Interaction reference

GLP-1 receptor agonists with Antibiotics

Most antibiotics have no direct interaction with GLP-1 medications. The practical concern is overlapping GI side effects — both can cause nausea and diarrhea.

You can take a short antibiotic course on a GLP-1 — but expect amplified GI upset, and stay hydrated to protect kidney function.

Also known as: amoxicillin, azithromycin, doxycycline, ciprofloxacin

Per-GLP-1 breakdown

Wegovysemaglutide 2.4 mg
Monitor
Mechanism: GLP-1s slow gastric emptying, which can modestly alter the rate (not extent) of oral antibiotic absorption. The bigger issue is additive GI toxicity and dehydration risk, which can stress the kidneys — relevant because severe GLP-1 GI side effects have been linked to acute kidney injury.
What to do: No need to stop your GLP-1 for a routine antibiotic course. Watch for compounded nausea, vomiting, and diarrhea; aggressive hydration matters because volume depletion on a GLP-1 can cause acute kidney injury. If vomiting is severe, contact your prescriber — antibiotic and GLP-1 absorption both suffer.
