Do not use a patch if the package is not sealed. Do not apply a patch that has been cut or damaged in any way. THE PATCH should be applied to a dry, smooth, undamaged, nonirradiated section of skin on a flat surface (eg, chest, back, flank, upper arm). In young children or patients with mental impairment, place the patch on their upper back to decrease the chance that they will remove the patch and put it in their mouths. Press firmly for 30 seconds to make sure the patch stays in place. Check to see that the edges of the patch are stuck to the skin. Wash your hands after applying or removing the patch. IF THE PATCH DOES NOT STICK, you may tape only the edges with first aid tape or cover the patch with a special type of clear adhesive film dressing (eg, Bioclusive, Tegaderm). Do not cover the patch with any other bandage or tape. Ask your doctor if you are unsure of what type of dressing you can use. A PATCH MAY BE WORN continuously for 72 hours or as directed by your doctor. If pain relief for more than 72 hours is needed, apply a new patch to a different skin area after removing the old patch. Do not wear more than 1 patch at a time unless your doctor tells you otherwise. If the patch falls off before 72 hours have passed, apply a new patch to a different skin site. PREVENT OTHERS FROM COMING INTO CONTACT with this medicine (eg, while hugging, sharing the same bed, accidental sitting on a patch, accidental exposure of a caregiver while applying or removing a patch).
