Sulfamethoxazole and fatigue

I began taking this medication at a dose of 800mg twice daily 3 days ago. Today I began experiencing extreme anxiety, hot flashes, redness of the skin, itching and fatigue. I am taking this medicine along with another medication (cephalexin 2000mg daily), for a staph infection. How long will this reaction continue and what is the best way to manage the symptoms of these antibiotics?

I was prescribed Sulfamethoxazole and Trimethoprim for a sinus infection. After taking it for 3 days I felt worse than I had felt the entire month of feeling sick. I had weird dreams, chills , cold sweats,headaches ( where the headaches weren't before) little sleep but super tired and very bad nausea . I quite taking it the next morning and felt extremely nauseous, sore from shaking all night , emotional and fatigue. So glad I found this website. I felt like I was losing it.

MY 13 YR OLD DAUGHTER WAS PUT ON SULFAMETH FOR WHAT I THOUGHT WAS A SPIDER BIGHT, THE DOC CALLED IT MRSA. SHE HAD UPSET TUMMY RIGHT AWAY AND AFTER THE 3RD DOSE SHE WAS WITHDRAWN, SICK TO HER STOMACH, NO APPETITE, AND OVERLY TIRED...AND FATIGUE...THRU THE TOP. I TOOK HER OFF OF IT RIGHT AWAY. AWFUL STUFF, I WOULD NEVER SUGGEST IT FOR ANYONE.

Prescribed to Sulfameth Tuesday March 20, 2 a day for 10 days, for an abscessed spider(not actually positive that it was) bite after having it lanced and drained.

Started with a massive global headache, and slight fatigue. Then moved to extreme nausea and feeling like my throat was closing, shortness of breath. Followed shortly thereafter by vomiting, loss of appetite, disconnection from the world... Basically everything every other negative testimonial has mentioned with the exception of the rash...

Either way this drug is trash. I stopped after only 4 doses. Today being Saturday, 3 days after stopping, the vomiting stopped yesterday but the horrible stomach cramp is still present. I am slowly getting my appetite back but any foods I look at look terrible and don't taste right. I can't drink anything but water without feeling like there is a nasty film in my mouth. I hope this subsides before my 21st birthday next tuesday or I'm going to be pissed. Never taking sulfa drugs again.

I was prescribed Sulfameth for an inflamed cyst on my back. It was a 10-day prescription. The first symptom a few days after starting was unusual fatigue. This was followed by severe itching on my feet, though initially I didn't make the connection between the itching and the antibiotics. This itching then moved to my testicles, and the day after the prescription was finished I noticed redness on my testicles, small red splotches on my penis, and a large red splotch on my left elbow. At first I thought it was psoriasis, but I have no history of that and the only change in my usual physical/dietary regimen is the Sulfameth.

Extreme headache, back pain, extreme pressure and pain in sinus, fatigue but unable to sleep, dizzy spells. Took medication for three and a half days for an infection but will discontinue today

yes i am having the same flu symptoms and today i broke out in a body rash. had a headache yesterday and body chills. skin sensitivity, head ache, dizzyness, loss of appitite, sleeplessness, fatigue, nausea. i believe it is an allergic reaction. glad i found this place so now i know i'm not sick like i thought i was. i have three days left on the medicine and i'm not going to continue to take it

I started taking SULFAMETH / TRIMETHOPRIM 800/160 for my UTI. While being on it for only 2 days I started to get cold chills, severe head aches (sort of like migraines), fatigue and itching all over my body. I can't believe that this is the side effects to something that supposed to cure you!

The doctor at the university gave me this for my sinus infection. Thank God it was only a five day prescription. I'm on the last day as we speak. I ran into this site while searching for side effects. My symptoms have not been as severe as others. Headache, fatigue, stomach ache, and an uncontrollable appetite. I'm drinking water but not that much. Only around 40-60 ounces a day which is obviously not enough. I've been staying up very late at night. Bedtime is around 4-5 in the morning. Last night I noticed redness on my gums. When I brushed my teeth and used mouthwash it burnt like all hell. My gums feel better today. It hasn't been fun but I will say the medicine did its job. I don't feel the "rock" in my throat anymore thats for sure. Which is well worth the price concerning the side effects.

both my brother and i have been taking sulfameth for almost a year for our acne. it works great and the only side effects we experince are slight fatigue and dry mouth.

I was prescribed sulfameth for a sinus infection. I took 15 pills. 2 each day. My symptoms got progressively worse. It started with constipation, weight gain, fatigue (I attributed this to the sinus infection), nausea, irritability. I was having trouble getting to sleep. I constantly had to get up to go to the bathroom. Once I would get to sleep I would wake up every few hours. Around day 5 or 6 I started getting a horrendous headache and my neck ached. The pain was intense! My legs ached as well. I started running a fever around 100 degrees. I would be sweating one moment and cold the next. I thought I was getting a bug that was going around minus the sore throat everyone else had. I was glad that I was already on an antibiotic. Today I woke up and have a rash from my shoulders to my feet! I still have the same fever. I called my nurse practitioner and she said to discontinue the medication, take Benadryl for the symptoms and increase my water to flush it out of my system. It's clearly an allergic reaction to the meds. I am throwing the last few doses out.

I took this drug for UTI almost 10 years ago. A few days after I started taking it, I became extremely nauseaus, losing 10kg (about 22 Lb) in 1 week. I couldn't eat, lost all my energy. Even to this day, 9 1/2 years later, I still suffer side effects from this drug. I cannot absorb vitamin B12, which has also caused pernicious anaemia, and also have anaemia, irritable bowel syndrome, constant nausea, fatigue and am highly susceptible to stomach bugs and food poisonings.
Before taking it, I was fine, perfectly healthy and never had any gastro problems.
But since taking trimeth, I have never been the same.

I was using it for acne. I'd been on it about two weeks when I started having sudden high fever and extreme lethary. (Like if I didn't lay down, I'd fall down). I'd hit the bed for several hours, and wake up feeling improved. Then I'd go through the same thing later that night; fever back up and horrific fatigue. I kept thinking I was coming down with something and even remarked that I was glad I was "already on an antibiotic." Then realized my fevers were shortly after my dose. Nurse said "no, that wouldn't do it. I took one more dose to "see" and in addition to the fever going up, that time my lips swelled and itched. Spoke with the Dr. and he said NEVER to use a sulfa med again, as the next reaction could be quite dangerous.

~ mental confusion
~ severe tingling
~ loss of appetite
~ fatigue

I have been taking this drug for 3 days now and have had SEVERE headaches. They go away with advil or tylenol but come back as soon as they wear off. I have also noticed increase fatigue and loss of appetite.

Constant chills or sweats - mostly sweat, so bad that it was just running off me when I woke up and the pillow and sheets are wet. Total fatigue barely enough energy to get up out of bed then come right bact to lay down. Too fatigued to sit in a chair. Very weak. Total loss of appetite.

high fever, fatigue and vaginal itch :(

very nauseated- lack of appetite. fatigue
