  • Haldol Injection Overview

    Haloperidol decanoate is used for long-term treatment of a certain mental/mood disorder (schizophrenia). It may be used in people who have trouble remembering to take medication every day. This medicine helps you to think more clearly, feel less nervous, and take part in everyday life. It can also prevent suicide in people who are likely to harm themselves. It also reduces aggression and the desire to hurt others. It can decrease negative thoughts and hallucinations. Haloperidol decanoate is a long-acting form of psychiatric medication (antipsychotic-type) that works by helping to restore the balance of certain natural substances (neurotransmitters) in the brain.

  • Haldol Injection Warnings

    There may be a slightly increased risk of serious, possibly fatal side effects (such as heart failure, fast/irregular heartbeat, pneumonia) when Haldol Injection is used by older adults with dementia. Haldol Injection is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of Haldol Injection, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.

  • How to Use Haldol Injection

    Most likely, you have used the form of haloperidol that is taken by mouth. Your doctor is using this form of haloperidol so that you won't have to remember to take Haldol Injection every day. Haldol Injection is the long-acting form of haloperidol. It is injected deep into a muscle (usually the buttocks) by a healthcare professional. Your first dose may be divided and given in separate injections given 3-7 days apart. After your doctor has found the best dose for you, Haldol Injection is usually given once every 3-4 weeks. Your Dosage of Haldol Injection is based on your condition and response to therapy. Haldol Injection takes a while to start working, so you will need to continue to take your other medication by mouth until your doctor tells you to stop. Haldol Injection must be used as prescribed. Do not suddenly stop using Haldol Injection without consulting your doctor. Some conditions may worsen if the medication is suddenly stopped. Inform your doctor if your symptoms do not improve or if they worsen.

Haloperidol decanoate 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.
