These symptoms may include the inability to control urination (incontinence), feeling that one has to urinate (urgency), as well as having to go to the bathroom often (frequency).

How To Use

Use this medication exactly as prescribed. This medicine comes with a patient information leaflet. Ask your doctor, nurse, or pharmacist any questions you may have about this medicine. This medication is not recommended for use in children less than 5 years of age. Consult your doctor for more information. One patch is applied every 3 to 4 days and then replaced (i.e., the patch is changed twice a week); or use as directed by your doctor. 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 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 areas where lotions or powders have been applied. Contact with water when swimming, showering, bathing, or exercising will not change the way the drug 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 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. 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.
