Urinary Tract Infection
"I used to have recurrent UTIs (up to 10 a year), and usually I took ciprofloxacin, which almost always gave me yeast infections and an upset stomach. This medication takes longer to cure the UTI, but it hasn&#039;t given me side effects. 
Beware of what everyone says about lung failure though :/ I&#039;m taking a 100mg pill after sex nowadays, when I have more experience with it will share with you"
