For Urinary Tract Infection "Never again! I was put on this for 3 days-2 pills a day for a UTI. I was laid up in bed for 4 days. I was extremely nauseous, chills, sweats, headache, dizzy, couldn’t eat a single thing, and after day 2, I got a SEVERE yeast infection. The pain was unlike anything that has ever happened to me. I took 2 trips to the doctor and over a week to feel somewhat normal again down there. This was way too strong and unnecessary for a simple UTI infection. Never will I ever take this again. I wish I could give it a zero, I am still having nightmares about this drug."

For Bacterial Skin Infection "Prescribe Bactrim 2 days for 10 days for a stye. On the 7th day, I had my allergic reaction. All-over body rash, fever, chills, severe leg pain, chemical burns/ulcers in all soft tissue areas (nose, eyes, mouth, and 'down below'...), abdominal pain, diarrhea, zero appetite, headache, nausea, elevated kidney function test. Bactrim is known and has a long history of hurting more than helping. Stay away!!"

For Urinary Tract Infection "Horrible, horrible medication. I was put on a 7-day course of Bactrim for a fairly mild UTI by local urgent care, and the day after starting my dosage, I experienced SEVERE heightened anxiety, panic attacks, low fever, back tension and pain, uncontrollable shaking, and insomnia. Some hallucinations and nausea as well. After day three, I couldn’t take it any longer and stopped taking it— most of the severe symptoms went away within 24 hours, but it’s been almost 3 days since quitting, and my muscle pain and anxiety are still far worse than they were before taking Bactrim."

For Bacterial Skin Infection "I stepped on a rusty nail and had a lot of pain, and my foot started to swell. I started taking Bactrim, and the pain went away within the first two pills, which was 24 hours. The only problem is that I can't function with the nausea, dizziness, loss of appetite, and headache. I think it's because of a sensitive stomach."

For Urinary Tract Infection "I took Bactrim for 3 days for a urinary tract infection. I found relief only hours after taking the antibiotics but experienced severe nausea that continued to get worse no matter how much water I drank or how much I ate. Needless to say, I will be calling my family doctor to try something else."

For Urinary Tract Infection "This has been so scary. I went to doctors for a routine check-up, it turns out I have a UTI for which they prescribed Bactrim. Three days into the Bactrim, I was not feeling good-lightheaded, sick to my stomach, my head and face were burning up on fire, unbearable headache. Day 4, I ran a fever of 102.9 all day. Days 5 and 6 got worse, I couldn't even stand, couldn't sleep, the pain was unbearable from the tip of my head to the bottom of my feet. Day 7, I made it early in the morning to the doctors to see what was going on. Turns out (as the doc called it), a really drastic allergic reaction to this Bactrim. The doctor said, one more day and I would have ended up in the ICU. Today is day 8, and I'm still sitting here in excruciating pain. I called the doctor back and am waiting for an answer. I'm having trouble using my hands, and it's very painful to walk. So my suggestion is, if you feel ill after taking Bactrim, see your doctor soon."

For Urinary Tract Infection "Started taking Bactrim on a Saturday night for a UTI. I expected to feel better by the morning (I’ve had two other UTIs and I’ve felt better after the first pill). I woke up Sunday morning feeling almost exactly the same. I started to get the worst headaches of my life. Constant throbbing and feeling nauseous. My husband said just keep taking it and let the drugs run their course. Fast forward to Tuesday night, 7 pills in, I’m still feeling awful, still getting headaches. While reading reviews, I was shocked at all the horrible side effects. Like I said, I’ve taken two different antibiotics for two other UTIs and didn’t feel as awful as I did while taking Bactrim. I’m on a different antibiotic now, so we’ll see."

For Bacterial Skin Infection "Took Bactrim for folliculitis. First 7 days I only had vomiting and nausea, but on Day 8 I started getting fevers, intense shaking, throbbing headache, sweating, vomiting, insomnia, depression. I never felt this sick ever. It took me a while to realize it was the antibiotic. Once I stopped taking it, I broke out in a rash. Ended up having a sulfa allergy. Please be cautious when taking this. There was one point where I just wanted to call 911, I was in so much agony... It did help clear up much of the infection."

For Kidney Infections "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."

