If you’re searching for weight management options, you might consider asking your doctor about Wegovy. It’s a prescription drug used along with lifestyle management (low calorie diet and exercise) for long-term weight loss in adults.
A doctor may prescribe Wegovy if:
- you have a body mass index (BMI) of 30 or higher, or
- you have a health condition related to weight (e.g., type 2 diabetes, hypertension, hyperlipidemia) and a BMI of 27 or higher
The active ingredient in Wegovy is semaglutide. (An active ingredient is what makes a drug work.) It belongs to a group of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists.
Wegovy comes as a liquid solution in a prefilled single-dose injection pen. You’ll give yourself the drug as an injection under your skin.

What are the usual dosages of Wegovy?
The information below describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. They’ll determine the best dosage to fit your needs.
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 stop your treatment 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 have you stop Wegovy treatment.
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 the missed dose. But if your next scheduled dose is in less than 48 hours, skip the missed dose and give yourself your next dose at the usual time. Then, you’ll continue with your weekly schedule.
If you miss your weekly Wegovy injections 2 weeks in a row, call your doctor. They can discuss your options with you to get you back on track with your dosing schedule.
If you need help remembering to inject your dose of Wegovy on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone.
