Anyone take this before and had side effects? Apparently there are LOTS of side effects which I have read about, but all I *think* I have is terrible headaches. It doesn't affect my stomach of GI tract at all. Only side effect might be the headaches.
The headaches could be from something else, but also can be a side effect of Keflex. Anyone experience headaches in particular with this antibiotic? I'm trying to figure out why I have these bad headaches; saw neurologist yesterday and all was ok from his standpoint.
