i have just been perscried sulameth 800/160 two pills a day. for a kidney infection. i was on another med that this is a lesser dose of called laqu something and on that i took only one pill and i was very dizzy couldnt stand or drive and as i tried to sleep my bed was spinning.so i coldnt close my eyes. everything i ate or drank came back up. so the dr gave me this and i know read about this and i hope i dont get the side effects. why would they have this med on the market if it does this to people? should we do something about it we do have enouph proff of it being a bad drug. think of all the people in the world who we could stop from feeling like u guys. i just took my 1st one then came to look 4 sides and relly hope that i dont get it. i am a relly small person as is i only weigh 95 heathy pounds i am short as well though 5 3' think of how i might really hit a smaller person like myself. i will write back to update u guys on how i feel.
