Study Notes

Haldol Overview

Also known as Haloperidol, a prominent antipsychotic medication used for managing acute psychotic episodes.

Drug Class

Classified as a tranquilizer and an antipsychotic, it is primarily used to stabilize mental health conditions.

Mechanism of Action

Works by inhibiting central nervous system (CNS) catecholamine receptors, exhibiting strong anti-dopaminergic and weak anticholinergic properties.
Acts specifically on depress subcortical areas, the mid-brain, and the ascending reticular activating system, contributing to its calming effects.

Indications

Indicated for use in acute psychotic episodes, facilitating rapid intervention in severe mental health crises.

Contraindications

Not recommended for patients experiencing agitation due to shock or hypoxia and those with hypersensitivity to the drug.

Side Effects

Common side effects include extrapyramidal symptoms, restlessness, muscle spasms, Parkinson-like symptoms, drooling, dystonia, hypotension (both orthostatic and general), nausea, vomiting, and blurred vision.

Drug Interactions

Combining Haldol with alcohol may enhance CNS depression and hypotension.
It antagonizes the effects of amphetamines and epinephrine, while other CNS depressants can increase its sedative effects.

Dosage and Route

Adult dosage is 2-5 mg administered intramuscularly (IM) every 30-60 minutes until desired sedation is achieved.
Not recommended for pediatric patients.

Onset and Duration

The onset of action is approximately 10 minutes, with peak effects occurring between 30-45 minutes.
The duration of effects is variable, typically lasting from 12 to 24 hours.

Pregnancy Safety

Safety during pregnancy has not been established; caution is advised.

Special Considerations

For hypotension resulting from Haldol administration, treatment should include fluids and norepinephrine rather than epinephrine.
Patients on long-term therapy may be co-prescribed Cogentin (benztropine mesylate) to manage side effects related to extrapyramidal symptoms.
