Sulfamethoxazole / trimethoprim for Bacterial Infection "I have been on Bactrim DS for 6 days (4 more to go) and was diagnosed with MRSA. I feel the medicine is working very well, but my side effects are bad! I feel nauseous all day. I have a hard time eating. I feel like I'm pregnant. My stomach cramps, sometimes bloated, a little bit of dizziness here and there, and always feeling like I am going to throw up. I'm just really glad that Bactrim DS is working for my MRSA because I really don't want to go through different meds and then end up being hospitalized because I couldn't find the right antibiotics for treatment."

Sulfamethoxazole / trimethoprim 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 Bacterial Infection "I have a lot of medical issues and take a lot of medications, and feel I have a stomach of steel because nothing really bothers me. Anyway, my doctor prescribed this antibiotic to me for a UTI...twice a day for 3 days. Doesn’t say the mg on the bottle, so I have no idea. Anyway, the first day I did okay, the second, not so much. I woke up feeling very antsy and anxious, like I needed my next “fix,” and I am one who has never smoked even a cigarette in my entire life, let alone any type of pot or illegal drugs to get high, so this feeling was very unsettling for me. My head hurt horribly and felt very fuzzy and dizzy. I was sure I must have contracted the Coronavirus, but no temperature and otherwise fine. I roughed it out the 3 days but felt like rubbish the whole time, only today, 5 days after my last dose, did I wake up without the fuzzy, needing my next fix feeling. I still have a headache, but thank God the other side effects are wearing off. I will never take this medication again :("

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I have been on Bactrim for 1 week now, and my skin is almost completely clear. I had a very bad infection across my chin and up to the right side of my nose, small red bumps, and an itchy rash that would peel over and got infected. Within 2 days, I noticed a huge difference. This medicine saved my life for sure. Dermatitis and skin issues on the face can really do a number on your self-esteem. I am back to almost clear skin and so, so happy. A little tired and was dizzy at first, but promethazine helps with that if your doctor can prescribe it, it helps with nausea. Other than that, this medicine rocks."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "Was prescribed Bactrim for UTI when first med did not work. 3rd day in, feeling better until 2nd dose taken. Began to feel nausea, dizzy, fatigue, terrible anxiety, unable to sleep or relax. Felt like I was going crazy. Also had constipation, back and stomach pain as well. Almost went to ER. This med is horrible. Never again!"

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I have been prescribed Bactrim for a skin infection in the form of 2 boils, 1 on my arm and 1 on my leg. I have been prescribed Bactrim 800/160 2x per day for 10 days. I started feeling horrible after the first dose. Extreme dizziness, stomach issues, headache by day 3, feeling dehydrated with weakness and joint pain and jaw pain, loss of appetite, insomnia. I am on day 5 and the dizziness is really bad, I had to miss work. I only took half a dose this morning and am considering stopping. Thinking I may be allergic to the sulfonamide as my grandmother is allergic, and this is the first time I have ever taken this. Glad to see others have had a good experience."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I'm on my fourth 800/160 pill of Bactrim, treating MRSA infection, which has also caused my lymph nodes behind my knee and groin to swell and hurt. I initially took doxycycline for about 4 days, with worsening infection. Bactrim worked day 1. The infection started to clear, and lymph swelling and pain are going away. Unfortunately, I had severe anxiety, including shaking, tightness in my chest, very dizzy, and feelings of doom. It's possible this was brought on by me overreacting to a slight side effect, but this is a very strong antibiotic. It works, but you might have to suffer through it. Not fun."

For Bacterial Infection "Prescribed sulfamethoxazole with trimethoprim for UTI, which it seems to have helped, but now I have painful sores all around my lips and some on the roof of my mouth. I seem to have an increase in anxiety and appear to myself dizziness, being off-balance and significant weight loss. So, I threw it out even though I've only taken it 3 full days, and I feel like I'm going to have a heart attack. Going into a doctor right now, but they can jump in the lake if they think I'm going to finish this...period. Horrible medication!"

For Urinary Tract Infection "Took this for a urinary tract infection, and I've had them before, taken other medicines. This appealed to me because it was a three-day deal. Started my first dose Thursday evening, and everything was going pretty smooth. I ended up having to leave work after two hours on Monday morning because my body was shaking uncontrollably (more hands than anything). I was nauseous, which I pretty much felt every day, but more so the last. And almost like my head was spinning, like I was going to faint. The shaking was the worst though."

