Sulfamethoxazole / trimethoprim
"I was prescribed this after going to get a checkup because I knew something was off, but I had no UTI symptoms.  I have just spent the last 24 hours shaking, with tremendous headache, nauseated, chilled, and with insomnia. I would not recommend this medicine to a sensitive female.  I cried until 2 am, and finally fell asleep.  I have abdomen pain bloating which was not there before, and it feels like a yeast infection is festering.  



I am going to go back to my cranberry, water, and oregano oil methods.  I also read about d-mannose but that looks more preventative.  Probiotic too."
