Is there a maximum number of refills for prescriptions for legend drugs?

The correct understanding regarding refills for prescriptions for legend drugs is that, under federal law, they are valid for one year from the date of issuance. This means that while there is no maximum number of refills specified (up to a total of one year's validity), the prescribing physician must indicate the number of refills when they write the prescription. If the prescriber does not specify any refills or specifies a specific number less than the maximum allowed by law, then those terms apply.

The provision allows for flexibility in managing ongoing therapies, as patients may need to obtain their medication multiple times without needing a new prescription every time, as long as it is within the one-year period.

The other responses either inaccurately limit the number of refills or misrepresent the validity regulation, which does not focus solely on refill numbers but rather on the overall one-year time frame within which refills can be filled according to the original prescription.
