this stuff makes you wanna throw up or something gives you a bad feeling in your stomach for a few days till you get used to it. ive been on it before and its not as bad with the diarrhea as some antibotics are but it sure does make your tummy hurt. also experienced my mouth being really dry and stiffnes in my chest. overall not that bad tho and the symptons usually go away in a couple of days depending on how many your takin a day Published: February 22, 2008 ::

Within one day, I had horrible migraines, body aches, and nausea. I could barely get up. But it also took care of the UTI quickly, the pain in my lower stomach eased up. Published: December 15, 2007 ::

I hate this medicine. I had the worse allergic reaction to this, I was itching all over my skin felt like is was on fire. Then on top of that I had a fever of 103 and all I did was vomit. I didn't see any symptoms of a reaction until 2 days before I was done with the medicine. ...Good luck for other people who have to take this medicine. Published: January 22, 2009 ::

This med is working well for my UTI; however, I'm experiencing diarrhea and abdominal upset as well as heartburn as side effects. Eating yogurt and taking acidophilus supplements along with the drug is helping. Safe for nursing moms, which is a plus. Published: September 18, 2008 ::

Although this drug caused me to have great anal leakage, it cured me of my sinus infection. The anal leakage I experienced was often unpredictable and quite shocking. The pill itself is very large and difficult to swallow (I normally can swallow very LARGE things). It also caused me to have minor headaches. Overall Septra is extremely effective and works very fast. Published: December 11, 2008 ::

I went to ER for what turned out to be a UTI. Was prescribed a three day dose of this medication b/c I am breastfeeding a 6 month old and it's considered a safe drug that doesn't enter the milk ducts. After the first 12 hours on the medication, I was still in a good amount of pain. I didn't think the medication was working. I called ER to see if this was normal. I was told that it takes 12-24 hours to kick in and feel a difference. I am now on day three of the meds and the pain from the UTI has lessened but has not gone away. I foresee me going back to the doctor to be prescribed a different kind of medicine to knock the UTI infection out. Also while taking this medicine, my baby has been really fussy and crying a lot (she hardly ever fusses or crys). I would not recommend this antibiotic to anyone as it didn't work for me and didn't settle well with my baby. Published: March 28, 2008 ::
