Sulfamethoxazole / trimethoprim
urinary tract infection
"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."
