GENERIC NAME: haloperidol

BRAND NAME: Haldol

DRUG CLASS AND MECHANISM: Haloperidol is an antipsychotic medication. It also is used to control tics and vocal utterances that are part of Tourette's syndrome. Haloperidol interferes with the effects of neurotransmitters in the brain which are the chemical messengers that nerves manufacture and release to communicate with one another. Haloperidol blocks receptors for the neurotransmitters (specifically the dopamine and serotonin type 2 receptors) on the nerves. As a result, the nerves are not "activated" by the neurotransmitters released by other nerves. Haloperidol was approved by the FDA in 1967.

PRESCRIBED FOR: Haloperidol is used for treating schizophrenia, acute psychosis, and for tics and vocal utterances of Tourette's syndrome.
