I was given the medicine Ciprofloxacin hcl 500mg. I took 3 doses and after the 3 dose I was extremely tired,my muscles hurt, I was stumbling,I had a bad taste in my mouth, felt sick to my stomach. I took my 4th dose and thought I would look at the side effects because that s the only thing that had changed. I seen a lot of these side effects so I stopped taking the medicine. I was on it for a UTI. I haven t started feeling better been off work 3 weeks. My Dr has been running all kinds of tests and blood work. The only thing showing is elevation in the liver from the blood work. I still don t feel good. I still have that bad taste in my mouth and I forgot normally I m cold all the time well now I m hot all the time and I don t carry a fever.
