urinary tract infection
"This medication definitely was effective in taking away the symptoms of urgency after I had a urinary procedure done. It worked pretty fast within 30min. However the side effect if "fluttering heart" was very negative for me as I have an anxiety disorder so the heart palpitations triggered me to get very panicky. The side effect starting after an hour of taking it and subsided about 2-3 hrs afterwards. Overall I would recommend this medication because the effectiveness was excellent."
