What is the maximum number of total refills for schedule III and IV controlled substances?

The correct answer is based on the regulations surrounding the refilling of controlled substances under federal law, which applies in Ohio. For Schedule III and IV substances, a prescription can be refilled a maximum of five times within six months from the date it was issued. Therefore, the total number of refills permissible is five, and the choice indicating a maximum of four is not consistent with this regulation.

Understanding the laws governing controlled substances is crucial in practice to ensure compliance and maintain proper medication management. This is particularly significant considering the potential for abuse and regulatory scrutiny surrounding these schedules. Thus, the option indicating a limit of four refills does not align with the established legal framework.
