<<Disclaimer: Verify this information before applying it to your situation.>> Hi All-- I've been on an antibiotic (Avelox) for four weeks for chronic sinusitis; the ENT wants me on it another two weeks. I take it with a full meal, usually lunch, but now after so long, even with a meal it upsets my stomach - in a *big* way! I normally take papaya (sp?) enzyme tablets after accidental gluten ingestion or the infrequent times I just have a tummy upset. Does anyone know what effect the papaya would have on the efficacy of the antibiotic if I took the papaya after I took the Avelox? (I don't think I can face another two weeks of nausea every day...) Thanks. Ayn/Kansas
