This medication is used to treat certain mental/mood disorders (such as schizophrenia). Asenapine helps you to think more clearly, feel less nervous, and take part in everyday life. It may also help to decrease hallucinations (hearing/seeing things that are not there) and prevent severe mood swings. Asenapine is a psychiatric medication that belongs to the class of drugs called atypical antipsychotics. It works by helping to restore the balance of certain natural substances in the brain (neurotransmitters).
How to use Asenapine 3.8 Mg/24 Hour Transdermal 24 Patch
Read the Instructions for Use leaflet if available from your pharmacist before you start using asenapine patch and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
The asenapine patch is for use only on the skin. Apply the patch to the skin as directed by your doctor, usually once daily (every 24 hours). Remove the old patch first before applying a new patch. Do not wear 2 patches at the same time. To prevent skin irritation, change where you apply a new patch each time. When changing your patch, remove the old patch, fold it in half with the sticky sides together, and throw it away out of reach of children and pets.
Do not open the sealed pouch for the new patch until you are ready to use it. Open the pouch and remove the protective liner from the patch as directed. Do not cut the patch. Apply the patch as directed to a clean, dry, hairless area on the upper arm, upper back, abdomen, or hip. Do not apply the patch on skin that has cuts, scrapes, burns, rash, redness, or other skin problems. Do not apply the patch on skin that has lotions, oils, or powders on it. Avoid applying it to areas where tight clothing may rub the patch off. Wash your hands with soap and water after applying the patch. Do not wear the patch longer than 24 hours.
You may shower with the patch on. However, avoid bathing or swimming while wearing the patch, since these may cause the patch to fall off. Avoid heat sources (such as a hair dryer, heating pad, electric blanket, or heated water bed) at the application site.
Check the patch regularly during the day to make sure it is still firmly stuck to your skin, especially after showering, using the bathroom, changing clothes, sleeping, or sweating. If the patch edges lift off your skin, smooth them down and press them firmly back in place. If the patch falls off before it is due to be changed, apply a new patch right away. Replace the new patch at the regular time the next day. Do not try to reapply the old patch or use tape to keep a loose patch from falling off.
The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Use this medication regularly to get the most benefit from it. To help you remember, apply it at the same time each day.
It is very important to continue using this medication exactly as prescribed, even if you are feeling better and thinking more clearly. Do not increase your dose or use this drug more often than prescribed. Your condition will not improve any faster, and your risk of side effects will increase. Do not stop using this medication without consulting your doctor.
Tell your doctor if your condition does not get better or if it gets worse.
Redness, itching, pain, or irritation at the application site may occur. Drowsiness, dizziness, lightheadedness, or weight gain may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Dizziness and lightheadedness can increase the risk of falling. Get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
This drug may cause muscle/nervous system problems (extrapyramidal symptoms-EPS). Your doctor may prescribe another medication to decrease these side effects. Tell your doctor right away if you notice any of the following side effects: feelings of anxiety/agitation/jitteriness, drooling/trouble swallowing, restlessness/constant need to move, shaking (tremor), shuffling walk, stiff muscles, severe muscle spasms/cramping (such as twisting neck, arching back, eyes rolling up), mask-like expression of the face.
Infrequently, this medication may cause face/muscle twitching and uncontrollable movements (tardive dyskinesia). In some cases, this condition may be permanent. Tell your doctor right away if you develop any uncontrollable movements such as lip smacking, mouth puckering, tongue thrusting, chewing, or unusual arm/leg movements.
This drug may rarely make your blood sugar rise, which can cause or worsen diabetes. Weight gain from this drug may increase the risk of this side effect. Tell your doctor right away if you have symptoms of high blood sugar, such as increased thirst/urination. If you already have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.
In rare cases, asenapine may increase your level of a certain substance made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor right away.
Rarely, with similar drugs, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away, or permanent problems could occur.
Tell your doctor right away if you have any serious side effects, including: interrupted breathing during sleep (sleep apnea), signs of infection (such as sore throat that doesn't go away, fever, chills, cough).
This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness/pain/tenderness/weakness, severe tiredness, severe confusion, sweating, fast/irregular heartbeat, dark urine, signs of kidney problems (such as change in the amount of urine).
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Before using asenapine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using asenapine safely.
This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

When the weather is hot, drink a lot of fluids and dress lightly. If you overheat, quickly look for a place to cool down and rest. Get medical help right away if you have a fever that does not go away, mental/mood changes, headache, or dizziness.
Older adults may be more sensitive to the side effects of this drug, especially drowsiness, dizziness, lightheadedness, and QT prolongation (see above). Drowsiness, dizziness, and lightheadedness can increase the risk of falling.
During pregnancy, this medication should be used only when clearly needed. Babies born to mothers who have used this drug during the last 3 months of pregnancy may rarely develop symptoms including muscle stiffness or shakiness, drowsiness, feeding/breathing difficulties, or constant crying. If you notice any of these symptoms in your newborn especially during their first month, tell the doctor promptly.
Since untreated mental/mood problems (such as schizophrenia, bipolar disorder, depression) can be a serious condition, do not stop using this medication unless directed by your doctor.
