This medication is used to treat an overactive bladder. By relaxing the muscles in the bladder, oxybutynin improves symptoms such as the inability to control urination (incontinence), feeling that one has to urinate (urgency), and having to go to the bathroom often (frequency). This medication belongs to the class of drugs known as antispasmodics.

This medication is not recommended for use in children younger than 5 years of age. Consult your doctor for more information.

Read the Patient Information Leaflet provided by your pharmacist before you start using oxybutynin and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist.

Apply one patch to your skin every 3 to 4 days, or use as directed by your doctor. Remove the old patch before applying the new one. Follow the dosing schedule carefully. Try to always change the patch on the same 2 days of the week to help you remember.

Do not open the sealed pouch container until you are ready to apply the patch. Open the pouch and remove the protective liner from the patch to expose the adhesive. Apply the patch to a clean, dry, smooth area of skin on your stomach area (abdomen), hips, or buttocks. Press firmly to be sure the patch stays on. Apply to an area of skin that is under clothing and protected from sunlight. Avoid applying the patch on your waistline, since tight clothing may rub the patch off, or on areas where sitting may loosen it. Do not apply the patch to areas of skin that are irritated, oily, or to where lotions or powders have been applied.

Contact with water (e.g., swimming, bathing) will not change the way the drug works. Avoid rubbing the patch area 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 it away where it cannot be accidentally worn or swallowed by others, especially a child or pet.

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.

The length of treatment is determined by your doctor who may suggest periodic trials off the medication to see if you still need to be using it.

Inform your doctor if your condition persists or worsens.

Skin redness/itching/irritation at the application site, dry mouth, drowsiness, dizziness, blurred vision, headache, weakness, nausea or constipation may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water or use a saliva substitute.

To prevent constipation, maintain a diet adequate in fiber, drink plenty of water, and exercise. If you become constipated, consult your pharmacist for help in choosing a laxative (e.g., stimulant-type with stool softener).
