My physician s office is now closed. She prescribed Ciprofloxacin HCL 500mg twice daily for an upper respiratory issue that may be mild pneumonia. I picked up the meds today and the pharmacist has me concerned about taking this medication indicating kidney issues, ligament issues, possible yeast infection (I m female). I take Triamterene HCTZ, Metoprolol, Lipitor, a baby aspirin at night and Xanax before bed. I m now frightened to take the antibiotic which I know is so important for getting back to good health. I ve been reading and am concerned about taking the diuretic with this new medication and other possible drug interactions. I m also wondering if it s OK to take 325 mg aspirin. Fever is currently just a little over 100. I m a 67 year old female.
