Can You Take Antibiotics While on Mounjaro?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 22nd, 2026.
Yes, you can generally take antibiotics while using Mounjaro (tirzepatide). Most antibiotics don't interact with GLP-1 receptor agonists like Mounjaro, as they work through different mechanisms in your body. However, some antibiotics like fluoroquinolones may affect blood sugar levels, which could be relevant since Mounjaro also impacts glucose control. Additionally, if antibiotics cause nausea or stomach upset, this might compound Mounjaro's common gastrointestinal side effects like nausea, vomiting, or diarrhea. Consult with your healthcare provider before starting any antibiotic while on Mounjaro to ensure the combination is appropriate for your specific health conditions and to discuss timing strategies that minimize potential stomach irritation.
