Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I was diagnosed with a MRSA impetigo skin infection and was prescribed the Bactrim DS as well as Bactroban ointment, therefore, I cannot know which helped the most, but it did work 95%. I still have a pink area, and the original cut that started this all is still slightly visible. This oral med made me feel horrible. Every day, after the third day, I was nauseous about an hour after taking it, and several times had to take Zofran 8 mg, which did help. My stomach was a roller coaster, and the headaches were really bad. I have daily chronic headache, which is daily migraines. But I get C spine nerve ablations, which allows me to be 90% migraine-free for about 1 year. During the 10 days, the migraines came back and with a vengeance. Glad to be done."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "Not sure that the medication did much, as my abscess burst the night I started the antibiotics. All I know is that by the 3rd and 4th day of antibiotics, I was feeling generally unwell, had a headache, and awful nausea."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I'm currently taking Bactrim for a UTI. It relieved my symptoms rather quickly, however, the side effects are really bothering me. I've had the most painful migraines since taking it yesterday. I also have the chills and slight nausea. I won't take this medicine ever again once I finish it. The constant painful headaches are not worth it."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "This is day 2 taking this med. It makes me very queasy and very tired. The nausea and tiredness start about 30 minutes after I take one, and seem to last for 6 or 7 hours. I try to take it with food, but I don't have much appetite (not gonna be mad about that, tho). The UTI seems pretty much gone, but I'm also taking Azo."

Sulfamethoxazole / trimethoprim 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."

Sulfamethoxazole / trimethoprim 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."

Sulfamethoxazole / trimethoprim 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."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I have been having skin infections on my breasts off and on for 6 years. Ever since I developed mastitis when I was breastfeeding. I've been given Bactrim DS each time and advised to use Neosporin cream, not ointment. I'm not sure if it works all that great. It does take care of the red, rashy-looking inflammation surrounding the 'boil'/'blister', but does not seem to even really touch the actual blister itself. Without medication, it will take 3 - 4 weeks or so to heal, with meds it takes 2 weeks. I think it has a lot to do with the healing of the red rash part... so I continue to take it. The only side effect I have noticed is an almost unquenchable thirst. But no nausea, insomnia, or headaches for me."

For Sinusitis "I've had sinusitis for 9 months. Tried to treat it with natural remedies, but it finally affected my lungs, causing a severe chest infection. I've been taking trimethoprim 400 mg twice a day for 3 days, and I can say that I am feeling much better. No major side effects apart from nausea, but eating small amounts of food at regular intervals is helping. No upset stomach or stomach pains, which surprised me due to having IBS. Anyone suffering side effects, always remember that any antibiotic will cause you to feel unwell. You have to persevere with it, and they will ease. Failure to complete the course of medication will result in the infection coming back."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "Took 1 dose (first dose) at 6 am on a Tuesday. By 8 am, throat was sore. 9 am, feet went numb and started feeling odd, throat hurt more as well. By 11 am, feet were red and raw and hurt like nails poking through them. Genitals became beet red and raw! Had a fever and loss of appetite. Did not take any more after the first dose. Thursday, feet were better but still had a sore throat and genitals still raw and felt nauseous. Friday, still sore throat, genitals not as red or raw but developed a hive on them. It's now Saturday and still have a sore throat, color is back to normal on genitals but still have a hive and now another in the pubic hair area. I'm kinda freaking out now and probably go back to the doctor today. All this from one damn pill! UTI still there."

For Bacterial Skin Infection "I was prescribed a 10-day course for cellulitis, and after 5 days, the infection cleared. But I'm so nauseous, gassy, and dizzy I had to stop. I feel so bad I'm borderline suicidal. It's an effective drug for sure, but brutal on the GI tract. I pray this feeling goes away soon..."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I was prescribed this for a rather mild UTI. I took it with a granola bar in the morning and was drinking tons of water. Within 2 hours, the migraine set in, then the nausea and what felt like menstrual cramping, then the body aches and chills, and what I thought was a fever but was really just all my skin becoming very hot. My face looked like it had a slight sunburn. I called the pharmacy, and they said this was not the drug but rather symptoms of my UTI. I was so sick that I left work and went to urgent care, they retested my urine, which now came back negative for everything, and they told me to immediately discontinue taking it. The symptoms lasted well into the evening, and the migraine followed me into the following day. I'm not sure if this was an allergic reaction or if I was just super sensitive to it, but it was one of the worst nights of my life. For reference, I am 5'2, 120 lbs, and was given 160 mg twice daily for 3 days, and I do have a somewhat sensitive stomach."

Sulfamethoxazole / trimethoprim for Kidney Infections "I always get digestive issues (severe nausea, diarrhea, gas, upset stomach) from antibiotics. I hadn't taken Bactrim before. For me, the side effects have been very minimal. I eat a serving of carbs about 10 minutes before taking it (bread, pasta, or a banana) and then drink a large glass of water with it, and have made sure to drink a lot of water generally. I'm also taking a probiotic midday. The side effects I've had are being more tired than usual, low appetite, and a bit of a dull headache for a couple of days. After the initial dose, I had intense nausea, but I had not eaten. I have one day remaining of the 7-day course. After one day on Bactrim, my infection symptoms went away. I'll need a follow-up, but so far, yay Bactrim!!"

