SMZ-TMP DS and allergic reaction

My doctor prescribed this drug to me on 5/07/09. I started I the first pill around 1:00 pm (one pill twice a day). While at work around 3:00pm I noticed my face was a little red, didn't think much of it. By the time I went home around 5:00 pm my face was really red and was hot to the touch. I thought since it was the first really warm day outside and after traffic I was just a little warm. I was complaining about my right leg hurting and told my husband "it sucks getting older, every thing hurts) - I am 40. Around 7-8 pm my back started to itch (nape area) and my husband said there were some bumps like acne, I didn't think so because they were like burning/itching. I was getting really tired and took my second pill around 11:00pm (mistake), all of a sudden I felt like I was getting the flu, I ran to bathroom (barely made it) and I was burning up, headache, and aches/pains. I called my doctor in the morning and was told not to take any more and I was allergic to this medication. Needless to say, it is 1:00am on 5/09/09 and my headache finally went away and the pain in my right leg is down to a dull pain now. I don't understand why this medication is still out there, it should be taken off of the market soon.

i was prescribed this drug for kidney and bladder infection. i avoided sunlight ( warning on drug label). my skin began to look thin and dehydrated, tingling sensations. my face became swollen and cheeks exceptionally red, like severe sunburn. it's been over two weeks since i stopped taking this medication and my skin still isn't anywhere back to normal. my face actually became flaky.

i have taken Bactrim in the past with none of the above side effects. how does this drug differ from Bactrim.
