Haloperidol Injections

Haloperidol injection (often known as Haldol injection) is used for the rapid control of severe psychotic disorders, agitation, acute schizophrenia, manic states, and delirium. It is one of the most trusted medications for managing mental health emergencies due to its quick onset and proven efficacy.

Yes! Haloperidol injection is commonly used in palliative care for managing symptoms like nausea, vomiting, delirium, restlessness, and agitation in terminally ill patients. Hospice teams favor haloperidol for its effectiveness and relatively quick action in easing distress.

A single haloperidol injection typically lasts 4–12 hours for immediate relief, while long-acting (depot) haloperidol injections—such as Haldol Decanoate—can last up to 4 weeks, providing ongoing mental health stability for chronic conditions.

Haldol injection (haloperidol) can cause sedation and drowsiness, which makes it especially useful for controlling agitation, severe mania, or delirium in emergency or palliative care settings.

Haloperidol injections are highly effective, providing rapid symptom relief for acute psychosis, aggressive outbursts, delirium, and severe agitation. Its quick onset (within 15–30 minutes) makes it indispensable in emergency psychiatric care and hospital settings.

Haloperidol works by blocking dopamine receptors in the brain—specifically D2 receptors—which helps to reduce hallucinations, delusions, and extreme agitation. This action calms overactive thoughts and behaviors linked to schizophrenia, mania, and similar disorders.

Haloperidol sedation refers to using the injection to quickly and safely calm severely agitated, aggressive, or delirious patients, especially in ER, psychiatric, or end-of-life/hospice settings.

Hospice uses haloperidol for its effectiveness against delirium, agitation, terminal restlessness, and intractable nausea or vomiting. It provides rapid comfort in palliative care, improving patients’ final days.

Contraindications for haloperidol injection include: Severe CNS depression Coma Parkinson’s disease Known allergy to haloperidol Patients with certain cardiac conditions or long QT syndrome

No, haloperidol is not a narcotic. It is a typical antipsychotic medication, not related to opioids or controlled substances. It does not cause addiction.
