Press firmly to be sure the patch will stay on. Usually, one patch is applied and replaced every 3 to 4 days (twice a week); or as directed by your doctor. Follow the dosing schedule carefully, always try to change the patch on the same 2 days of the week to help you remember. Apply the new patch to a different area of skin to prevent skin irritation. Do not apply a patch to the same area within 7 days. Apply to an area of skin that is under clothing and protected from sunlight.

Do not apply the patch to irritated, or oily skin or to areas where lotion or powder is applied. Contact with water when swimming, showering, bathing, or exercising will not change the way the medicine works. Try to avoid rubbing the patch though during these activities. If the area around the patch becomes red, itchy, or irritated, try a new site. If irritation continues or becomes worse, notify your doctor promptly. If the patch falls off, reapply it or apply a new patch and wear it until the next patch should be applied. When it is time to apply a new patch, remove the old one and dispose of it properly in the trash. Fold the sticky sides of the patch together and throw away where it cannot be accidentally worn or swallowed by another person, especially a child or pet.

Drug Class and Mechanism

Oxytrol has a dual mechanism of action. Contraction of the smooth muscle of the bladder is stimulated by the release of acetylcholine by the nerves within the bladder and the attachment of the acetylcholine to receptors on the surface of the muscle cells. Oxybutynin delivered into the blood suppresses involuntary contractions of the bladders smooth muscle (spasms) by blocking the release of acetylcholine. This is called an anticholinergic effect. Oxytrol also directly relaxes the bladders outer layer of muscle (the detrusor muscle).

Missed Dose

If you forget to change the patch on the day it is due, remove the old patch and apply a new one as soon as you remember and continue to follow your regular dosing schedule. Do not double the dose to catch up.
