For Bacterial Skin Infection "I had a facial abscess lanced at urgent care and prescribed Bactrim in case it was MRSA. I took it for about 8 days twice daily and lost my appetite, got headaches, and felt anxious and depressed. I continued to get cystic acne behind my ears, mostly the ear by the abscess that was drained, so the dermatologist PA told me to take Bactrim for another month, once a day. I took it another 12 days until I began having knee joint pain and achiness in my legs like I've got the flu. Oh, I was also getting the chills. I've been off it 3 days and still having very bad leg pain that's caused me to have a panic attack and extreme mood swings and depression. I know it's from this antibiotic... I'm praying that the pain goes away as it is debilitating and I was a healthy 30-year-old prior to this."

For Bacterial Skin Infection "I was prescribed Bactrim after having an abscess on my leg drained. I started feeling horrible immediately. Joint pain, nausea, loss of appetite, high fevers. I ended up in the hospital for 3 days for drug fever and am still feeling the effects a week after coming home. I would not suggest taking this."

For Bacterial Infection "Do not take Bactrim, the side effects are awful. My side effects were that I was dizzy, my mouth was so sore I could hardly eat. Had bad leg pains, no appetite, nausea, headaches, I would break out into a sweat. I stopped taking this, been off of it 3 days, and still feel terrible. Never take this again!!!!"

For Urinary Tract Infection "This antibiotic works quickly to get rid of UTI, but my main side effects are stomach pains and loss of appetite. I have one more dose to take, and then I’m finished, thank God. I’m taking the 800 mg."

For Bacterial Skin Infection "Was prescribed Bactrim-DS BID for 10 days for an infected cut on my wrist from punching glass. The first 2 days were HORRIBLE. I was tachycardic, nauseous, gassy, itchy on arms/legs, and had no appetite, jaw clenching, and severe panic attacks. Plus, my symptoms were just getting worse. I was forming clusters of stinging/itching blisters around my cuts, my wrist was swollen and warm to the touch, and I felt feverish. I ended up getting prescribed Keflex to take with Bactrim starting Day 3. Side effects subsided and symptoms got better. Some nights, I'd wake up at 3 AM with a panic attack that lasted until I took my next dose. Other nights, I'd be able to sleep just fine. Days 6-7, I got gas pain that felt like chest pain. The side effects didn't get better until Day 8. By then, all I had was some itchiness but no full-on rash. I never want to take this drug again. I give it 3 stars only because it did treat my infection despite taking all 10 days and all my willpower to pull through."

For Urinary Tract Infection "I was prescribed Bactrim after two other antibiotics failed to cure my UTI, and let me tell you, not only did it not work, but I also had a violent allergic reaction to it. I was suffering from my first UTI (first of many to come sadly). The symptoms went away pretty quickly after taking the first pill but came back after I stopped taking the medicine two days later. From what I remember, I got really sick: chills, high fever, nausea, complete loss of appetite, extreme fatigue, and red patches all over my body, but especially on my arms, legs, and chest. I had swollen lips as the first indication, but as I was young, I didn’t understand it at first. When I went back to the doctor, he said it was a pretty powerful medicine and that he knew beforehand that the risk of allergy was higher than with other medicines. I don’t hold it against him though, it was very frustrating not to find anything that would work to cure this UTI."

For Urinary Tract Infection "Just thought I'd share my experience with Bactrim. I'm a petite girl. As far as side effects go, I had almost none the first few days, but now on my 4th or 5th day, I am noticing the side effects appearing! Which are (for me) headaches, constipation (watch what you eat with this or else you'll get blocked up), loss of appetite (I'm not hungry almost at all), and oddly enough, pain when I breathe in (possibly mild pericarditis). I also can't seem to focus. But nothing too horrible. I take this on an empty stomach every time, and it is absolutely fine. But, 3 out of 10 pills left, and I still have symptoms of a UTI! Ugh. So maybe it did not work for me."

For Urinary Tract Infection "On this Bactrim, I had no appetite, was extremely fatigued, and constipated. On the third day, I woke up and realized that I was unable to pass urine. By the time I got to the ER, they had to use a catheter to remove 12 liters of urine. The ER doctor insisted it was not a side effect, but there is no way I will ever take this again!"

For Bacterial Skin Infection "I was just prescribed this antibiotic today due to a staph infection in each leg from shaving. My doctor mentioned MRSA, needless to say, I'm freaking out over this. Regardless, it's been about 4 hours since I took the first pill - obviously, the infection sites haven't gotten any better, but I'm hoping they do. As far as side effects go, I'm lucky so far to only have a little bit of heartburn and slight nausea/loss of appetite. I'm crossing my fingers this stuff works for me!"

For Prostatitis "I went to the doctor for prostatitis and was prescribed Bactrim (sulfamethoxazole). Some background, I have high-functioning anxiety and decided to write this review while I wait for my doctor to call me back about changing antibiotics. These other reviews are 100% accurate about severe anxiety (heart rate over 90 BPM 24/7), headaches, loss of appetite, and nausea... nothing better than throwing up stomach bile because you can't eat. I thought I had COVID but tested negative... On the bright side, after 3 days, my prostatitis went away, I guess it's a double-edged sword."

For Urinary Tract Infection "Started Bactrim 800 mg DS on a Wednesday. Thursday afternoon had a 103 fever. Fever would reduce with NSAIDs. Fever has been present every day since. The major side effects I experienced were fever, chills, body aches, cough, loss of appetite, feeling dehydrated, severe fatigue, and change in urine volume. I thought maybe I had COVID, got a test. (No COVID.) Original UTI symptoms (kidney area pain) were gone by day 3. I’m on the last day of the script, and I will NOT take this again."

For Urinary Tract Infection "I was prescribed Bactrim DS 2x a day for a UTI that wouldn’t go away after trying to treat it with cranberry. I became horrendously ill after the 2nd pill, muscle aches, muscle weakness, dizziness, rapid heart rate, feeling faint, and feeling like I couldn’t concentrate. Tried calling my doctor to ask if I could go down to one pill a day as 2 felt too much, they didn’t call me back until 3 days later because of the weekend. By then, I took it upon myself to only take one pill a day, and my doctor said that was a good decision. With one pill a day, the most I felt was a slight headache and slight loss of appetite, but my UTI symptoms continued to get worse, so I was put on Cipro. Praying the Cipro works for me now."
