Detrusitol helps treat symptoms of an overactive bladder, such as not being able to hold urine, sudden urges to pee, or needing to pee often.
The usual dose is one 2 mg tablet, taken twice a day. If you have kidney or liver problems, or bothersome side effects, your doctor might lower your dose to one 1 mg tablet, twice a day.
Swallow the tablet whole with water.
Do not take more than 4 mg per day.
