Product details and regulatory record

How is it administered?

Dosage must be individualized, depending on the type and severity of the condition to be treated. It is preferable to give the drug when the stomach is empty. If taken soon after eating, nausea and vomiting may occur. The usual adult oral dosage is 10 to 50 mg, 3 to 4 times a day. The minimum effective dose is determined by giving 5 to 10 mg initially and repeating the same amount at hourly intervals until a satisfactory response occurs or a maximum of 50 mg has been given. The effects of the drug appear within 60 to 90 minutes and persist for up to 6 hours. Individual doses should therefore, be spaced at least 6 hours apart.

Included because it drives pack selection and wastage. Consult the monograph.