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I just took one 160 mg tab of Bactrim. This is the worst pill in history. I got a rash, headache, neck and back pain. Sore throat, bad. My whole body, muscles, and joints are in so much pain. Nausea. My husband has to get me food, put me in the tub to take a hot bath. I feel so weak, OMG. Fever of 101.5, which goes up and down still. Chills and lightheaded. The next day, I still have those symptoms. Gonna call my doc on Monday to give me a different pill. If there was a 0 rating, that's what I would give. Thought I was gonna die."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I have never had such a horrible experience with an antibiotic. I only took it for three days, twice a day, and I was so nauseous I couldn’t eat anything, and I got so dizzy that I couldn’t even walk straight. I will never take this antibiotic again."

Sulfamethoxazole / trimethoprim for Sinusitis "Took medication with the warning that it needed to be taken with 'plenty of water.' Woke up in the middle of the night with a severe headache and went back to sleep. Woke up in the morning for work and had debilitating nausea. I really hope this is just a temporary thing and I don't have to do this every time I take it."

For Bacterial Skin Infection "Worst medicine ever. I'm not allergic to anything, by the way. I was prescribed for a UTI and had to stop after 5 days. Migraines, eyeballs throbbed, chest was in excruciating pain, neck pain, upper and lower back pain, stomach and ovary pain, and leg pain, especially in the knees. On top of that, nausea, loss of appetite, dizziness, the immediate and random need to throw up, and worst of all, a red rash all over my body. To top that off, loss of sex drive. I have never had an allergic reaction to a medicine before. I will never take this again. BEWARE!!!!"

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "Today was the first day I took this medication. Two hours after, I experienced joint pain, blurred vision, back pain, a headache, chills, fever, nausea, cough, and sore throat. This was in addition to my already severe urinary tract infection symptoms, which I was sent to the ER for the night before, including severe pain in the pelvis, achy back (kidneys). Although symptoms of a severe UTI can also be fever, pain in the flank (pain that runs along the back at about waist level), chills, and nausea, I believe the medication gave me the additional symptoms. I was fine all day long until around two hours after taking the pill. After about 3 hours, symptoms increasingly went away. I am not sure if the pills are working or if they wore off."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "Was prescribed to take 2 pills a day for 5 days to clear a boil that hadn’t popped yet. Worst decision to take. After 1 pill, I had stomach cramps, nausea, diarrhea, and some jitters. I took the 2nd pill after consulting a family friend that is a doctor in another state, and the jitters got worse, my heart rate went up, and I woke up in the middle of the night having a panic attack. Consulted my family friend again (since couldn’t reach my doctor), and he agreed to stop the medicine since the side effects were worse than the potential benefit. Threw out the bottle and will be chatting with my doctor and maybe get a second opinion soon."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I’m a 20-year-old female with a history of gastrointestinal issues. I was worried about taking this drug because of all the negative reviews, but I had no problem with it. Took it for three days, experienced mild nausea and headaches, but my UTI symptoms were gone by day two. I also take 10 mg of amitriptyline daily and was worried about using them together, but the side effects didn’t disrupt my schedule at all. Every time I took a pill, I drank a whole bottle of water (16 oz) and ate a full meal. I think that is the most important part, because when I had a light meal, I did experience some stomach pain, but nothing severe. Also, I was very gassy, but that wasn’t really an issue, LOL. I’d recommend Bactrim."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I took one pill in the evening and another the following morning. I developed extreme stomach pain by noon, which moved to my back, followed by an excruciating headache. I was nauseous but sipped tiny amounts of water to prevent dehydration. I was very weak for two days, my hands trembled. Horrible experience."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "This is an awful medication, and I recommend it to anyone. Went to the ER for stomach pain to find out I had a bad UTI. Took 1 pill that the doc gave me and was completely fine. Took the next pill 12 hours later, with some saltine crackers and a bottle of water. 4 hours later, I was shaky, nauseated, thought I was going to throw up, my heart rate sped up, I had a fever (did go down with ibuprofen), had a minor rash on my cheeks, headache. Now marks 6 hours after taking it, laying down with a towel over my head, took Benadryl to help with the rash. Nausea has eased some, heating pad helps, the rash is not as red. Going back to the ER tomorrow for a different medicine. I'd rather take Amoxicillin, never have any reactions with that."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I had a bad UTI, and I have taken this in the past, and I am now taking it again. I get 4-7 days depending on the doctor. It almost always clears it up. If you don't eat like I do, then you can get nauseated if you take it on an empty stomach. The pill is huge, so I chew it and use a spoon of yogurt and eat it down like that. I wish they made chewable versions or coated versions, as it's hard to take, but I do take it! The pill is a miracle worker and helps me greatly."
