For Urinary Tract Infection "I never had an allergic reaction until I took this medication, now I learned the hard way I'm allergic to sulfa drugs. After one dose I had a lot the serious side effects: high fever, intense stomach pain, insomnia, hallucinations, anxiety, non-stop chills/shaking, vomiting, rash. Needless to say I ended up in the hospital for 3 days. I think my that you need to be careful when taking the drug and be aware of all the serious side effects."

For Prostatitis "Bactrim almost finished me. Should have known as it wasn't working anyway and I was getting the DS prescription. Suddenly became very ill, needed to go to the hospital for IV fluids, had a terrible reaction , like the worst flu I ever experienced. 2 weeks later I am still getting ringing in my ears, and watching my skin carefully, fearfully as I broke out with nasty boils all over my arms and legs. If there is permanent damage I am considering the possibility of starting a lawsuit as my health seems to have been permanently damaged. I'd never been this sick with anything like this, and I am 68 years old, have always been in good health until now! I am very angry that a prescribed medication like this could be almost lethal to me."

For Urinary Tract Infection "I was prescribed Bactrim DS for a UTI. I drank a full glass of water with every dose and continued to drink large amounts of water throughout the day. I also made sure to take this on a full stomach. I’m a healthy 26 year old female and this is my first UTI. After taking Bactrim for 24hrs, I experienced severe side effects. I had debilitating kidney pain and lower back pain, severe gas, foamy explosive diarrhea, bloating, racing heart rate, severe anxiety (almost to the point of paranoia), and brain fog. I could not even hold a simple conversation. I felt like I was dying. After reading many reviews online, I discovered these same side effects have affected so many others while taking Bactrim. Once the drug was out of my system and I discontinued use, these side effects subsided. This antibiotic may work for some, but be aware of the possible severe side effects when you are assessing the risk of taking Bactrim."

For Bacterial Infection "This drug was almost the end of me. I had taken it several times before with no issues. However, this time I took three pills, and ended up in the hospital with Steven Johnson’s syndrome - which is serious severe reaction. It started with blisters covering the inside of my mouth. And then it spread all over my face and chest. I felt like I was literally ON FIRE!!! After very large doses of steroids and antihistamines, we were able to save my face. No scarring, thank God. But 2 months later, and I’m still struggling with the feeling of my face and chest getting really hot."

For Bacterial Skin Infection "I have just recently got out a living environment with a bunch of roomates, I found a small pimple under my arm and thought nothing of it, after a week it was so swollen and hot to touch I went to the ER. The doctor didn't want to cut the "pimple" open but I begged him to because of the pain-and he was glad he did...the amount of bacteria that came out was astonishing! He put me on bactrim and even though I had some side effects it went away.....but then I got another abcess on my head about 2 months later....took bactrim it went away....then 2 months after that i got another abcess on my finger....took bactrim it when away.....now i once again have 3 abscesses under my armpit and am currently on bactrim again! 4 months later!"

For Urinary Tract Infection "This is definitely my favourite medicine to treat urinary tract infections. I have a longstanding history with UTI's, one even sent me to the ER. The best part about this medicine is that it works quickly and feel relief within the first dose, which is great. I tried nitrofurantin once and absolutely hated it because of side effects & will stick with this. Luckily I've never experienced any negative side effects & I've taken with and without food. No nausea, nothing! It's definitely a hefty sized pill though."

For Bacterial Skin Infection "If you're ever on antibiotics, it's best to take a probiotic to help with stomach upset. However, I read you should take them as far away from your dose of antibiotic as possible. So, if you have to take it twice a day: take the Bactrim at breakfast and dinner. Then take the probiotics directly between at around lunch time. Taking any antibiotics with food also helps. Certain antibiotics have different food instructions so ask your pharmacist. I'm currently on Bactrim for a urinary tract infection, but I also have an infected hair that's been causing me a lot of pain in my groin so I'm hoping this will help there as well."

For Bacterial Skin Infection "I began getting serious boils in the worst places a man could ever get them. A nurse friend of mine knowing I was diabetic said that many diabetics get boils in the genital area and suggested I take Bactrim. This drug cleared them up quickly,leaving me to be one happy man."

For Urinary Tract Infection "I used to get UTIs every month or two until I finally started my daily dose of Raw Organic Apple Cider vinegar with “mother” mixed with honey water. It has been the only thing that has helped. I am now on my 8th month of no UTIs! It really surprised me as I’m not big into homeopathic remedies."

For Acne "I’ve been on Bactrim DS for 7 years. I’ll always stay on it, and I’ve had zero side effects. Just 75-95% clearer skin depending upon time of month. My blood work is perfect, I’m extremely fit, so there’s no reason you can’t stay on it for extended periods if it is a serious problem for you and you tolerate it well. I’d rather lose 5 years of life than go back to how I was. I get a special long term prescription and my life has been handed back to me after 15 years of Accutane, tetracyclines, and mycins. Nothing works like this. I’m not on birth control. It gives me the worst acne. This is what’s right for me. 10/10"

For Bacterial Skin Infection "I was prescribed Bactrim for 10 day course to treat Staph infection in my skin. I had no issues other than fatigue for first 6 days but by day 7 I woke up feeling dizzy and so tired. I kept pushing on taking the tablets because it was working to clear boils. By day 8-9 I had a rash over my body. I felt so lightheaded. Even laying down my body ached as if I had the flu."

