Sulfamethoxazole / trimethoprim "I was prescribed Septra for a bacterial infection. The prescription was for ten days, and about the fifth day, I had a headache that started with severe lower back pain also. On the seventh day, I broke out from head to toe with severe hives."

"I started this medication sulfamethoxazole/trimethoprim five days ago for a urinary tract infection. It was a three-day dose. I finished it two days ago, but have felt very weak, anxious, and bad headaches. I'm not sure if this is normal now that I have finished the medicine."

Sulfamethoxazole / trimethoprim "I was prescribed Bactrim and Keflex to treat a traumatic force injury to my shin, which a month later turned into a bacterial-type infection. I was on these 2 antibiotics for 3 doses (100 mg Bactrim), and I got small spots of hive-like bumps under both forearms, on my hand, and on the backside of the injured shin. They took me off those antibiotics, and without taking any other medicines yet that day, approximately 8 hours later, I looked like I had the chickenpox. It's Day 3 after stopping Bactrim, and I'm just starting to get some relief from the intense itching (I did have a steroid IV today to try to help this)."

Sulfamethoxazole / trimethoprim "I had possible strep throat. First day I took it, my fever rose to over 102. I was shaking, chills, rash. My blood pressure (and I have high blood pressure) was 100/55, and my pulse was 50. I was not feeling well at all. I called the doctor the next morning, and he switched me to Amoxicillin. I hope it works better. Now I have an under-the-skin rash all over and am itching. Guess I am allergic to this one."

Sulfamethoxazole / trimethoprim "First time I got MRSA, it started as a small pimple under my arm and quickly became a massive abscess overnight. I went to the ER, and the doctor told me it was MRSA and prescribed me 10 days' worth of Bactrim. Within four days, the infection stopped, and the wound started to heal. It was completely healed before the ten days, but I took all the Bactrim as directed by the doctor. Then about 7 days ago, I noticed a large pimple and got it checked, and it was MRSA again, but my whole leg was swollen. They lanced it and gave me another ten days of Bactrim. I'm about five days in, and the swelling has subsided, and the pain is much less. No side effects other than a constant headache and abdominal cramps. Seems to work well for MRSA and staph infection."

Sulfamethoxazole / trimethoprim "My father was given Bactrim for a bad urinary tract infection, and it put him into kidney failure. My daughter took Bactrim for a staph infection under her arm, and she was so sick she could not get out of bed for most of the treatment time. Avoid this if at all possible, and make sure your doctor is aware of all of your diagnoses. It did do its job, especially with my daughter, she could see results the next day."

"Do your research before taking this medication (sulfamethoxazole/trimethoprim). I was prescribed this medication for an ear piercing (rook) that rejected. I was supposed to take it for 10 days/2x daily. The first 3 days, no symptoms; however, the next two days I started feeling like I was coming down with the flu/cold. I experienced body aches, low-grade fever, headaches, and a mild sore throat, as well as some unsteadiness. After experiencing these side effects, I stopped taking the medication. I’m waiting for my doctor to contact me with further instructions. But I will not be taking the remaining pills, and I’m never taking this medication again. BTW: My ear looks and feels much better."

Sulfamethoxazole / trimethoprim "Being immunocompromised by steroids taken for another ailment, I contracted a bacterial infection (disseminated nocardiosis) that spread throughout my body - brain, kidney, lung. (AKA: sepsis) Initially, I was hospitalized on an IV of a liquid form of Bactrim for 30 days, followed by 11 months on oral Bactrim at 3,200 mg/day. No noticeable side effects. It saved my life."

Sulfamethoxazole / trimethoprim "I am taking Septra for an infection on the tip of my nose. Day one was horrible. Nausea, fatigue, and vertigo (felt like a flu). That lasted one day. Days 2-7 have been without issues. I take it with a meal and a good 12-16 ounces of fluid. Three days to go, and I expect that will be fine. My infection appeared much better by the 4th day."

