I took Myrbetriq for about the same amount of time with no results, so I stopped taking it. Later I found out that if you have bladder retention it should not be taken. I retained a great deal. That experience was several years ago. As a result, I no longer see that urologist, and have had a prostatectomy for prostate cancer, gleason 7, with a combined diverticulotomy. Now, I'm dealing with those side affects. To be honest, I have dealt with incontinence issues for some time which I have learned to manage without drugs. I'd rather wear protection of some kind without feeling light headed, dry mouth, etc. as well as being able to void. Drugs don't always work for everyone.
