SMZ-TMP DS and flu

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.

Great! After reading these posts I can expect this awful monster like rash to last a couple of weeks???? I was prescribed Bactrim DS 800-160 mg twice a day and I thought it sounded like a large dose. Developed flu like symptoms on day 3 with racing heart, achy body, stomach and muscle cramps. Woke up today (day 6) with itchy hives ALL over my body. Got a cortisone shot at urgent care clinic and taking benadryl. No change in my condition yet. Why don't they take this sh_t off the market? I could have died from it. I have used Bactrim many times for UTI over the years but was never prescribed this super dose which did this to me!!

On Dec 21 2008 my 17 years old was prescribed SMZ/TMP DS 800-160 Tab for possible staph infection. She is/was to take 2 tablets every 12 hours for 10 days. By day 5 of this dosage, she had severe flu symptoms. Took her back to the same Doctors office but saw a different Doctor and was informed that she was only supposed to take 1 tablet every 12 hours for 10 days. She has been taking the the correct dosage for 3 days and the flu symptons are not as severe, as of today her skin is a little red (like too much sun) but not bumps or hives. We will continue to watch closely. Hopefully she will make it to day 10 without anymore problems. She does not want to go back to the same Doctor's office again.

I was prescribed /TWP DS 800-160 for a urinary infection. I have taken this medication before with no ill effects, but this time my hands itch all the time and I have a red, itchy rash on my back and stomach. I finished the prescription today, ao hope it goes away and so far the UTI I had is better. At least I don't have as much pain, but it required two prescriptions before is worked. I have taken this before with no noticeable effects. Is this serious?