For Acne "I have been on Bactrim Rx for about three weeks now and I already see a DRAMATIC improvement in my skin. All my cystic bumps are gone, haven’t had any active breakouts since the day I started it. My skin feels smooth and looks alive and glowing. My only problem was that it made me very nauseous (as most antibiotics do for me) so I would have to take it after I full meal. But I highly recommend talking to your dermatologist about this medication if you are tired of suffering and being depressed about your skin. It’ll be 100% worth it!"

For Acne "I am 52 with hormonal acne. My cysts were terrible. Did a number on my confidence. I have been on Bactrim for over a year for the cysts and finally something is working. I tried every other medicine with no results. Not sure how long I can be on this but I never want to stop. Afraid if I stop, the cysts will return."

For Bacterial Skin Infection "I took Bactrim for a bacterial infection under my skin, on my face, that resulted in many cystic like bumps. They were so painful. After taking the medicine for just a few days, the swelling and pain went away and the bumps cleared up. I would take this medicine again."

For Bacterial Skin Infection "I was first prescribed Augmentin for an infection from a puncture wound near the nail bed of my thumb. It made me feel like I was suffering from morning sickness and did not work. Next I got Flagyl and Bactrim. The culture showed the Staph was sensitive to Bactrim and the wound is SO much better! Yes, there are some side effects (for me, insomnia but I don't know if that is Flagyl or Bactrim) but it is so much better than losing my finger! I also took Florastor with the medication to reduce intestinal upset and experienced none."

For Acne "I hope this helps for anyone who is wanting to take Bactrim I got prescribed this by my dermatologist about a year and a half ago and it’s worked wonders! Everyone’s bodies react different to medications, but from my experience I can honestly say that It’s cleared up my acne completely and I had no side affects what so ever."

For Urinary Tract Infection "I was prescribed Bactrim and felt worse right away. After reading the side effects, I told myself that what I was feeling was normal. I took the prescribed dosage (2 per day) for 5 days, feeling even worst on the 5th day - shaky, diarrhea, headache, nervousness, unable to sleep. Then after some research, I discovered that there also were interaction side effects with my blood pressure medications. "

For Bacterial Skin Infection "I was prescribed Bactrim for a skin infection caused by an ingrown toenail. My podiatrist removed it, then put me on Bactrim DS (double strength) 2x daily for 2 weeks. After reading reviews here, I was terrified to take the first dose. I took it on an empty stomach because anxiety left me with no appetite. I drank plenty of water. Not one side effect. No nausea, no diarrhea, no insomnia, no sleepiness, no increased anxiety, no itchiness, nothing. The only thing was a mild headache on day two; however, I am prone to migraines so that could’ve been the norm with or without Bactrim. Some Excedrin worked, I haven’t had another headache since. I noticed my toe looking so much better with less pain by day 2 on Bactrim. I took one around 7 am, then a probiotic supplement around noon, followed by my second dose at 7 pm. People come here more when something goes wrong than when it works. That’s why I wanted to leave this review after a great experience."

For Acne "If you just started this medicine I know you're probably feeling bad about you acne. BUT LISTEN Bactrim works from the inside out and if you breakout in the first few weeks that's fine stick with it because soon your skin will be clear and Bactrim will help stop breakouts from ever happening in the first place soon! Cleared my hormonal acne. I rarely get a pimple and I had moderate to server acne and it was a life saver! Your acne will be cleared in just a few months. I suggest using a topical gel as well. Hang in there it helped me during a rough time in just 3 1/2 months I had a clear face, just a few acne marks on my cheeks only thing that stinks is I'm scared to go off the antibiotic and have a repulse of acne. But I suggest this!"

For Bacterial Infection "I am 30. I recently had a vasectomy which caused an infection while healing. Doctor prescribed Bactrim. I noticed after my nightly dosage, I would constantly wake up like I previously would when having an anxiety attack. I thought it was just due to outside stress but after reading this page I see it may have been increased by this medication. I wish I would have known sooner. Bactrim helped with my ailments but also made me use the last of my emergency Xanax in the process."

For Bacterial Skin Infection "I have severe medical anxiety thanks to terrible reactions to medications that started after a surgery. I’ve been on too many that made me feel absolutely crazy and had terrible side effects. I made the mistake of reading these reviews before starting Bactrim and was absolutely terrified. I took the first pill and immediately knew I was going to die and had terrible anxiety about this reaction I was going to have. But, guess what? I was FINE! I just took my last dose of a 7 day course and the only issue I had was making the mistake of going in the sun. I ended up burning a lot quicker than normal (there’s a warning for that). In fact, it had a pro to it… turns out it also helped my never ending stomach issues. Don’t let the other reviews scare you. As someone else said, most people only take the time to write reviews after a negative experience. That’s why I decided to start reviewing my positive ones."

For Bacterial Skin Infection "Was prescribed bactrim for a 'possible' infection in my leg from varicose veins. 2 pills a day for 10 days. Worst medication. Felt fine with the first pill, after the second pill I started to have bladder issues. Was peeing constantly, bladder felt heavy. Felt like I had to go after I just went. Was checked for a UTI, don't have one. Only took 2 pills and stopped. It has also caused headaches, my abdominal muscles feel weaker, loss of appetite. I must have been allergic or something.. Won't ever take this again."
