This medication is used to treat certain mental/mood disorders (such as schizophrenia, bipolar disorder). 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).

Take this medication as directed by your doctor, usually 2 times a day. Gently remove the medication from the packaging with dry hands by peeling back the tab. Do not push the tablet through the packaging. Place your dose of this medication under the tongue and allow it to dissolve completely in your saliva. Do not chew, crush, split, or swallow the tablet whole. Do not eat or drink anything for 10 minutes after taking this medication.
The dosage is based on your medical condition and response to treatment.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. It may take several weeks before you get the full benefit of this drug.
It is very important to continue taking this medication exactly as prescribed, even if you are feeling better and thinking more clearly. Do not increase your dose or take this drug more often than prescribed. Your condition will not improve any faster, and your risk of side effects will increase. Do not stop taking this medication without consulting your doctor.
Tell your doctor if your condition does not improve or if it worsens.
Drowsiness, dizziness, and weight gain may occur. Numbness/tingling of the mouth may also occur but usually goes away within 1 hour. Sores, blisters, or pain under the tongue may rarely occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
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 immediately 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.
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.
Infrequently, this medication may cause face/muscle twitching and uncontrollable movements (tardive dyskinesia). In some cases, this condition may be permanent. Tell your doctor immediately if you develop any uncontrollable movements such as lip smacking, mouth puckering, tongue thrusting, chewing, or unusual arm/leg movements.
This drug may infrequently make your blood sugar level rise, which can cause or worsen diabetes. Weight gain from this drug may increase the risk of this side effect. Tell your doctor immediately if you develop symptoms of high blood sugar such as increased thirst and urination. If you already have diabetes, be sure to check your blood sugars regularly. 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 immediately.
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: signs of infection (such as fever, persistent sore throat).
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, 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.

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.
