Back in Novemeber 2007 my wife was prescribed Bactrim for Ance. About 6 days into taking the drug a rash broke out all over her body.
A lymph node in the back of her head on the right side swelled. She had stiffness in neck, nausea, cold sweats, irregular bleeding. Just horrible! I researched the side affects and found sites like this on with people having similar reactions. I immediately told my wife to get off Bactrim.
1 to 2 days later her lymph node was normal. It took weeks for the rash to completely go away. Since this
happened it seems as though my wife's immune system has not been the same. She had severe sinusitis, She's has a cold now. Still has fatigue. Bouts with headaches. Strange stuff. Not sure if it is related.
I don't recommend this drug to anyone. Whatever your ailment is there are alternatives.
