Saphris (asenapine) is an antipsychotic medication. It works by changing the actions of chemicals in the brain.
Saphris sublingual tablets are used to treat schizophrenia in adults, and bipolar I disorder in adults and children who are at least 10 years old.
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).
Saphris may also be used for purposes not listed in this medication guide.

Asenapine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. 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.
