What are the usual dosages of Wegovy?

The information below describes dosages that are commonly used or recommended for adults. But be sure to take the dosage your doctor prescribes for you. They’ll determine the best dosage to fit your needs. For children’s dosages, see the “What’s the dosage of Wegovy for children?” section below.

Your doctor will likely start you on the lowest dosage of Wegovy, which is 0.25 mg once weekly. If you do well with this treatment, they’ll likely increase your dosage gradually every 4 weeks. This will continue until you reach the maintenance dosage of 2.4 mg once per week. (See the “Wegovy Dosing Schedule” chart above for the usual dosing routine.)

If you experience certain side effects, your doctor may delay increasing your dose for 4 weeks. Then, they’ll slowly increase your dosage until you reach the maintenance dosage of 2.4 mg once weekly.

If you experience serious side effects at the 2.4 mg dose, your doctor may lower your dosage to 1.7 mg per week for 4 weeks. Then, they’ll again increase your dosage to 2.4 mg per week. If you still can’t tolerate the 2.4 mg dose, your doctor may lower your dosage to 1.7 mg per week. Or they may have you stop Wegovy treatment.

If you have type 2 diabetes, your doctor will monitor your blood sugar levels before you begin Wegovy and throughout your treatment.

What’s the dosage of Wegovy for children?

Wegovy is used to help manage weight in children ages 12 years and older. For this purpose, children must have obesity, which is defined by having a certain body mass index (BMI). Your child’s doctor will determine whether Wegovy is a good treatment for your child based on whether their BMI is high based on their age and sex.

The dosage used in children is the same as the dosage for adults. To learn more, see the “What are the usual dosages of Wegovy?” section above.

For more information about Wegovy’s dosage for children, talk with your child’s doctor or a pharmacist.

Is Wegovy used long term?

Yes, Wegovy is usually used as a long-term treatment. If you and your doctor determine that it’s safe and effective for your condition, you’ll likely use it long term.

If you miss your scheduled weekly injection of Wegovy and it’s been less than 48 hours, give yourself or your child the missed dose. But if the next scheduled dose is in less than 48 hours, skip the missed dose and administer the next dose at the usual time. Then, continue with the usual weekly schedule.

If you or your child misses weekly Wegovy injections 2 weeks in a row, call the doctor who prescribed the drug. They can discuss options to get you or your child back on track with the dosing schedule.

For help remembering Wegovy injections, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone.
