Haldol is available in sterile vials containing 5 mg strength Haldol per 1 ml of fluid used for injection. Usual starting dose is -5 mg intramuscularly. Dose may vary according to patient response to the drug. Switch to an oral form of this drug is recommended as soon as possible. Haldol may interact with other drugs so the patient needs close observation or monitoring to determine if other side effects develop. Haldol should only be used during pregnancy or in women likely to become pregnant only if the benefit clearly justifies a potential risk to the fetus; fetal abnormalities and fetal exposure to Haldol in the third trimester have shown dependence at birth. Women who are breastfeeding should not take Haldol because the drug may affect the infant. Although reports of use for behavior modification exist, the drug is not approved for use in children.
