Mirabrone-50 is a medicine that helps you pee better if you have an overactive bladder. It relaxes the muscles in your bladder so you don’t feel like going to the bathroom all the time. You take one tablet a day, with or without food. Don’t crush or chew it, just swallow it whole. Mirabrone-50 may have some side effects, like high blood pressure, headache, or nausea. Talk to your doctor before taking it if you have any health problems or allergies.
