Official Answer by Drugs.com

Wegovy (semaglutide) can be injected at any time of the day, but you should only inject it once a week. Choose a day of the week that works best for you to stay consistent with your Wegovy injections.

What is Wegovy Used For?

Wegovy contains the active ingredient semaglutide, and it is used together with diet and exercise for weight loss. It is FDA approved for certain people 12 years and older who have been identified as overweight and have a weight-related condition, or those who have been identified as obese.

Wegovy is also FDA approved to lower the risk of major cardiovascular events, such as heart attack and stroke, in adults with heart disease who are overweight or obese. Most recently, it was approved in adults with metabolic-associated steatohepatitis (MASH), also known as nonalcoholic steatohepatitis.

Should I take Wegovy in the Morning or at Night?

It does not matter if you inject Wegovy in the morning or at night. There is not a specific time to inject Wegovy that would make it work better or help you lose weight faster. Choose a time that you will remember to take your injection on the same day every week. It is important to stay consistent with your injections so the amount of medication in your body remains stable.
