I started taking this medicine for a UTI I'm allergic to penicillin and I see that this is in this medicine, that's real great. Well the first night I took it, I was so tired all I wanted to do is sleep, I had the worst headache ever which made me moody and my neck and back just ached. On the second day I woke up and it felt like needles going through my feet they were swollen and itchy and red, i knew right then to quit taking the medicine and yet it spread to my hands and it was the same thing! Still have had a headache 24/7 since i started the medicine. It doesn't help! Look at all the other reviews! Don't take this medicine you take medicine to help you not make more problems! I will never take this medicine again!
