urinary tract infection
"I was prescribed this for a UTI. Took 1 dose (100 mg) in the morning as directed and within 4-6 hours was exhausted and lethargic. Later that night I was experiencing chills (woke up in a delirious fever like state), exhaustion, nausea (can't eat), severe joint pain everywhere (especially in my spine and knees), tightness in my lungs, I feel like crying because the the show must go on and I feel like I have the flu! I'm hoping by tomorrow (48 hours after 1 dose) I start to feel better. I've taken other antibiotics along with probiotics and never had a problem. This is an awful feeling!!! Seems like it works for others, but must not mix with my body chemistry, never again, would rather take penicillin and deal with getting hives again."
