Final answer:
The prescription for a non-controlled substance with no refill instructions can be refilled as often as needed within one year from the date it is first filled.
Step-by-step explanation:
If a practitioner issues a prescription for a non-controlled substance with no instructions relating to any refills, then the pharmacy can refill the prescription as often as needed up to one year from the date of the original prescription is first filled. This guideline allows patients to continue their medication without having to visit the practitioner for a new prescription within the one-year framework. However, it's critical for patients to understand that pharmacies also follow state-specific regulations which may impact the exact refill rules. Always check with your pharmacist or healthcare provider for information pertinent to your situation and state laws.
