Final answer:
C-III or C-IV prescriptions can be refilled up to five times and expire after six months, requiring a new prescription for further medication.
Step-by-step explanation:
C-III (Schedule III) or C-IV (Schedule IV) prescription orders may only be refilled up to five times within a six-month period and expire after that duration. If the patient needs more medication after the refills or the six months are finished, a new prescription from a healthcare provider is required. Schedule III and IV drugs have a lower potential for abuse compared to Schedule I and II drugs, but still require careful monitoring.
