The Pharmacist’s Take By · Clinical pharmacist · Written

Haloperidol is an older antipsychotic, available as a generic and around for decades, that treats schizophrenia and other psychotic disorders (plus Tourette’s Disorder for some products) by blocking dopamine. Newer antipsychotics are usually tried first, but it remains a familiar standby. It causes more movement side effects than most newer antipsychotics, such as stiffness, tremor, slowed movement and akathisia (an inner restlessness that makes sitting still hard). It carries a boxed warning for a higher risk of death in older adults with dementia-related psychosis, and it can cause serious heart rhythm problems. Report fever with severe stiffness, fainting, a racing heartbeat or new uncontrolled movements (possible tardive dyskinesia) promptly.

Clinical pearls

  • Haloperidol decanoate, the long-acting injection, is meant for people already stable on oral haloperidol and is given every 4 weeks.
  • Tell every prescriber you take it, since antibiotics like erythromycin or levofloxacin, plus methadone, can add to its heart rhythm risk.
  • Your prescriber may check an ECG (heart tracing) and potassium and magnesium levels, especially if you take a water pill or steroid.
  • If you also take lithium, report weakness, fever, tremor or confusion promptly, because the combination has caused a serious brain syndrome.

⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾

Older adults with dementia-related psychosis who take antipsychotics like haloperidol have a higher risk of death. In trials lasting about 10 weeks, about 4.5% of drug-treated patients died, compared with about 2.6% on placebo. Most deaths were heart-related (such as heart failure or sudden death) or infections (such as pneumonia). Haloperidol decanoate injection is not approved for dementia-related psychosis.

Patient information guide A plain-language walkthrough of Haloperidol, written from its FDA label.

What Haloperidol is used for

▾

Haloperidol is used for several conditions, depending on the product.

  • Schizophrenia: Haloperidol injection products, including Haloperidol Lactate.
  • Schizophrenia in adults previously stable on immediate-release oral haloperidol: Haldol Decanoate.
  • Schizophrenia needing prolonged injectable therapy: Haloperidol Decanoate.
  • Psychotic disorders: Haloperidol tablets and oral solution.
  • Tics and vocal utterances of Tourette’s Disorder: Haloperidol tablets and oral solution (children and adults), and one Haloperidol injection product.
  • Severe behavior problems and hyperactivity in children: Haloperidol tablets and oral solution, only after other treatments fail.

How Haloperidol works

▾

How haloperidol helps in schizophrenia is not fully understood. It may block dopamine type 2 receptors in the brain. It also binds more weakly to alpha-1 adrenergic receptors and barely binds to muscarinic or histamine (H1) receptors.

Haloperidol dosage

▾

Dosing is individualized and adjusted to your response.

  • Tablets and oral solution are taken by mouth, usually a few times daily.
  • Haldol Decanoate is injected deep into a muscle by a healthcare provider every 4 weeks. It is never given into a vein.
  • Haloperidol injection products are given into a muscle.

Follow your prescriber and the product label.

Dosing details from the FDA-approved label

From the Haloperidol prescribing information (“Dosage and Administration”). Doses are set by your prescriber for your product, condition, kidney function and age — never change a dose on your own.

  • Schizophrenic patients requiring prolonged parenteral antipsychotic therapy: initial conversion from oral haloperidol
    • Initial dose of haloperidol decanoate that is 10 to 20 times the previous daily dose in oral haloperidol equivalents, by deep intramuscular injection
    • Maximum: The initial dose should not exceed 100 mg regardless of previous antipsychotic dose requirements; if conversion requires more than 100 mg, give a maximum of 100 mg initially followed by the balance in 3 to 7 days
    • Maximum volume per injection site should not exceed 3 mL; do not administer intravenously
  • Patients who are elderly, debilitated, or stable on low doses of oral haloperidol (e.g. up to the equivalent of 10 mg/day oral haloperidol)
    • 10 to 15 times the previous daily dose in oral haloperidol equivalents for initial conversion (first month)
    • Maximum: The initial dose should not exceed 100 mg
    • Limited clinical experience suggests lower initial doses may be adequate
  • Patients previously maintained on higher doses of antipsychotics (risk of relapse) or tolerant to oral haloperidol
    • 20 times the previous daily dose in oral haloperidol equivalents should be considered for initial conversion, with downward titration on succeeding injections
    • Maximum: The initial dose should not exceed 100 mg
  • Maintenance therapy
    • Individualized with titration upward or downward based on therapeutic response
    • Usual maintenance range is 10 to 15 times the previous daily dose in oral haloperidol equivalents
    • Usually administered monthly or every 4 weeks
    • Maximum: Clinical experience at doses greater than 450 mg per month has been limited
    • Variation in patient response may require adjustment of the dosing interval as well as the dose
Read the label’s full dosing text

