I have an appointment Tuesday morning 11am for a prostate biopsy. At present on heart meds: Metoprolol Er Succinate 100mg,(once a day), Enalapril 20mg (twice a day, Hydrochlorothiazide 25mg (one a day), and in the evening take before bedtime, Atorvastain 20mg. My Urologist, informed me to have an Enema the day before the procedure, and to take 1 Tablet twice a day, on Monday of: Ciproflaxin 500mg. As Ciproflaxin is a potent tab, I am gravely concerned after reading up about this medication.
