Short answer

**Asenapine transdermal patches can cause skin irritation, weight gain, sleepiness, dizziness, restlessness, and muscle stiffness or tremor.**

Your risk depends on your dose, other medicines, and health conditions. Your blood sugar and cholesterol can rise, so your prescriber should monitor these along with your weight. Rotate application sites daily and keep heating pads and other direct heat away from your patch because heat increases drug absorption. If you are an older adult with dementia-related psychosis, discuss the increased risk of death with your prescriber; this patch is not approved for that use.
