No, divalproex isn’t a narcotic. Divalproex belongs to a group of drugs called antiepileptics.

“Narcotic” is a term used to describe opioids, which are used to treat severe pain. Unlike opioids, divalproex isn’t a controlled substance.

Controlled substances are drugs that the federal government closely regulates. These medications have a risk of misuse. (Misuse means taking a drug in a way other than how it was prescribed.)

But these effects aren’t known to happen with divalproex. If you have questions, talk with your doctor or pharmacist.

Will divalproex make me feel ‘high’?

No, taking divalproex shouldn’t make you feel “high.”

But feeling high may be a symptom of a manic episode related tobipolar disorder. Manic episodes are periods of extremely high energy and excitement that affect your daily life.

Divalproex is used to treat manic episodes related to bipolar disorder. So the drug should ease any symptoms of mania you may have, such as feeling high.

If you’re concerned about feeling high after taking divalproex, talk with your doctor.

Is divalproex used for anxiety, depression, or schizophrenia?

Divalproex isn’t currently approved to treat anxiety, depression, or schizophrenia. But the drug may be used off-label for these conditions. Off-label drug use means using a drug for a purpose other than what it’s been approved for by the Food and Drug Administration (FDA).

If you’re interested in using divalproex to treat anxiety, depression, or schizophrenia, talk with your doctor. They can help determine the best treatment for your condition.

Can I take divalproex to help me sleep?

Divalproex isn’t currently approved to help with sleep.

Divalproex can affect people differently. Both sleepiness and insomnia (trouble sleeping) are possible side effects of the drug. So it’s possible that divalproex may help you sleep. But the drug may also keep you awake.

You’ll know more about how divalproex affects you after you’ve taken the drug for several days.

To learn more about using divalproex for sleep, or about other treatment options, talk with your doctor.

Is divalproex an antipsychotic drug?

Divalproex may be used to treat mental health conditions, but it’s not an antipsychotic drug.

Antipsychotics are a class of drugs that are mainly prescribed to treat certain mental health conditions, such as schizophrenia and bipolar disorder. (A drug class is a group of medications that work in a similar way.)

Divalproex is used to treat manic episodes or mixed episodes related tobipolar disorder. It belongs to a drug class called antiepileptics.

If you have questions about using divalproex and how it works to treat your condition, talk with your doctor.

Divalproex oral tablets belong to a group of drugs called antiepileptics.

Divalproex’s mechanism of action (the way it works) isn’t fully understood. The drug is thought to increase the level of a chemical called gamma-aminobutyric acid (GABA) in your brain. Higher levels of GABA are thought to help ease symptoms of mania, treat seizures, and help prevent migraine.

How long does it take to work?

It may take 1 to 2 weeks for divalproex to start working. You may “feel” the drug working during this time, but it may take longer for symptoms to reduce in some people.

Clinical studies didn’t look at how long it took divalproex to start working. If you have questions about whether divalproex is working for you, talk with your doctor.

Using more than the recommended dosage of divalproex oral tablets can lead to serious side effects and, in rare cases, death.

Do not use more divalproex than your doctor recommends.

Overdose symptoms

Symptoms of an overdose of divalproex oral tablets can include:

  • excessive sleepiness
  • heart block (problem with the heart’s electrical signals that may cause it to stop beating for a short amount of time)
  • high level of sodium in your blood
  • coma

What to do in case of overdose

If you think you’ve taken too much of this drug, call your doctor. You can also call the American Association of Poison Control Centers at 800-222-1222 or use its online tool. But if your symptoms are severe, call 911 or your local emergency number, or go to the nearest emergency room right away.

There aren’t any known interactions between divalproex oral tablets and alcohol. But it may be best to avoid alcohol while taking divalproex. This is because both divalproex and alcohol can cause dizziness and drowsiness. Drinking alcohol while taking divalproex may worsen these side effects.

If you drink alcohol, talk with your doctor before taking divalproex. They can advise you on whether it’s safe to drink alcohol while taking the drug.

Divalproex oral tablets can interact with several other medications. 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.

Divalproex and other medications

Below is a list of medications that can interact with divalproex oral tablets. This list does not contain all drugs that may interact with divalproex.

