You can use Wegovy (semaglutide) as long as needed for weight loss. This is if your doctor agrees it’s safe for you and you’re able to tolerate Wegovy’s side effects.
The Food and Drug Administration (FDA) has approved Wegovy for weight management in people with obesity or people with overweight and at least one weight-related health condition. It’s used in adults and children ages 12 years and older. Wegovy is prescribed along with increased physical activity and a reduced calorie intake.
This article looks at how long you might use Wegovy for weight loss, what results you might expect, and what might happen if you stop using it.
You inject Wegovy under the skin of your abdomen, upper arm, or thigh. You’ll take it once per week, on the same day of the week. You can take Wegovy at any time of day, with or without food.
Can I start Wegovy at 1.7 mg?
No. The recommended starting dose for Wegovy is 0.25 milligrams (mg). You’ll need to take 0.25 mg once per week for the first 4 weeks of treatment.
Starting at this dosage reduces the risk of side effects from Wegovy. If you tolerate the initial dose, your doctor may gradually increase the dosage as follows:
- Weeks 5 through 8: 0.5 mg
- Weeks 9 through 12: 1 mg
- Weeks 13 through 16: 1.7 mg
Wegovy’s maintenance dose
The typical maintenance (long-term) dose for Wegovy is 2.4 mg. Your doctor will prescribe you this dose after you reach your goal weight. If you don’t tolerate the 2.4-mg maintenance dose, they may reduce the dose to 1.7 mg.
Your doctor will be able to determine the best dosage for you after you hit your weight loss goal.

Below is information on what results to expect with Wegovy treatment.
First-month results
A 2021 study found that, on average, people lost more than 2% of their body weight in the first 4 weeks of using semaglutide. (Semaglutide is the active ingredient in Wegovy.) For example, if a person weighs 200 pounds (lb), a 2% reduction in body weight means they would lose 5 lb.
Keep in mind that the amount of weight you lose with Wegovy and how fast you lose it varies from person to person.
Long-term results
A
At 104 weeks, 67.8% of participants using semaglutide had lost 5% of their body weight or more and 44.2% of participants had lost 10% or more. This was compared with 21.3% and 6.9% of participants, respectively, who used a placebo. A smaller percentage of participants using semaglutide had lost 15% to 25% of their weight or more at this point in the trial.
Semaglutide also reduced major cardiovascular events — including heart attack and worsening of heart failure — by 20% in people without diabetes who had cardiovascular disease, overweight, or obesity.
If you have questions about what results to expect with Wegovy, talk with your doctor.

Ways to increase weight loss with Wegovy
Here are five possible ways to increase weight loss while using Wegovy:
- Reduce your calorie intake: Reducing your calorie intake by
500 kilocalories per day may support weight loss. - Increase your physical activity: Aiming for at least 150 minutes of moderate-intensity exercise per week can help increase weight loss.
- Eat nutrient-dense foods: Nutrient-dense foods provide important vitamins and minerals and are lower in added sugars, saturated fats, and salt. Nutrient-dense foods help provide your body with the nutrients it needs without excess calories.
- Manage stress: Stress
can change food intake and fat storage, potentially leading to weight gain. Finding healthy ways to manage stress may support weight loss. - Get quality sleep: Poor sleep
may increase the risk of obesity and increase energy intake. Getting enough sleep may help with weight loss.
Reasons you may not lose weight with Wegovy
Possible reasons you may not be losing weight while using Wegovy include:
- Reaching a plateau: After an initial weight loss, a plateau may occur at roughly
60 weeks of treatment. - Needing to give it more time: Significant weight loss with Wegovy is gradual. It can take more than a year to lose almost 15% of your weight with the highest dosage.
- Taking other medications:
Other medications , such as beta-blockers, some diabetes drugs, and antipsychotics, may cause weight gain.
If you’re using Wegovy and not losing weight, you can talk with your doctor about factors that could be preventing weight loss. In some cases, your doctor may suggest changing your Wegovy dosage or taking a different weight loss drug, such as tirzepatide (Zepbound).
Wegovy is a long-term treatment that you may use indefinitely to maintain weight loss or until you cannot tolerate the side effects. If you stop using Wegovy, you may regain weight that you lost. If you had preexisting cardiovascular or metabolic conditions, these may also return.

If you want to stop using Wegovy, it is important to continue any other lifestyle changes you’ve made to support weight loss, such as eating a reduced calorie diet and increasing your physical activity. You can talk with your doctor about how to stop Wegovy safely while avoiding weight regain and preventing health conditions from returning.
Wegovy is a long-term treatment for weight loss that you may continue to use as long as you’re able to safely manage any side effects.
Your doctor will gradually increase your dosage until you reach a maintenance dose. This is the dose you’ll keep taking to sustain weight loss.
If you’d like to stop Wegovy, talk with your doctor about how to do so safely. To help prevent weight regain, it’s important to continue with any healthy lifestyle changes you’ve made.
