What must happen after a C11 medication is partially filled?

After a C11 medication is partially filled, the remaining quantity must be filled within 3 days. This requirement is rooted in federal regulations governing controlled substances. According to the Controlled Substances Act, when a prescription for a Schedule II medication is partially filled, the remaining supply can only be completed within a specific timeframe to ensure the medication's proper oversight and security.

Establishing a 3-day limit helps prevent misuse and ensures that the patient receives the full prescribed amount without unnecessary delays. This regulation is part of a broader effort to manage the distribution and usage of potentially addictive medications safely and responsibly. The correct answer reflects the importance of adhering to this timeline to maintain compliance with legal standards while serving the needs of patients.
