For Diverticulitis "Have been on Bactrim now for 9 days with the 10th day almost completed, for an intestinal infection. Around day 7, I started feeling achy with a mild fever and chills. I’ve also had some gastrointestinal uneasiness, headaches, and insomnia. Basically, the intestinal issue is resolved, so Bactrim did its job. But others should be aware of the side effects. I have to admit I had not fully informed myself about them. Side effects can be very uncomfortable, and I suppose that if they were much worse, they even could be dangerous."

For Bacterial Infection "I have not had a good experience using Bactrim. The first day's dosage caused no side effects, however, by day 6, I had headaches, severe heartburn, nausea, chills, severe muscle weakness, depression, anxiety, and generally felt unwell. I took each dose with a full glass of water and a full stomach, as recommended. I am supposed to take this for 4 more days, but I will call my doctor for an alternative treatment."

For Bacterial Skin Infection "Ugh, this medicine is the absolute worst I’ve ever experienced in my life. I know everyone is different, but my experience was brutal! Horrible dizziness, nausea, anxiety through the roof, chills, sweats, memory loss. I literally freaked out on the nurse helping me. I screamed, “I’m having a stroke!” It was like something came over me, like an out-of-body sensation. I got really dizzy, and it went blurry. Scary symptoms to have! Hopefully, nothing lingers. My doctor has to look up side effects because he said he didn’t know of many and was surprised to find nervousness, psychosis, and hallucinations being possible. Freaky experience! So now I am out on clindamycin for the MRSA."

For Urinary Tract Infection "UTI - Bactrim for 7 days. Day 1 stomach discomfort. Day 2 UTI slight urgency but manageable, that night had an anxiety attack and heart palpitations. By day 4 exhausted, hardly able to do my daily work. I called my doctor on day 5, and she said this is normal - to just power through, and since I’m allergic to penicillin, I’m likely not allergic to Sulfa. That night had chills and a 100-degree fever. Day 6 I felt even worse (chills and fever) and developed hives. Was told I have a Sulfa allergy and to stop with the meds and start Macrobid. The next day with Bactrim leaving my system I developed a full body rash that made me look sunburned and had a 103-degree fever. The rash subsided 6 days after it started, and my other symptoms ended 3 days after I stopped the pills. Overall, one of the worst medical experiences of my adult life. Macrobid seemed to work, only symptom was head fog, which may have been from Bactrim. Giving Bactrim 2 stars because it seemed to clear the UTI."

For Urinary Tract Infection "Listen! No! Heck no! Absolutely NOT!!! I was prescribed Macrobid, but itching started and my face felt numb just after the 2nd dose!!! So my doctor switched me to Bactrim! I will say the first 2 pills weren’t so bad. Little nausea, slight headache. But baaaabbbby, this 3rd pill is the awful! I’m currently shivering as I type this. I’m in a robe and under covers. Make it make sense. Prior to this, I had a scare... my heart rate increased so high!!!! Talk about a rapid beating out of nowhere, I FREAKED out!!!! I should’ve read the reviews and listened! I didn’t listen... thinking I’d have a better outcome. I had 3 pills left. I’m not taking that!! I’ll keep drinking my water and flushing my system because the symptoms were milder than the antibiotic!!!! We all are different indeed, but dang how can your body handle this stuff? Still shivering, by the way. I was given this twice a day for 3 days."

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 "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 a 5-day course of Bactrim to get rid of a UTI. Giving it a 5 rating because it worked, but I have been so sick since taking it. I have flu-like symptoms, chills, sweating, dizziness, and severe nausea. Tylenol helps with the head and body aches. I took my last dose yesterday and still feel like garbage. Hope it gets better soon."
