Possible Side Effects
- Mounjaro makes you feel full by acting like two of the body’s natural hunger hormones, GLP-1 and GIP. Because one way it does this is by slowing your digestion, its side effects are mostly to do with the gut.
- Mounjaro weight loss injections aren’t known to directly disturb sleep; there’s no official Mounjaro sleep side effects.
- However, some people taking it do report having issues getting to sleep. Though this doesn’t appear to be common: in a scientific review of social media posts, around 1% described experiencing insomnia while on weight loss medicines such as Mounjaro. Here, sleep troubles might be a knock-on effect from other symptoms, like constipation or mental health side effects.
- On the other hand, tiredness is a Mounjaro side effect. That means that Mounjaro might actually make you feel sleepy! There’s also research suggesting that it could help with sleep apnoea (more on this later).
- ## Is insomnia a side effect of Mounjaro?
- Not officially. Insomnia has not been reported in clinical studies. But as we mentioned earlier, it might be brought on by other Mounjaro side effects.
Contact your healthcare provider if you experience any concerning symptoms.
