Oxybutynin is a prescription drug approved by the Food and Drug Administration (FDA) to treat overactive bladder. Oxybutynin may be prescribed off-label to treat certain types of excessive sweating including generalized hyperhidrosis and cranio-facial hyperhidrosis in people who have not found relief from other treatments. Oxybutynin may be used on an as-needed basis to temporarily stop sweating during special events. Oxybutynin is available as a generic drug and also sold under brand name Ditropan.
Oxybutynin is an anticholinergic. Oxybutynin is believed to work by blocking chemical messengers that trigger the sweat glands to produce sweat.
