Haloperidol decanoate, sold under the brand name Haldol Decanoate among others, is a typical antipsychotic which is used in the treatment of schizophrenia.[2][3][4][5] It is administered by injection into muscle at a dose of 100 to 200 mg once every 4 weeks or monthly.[6][7][8] The dorsogluteal site is recommended.[6] A 3.75-cm (1.5-inch), 21-gauge needle is generally used, but obese individuals may require a 6.5-cm (2.5-inch) needle to ensure that the drug is indeed injected intramuscularly and not subcutaneously.[6] Haloperidol decanoate is provided in the form of 50 or 100 mg/mL oil solution of sesame oil and benzyl alcohol in ampoules or pre-filled syringes.[6][7][9] Its elimination half-life after multiple doses is 21 days.[10][11] The medication is marketed in many countries throughout the world.[3][12]
