I was prescribed this drug for a UTI. I've been on it for 6 days already (10 day treatment) and thankfully have not experienced the severe side effects that some people on this site have. I noticed that a few of the entries mentioned that people with penicillin allergies shouldn't be put on this. I'm surprised that my doctor put me on it in that case, but I haven't really had any allergic reactions to it. However, I have had a few minor side effects. A couple days ago, I had a horrible headache. As for anxiety/depression, I was suffering from that anyway due to real life circumstances so it's impossible for me to tell whether or not the pill had any effect on it (I don't think so, because I feel fine now). As for ongoing side effects, I have actually felt extremely gassy lately, and I know it has nothing to do with my diet. The first day on this pill was fine, but after that I started experiencing this problem. I also had some diarrhea when I first started on it. Well, I'm done with this pill in four more days. The good news is that it COMPLETELY cured my UTI and I definitely feel much better than I did when I was running to the bathroom every five minutes.