"I used Bactrim as part of a bacterial infection I got from my sinuses. I have never needed to drink more water in my life. I went through roughly 4-6 bottles of regular-sized water every single hour (think normal grocery store brands). I took this medication for a week and a half. This resulted in me drinking around an entire 48-pack every single day. It sounds ridiculous, it really does, but that’s how much I drank. To this day, I’m well, the antibiotic helped me so much, but I still can’t believe how thirsty it made me. If I didn’t drink a bottle of water around every 10 minutes or so, my mouth and throat would completely dry up and I wouldn’t hardly be able to breathe. Never experienced anything like that, I felt like a manic OCD, with my compulsion just being “water drinking.”"

"I've been taking this for a UTI, and I believe it's helping with that, but honestly, all the side effects are taking over to the point where my UTI is the last thing I'm thinking about. Major nausea, I have to lay in bed all day. It always feels like I could vomit. It's made my anxiety so bad. I keep having panic attacks at night, and it has kept me up all night thinking. My nausea has been the worst at night, too, so really not getting much sleep. Really not worth it."

"My doctor put me on sulfamethoxazole in hopes of clearing up a mild but recurring skin infection under my arms. I was instructed to take 2 pills per day for 2 weeks. My first, second, and third day I felt okay, but the fourth - ninth day (today) I have felt very tired, shaky, and dizzy. When I turn my head a certain way, or lay down, I feel as if I spun in a circle ten times, then stopped. I called today and spoke with a nurse who assured me that I would have had the side effects the first or second day. Well, I know my body, and I don't feel right. So today will be my last day on this."

"I was put on Bactrim for acute prostatitis. I took it for two weeks, and I have never been sicker in my entire life. I had jitters, sweats, severe nausea, and vomiting. I would deal with that, but I have had uncontrollable anxiety and muscle pain in the back of my legs. I have been off of it for a week, and the leg pain and anxiety are still out of control. It caused a mild rash on my sides after taking it. This is the worst thing I have ever taken. I have been in the emergency room three times while on this. I was told by doctors to finish two weeks' worth. I will never take this again."

Sulfamethoxazole / trimethoprim "I'll be honest, I was not expecting much from Bactrim, but it definitely helped me. Bactrim alleviated my joint and epididymitis pains, amongst other things, including clearing my skin. Unfortunately, at the 6th day of treatment, I began to get itchy and called my doctor, who informed me I must be allergic to it. I'm sad since it worked, and while it was working, I felt fantastic and healthy. It took some time to work (about 5 days). Aside from the itchiness, I didn't experience any additional side effects. I was even sleeping better, but that was most likely due to it getting rid of the bacteria causing my systemic infection. Give it a go if you receive a script for it! Currently on the quest for finding an alternative that works just as well, if not better. Bear in mind when reading reviews about any antibiotic that the negative effects of it could be due to an allergic reaction, and that just because someone else is allergic to it (and had a bad anaphylactic reaction at that) does not mean you are!"

Sulfamethoxazole / trimethoprim "Taking for abscessed tooth. It seems to be working so far. Although it is very slow, it seems. Thankfully, I have experienced no side effects like a lot of these other people, so hopefully it gets the job done in the end. So far, so good."

Sulfamethoxazole / trimethoprim "I have a small either cyst or some type of mass on the back of my neck under the skin. Doctor said it could be due to some type of staph. He prescribed me Bactrim, aka sulfameth. trimethoprim. He said two weeks to take this, and if it does not go away, we will need to lance it. Which in a way, I'm glad, it bothers me. Anyways, I went to the pharmacy to get my medicine and went home. I actually started the same day taking my pill. Friday, Saturday, and Sunday I felt okay. But come Monday, about 3 a.m., I got up and had diarrhea. Multiple times I felt nauseous and achy. At 7 a.m., I felt it in my throat, I vomited, and after that, I had a horrible headache. Can't eat, I feel as though my joints are stiff. Doc is changing my meds. No sulfa again!"

"Honestly, this drug worked GREAT for me! I didn't have any side effects whatsoever. I had a bacterial infection on my armpit, and it was there for 2 weeks until I took Bactrim. It flushed it out within a week or so, without any problem."

