“Took this medication the first thing I noticed was a pain in my stomach next thing I noticed it had me throwing up or vomiting about 10 to 12 times back to back. I couldn’t get warm put on pyjamas got under thick covers next thing I noticed I couldn’t breathe and hardly make it to the front door ended up calling 911 emergency. Immediately gave me a breathing treatment Benadryl took me to the emergency room continued breathing treatment Severe allergic reaction Found out After later research This medication is banned in Europe”

“Please don't let anyone scare you into not taking this. If you're like me with new medicine, you go online and research every little side effect and review and convince yourself not to take it. I was really scared to take this as I had bad reactions to Macrobid and Ciprofloxacin, and after reading these reviews I just knew it was going to be the same way. I'm on day two, no side effects other than a little nausea and a headache. That's the worst of it. We'll see how it goes by day 7, but so far this has been the best antibiotic I've taken.”

“Went to the ER on Friday had the worse UTI infection ever which had spread to my kidneys & who only knows what other organs because the pain is absolutely unbearable! My 2nd day of Bactrim thus far pain has subsided some but still there. Haven't had any side affects yet I guess time will tell. I lost my mom last year to a very bad UTI infection so for anyone that has 1 please don't put off getting help.”

“I was diagnosed with a Kidney infection and prescribed Bactrim twice a day for 5 days. I took my first pill in the evening, slept for twelve hours and took another one in the morning. I thought my body just needed the rest, but shortly after the second pill I slept most of the day. By the end of my experience I've had: fatigue, stomach pains, severe constipation, nausea, insomnia, and loss of appetite. My kidneys seemed to have improved but I couldn't even bring myself to take the final pill.”

“I was prescribed this after having kidney surgery. I took one pill and felt fine. But the next day, I took a 2nd dose and within an hour I had the worst vertigo that I have ever experienced. Everything was spinning. Even when I laid down, if I moved even a little, I felt like the pillow was falling. Its been 24 hours, the vertigo passed but very tired and have a headache.”

“Took this medicine for a horrible horrible HORRIBLE kidney infection. Worked within 2 days and cleared up all of my symptoms, which was such a relief. I was told to finish off the bottle by my doctor, and the next day I developed a horrible case if the hives. I stopped taking the medicine immediately, but the hives stuck around for another 3 days. What a miserable week! So, Bactrim worked wonders for my kidney infection, but little did I know I was severely allergic to it. Take with caution.”

“Took 2 Bactrim daily for UTI after 3 prescriptions of Keflex with no change to infection. Bactrim did cure the persistent UTI but I ended up in hospital and tests showed my kidneys were not working. So was effective cure but serious side effects. After 4 days in hospital kidneys are back to functioning”

Frequently asked questions

Sarah · Taken for less than 1 month September 15, 2019

“I was prescribed Bactrim after a UTI turned into a kidney infection. The Bactrim wiped out enough of the infection so that I became functional again. However, I wrote this review to warn people prescribed this drug of the following: - I got severe back pain about a week into my 2 week course of Bactrim. It only happened one day and may have been caused by something else. - I was out in the sun for only a few hours in a tropical place while on Bactrim and got the worst sunburn of my life. I couldn't sleep for 2 nights because the pain and the itch was so bad. Take the warnings about photosensitivity seriously and stay out of the sun or you will be at risk of getting a severe sunburn (Do a computer search on this to see how bad it can get. No doctor properly warned me of this). - I got UTI symptoms again about a week after my 2 week course was done. I'm now on another antibiotic.”

“Really effective, but really terrible side-effects. UTI and kidney infection both cleared up quickly, which I'm grateful for, and ultimately that's the point. But I had nausea and vomiting, dizziness, diarrhea, joint aches, itchy skin, sore throat, loss of appetite... I felt way better with the infection than I did on the medication. But it's all temporary.”

“Horrible medication. Vomiting, skin rash --headache-- joint pain. Can barely get off toilet knees hurt so bad Sore throat. I was ok until I took 1 pill. I'm worse from taking it. Should be classified as poison not medication.”

