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.
GENERIC AVAILABLE: Yes
STORAGE: Tablets should be stored at room temperature, 15-30 C (59-86 F).
PRESCRIBED FOR: Haloperidol is used for treating schizophrenia, acute psychosis, and for tics and vocal utterances of Tourette's syndrome.
DRUG INTERACTIONS: Haloperidol causes sedation, and sedation may be greater if haloperidol is taken with alcohol and other drugs than can cause sedation such as the benzodiazepine class of anti-anxiety drugs for example:
The narcotic class of pain medications and its derivatives for example:
The tricyclic class of antidepressants for example:
Some antihistamines for example:
Certain antihypertensive medications for example:
Carbamazepine (Tegretol) may increase the elimination of haloperidol, rendering the haloperidol less effective. Rifampin (Rifadin) may decrease the elimination of haloperidol, increasing the risk of side effects from haloperidol.
PREGNANCY Neonates exposed to antipsychotics during the 3rd trimester may develop withdrawal symptoms and extrapyramidal symptoms.
