Haloperidol Decanoate IM

Uses
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.Haloperidol is also used for severe behavior problems in hyperactive children when other treatments or medications have not worked.