For Acne "I have been on Bactrim for a month now when nothing could clear up my acne. I tried everything, all the topicals and all the different antibiotics that are acne-specific, and nothing seemed to even touch my acne. So my dermatologist put me on this Bactrim, and it worked. In the month's time, my skin has cleared up, and if I do have a zit occasionally, it comes to a head super quick and heals quickly. My back and chest had tiny little zits over them, and now it’s nothing but smooth skin. Even my husband has said he notices that this is actually working. I didn’t really have any of the side effects, a little nausea and thirst the first week, but that was it, after that, nothing."

For Urinary Tract Infection "I took the first dose of Bactrim and developed a headache, which I treated with ibuprofen. I took pill #2 at bedtime. I woke during the night with an excruciating headache from my face to the back of my head. I made my way to the bathroom and took a couple more ibuprofen but had extreme nausea. The left side of my neck began to hurt and spread down to my upper back and shoulder. The pain was so severe I couldn’t stand to touch my neck or head. My temperature was 99.2 after taking ibuprofen. The pain began to let up the next day after stopping the Bactrim, but my abdomen became bloated and painful. Now, two weeks later, I’m still suffering with bloating, gas pain, rumbling, and discomfort. I texted my doctor and asked her to write in my chart that I will never take Bactrim again."

For Bacterial Skin Infection "Side effects: Extreme exhaustion, extreme irritability, inability to concentrate, nausea, itching and skin peeling at the site of finger infection, vaginal spotting, body aches, severe headaches. Rx was for 2 times a day for 10 days for severe infection on the end of the finger with red streaks. Completed medicine because infection was healing, but side effects were substantial!"

For Urinary Tract Infection "I get frequent urinary tract infections and was prescribed Bactrim by a doctor at an urgent care center because Macrobid made me pretty nauseous and really tired. It seemed to clear up the infection well but made me extremely sick. I vomited constantly while on Bactrim. I ended up missing four days of school before deciding I couldn't keep taking it and called urgent care for a new prescription. The doctor I talked to when I called said I should never have been prescribed Bactrim because people who don't tolerate Macrobid well usually have even worse side effects while on Bactrim. Since then, I have been prescribed Keflex when I get a UTI and have had no side effects at all."

For Urinary Tract Infection "Never again, first 10 days Macrobid. Still had infection. Put me on Bactrim. I was so sick after day 5. I missed 7 days of work, I think 10 days was too much. Had loose poop, nausea every day, dizzy, lost 7 lbs in 7 days, and the worst was the dry eyes and mouth. I felt like poo. I thought I would end up in the hospital. It even made me depressed! Never again!"

For Urinary Tract Infection "I mean a lot of people on here are saying it didn’t work, that’s probably because you have a different strain of bacteria from your UTI. It’s a guess-and-checking game until your urine culture comes back. Yep, every two months I get a freaking UTI. I have one now:)) and am on Bactrim. I think it’s my second time. The first time worked, now I think I have a different strain. If you don’t eat yogurt before you take it, prepare for extreme nausea and feeling like you’re on a horrible drug. Literally makes my eyes dilate. I feel high and nauseous. Taking a drug this strong, especially for a first guess diagnosis of strains, is so idiotic. Refuse if your doctor prescribes it as a first guess. Don’t put your body through that unnecessarily. Seriously."

For Urinary Tract Infection "Seemed to clear up my infection, but started feeling nauseous the next day. Steadily got worse each day. On the fourth day, developed a severe headache, but slept it off. Doctor instructed me to stop taking it. Experienced severely high blood pressure. Also made my abdominal muscles feel weak."

For Prostatitis "Bad side effects to the extent that I had to stop after 2 days. Flu-like symptoms, bad headache, pain in muscles and joints, low fever, no energy, could not eat, nausea - you name it, I had it. Too bad as I think it was starting to knock down my bacterial prostatitis. The flu-like symptoms were so convincing that I stopped for a few days, felt better, then started again just to make certain I didn't have the flu."

For Bronchitis "I took this medicine in early June for bronchitis. It worked, and I was all better by the time it was done. In early July, I began to feel general malaise with various symptoms, nausea, fatigue, etc. They did blood work and found that my AST and LST #'s were near 1000 and 900, respectively. It took 4 months for my numbers to go down. And a month later, I started to experience gastrointestinal problems, which is still going on. Not a good experience at all."

