Quick answer
Can you take Saxenda with Amoxicillin (Amoxil)? Minor interaction — usually manageable with awareness, no formal contraindication. Mechanism: No clinically significant pharmacokinetic interaction. Pharmacodynamically, antibiotic-related GI side effects (nausea, diarrhea) can compound liraglutide's GI profile. Short-course use is generally well tolerated.
