IMPORTANT WARNING: Return to top

[Posted 09/17/2007] Johnson and Johnson and FDA informed healthcare professionals that the WARNINGS section of the prescribing information for haloperidol has been revised to include a new Cardiovascular subsection regarding cases of sudden death, QT prolongation and Torsades de Pointes(TdP) in patients treated with haloperidol, especially when given intravenously, or at doses higher than recommended. Although injectable haloperidol is only approved by the FDA for intramuscular injection, there is considerable evidence that the intravenous administration of haloperidol is a relatively common off-label clinical practice.

There are at least 28 case reports of QT prolongation and TdP, some with fatal outcome in the context of off-label intravenous haloperidol. Healthcare professionals should consider this new risk information when making individual treatment decisions for their patients. For more information visit the FDA website at: http://www.fda.gov/medwatch/safety/2007/safety07.htm#Haloperidol and http://www.fda.gov/cder/drug/InfoSheets/HCP/haloperidol.htm.

Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.

Haloperidol is used to treat psychotic disorders and symptoms such as hallucinations, delusions, and hostility and to control muscular tics of the face, neck, hands, and shoulders. It is also used to treat severe behavioral problems in children and in hyperactive children (short-term use).

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used? Return to top

Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.

Haloperidol comes as a tablet and liquid concentrate to take by mouth. It usually is taken two or three times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take haloperidol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

The liquid concentrate must be diluted before use. It comes with a specially marked dropper for measuring the dose. Ask your pharmacist to show you how to use the dropper if you have difficulty. To dilute the liquid concentrate, add it to at least 2 ounces of milk, water, orange juice, or grapefruit juice just before you take it. If any beverage gets on the dropper, rinse the dropper with tap water before replacing it in the bottle. Do not allow the liquid concentrate to touch your skin or clothing; it can irritate your skin. If you spill the liquid concentrate on your skin, wash it off immediately with soap and water.

Continue to take haloperidol even if you feel well. Do not stop taking haloperidol without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will decrease your dose gradually. This drug must be taken regularly for a few weeks before its full effect is felt.
