Urinary Tract Infection
"Am allergic to penicillin &amp; more recently Keflex -a not uncommon occurrence in those with penicillin allergy. Prior to allergy, Keflex was  slow to work &amp; caused nausea whether taken mid meal or on an empty stomach. I&#039;ve used Levaquin for stubborn sinus infections &amp; more recently my first UTI. The first time I took it, I experienced muscle soreness. With each subsequent prescription the side effects have vanished &amp; it&#039;s efficaciousness has not diminished .Of note for those who give up on it due to nausea &amp; muscle aches: hydration  helps reduce the symptoms. This med is not for those with certain heart issues or on some meds for mental health diagnosis."
