Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Apply the patch to clean, dry, and hairless skin on your stomach, hip, or the outer part of your upper arm. Press the patch firmly into place. You may leave the patch on while showering.
Remove the skin patch after 24 hours and replace it with a new one.
If a patch falls off, put on a new patch and leave it on only for the rest of your wearing time. Do not change your patch removal schedule.
Choose a different place on your body to wear the patch each time you put on a new one.
Do not wear more than one asenapine patch at a time. Never cut a skin patch.

What should I avoid while using asenapine transdermal?
Avoid sources of heat while wearing the patch. Do not use a heating pad or electric blanket, hair dryer, or heated waterbed. Heat can increase the amount of drug you absorb through your skin and may cause an overdose or death.
