Urinary tract infections (UTI) are more common in women than in men because women have shorter urethras that are closer to the genital tract. Ciprofloxacin is often used for treating UTIs. But large spectral antibiotics like ciprofloxacin can cause vaginal yeast infections in women. An acute vaginal yeast infection manifests with severe genital itching, painful urination and whitish vaginal discharge.


The brown discharge you notice might originate from the uterus and could be blood. Irregular bleeding from the uterus is a expected temporary side effect after coming off the birth control pills.
