Asenapine Transdermal Patch

Use in older adults:

Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and that may cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as asenapine have an increased risk of death during treatment. Older adults with dementia may also have a greater chance of having a stroke or ministroke during treatment.

Asenapine transdermal patches are not approved by the Food and Drug Administration (FDA) for the treatment of behavioral problems in older adults with dementia. Talk to the doctor who prescribed this medication if you, a family member, or someone you care for has dementia and is using asenapine transdermal patches. For more information visit the FDA website: https://www.fda.gov/Drugs.

Talk to your doctor about the risk(s) of using asenapine transdermal patches.

Asenapine transdermal patches are used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Asenapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

Transdermal asenapine comes as a patch to apply to the skin. It is usually applied once a day. Apply the asenapine patch at around the same time each day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use the asenapine skin patch exactly as directed. Do not apply it more or less often than prescribed by your doctor.

Your doctor will probably start you on a low dose of asenapine and gradually increase your dose, not more often than once a week.

Transdermal asenapine may help to control your symptoms but will not cure your condition. Continue to use asenapine patches even if you feel well. Do not stop using asenapine patches without talking to your doctor.

Apply the patch to clean, dry, intact skin that is relatively free of hair (upper back, upper arm, abdomen [stomach area], or hip). Choose an area where the patch will not be rubbed by tight clothing. Do not apply the patch to an open wound or cut, to skin that is irritated, red, or to skin that is affected by a rash, burn, or other skin problem. Select a different area each day to avoid skin irritation. Be sure to remove the current patch before you apply a new one.

If your skin is irritated or burns after you apply an asenapine patch, remove the patch and apply a new patch to a different area.

After you apply an asenapine patch, you should wear it all the time until you are ready to remove it and put on a new patch. If the patch loosens before it is time to replace it, try to press it back in place with your fingers. If the patch cannot be pressed back on or falls off, dispose of it and apply a new patch to a different area. However, you should remove the new patch at the time that you were scheduled to remove the original patch.

While you are wearing an asenapine patch, protect the patch from direct heat such as heating pads, electric blankets, hair dryers, heat lamps, saunas, hot tubs, and heated water beds.You may shower while you are wearing an asenapine patch, but do not take a bath or go swimming.

To apply the patch, follow these steps:

1. Choose the area where you will apply the patch. Clean and dry the spot where you will apply the patch. Be sure the skin is free of powders, oil, and lotions.
2. Select a patch in a sealed pouch and cut the pouch open with scissors. Be careful not to cut the patch.
3. Remove the patch from the pouch and hold it with the protective liner facing you.
4. Peel the first piece of liner off one side of the patch. Be careful not to touch the sticky side with your fingers. A second strip of liner should remain stuck to the patch.
5. Press the patch firmly onto your skin with the sticky side down.
6. Remove the second strip of protective liner and press the rest of the sticky side of the patch firmly against your skin. Be sure that the patch is pressed flat against the skin with no bumps or folds and the edges are firmly attached to the skin.
7. Wash your hands with soap and water after you handle the patch.
8. After you have worn the patch for 24 hours, use your fingers to peel the patch off slowly and gently. Fold the patch in half with the sticky sides together and dispose of it safely, out of reach of children and pets.
9. Apply a new patch to a different area immediately by following steps 1 to 8.

If you become pregnant while using transdermal asenapine, call your doctor. Transdermal asenapine may cause problems in newborns following delivery if it is used during the last months of pregnancy.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are using transdermal asenapine.
• you should know that asenapine may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
• ask your doctor about the safe use of alcoholic beverages while you are using transdermal asenapine. Alcohol can make the side effects of asenapine worse.
• you should know that transdermal asenapine may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start using asenapine transdermal patches. To help avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
• you should know that asenapine may make it harder for your body to cool down when it gets very hot. While you are using transdermal asenapine, you should avoid excessive exercise, stay inside as much as possible and dress lightly in hot weather, stay out of the sun, and drink plenty of fluids.
• you should know that you may experience hyperglycemia (increase in your blood sugar) while you are using this medication, even if you do not already have diabetes. If you have schizophrenia, you are more likely to develop diabetes than people who do not have schizophrenia, and using transdermal asenapine or similar medications may increase this risk. Tell your doctor immediately if you have any of the following symptoms while you are using transdermal asenapine: extreme thirst, frequent urination, extreme hunger, blurred vision, or weakness. It is very important to call your doctor as soon as you have any of these symptoms, because high blood sugar can cause a serious condition called ketoacidosis. Ketoacidosis may become life-threatening if it is not treated at an early stage. Symptoms of ketoacidosis include dry mouth, nausea and vomiting, shortness of breath, breath that smells fruity, and decreased consciousness.

Unless your doctor tells you otherwise, continue your normal diet.

Apply the missed patch as soon as you remember it. However, you should still remove the patch at your regular patch removal time. If it is almost time for the next patch, skip the missed patch and continue your regular dosing schedule. Do not apply extra patches to make up for a missed dose.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Place the folded patch in the original pouch and dispose of it safely, out of the reach of children and pets.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily.