DOSAGE AND ADMINISTRATION There is considerable variation from patient to patient in the amount of medication required for treatment. As with all antipsychotic drugs, dosage should be individualized according to the needs and response of each patient. Dosage adjustments, either upward or downward, should be carried out as rapidly as practicable to achieve optimum therapeutic control. To determine the initial dosage, consideration should be given to the patient's age, severity of illness, previous response to other antipsychotic drugs, and any concomitant medication or disease state. Children, debilitated or geriatric patients, as well as those with a history of adverse reactions to antipsychotic drugs, may require less haloperidol. The optimal response in such patients is usually obtained with more gradual dosage adjustments and at lower dosage levels, as recommended below. Clinical experience suggests the following recommendations: Oral Administration Initial Dosage Range Adults Moderate Symptomatology - 0.5 mg to 2 mg b.i.d. or t.i.d. Severe Symptomatology - 3 mg to 5 mg b.i.d. or t.i.d. To achieve prompt control, higher doses may be required in some cases. Geriatric or Debilitated Patients - 0.5 mg to 2 mg b.i.d. or t.i.d. Chronic or Resistant Patients - 3 mg to 5 mg b.i.d. or t.i.d. Patients who remain severely disturbed or inadequately controlled may require dosage adjustment. Daily dosages up to 100 mg may be necessary in some cases to achieve an optimal response. Infrequently, haloperidol has been used in doses above 100 mg for severely resistant patients; however, the limited clinical usage has not demonstrated the safety of prolonged administration of such doses. Children The following recommendations apply to children between the ages of 3 and 12 years (weight range 15 kg to 40 kg). Haloperidol is not intended for children under 3 years old. Therapy should begin at the lowest dose possible (0.5 mg per day). If required, the dose should be increased by an increment of 0.5 mg at 5 to 7 day intervals until the desired therapeutic effect is obtained. (See chart below.) The total dose may be divided, to be given b.i.d. or t.i.d. Psychotic Disorders - 0.05 mg/kg/day to 0.15 mg/kg/day Nonpsychotic Behavior Disorders and Tourette's Disorder - 0.05 mg/kg/day to 0.075 mg/kg/day Severely disturbed psychotic children may require higher doses.

Haloperidol interactions

▾

Several medicines can change haloperidol’s effects.

  • QT-prolonging drugs (amiodarone, sotalol, citalopram, methadone, ziprasidone): higher risk of heart rhythm problems.
  • CYP3A4 or CYP2D6 inhibitors (ketoconazole, paroxetine, fluoxetine, ritonavir): raise haloperidol levels.
  • Carbamazepine, phenytoin, phenobarbital, rifampin, St John’s Wort: lower haloperidol levels.
  • Lithium: rare serious brain toxicity.
  • Alcohol, opioids, anesthetics: added sedation.
  • Levodopa: haloperidol may weaken its effect.

Not a complete list. The label covers the interactions the manufacturer studied or reported, and our own interaction database does not cover every medicine either. Bring your full medication list, including vitamins and herbal products, to your pharmacist.

Before taking Haloperidol

▾
  • Not for Parkinson’s disease, dementia with Lewy bodies, severe CNS depression or coma, or known allergy to haloperidol.
  • Tell your doctor about heart disease, long QT, electrolyte problems, thyroid problems, seizures, or low white blood cells.
  • Pregnancy: newborns exposed in the third trimester may have movement problems or withdrawal symptoms.
  • Breastfeeding: haloperidol passes into milk. Watch the baby for sleepiness and feeding problems.
  • Older adults and people with liver problems may need lower starting doses.
  • Haloperidol decanoate injection is not established for children.

Haloperidol overdose

▾

Overdose can cause severe muscle rigidity or tremor, very low blood pressure, heavy sedation, and even coma with slowed breathing. Heart rhythm changes are also possible. There is no specific antidote, and care is supportive. Call Poison Control at 1-800-222-1222.

What Haloperidol does in the body

▾

How haloperidol’s blood levels relate to its safety and effectiveness has not been fully characterized.

How your body processes Haloperidol

▾

After a haloperidol decanoate injection, blood levels peak at about 6 days. The half-life is about 3 weeks, and steady state takes 2 to 4 months of monthly injections. The liver breaks haloperidol down, mainly through glucuronidation and CYP3A4. Less than 3% leaves unchanged in urine. Levels may be higher in older adults and in people with liver problems.

How to store Haloperidol

▾

Dispense in a tight, light-resistant container as defined in the USP using a child-resistant closure. Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) Protect from light.

Haloperidol: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Haloperidol — the kind of thing our pharmacy team would talk through with you at the counter.

What is haloperidol for?

▾
It treats schizophrenia and other psychotic disorders. The tablets and oral solution are also used for Tourette’s tics and for certain severe behavior problems in children. Your product determines which of these applies.

How do I take it?

▾
Tablets and oral solution are taken by mouth as your prescriber directs. Injections are given into a muscle by a healthcare provider, and Haldol Decanoate is given every 4 weeks. Never change the schedule on your own.

What side effects should I expect?

▾
Movement-related effects are the most common, such as stiffness, tremor, restlessness, or slowed movement. Headache and stomach pain can also happen. Tell us about any new movements you can’t control.

When should I call my doctor right away?

▾
Call for fever with severe stiffness and confusion, fainting or a racing or irregular heartbeat, seizures, or swelling and trouble breathing. These can be serious.

Can I drink alcohol or take other medicines with it?

▾
Alcohol can add to sleepiness. Many medicines interact, including QT-prolonging drugs, lithium, and carbamazepine, so check with us before adding anything, including St John’s Wort.

Is it safe in pregnancy or for older adults?

▾
In late pregnancy it can cause movement or withdrawal symptoms in newborns, so talk with your doctor. Older adults with dementia-related psychosis have a higher risk of death, and older adults are more prone to tardive dyskinesia.

Is Haloperidol available over the counter?

▾
No. Haloperidol is a prescription medicine: every Haloperidol product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Haloperidol first available?

▾
The earliest FDA record we hold for Haloperidol is from 1986: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Haloperidol was first used.

Who makes Haloperidol?

▾
42 companies currently list Haloperidol products in the FDA's NDC Directory, including Bryant Ranch Prepack, Remedyrepack Inc., Method Pharmaceuticals, LLC. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

Haloperidol recall history

A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.

The FDA’s enforcement reports list 4 Haloperidol recalls since July 2021, covering 9 product listings. All of them are still ongoing or began in the last six months. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.
