Bactrim (sulfamethoxazole / trimethoprim): It's currently 12:30am, and I'm wide awake on a school night typing this. I didn't exactly have all the symptoms of a urinary tract infection, but always have the urgency to pee. I went to urgent care, and the doctor prescribed me Bactrim. I've been on it for 3 days (today will be my 4th), and I have yet to see results. According to some of you, it doesn't start working until the 5th day, which still gives me hope since the doctor told me it would work within 2 days. What I have been seeing is nausea, diarrhea, shakiness, insomnia, extreme headaches, and loss of appetite. I really hope this works. The constant urge to pee pretty much ruins what little social life I have. Having to make constant trips to the bathroom doesn't fit well with football games.

Bactrim DS (sulfamethoxazole / trimethoprim): I have reoccuring UTI's and have taken several different antibiotics for them. I was recently prescribed Bactrim DS. After taking the second pill, the aching, pain and soreness was almost gone. It works better for me than Cipro, but you should always have a urine culture to be sure which antibiotic is best for you. Fortunately, I haven't had any terrible side effects. The only side effect is feeling a bit fatiqued a few hours after taking Bactrim.

SMZ-TMP DS (sulfamethoxazole / trimethoprim): Based on results of a urine culture, I was put on this medication. I have taken 4 pills. While at work today, my tongue was feeling like I just took a big bite of piping hot pizza. The burning feeling was quite intense and I had not eaten anything that might have caused this. I also had numbness of my lips. The last pill I took was at 7:30 am and I still have intense burning and a bit of numbness. I was puzzled and decided to look up side effects of this new medication because it was the only thing newly exposed to my body. Since these problems were listed in your side effects listing, I will immediately discontinue using it.

Bactrim DS (sulfamethoxazole / trimethoprim): Worked after one dose. High dose of 3 strong pills once only. But today I feel lightheaded, dizzy and low appetite.

Bactrim (sulfamethoxazole / trimethoprim): I ended up with a urinary tract infection due to my diabetes. My PA prescribed Bactrim and I have not experienced any side effects. The burning and urge to urinate, but even after 2 days still feel like the bladder was not emptied. It is day 5 and I noticed some discoloration in urine in the morning hours. I take it that is due to some bleeding. It went back to clear yellow tonight. I am carefully completing the course of this medication and hope it works for others like it has for me. I feel great!

Cleared up the infection pretty fast but - 3rd day in and really faint, shakes and fast heart rate. Definitely not a good reaction to this.

Septra (sulfamethoxazole / trimethoprim): I've taken Septra DS before (with no side effects), but for some reason this time it is different! It has given me severe insomnia!! Very odd and super frustrating. Also has caused me a lot of nausea but doctor prescribed Zofran (also known as the miracle medicine for nausea), so that's better. Also feel a bit "out of it" and lethargic. One last strange symptom it's causing me is "urinary hesitancy." Had no idea there was such a thing until I spoke to my dr about it. Hoping these symptoms resolve or I may need to switch medicines, as only half way through this 10-day treatment.

I get UTI's all the time, they always give me this. Unfortunately with taking this medication I've gotten a lot of lower back pain, vomitting, and muscle weakness. It also takes a couple days for the pain to go away and the medicine to kick in. Thankfully, it clears up the UTI within 5/7 days.

Awful. Went to A E and was prescribed these. Ended up back in hospital a week later because these hadn't even touched me.

Bactrim (sulfamethoxazole / trimethoprim): 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

My baby is taking this from day of 4 after he was born. He always seems to be restless, uncomfortable, grunting sounds, spitting more than usual, motion problems, not constipated but difficulty in going poop, straining a lot.

Bactrim DS (sulfamethoxazole / trimethoprim): I used to get recurrent urinary tract infections but hadn't had one in 7 years. Just got one and they tried nitrofurantonin but it did nothing. I got Bactrim and the urgency and burning was gone within hours. I don't like taking antibiotics but UTIs are no joke. Bactrim worked for me and thank goodness. I get a little stomach ache but it beats the UTI symptoms!

Bactrim DS (sulfamethoxazole / trimethoprim): Felt mild relief, Doc said it should be gone in 3 days gave me enough to take it for 5 days in case it was not gone. I also experienced fevers and achiness. Not pleasant. Everyday I had discomfort and today I am out of it and feel terrible with my urinary tract symptoms again.

Bactrim (sulfamethoxazole / trimethoprim): 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.

I took this medicine after having many urinary tract infections in the past year. I usually am prescribed CIPRO but this time the nurse at the minute clinic CVS told me to try this. Little did I know how much worse I was going to feel. It did help with the UTI which then later became a yeast infection...but I became very weak, had a fever, no energy and went numb from my knees down my legs. I could not feel circulation in my legs.

Septra DS (sulfamethoxazole / trimethoprim): I tried taking Septra, and by the second day I was vomiting all day long. Couldn't take it long enough to cure the bladder infection and because of changing antibiotics partway through, ended up in a trip to the hospital with a kidney infection.

Bactrim (sulfamethoxazole / trimethoprim): I just started Bactrim. I have noticed a significant change for the better. For those of you that get yeast infections, eat lots of yogurt if you can. I have found this has helped me in the past.

After I got home and had taken about 4 of these I had loss of appetite, and had a headache. I looked at the papers from the pharmacy and I seen it said sulphamethazole! I called my doctor in a panic since it is listed in my allergies. I haven't had an allergic reaction, but my dad and moms side have. I finished out the antibiotic and have been fine. I did notice on Monday, which was my last dose, that I was feeling really queezy and had a headache. But no hives. Also This did some weird things while on it. I felt sick, and wasn't hungry, plus gave me a little anxiety. I will go back in a few days to make sure it is all cleared up. I took it for five days twice a day. I do however feel tons better.

Bactrim DS (sulfamethoxazole / trimethoprim): Make sure Bactrim is actually the correct medication for your UTI! I took Bactrim for 4 days with no relief before my doctor's office got the results back from my UA and realized that Bactrim is resistant to the bacteria causing my UTI. Now I am taking Cipro and it seems to be doing the trick. I did not have any side effects with Bactrim though, it just didn't work for me.

I took one for the first time for a urinary tract infection and about 3-4 hours after taking I had rapid heart beat, shaking, diarrhea and nausea. I took a Xanax because I mistook this for a panic attack but the Xanax did nothing to help and I started to get a strange flushing, burning skin sensation. The sensation happens in waves over my skin, very strange like nothing that has ever happened to me. Called Dr.s office and was told it was an allergic reaction, been taking Benadryl all day but still feeling the effects over 2 hours later!

Bactrim DS (sulfamethoxazole / trimethoprim): Bactrim did a great job! My whole lower part of the body hurt and burned, it was awful. I couldn't even walk for a while without feeling strong pain. Going to the toilet was a nightmare and it happened every five minutes. I took Bactrim and the symptoms got worse, but then in two days I was cured. no pain, no nothing. Bactrim is perfect.

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 Thurs evening and everything was going pretty smooth. I ended up having to leave work after two hrs on Monday morning because My body was shaking uncontrollably (more hands than anything). I was nauseous, which I pretty much felt everyday but more so the last. And almost like my head was spinning, like I was going to faint. The shaking was the worst though.

Bactrim (sulfamethoxazole / trimethoprim): Took Bactrim for 3 days. Cleared up the urinary tract infection but became very nauseous, weak, chills, sweats, no appetite and shaky. Still weak and somewhat nauseous after 3 days of not taking it.
