Amoxicillin / clavulanate
"I never had a problem with regular Amox 875, I asked doc to prescribe regular Amox for a recent upper respiratory -- instead I got this 'enhanced' version.  What a mistake. Every cough resulted in stress incontinence including severe explosive diarrhea. My overall symptoms got worse -- asthmatic bronchonitis with wet cough developed. This went on for 2 1/2 days until I read the side-effects and read the caution to IMMEDIATELY stop the med if severe diarrhea due to potential GI problem it can trigger. Never again, will I take this med."
