SMZ-TMP DS and rash

I was prescribed this as an inexpensive option to treat a long-term sinus infection in March 2008. I had no prior history of allergic reactions or prior health problems. After 3 days (6 doses) my whole body was in throbbing pain, I felt like my skin was on fire, and I was seeing spots, and had difficulty breathing. I initially had NO RASH or visible/external signs while taking the medication. I immediately stopped taking the medication and saw my doctor, but symptoms persisted for a week. My doctor prescribed prednisone, and had to up the dosage two weeks later when a rash formed over my torso and legs and persisted for 2 months.

The dermatologist gave me Bactrim to treat acne, I took the first pill in the afternoon and at night time I was vomiting and had fever.The next couple of days the symptoms went away but then they came back with itching, rash and lost my taste buds.I stop the medication and I am hoping that this symptoms go away. I guess I am allergic to this medication.

I was taking this medication for 10 days and had a rash all over my body and had to stop taking immediately. The one other side effect is dizziness but besides that nothing else. The rash didn't even itch nor was it raised. I'm now on Macrobid so we'll see how that goes.

I have been on SMZ-TMP for a UTI for about 9 days and I ended up in the emergency room last night for severe rash, and fever of 102. I have had the most horrible back pain, leg pain, cramping, joint pain, muscle weakness and migraine since I started taking it. I thought most of that was due to the UTI/kidney infection and didn't realize that I am allergic to it. I stopped taking it 24 hours ago, and while I still have a slight rash, headache, slight fever and body aches I feel a helluva lot better than I have in over a month. People need to be aware that the sulfur in this drug can cause serious problems.

i started taking SMZ-TMP 400mg/80mg 2 times daily. It helped my Bronchitis but i have also had trouble sleeping and the sweaty hot flashes,and also an annoying headache everyday for the last
9 days. Then today, the last day i'm supposed to take my last 2 pills, i got a rash! They are little red bumps and don't really itch much. I took Benadryl and maybe that helped it not to itch. The rash is on the top of my thighs, on my arms. stomach and back. Pretty much everywhere!

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!!

i have been taking this medication and ive been itching .
nearly scratching my arms off
and making me throw up .
and get sicker than i was

I broke out in a slightly raised rash that started on my chest and spread to my arms, stomach and legs. I thought I had fifths disease except that there was no fever or runny nose before the rash appeared. According to the pharmacy - you can have a severe reaction to it if you are allergic to sulfa drugs (which I am). Next time I won't be so quick to believe everything my doctor says before trying something new..
