What are the long term effects of taking 3-6mg robinul (glycopyrrolate) per day for hyperhidrosis? can this cause organ damage? if so what kind? how much is too much?

Unkown: Robinul (glycopyrrolate) is an anticholinergic drug so the side effects will include dry mouth, headaches, urinary retention, blurry vision and several others. The maximun dose should be 8 mg per day. There really are no long term effects except that the body adapts to the meds which will require you to keep taking higher doses. I would suggest a more permanent solution to your hyperhidrosis.
