Hello this is Silvia Garcia, I'm 20 and I've been taking the sulfameth for the urinary infection and now, I got so sick and was feeling nauseous which ending up refusing to eat and started seeing things in a slow motion. I also had a hard time to breathe and there were other times, I got dizzy or sometimes blackout per second, I'm worried. Is it the medicine's side effect, should I seek help for it?
