oxybutynin

An anticholinergic drug that relaxes the bladder muscle, used for overactive bladder.

What it means

A drug that calms bladder spasms, so the client feels the urge less often and leaks less. It comes as tablets, extended-release tablets, a skin patch and a gel. It has typical anticholinergic effects: dry mouth, constipation, blurred vision, trouble passing urine, less sweating and, in older adults, confusion.

For the nurse

Do not confuse its name with oxycodone. Teach the client to swallow XL tablets whole, avoid overheating, and report trouble passing urine. The Beers Criteria advise avoiding strong anticholinergics in older adults, especially with dementia.