For Bacterial Infection "Was prescribed this almost 2 years ago for a skin infection but quit taking it after 3 days because of severe anxiety, indigestion, nausea, fatigue, dizziness, and who knows what else. At the time, I was dealing with panic attacks, so when my current doctor prescribed it last week, I decided, since I was feeling better, to give it one last effort. Days 1-2 were good. Skin was clearing, and other than being tired, I had no side effects. By day 3, I got a headache that was relentless, I was shaky, couldn't sleep at night but couldn't stay awake during the day, diarrhea started, and I quit the medicine at my doctor's advice. It's been over 48 hours since my last dose, and I still feel like crap. My neck hurts, and I'm still feeling incredibly anxious."

For Urinary Tract Infection "So I am on day 2 out of 5. First day was awful; 20 mins after my first dose, I started getting extremely itchy on my throat, neck, and face. My bottom lip flared up, and I got really nauseous. I turned the fan on, drank a bunch of water, and lied down. I was going to discontinue it, but after a good hour, all my symptoms went down. I decided to try it again this morning, and I'm feeling fine! Still a little burning when I urinate, but it is so much better now. Hoping this will work."

For Bacterial Skin Infection "I had an ingrown toenail, so my podiatrist removed it and put me on cephalexin for a week. After taking all of them, my toe was still infected. She put me on Bactrim to be taken twice a day for 10 days. Twenty-four hours after my first dose, my mood completely changed. I was depressed and miserable. Day 2, I was spinning, it was impossible to function for daily tasks, and I had no appetite. Day 3, I had a full-blown panic attack, then extreme anxiety, and following that, several heart palpitations. Day 6, I had a rash across my midsection. I stopped taking them that day and called my podiatrist, as my toe still wasn't getting better. She advised I stop and see her later on that day. She wound up removing another piece of nail that had been left behind. When I told her all of the symptoms, she said that I'm allergic. As a person who suffers from food allergies, this terrified me. After a week, the nausea, headache, and spinning started to lighten up, but it took around two months to get back to my normal routine. And to think... these symptoms are NORMAL for this medication."

For Urinary Tract Infection "I was prescribed Bactrim for a UTI, and after one dose, I immediately developed a splitting headache, followed later by weakness, body aches, chills, fever, slight nausea, cough, and sore throat. I feel as if I have the flu. I suppose the medication did do what it was supposed to do because the UTI feels as if it's almost completely gone (I'm sure it isn't, but at least it doesn't hurt). I will say I don't think the side effects are worth it. I'm in a lot of pain and discomfort, and I think I'll be going to the emergency room just to be on the safe side."

For Urinary Tract Infection "I had the worst experience with Bactrim. The first day, I had a 101.8 fever, chills, uncontrollable shaking, anxiety, rash, and fast heartbeat. The next day, I was extremely achy, nauseous, and could not eat anything the whole day. I stopped taking it after the second day, and my symptoms are getting better after a day, but I still feel cruddy and have a bad headache."

For Urinary Tract Infection "I was prescribed this medication for a UTI. After 1 pill, I woke up feeling nauseous, nonstop vomiting, bloating, diarrhea, headaches, insomnia, dizziness, weakness, loss of appetite, fever, chills. I am currently on day 3 and will not be taking this anymore. I have zero improvements, which is to be expected after only 3 days. I was told to take 2 pills daily for 10 days. I can’t take the extreme side effects, and I don’t see why a doctor would prescribe this, with this many horrible side effects. I thought I had a stomach bug or food poisoning until I decided to look up the side effects and realized it’s the medicine. My kind was 800/160MG TB. I don’t recommend."

For Bacterial Infection "I was prescribed a 10-day course of Bactrim as a preventative measure after an injury. My wound healed well and no major problems other than nausea until Day 9, when I broke out in a rash. Started on my arms, quickly spread to my trunk, legs, and face. The rash was painful, swollen, and hot to the touch. It felt similar to a bad sunburn. Started taking Benadryl every 4-6 hours until I could get to the doctor, where I got a steroid shot. So far, that seems to be helping a lot. The doctor says I am allergic to sulfa drugs and make sure never to take it again or it could be even worse next time."
