Sulfamethoxazole-Trimethoprim and rash

for everyone who developed a rash, how long did it take to go away? i was on sulfa for three days and now i have little red bumps that kind of look like small pimples all over my ankles and feet and my arms and hands...is this a normal side effect? i am so freaked out that it will be permanent...i stopped taking the meds.

also, i had such bad nausea i couldn't move and could not eat anything

Was prescribed Sulfamethoxazole-Trimethoprim 3 days ago for a bacterial skin infection. At the same time, I also had an apparent allergic reaction going on (unknown source, had never had one before) where my arms were both covered with hives/welts. So my skin was peeling and hive covered BEFORE even starting the meds, which is making the evaluating of the drug side effects a bit trickier. So far, the skin seems to be improving but the hives/rash has not improved, despite taking prescribed allergy meds during the same time. So this could be the current source of the rash, but I can't tell.
On the plus side, have not had any stomach upset (I took all doses w/ food) or other GI symptoms other than increased frequency in BMs. I only seemed to get a headache after not drinking water for a couple of hours. If online sources are to be believed, the "sulfa" portion of this is the culprit behind the worst side effects, AND food may interfere with absorption/effectiveness. Based on that, I'm planning on taking my remaining doses w/ food since the skin infection is already clearing up after 2 days and I've got 10 days to go. Hoping to avoid the reactions folks described here where they starting rashes late in the treatment cycle.

I have experienced nausea with this medicine and I don't know if its normal but my teeth are aching extremely bad, they feel really sensitive. I know antibiotics are bad for your teeth, but I don't know if that's the cause. I have also experienced headaches and slight itching, but no rash thank God!

ok so i have been taking this medicine for a week now due to a uti and it is my 7th day on it and i broke out in a terrible rash that has spread to my torso and arms! i am not sure if it is from the medicine but may be this can help someone out there!

I was wrongly prescribed for a chest infection and came out in a severe rash. Had to go to hospital as it became very bad and itchy. I am now on antihistamine .. never had anything like it ever.. hope this helps. The doctor at the hospital said that it is only usually given to the elderly for urinary tract infections,, so I think I shall be changing my doctor .BEWARE.. .

I am taking sulfameth/trimethoprim and after one week started breaking out in a strange measle-like rash too. this is my first night with the rash, and its not itchy yet but something is definitely wrong. hope this helps the next person.

I had strep throat, they gave me erthromicine- sorry about the spelling- I took it for two days, the worst two days of my life- I threw up constantly, couldn't sleep and gas like you wouldn't believe. Went back to doctor got sulfameth /trimethoprim. Have been taking it for 9 days, twice a day, almost done with the perscription and broke out in a huge rash. My internal temp is very hot but I get the chills and my throat muscles hurt now. Not like strep on the inside but when I turn my head- this sucks!
