Sulfamethoxazole-Trimethoprim DS and allergic reaction

I had a kidney removed at the age of 19. I recently had a UTI and was prescribed sulfameth/trimeth ds for it. With in an hour after taking the first pill my hands turned bright red and were uncontrollably itching and then the rest of my body started to itch, with in about 2 hours it felt like i had been beaten up my entire abdomen hurt (movement like coughing and breathing hurt the most) By the end of the day when it was time for my second dose i was beginning to get really concerned, but i took the second pill thinking i needed to protect the only kidney i have left. The next day i wasn't able to go to work i was in so much pain in the abdominal area. I also feel light headed and short of breath. I DID NOT receive a drug facts paper with the side effects like u would with any other drug ive ever gotten and im starting to wonder why. So I called the doctors office that prescribed it to me to see if it was an allergic reaction or side effect and it took them 2 days to call me in a new prescription! Heres hoping it didn't harm the kidney i have.

I was prescribed Sulfamethoxazole-TMP tablets for a severe UTI that I developed. I was given 10 tablets total--and instructed to take two per day. Within an hour of taking the first tablet, my UTI felt much better, however, the rest of me felt horrible! I got nausea, dizziness, extreme confusion and depression, and stiffness and pain in my neck and shoulders. I continued the medication anyway, b/c I never had sulfur or ANY medicinal allergies. I had difficulty sleeping the next few nights, I would wake up in the middle of the night for no reason. The soreness of my neck and shoulders then extended to my butt and thighs. I can't describe how uncomfortable this was. I was sitting at work literally writhing in pain from what I felt in my legs. (and I blamed it on my poor desk chair!!) This happened on day three of five. Also, while at work I had an "episode" if you will, where I became extremely confused and disoriented, and nearly had a panic attack. It felt like the world was crashing down on me!! It only lasted for 15 minutes or so, but I will not forget the way I felt. All the while, my UTI symptoms were getting better and better. I was completely unable to have a bowel movement...sorry for this information...but it will start to make you worry if you can't poo for 5 days!! Day four of five is what I like to call "The Enlightenment". I was getting in the shower, still dizzy as hell, and noticed that I was very itchy. I looked at my lower back and I was covered in red, itchy bumps. I was say they looked like small mosquito bites, all in a cluster of about 8 on either side of my lower back. I realized then and there that this medication really was ravaging my body like I had feared. I found this site and others online which confirmed that I wasn't crazy...just poisoned. Later that day I was resting on my couch and looked in the mirror and saw that my entire face was covered in a red rash. (and I got a horrific headache) The worst part is you don't really look outwardly sick or anything...you just feel terrible. Everyone I told was very nonchalant about it..."Oh just take some Benadryl". I've lost my faith in the FDA. I stopped this medication one pill shy of my last dose. I am terrified of the possible lasting effects and will never take this drug again!! PLEASE!! NEVER TAKE THIS MEDICATION!! YOU WILL REGRET IT!!
