The short answer
You can take a short antibiotic course on a GLP-1 — but expect amplified GI upset, and stay hydrated to protect kidney function.
Use with cautionUsually fine — watch for specific effects
Why it matters
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.
Ask your prescriber
“I take Antibiotics. Is Foundayo (orforglipron) safe with it, and what should we monitor?”
