Overactive bladder or urinary incontinence is a serious condition. It can disrupt even the most basic aspects of your daily life and cause embarrassing symptoms such as leaking or wetting accidents. Betmiga is a prescription medication that can resolve most cases of incontinence. You can buy it as a tablet in two doses - 25mg MR Modified Release (modified release), and 50mg MR - which should be taken daily. For those with kidney or liver impairment, the lower dose is recommended. To determine the root cause of your condition, you should consult your doctor.
