I was just prescribed Ciprofloxacin 250mg tablets for a urinary infection. I have just had back surgery 5 weeks ago and am on a lot of medications, including Norco for pain, Amlodopine, Losartan, Nexium, Advair 250/50, Singulair, and Xyzal as well as Lasix and potassium, are there any interactions I need to be aware of. I have Pulmonary Hypertension, Asthma and GERD
