Cefuroxime
"I'm in the last couple of days of a 10-day prescription for cefuroxime (Ceftin) to treat acute prostatitis and mild bladder infection.  The pain and discomfort subsided 3-4 days after beginning treatment.  I've been managing the loose stool problem with multiple small portions of yogurt during the day.  I'm also experiencing mild irritability and anxiety while taking the drug, a fair trade-off compared to my symptoms before starting treatment."
