Hi Walter, I had my Radical Prostatectomy 13 months ago. I suffer from urinary incontinence and during the night I had to get up up to 7 times to urinate. My doctor prescribed Mirabegron for the OAB however it was not very helpful. I did some research on the internet and found a study done by doctors where they found that combining 50 mg of Mirabegron with 5 mg of Solifenacin (Vesicare in the USA)improve the OAB, I decided to try it and the results were very good. Reduced nightly trips to the bathroom to 1-2 times. During the day it also helps not to have emergencies.
I have attached a note that appears on the Medlineplus.gov website:
"Mirabegron is used alone or in combination with solifenacin (Vesicare) to treat overactive bladder (a condition in which the bladder muscles contract uncontrollably and cause frequent urination, urgent need to urinate, and inability to control urination) in adults. It is also used to treat neurogenic detrusor overactivity (a bladder control condition caused by brain, spinal cord or nerve problem) in children 3 years of age and older.Mirabegron is in a class of medications called beta-3 adrenergic agonists.It works by relaxing the bladder muscles to prevent urgent, frequent, or uncontrolled urination."
I hope help to you too.
