What is the maximum number of refills allowed for a prescription for Nuvigil?

The correct answer is that a prescription for Nuvigil, which contains the active ingredient armodafinil, can have a maximum of 5 refills or be filled within 6 months from the date it was issued. Nuvigil is classified as a Schedule IV controlled substance in the United States. This classification allows for refills under specific conditions.

Controlled substances are regulated by federal law, and different schedules have distinct rules regarding refills. For Schedule IV substances, a prescription can be refilled up to five times within six months. This is designed to provide flexibility for patients requiring ongoing therapy while maintaining appropriate control over the use of potentially addictive medications.

Other options, such as having no refills, only one refill, or extending refills up to one year, do not align with the established regulations for Schedule IV drugs like Nuvigil. Therefore, the option stating that Nuvigil can be refilled up to 5 times or within 6 months is accurate based on these pharmaceutical regulations.
