Wegovy and probiotics: the verdict

Generally fine when taken together

The Wegovy label does not list any interaction with probiotics. According to the NIH, probiotics are generally safe for healthy people, but the risk goes up if your immune system is weak.

What the Wegovy label says

No line on probiotics. For anything you drink, the warning that matters most is kidney injury from fluid loss. That fluid loss can lead to kidney injury. Heavy fluid loss should be reported, and you should drink fluids.

The practical rule

If you are seriously ill or your immune system is weak, ask your doctor first.

Probiotics with other GLP-1s

Probiotics are not named in the drug interaction section of any of the 10 GLP-1 labels, so the answer is the same for the whole class.

The same question is asked about Ozempic, Mounjaro, Zepbound.
