What is the maximum amount of other controlled substances that can be dispensed without a prescription?

The correct answer highlights an important regulation concerning the sale of certain over-the-counter (OTC) controlled substances. According to the federal regulations, specifically the Controlled Substances Act, there is a limit on the quantity of certain substances that can be purchased without a prescription. The limit for dispensing specific controlled substances without a prescription is set at no more than 4 ounces (which is equivalent to 120 milliliters) within a 48-hour period.

This regulation is crucial for controlling the potential misuse and abuse of these substances, which are often involved in substance dependence and addiction issues. Keeping the maximum amount at 4 ounces ensures that individuals cannot easily stockpile these drugs for non-medical use while still allowing for legitimate access to medication for conditions that can be treated with such substances.

Understanding this limitation helps pharmacists maintain compliance with legal guidelines while providing necessary care and medication to their patients.
