What is the standard time limit for filling a partial fill of a CII prescription after it is written?

The standard time limit for filling a partial fill of a Schedule II (CII) prescription is 30 days from the date the prescription was written. This rule allows patients to receive their medication incrementally instead of all at once, which can be helpful in managing dosages or addressing concerns about the quantity of controlled substances being dispensed.

Under the Controlled Substances Act, a partial fill is permissible for CII medications as long as the full quantity prescribed is dispensed within this 30-day period, and the patient has the right to request the remaining portion. It's important to note that once this 30-day period expires, any remaining refills or partial fills are void, and a new prescription must be issued by the prescriber.

Contextually, other time limits provided in the choices exceed the regulatory framework for CII prescriptions. For instance, 60 days or 90 days would not align with federal guidelines, which maintain stricter controls on the dispensing of CII medications to minimize risks associated with misuse or diversion.
