How many refills are allowed for a prescription of a Schedule III drug?

A Schedule III controlled substance can have up to five refills authorized within a six-month period from the date the prescription was issued. This regulation is set forth by the Drug Enforcement Administration (DEA), which provides guidelines on the maximum number of refills for various schedules of controlled substances.

For Schedule III drugs, the law permits refilling the prescription as long as the total quantity does not exceed a 6-month supply from the date of the original prescription. Therefore, having five refills ensures that the patient has consistent access to their medication while also allowing for careful oversight and regulation of the drug's use.

This rule helps ensure patient safety and the appropriate management of medications that have potential for abuse or dependence, which is characteristic of Schedule III drugs. The other options do not align with the federal regulations in place for Schedule III substances.
