Haldol® (haloperidol) is an antipsychotic medication used for treating various conditions, including behavior problems, mental illnesses, and tics associated with Tourette syndrome. It is available by prescription and is approved for use in both adults and children.
There are several different forms of the drug, including oral solution, tablets, and injections. The oral forms of Haldol are typically taken two to three times a day, while the injectable forms are given either several times a day (for the short-acting injection) or just once a month (the long-acting injection).
Haldol belongs to a group of medications called "typical" or (first-generation) antipsychotic medications. It is not entirely known how the drug works. However, it is known that Haldol blocks or lessens the effects of dopamine, a chemical in the brain. Dopamine may be elevated in people with schizophrenia or other psychotic or behavior disorders.
Haldol is not a cure for schizophrenia or other psychotic or behavior disorders. It only helps to control symptoms (see Symptoms of Schizophrenia, Tourette Syndrome Symptoms, or ADHD Symptoms).
