A physician prescribes a prescription for a non-controlled schedule prescription with “prn” refills. So, the prescription is valid for what period of time?

A prescription for a non-controlled schedule prescription with “prn” refills may only be refilled up to 1 year from the date the prescription was written.

This is a general guideline, and some states may have different regulations. It is always best to check with your local pharmacy board to confirm the specific rules in your state.

The term “prn” stands for “pro re nata,” which means “as needed.” A prescription with “prn” refills means that the prescriber has authorized the pharmacist to refill the prescription as needed, up to the maximum number of refills specified on the prescription.

However, there are some limitations on how many times a prescription with “prn” refills can be refilled. One of these limitations is that the prescription can only be refilled up to 1 year from the date it was written. This is because the prescriber needs to re-evaluate the patient's condition and make sure that the medication is still appropriate and necessary.