Before taking divalproex oral tablets, 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 divalproex oral tablets include:

  • Carbapenem antibiotics. Taking these medications with divalproex can make divalproex less effective. Examples of carbapenem antibiotics include:
  • Hormonal birth control. Taking divalproex with hormonal birth control can make divalproex less effective.
  • Certain other antiepileptics (the drug group divalproex belongs to). Taking divalproex with other antiepileptics can make divalproex less effective. It can also affect your risk for side effects from either drug. Examples of antiepileptics include:
  • Nortriptyline (Pamelor) or amitriptyline. Taking divalproex with these drugs can raise your risk for side effects from amitriptyline or nortriptyline.
  • Clonazepam (Klonopin). Taking divalproex with clonazepam may cause certain seizures to last longer than usual.
  • Propofol (Diprivan). Receiving propofol while you’re taking divalproex may raise your risk for side effects from propofol.
  • Rifampin (Rimactane). Taking divalproex with rifampin may make divalproex less effective. Your doctor may adjust your dosage of divalproex if you take these medications together.

Before using any of these drugs with divalproex, talk with your doctor or pharmacist.

Divalproex and herbs and supplements

There aren’t any herbs or supplements that have been specifically reported to interact with divalproex. But you should still check with your doctor or pharmacist before using any of these products while taking divalproex.

When to take

You’ll likely take divalproex DR two or three times per day. Divalproex ER is taken once per day.

Try to take your doses around the same time each day. This helps make sure you have a consistent amount of the drug in your body. Your doctor will give more specifics on when you should take your doses.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or timer on your phone or downloading a reminder app. A kitchen timer can work, too.

Taking divalproex with food

You can take divalproex with or without food. But if the drug upsets your stomach, you can try taking it with food to relieve your discomfort.

Can divalproex oral tablets be crushed, split, or chewed?

No, you shouldn’t crush, split, or chew divalproex oral tablets. You should swallow the tablets whole.

Divalproex is used to treat complex partial seizures or absence seizures that happen with or without other seizure types. Divalproex may be used alone or with other antiepileptic drugs in adults and in children ages 10 years and older. (Divalproex is a type of antiepileptic drug.)

Examples of other drugs you may use with divalproex include:

  • clonazepam (Klonopin)
  • diazepam (Valium)
  • ethosuximide (Zarontin)
  • lamotrigine (Lamictal)
  • phenobarbital
  • carbamazepine (Carbatrol, Epitrol, Tegretol)
  • phenytoin (Dilantin)

It’s important to note that if you take these drugs with divalproex, your doctor may adjust your dosage of divalproex or of the other seizure drugs. This is because divalproex can affect the level of other seizure drugs in your body. And other seizure drugs can also affect the level of divalproex in your body.

Your doctor will adjust your dosage as needed if you take divalproex with other seizure drugs.

Tell your doctor right away if you become pregnant while using divalproex. They can discuss with you the risks and benefits of continuing divalproex treatment. They may also recommend a different treatment option for your condition during pregnancy.

Other precautions

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

  • Gastrointestinal (GI) problems. Before taking divalproex, tell your doctor if you have any GI (digestive) problems, such as having an ileostomy or colostomy. If you have a GI condition, divalproex may not break down completely in your body. If this happens, you may notice a portion of the divalproex tablet in your stool. This could mean your body isn’t absorbing the right amount of drug needed to treat your condition. If you have certain GI problems, your doctor may prescribe a drug other than divalproex for you.
  • Liver problems. Before taking divalproex, tell your doctor about any liver problems you have. The drug can cause serious liver problems for some people. Your risk for this side effect may be higher if you already have liver problems.
  • Mitochondrial disorder. If you have mitochondrial disorder, tell your doctor before starting divalproex treatment. This condition can raise your risk for serious liver problems with divalproex. If you have this condition, your doctor may prescribe a drug other than divalproex for you.
  • Urea cycle disorder. With urea cycle disorder, your body has trouble getting rid of a chemical called urea. Urea is made from ammonia, which forms in your body after it breaks down protein. Divalproex can cause a high level of ammonia in your blood. So your risk for this side effect is even higher if you have urea cycle disorder. If you have this condition, tell your doctor before taking divalproex.
  • Allergic reaction. If you’ve had an allergic reaction to divalproex or any of its ingredients, you shouldn’t take divalproex oral tablets. Ask your doctor what other medications are better options for you.
  • Pregnancy. It isn’t safe to use divalproex while pregnant. For more information, see the “Divalproex oral tablets and pregnancy” section above.
  • Breastfeeding. It may not be safe to breastfeed while taking divalproex. For more information, see the “Divalproex oral tablets and breastfeeding” section above.

Note: For more information about the potential negative effects of divalproex, see the “Divalproex oral tablets side effects” section above.

If you have unused medication that has gone past the expiration date, talk with your pharmacist about whether you might still be able to use it.
