GLP-1 shots and antidepressants: what to know

Many people take a GLP-1 weight-loss medicine and an antidepressant at the same time. They can work together, but you should know three simple things first.

You may take a GLP-1 medicine for weight loss. You may also take an antidepressant for your mood. Can you take both together? Yes, many people do. But there are three simple things to watch. Let us look at them clearly.

Both medicines can upset your tummy

GLP-1 shots slow down your stomach. This is why they cause nausea. The Wegovy label lists nausea as a top side effect. About 44 in 100 people got nausea on Wegovy. Antidepressants can also upset your tummy. SSRIs like sertraline are known for this. About 26 in 100 people got nausea on sertraline. So taking both can add up. Your tummy may feel more upset than with either one alone.

Nausea rates: see them side by side

Wegovy (semaglutide, a GLP-1 shot)
About 44 in 100 people got nausea. About 24 in 100 got vomiting.
Sertraline (Zoloft, an SSRI antidepressant)
About 26 in 100 people got nausea. This is the most common side effect.
Contrave (naltrexone/bupropion weight-loss pill)
About 33 in 100 people got nausea. This pill already has an antidepressant (bupropion) inside it.

GLP-1 weight-loss medicines cause depression and suicidal thoughts.

mostly false

Mostly false — explained simply. In April 2024, Europe's medicine experts checked this carefully. They said the evidence 'does not support a causal link.' So no proven cause was found. America's FDA also found no clear proof. The FDA said it 'cannot definitively rule out a small risk.' So it kept watching. So no proven link exists today. But if your mood drops, tell your doctor right away. That is just good sense.

The bottom line

You can take a GLP-1 and an antidepressant together. Watch your tummy and your mood. Never mix weight-loss medicines on your own. Always talk to your doctor first.
