I take an anti-cholinergic for bladder function. Comes as a three day patch. One of it's side effects is that makes me more mobile. Noticeably. The urologist knew that it would have this effect, even though it nominally is designed to specifically target acetylcholine receptors in the bladder. There are a couple of other side-effects that are less welcome. One is increased apathy, and the other is falling asleep unexpectedly. If I forget to change the patch I lose both good and bad side effects

Other anticholinergics I have taken for the same problem have had similar effects, though this one takes the prize for both apathy and increased mobility. I am on my 4th drug of this type and my experience is that after some time they lose efficacy and I am back to square one with everything.... the oral ones had many more side-effects and I was happy to get off them......
