sinusitis
"Honestly when will people learn that all drugs have side effects but not everyone will suffer with adverse reactions. Yes this is a very strong antibiotic and because it is so strong it can cause some nasty side effects. I’ve used it for sinus infections as well as prostatitis. Slight upset stomach and nausea but compared to having a sinus infection and prostatitis I'd rather take the pill. Don’t let these scare stories put you off taking this med if your doctor has prescribed it. It works wonders."
