Hi, I have been prescribed an antiobotic called smz-top dis for possibly a urinary tract infection. Levaquin nearly killed me a few years ago. Thus I am reluctant to take it. The pharmacist suggested that it may interact negatively with other melds that I take daily. These meds include: metformin, glimeperide, metoprolol, amlodopine, losartin, aspirin therapy. Should I be concerned?