"Online doctor prescribed this for my UTI. After day 1 my symptoms are (1) periods of lethargy, feeling drowsy, napping, significantly lower energy/motivation (2) insomnia (unable to sleep more than 3 - 5 restless hours a night; I was already a light sleeper before, UGH); (2) stomach pain. I already had acid reflux issues, but now my stomach will feel bloated and painful. DEF take with A LOT OF WATER and food to prevent side effects. I took a giant horse pill 2x a day. I think this dosage is too big for me (I'm 100 lb). I have 2 days left and cannot wait for this to be over. I've been unable to concentrate; working/getting anything done is basically impossible (I almost called in sick today, but I WFH due to COVID, so was able to nap when needed). I didn't know antibiotics could have so many side effects. The older UTI antibiotics, I didn't have any side effects, so missing that experience. It is making the UTI better, tho. I do not recommend this based on my experience."

"I had to stop taking it after 5 days. I hadn't had panic attacks in years, and I do take Zoloft for them. I appreciate reading others' experiences because I really thought I was losing my mind. I haven't had any for 4 days and still feel a little off. Now I'm probably fretting over how I feel... which isn't good if you're prone to panic!"

"I had an abscess. I got the generic type of Bactrim, sulfamethoxazole. I only took 3 pills total, in two days, each followed by moderate cramps and diarrhea. The second night after taking the 3rd pill, my lips and throat became swollen and had purple patches on them. The skin is thin and near splitting. I have white, patchy, slimy stuff in the back of my throat, which is thrush. My joints hurt, I have waves of chills that come on and can't get warm. It hurts to swallow, my tongue is swollen and sore also. The worst, however, is my mental state, feeling massive anxiety and temper swings at nearly nothing. I sort of had an outburst on my daughter and wife, and I feel terrible about it. I won't take this again. Now I'm taking Benadryl to reduce swelling."

"Been taking this sulfamethoxazole/trimethoprim for 5 days now due to strep. I was fine until today. Now my body aches all over, my joints keep popping and aching, as well as my muscles. I have jaw pain and headaches. Don't know if this is the bacteria die-off symptoms and I should keep on. Calling the doctor tomorrow. If I know I'm not in serious trouble, I will keep going. But I don't know if this is an allergic reaction or something completely normal when destroying the bacteria in your system."

Sulfamethoxazole / trimethoprim "I was given a three-day supply of Bactrim for my post-vasectomy recovery. I've just finished the second of two days, and so far, so good. One side effect, though, and it may be an accidental benefit, it's cleaning me out-in fact, everything feels better, and things are more normal in consistency. I haven't increased or changed my diet in the last few days, just increased output, and I feel better overall."

Sulfamethoxazole / trimethoprim "I saw so many negative comments and got so scared, but my doctor insisted that I'll be okay, and it really was okay for me. I was taking it for an intestinal bacterial infection since nothing helped me for a week, and I felt horrible. This helped me right away, after the first dose. I was taking it for 5 days, and I was completely healthy after just 2 days of taking it, along with some probiotics and other medications."

"This sulfamethoxazole & trimethoprim antibiotic combo medication took away some symptoms of a UTI. Normally, I am prescribed Macrobid, which I notice works miraculously hours after taking the first tablet. I moved and have a new doctor who prescribed me this medication instead of Macrobid. I decided to try it and hoping it would work even better than Macrobid. It took 3 days of treatment until I noticed my symptoms of a UTI subsiding. After taking a final tablet of treatment, a day later symptoms of a UTI returned. Had stomach issues, itchy skin, and felt hypersensitive to touch. Will not be using this medication again."

Sulfamethoxazole / trimethoprim "The reviews of this medication had me absolutely terrified, but a few of the positive reviews gave me the courage to try it. So I felt obligated to share my review to help calm the fear of others. I took this medication twice a day for seven days. I took it with food, and I also took one Florastor probiotic capsule with every Bactrim pill. I felt fine for the entire seven days. No side effects whatsoever. That being said, there is a long list of the types of people who should NOT take Bactrim. I recommend anyone taking this medication look up the warnings and contraindications and speak with a pharmacist if they have any questions. Best wishes, everyone!"
