Common use

Haloperidol is a first-generation (typical) antipsychotic medication belonging to the butyrophenone class, widely prescribed for the treatment of schizophrenia, acute psychotic episodes, and severe behavioral disturbances that do not respond to other interventions. It is also an established treatment for Tourette's syndrome, helping control motor and vocal tics, and is used to manage severe agitation, delirium, and acute aggression in both psychiatric and emergency settings. In some cases, haloperidol is prescribed for intractable nausea and vomiting, particularly when other antiemetic therapies have failed. The medication works by potently blocking dopamine D2 receptors in the mesolimbic and mesocortical pathways of the brain, effectively reducing psychotic symptoms such as hallucinations, delusions, disorganized thinking, and severe agitation. Haloperidol remains one of the most widely used and well-studied antipsychotic medications worldwide.

Dosage and direction

Haloperidol is available in multiple formulations: oral tablets, oral liquid concentrate, and injectable solutions (short-acting intramuscular and long-acting decanoate for maintenance therapy). The oral form is most commonly prescribed for outpatient use. Dosage varies significantly based on the patient's age, diagnosis, severity of symptoms, and individual response to treatment. For moderate symptoms, typical adult oral doses range from 1 to 6 mg daily divided into two or three doses; for severe psychosis, higher doses may be required under close medical supervision. Treatment is usually initiated at the lowest effective dose and gradually titrated upward. Follow your healthcare provider's specific instructions carefully, take the medication at the same times each day, and do not adjust the dose or discontinue treatment without medical supervision, as abrupt withdrawal can cause withdrawal symptoms and rebound psychosis.

Precautions

Before starting haloperidol, inform your doctor about all pre-existing medical conditions, especially heart problems (including QT interval prolongation, recent myocardial infarction, congestive heart failure, or history of arrhythmias), electrolyte imbalances (particularly low potassium or magnesium), seizure disorders, Parkinson's disease or parkinsonism, liver disease, thyroid disorders, pheochromocytoma, a history of depression or suicidal ideation, and prostatic hypertrophy or urinary retention. Haloperidol may cause significant drowsiness, dizziness, orthostatic hypotension, and extrapyramidal movement disorders. Avoid alcohol consumption entirely, as it potentiates central nervous system depression. Use extreme caution when driving or operating heavy machinery until you understand how the medication affects you. Elderly patients with dementia-related psychosis are at increased risk of death when treated with antipsychotic medications — haloperidol is not approved for this use. Prolonged use may lead to tardive dyskinesia, a potentially irreversible movement disorder.

Contraindications

Haloperidol is contraindicated in patients with severe central nervous system depression from any cause, comatose states, known hypersensitivity to haloperidol or other butyrophenone derivatives, and Parkinson's disease (unless the benefit clearly outweighs the substantial risk). It is also contraindicated in patients with known QT prolongation or congenital long QT syndrome, uncorrected hypokalemia or hypomagnesemia, and in patients taking other medications known to prolong the QT interval. Haloperidol should not be administered to patients with dementia-related behavioral disturbances due to an increased mortality risk.

Possible side effect

Common side effects of haloperidol include drowsiness, restlessness (akathisia), insomnia, dry mouth, blurred vision, constipation, weight gain, orthostatic hypotension, and extrapyramidal symptoms (muscle stiffness, tremors, involuntary movements). More serious adverse effects that require urgent medical intervention include tardive dyskinesia (involuntary repetitive movements of the face, tongue, or extremities), neuroleptic malignant syndrome (characterized by high fever, severe muscle rigidity, altered mental status, and autonomic instability — a life-threatening emergency), marked QT prolongation and potentially fatal cardiac arrhythmias (torsades de pointes), seizures, agranulocytosis, severe difficulty breathing, and severe allergic reactions. Seek immediate emergency medical attention if any of these serious symptoms occur.

Drug interaction

Haloperidol interacts with numerous medications. Significant interactions include antidepressants (especially tricyclics and SSRIs), antihistamines, anticholinergic medications, blood pressure medications (particularly those causing hypotension), antiepileptic drugs (carbamazepine, phenytoin may reduce haloperidol levels), sedatives and benzodiazepines, opioid analgesics, lithium, anticoagulants, and all drugs known to prolong the QT interval (certain antibiotics, antiarrhythmics, antifungals). CYP2D6 and CYP3A4 inhibitors (paroxetine, fluoxetine, ketoconazole) may increase haloperidol blood levels. Rifampicin and carbamazepine may decrease haloperidol levels. Inform your doctor about all medications, supplements, and herbal products you are taking to prevent potentially dangerous interactions.

Missed dose

If you miss a dose of haloperidol, take it as soon as you remember. However, if it is close to the time of your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take a double dose to compensate. If you frequently miss doses, discuss strategies with your healthcare provider, as consistent dosing is important for maintaining symptom control.

Overdose

Symptoms of haloperidol overdose may be severe and life-threatening, including profound drowsiness or sedation, dangerously low blood pressure, extreme muscle rigidity, generalized or focal tremors, life-threatening cardiac arrhythmias (QT prolongation, torsades de pointes), seizures, respiratory depression, and coma. Seek emergency medical assistance immediately if overdose is suspected. Treatment is supportive and may include cardiac monitoring, airway management, gastric lavage, and administration of activated charcoal if ingestion was recent. There is no specific antidote for haloperidol.

Storage

Store haloperidol tablets at room temperature between 15-30°C (59-86°F), protected from heat, moisture, and direct light. Keep in the original container with the lid tightly closed and out of reach of children and pets. Liquid formulations should be stored as directed on the label and protected from light. Do not use haloperidol after its expiration date.
