Does Wegovy® (Semaglutide) Cause Insomnia?

No, Wegovy does not cause insomnia or difficulty sleeping. If after starting the medication you notice that you are having trouble sleeping, there are various reasons why this may be happening. Have you made any changes in your life or habits that could affect sleep, such as increased caffeine or alcohol intake? Are you under increased stress?  If there is no clear trigger, be sure to discuss this with your doctor, as there may be other reasons why you are having trouble sleeping.  Although Wegovy does not cause insomnia, keep in mind that stimulant weight loss medications, such as Adipex-P® (phentermine), are more likely to cause insomnia, especially if taken later on in the day.