“I was a bit of a moron and let a UTI go for too long. I had pain on and off for a few months in my back. Pee was cloudy, frequent urination..all that good stuff but two days ago I woke up and felt absolutely terrible. I was so nauseous, couldn’t eat anything, awful headache, chills and the worst back pain I had ever felt. I went to Dr and she wrote this for me. I took two pills yesterday and already today I feel a 100x’s better. I don’t believe it is for everyone obviously due to the mixed reviews and my mother had taken it before and it had awful effects on her as well but I do believe it’s worth trying because for me it’s been wonderful. I couldn’t even bend over yesterday and today all I have is slight dull pain in my back.Worked perfect”

“I had sharp back pains and a 101 fever with nausea, and was put on levaquin for 7 days. I am soo sensitive to meds that I had to change to Bactrim after one day. Bactrim has been a dream!! I have had little to NO side effects which is huge. Pharmacist said drink PLENTY of water on this so I have been. Dry mouth/weird taste in mouth but no feeling weird or having stomach issues.”

“I had a UTI that went into a kidney infection, They put me on Bactrim, Didn't notice any side effects until a few days later, I started feeling depressed out of no where and it got worse from there, I ended up in the hospital with the worst headache of my life, I was shaking and throwing up I didn't even think it had anything to do with the Bactrim. The depression got so bad I ended up at the psychiatric hospital, I had no idea why I was feeling like this, it was by far the worst feeling in the world, When I came home and went to see my therapist and told her what was going on she immediately asked me what medicine they put me on and when I told her she said look up the side effects to that and sure enough everything was listed.”

“I was prescribed Bactrim for a kidney infection. I took two doses, 500 mgs each. After the first dose, I began to feel lousy. I assumed it was a side effect. The second dose almost killed me. I went to the ER, where I was stabilized enough to move me to ICU. Before I lost consciousness, my blood pressure was 35/27. I woke up 3 days later with a central line, severely swollen body, and my skin was bright red, like a severe sunburn. I spent 3 weeks in the hospital, with my blood pressure constantly plummeting. I apparently have a severe allergy.”

“Rushed to the ER because of unbearable flank pain. Doctor noticed a large amount of white blood cells in the urine, and prescribed Bactrim. The first two days I felt okay, nothing really improved. By the fifth day the back pain disappeared but the urge to pee was still present. Sixth day I got a high fever, headaches, body aches, and a rash. Felt like crap! Stopped taking it and side effects subsided. I'm severely allergic to Bactrim. Was prescribed Cipro, it works great!”

“My Dr prescribed Bactrim for my kidney infection along with Steroids. I'm supposed to take Bactrim twice a day for 7 days. Being told I would feel better after two days. This is day 7 and if anything, I feel worse than before I started the Bactrim. I go back to the Dr on Monday. I'm terrified he will want to hospitalize me.”

“I was prescribed bactrim twice daily for a week for a suspected kidney infection. I only got through two and a half days of the medication before I stopped taking it because I was so tired I couldn’t function and my skin became sore in certain places. I was taking 3-4 naps a day and my muscles were so weak I had to sit to even brush my hair. I am 28 weeks pregnant and a mother to a 20 month old so there is no way I could get through a week of not being able to function. I couldn’t even hold my daughter without having to sit down.”

“I got sick the day after Christmas. Thought i was just having nausea, but it progressed to a very painful tummy and back so I went to the er with my husband a few days later. I had a kidney infection, so they put me on the generic for bactrim for 10 days. I felt no different till a few days in, and that's when I got some relief but also side effects such as persistant and constant nausea, and headaches. Wasn't too bad. Then I felt excited on my last day because I truly felt better (minus stomach cramps that I didn't think were serious at the time). But then less than 24 hours later I started feeling bad again with my back and tummy, so we went to the ER and they put me on the generic for macrobid. This is day one of that. We'll see how it g”

“This is a great medication as long as you are not allergic to Sulfa. Don’t let these posts scare you away from trying it. Hard to tell symptoms of infection vs side effects”