Sulfamethoxazole / trimethoprim for Bacterial Infection "This medicine is working for me, but it makes me feel horrible. I've been shaking, have had a rapid heart rate, nausea, extremely thirsty, chills (no fever), dizziness, and cold hands and feet. I did find that taking probiotics helps. It doesn't take away everything, but it helps with the nausea. The only reason I continue to take it is because the doctor said this could be MRSA."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I was prescribed Bactrim DS for a paronychia infection on my right index finger. There was no apparent abscess, so the doctor felt a script of Bactrim DS would do the job. After taking the first pill, I began to feel dizzy and nauseous. Over the next few days, I had barely any appetite and wanted to sleep all day. I felt like I could not get enough sleep. I was also extremely sensitive to the sunlight, which only enhanced my desire to sleep more. Overall, the infection did not appear to change in the 3 1/2 days on the antibiotic, but that is not to say it did not work. I just was not able to function on it, therefore I called my doctor for something else."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I had an abscess that had been draining for about 6 days without end and finally went to the ER and had it lanced and packed. The ER doctor prescribed Bactrim DS. After two days, I became dizzy and nauseous and pretty much bedridden. Based on the reviews here and other sites, I have discontinued using the drug. (10-day dosage) The abscess has stopped draining and seems to be doing okay after taking the meds for 5 days. Also, the ER doctor failed to notice that my HBP med conflicts with this med. (Lisinopril) Next time, I will do more research. Normally, I do, but I felt so miserable, I assumed they knew better."

Sulfamethoxazole / trimethoprim for Bacterial Skin Infection "I found that within a day of taking Bactrim, the infection got better, which was GREAT because I had had it for a while. I experienced a few side effects: dizziness, lack of energy, insomnia if I took the pill a few hours before bed (I found to overcome this, I took the pill just before going to sleep), and headaches, but they seemed to dissipate after 2-3 days."

For Bacterial Infection "I had an abscess that popped, and I believe I got a staph infection. Day 1 on sulfamethoxazole with trimethoprim combo, I could tell the infection started healing overnight, felt a tad nauseous. Day 2, started feeling a little dizzy and more nausea. Now on day three, I puked all over the golf course trying to hit a couple of balls. Feel like complete crap. Head feels stuffy. Have no energy. Oh, and last night I had the craziest dreams I’ve ever had. I’m on track to losing my penis by day 10. Scared."

Sulfamethoxazole / trimethoprim 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!"

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I had a UTI, usually, it goes away with OTC Azo and water, but this time I could not get rid of it. So I went to the ER. They gave me Bactrim: 2 a day for 5 days. I took the entire round of them, and nothing changed. The medicine itself made me sick as a dog. I could eat with it or not eat with it, and it didn't matter. I was still so nauseous. It gave me chills and made me dizzy as well. I wouldn't give this to my worst enemy!"

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "Got a pretty nasty UTI... I've had them before, so I knew the drill. Went to the doctor. The infection was confirmed. He prescribed Bactrim DS, twice a day for 7 days. I read the information provided by the pharmacist, so I knew what to look for in case of a problem and took the first dose. I did have a few side effects: dizziness, mild nausea, and my blood sugar was off, but the infection felt better by the end of day 1. I can deal with mild side effects if it means fixing a larger problem. Pros and cons to everything! I would take it again if needed."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "Taking it now for a UTI. I was on Macrobid (nitrofurantoin) for a day or so first and woke up with chills, fever, and vomiting. Doc said she thought I was having a negative reaction to the med, so switched to Bactrim. This is working on the infection, but I've got extreme dizziness and fatigue as side effects. I have a history of having trouble with antibiotics, however--can't take penicillin or any of the cillins due to reacting with hives. Had a bad reaction to Doxycycline and/or Metronidazole last year (itchy 'bruises' formed on my limbs). Obviously, now nitrofurantoin is also off the menu. So I'm going with Bactrim because at least I'm not having flu-like symptoms with it. They say about one in 15 people has issues with antibiotics. I'm the one!"

Sulfamethoxazole / trimethoprim for Bacterial Infection "Was on the Bactrim antibiotic for 1 week to clear up epididymitis. It took around 4-5 days to notice any difference, and I didn't really experience any sort of side effects other than anxiety, which is something I already struggle with anyway, but it seemed to amplify it, and at times I felt confused and kind of dizzy. Make sure to drink lots of water, and also, I would recommend taking it with food to avoid any stomach problems. Overall, the pain from epididymitis is gone, and that is all I care about, I think the side effects are worth it, and remember they are only temporary."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "Knocked UTI symptoms out effectively after the first 24 hours. However, the side effects were not pleasant and were very noticeable: headache, nausea, dizziness, light-headedness, weakness, sweating, dry mouth, excessive thirst, tiredness. I'm on day 3 and have asked the doc to switch me to something else so I can function better at home and work. Trying Cipro. Be sure to drink water constantly when on Bactrim DS."

Sulfamethoxazole / trimethoprim 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."

Sulfamethoxazole / trimethoprim 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."

Sulfamethoxazole / trimethoprim for Sinusitis "Taking 2 pills twice a day every day. Something new for a side effect, great way to lose weight. Don't feel like eating at all, all I do is keep myself hydrated with fluids to thin the phlegm so I can cough it loose and get the rest out of my system. Can't wait till I can stop taking it. Also think it's shredding my red blood cells, feel tired and sometimes dizzy and weak."

Sulfamethoxazole / trimethoprim for Urinary Tract Infection "I took Bactrim 500 mg tablets twice a day for 4 days and felt fine. Day 5... not so much. I got extremely dizzy and super anxious about literally nothing. Don't tell my doctor, but I'm done taking them. Ha. Not really worth it. I only have 1.5 days left, so maybe I'll take it right before bed, but we'll see..... I'm not giving it one star because my symptoms did improve."

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."
