Sulfamethoxazole / trimethoprim
"I was originally prescribed levoflaxcin for a bad sinusitus  After a week nothing was happening. I was kept on it another week and still nothing. Then the doc gave me The sulfmeth tri.  I have been bed ridden for 7 days.  Body aches dizziness, Nausea, minor Vomiting. I literally feel like I was hit by a train.  I have 7 days left but that is it. I'm done.  I will not put this crap in my body again.  It has been a nightmare."
