Handling a Controlled Substance Prescription — Practice Checklist

Step-by-Step Procedure (7 steps)

1. 1.

   Identify the DEA schedule of the medication (Schedule II through V) before processing — the schedule determines what's legally allowed.

2. 2.

   For Schedule II prescriptions: confirm there is no refill authorized (federal law prohibits refills on Schedule II — a new prescription is required every time) and verify the prescription meets any additional state-specific requirements (e.g., electronic prescribing mandates).

3. 3.

   For Schedule III and IV prescriptions: confirm the prescription has not exceeded 5 refills or 6 months from the date of issue, whichever comes first — after either limit, a new prescription is required.

4. 4.

   For Schedule V prescriptions: note that federal law does not cap the number of refills (refillable as authorized by the prescriber), though state law may impose stricter limits — check your state's rule.

5. 5.

   Verify the prescriber's DEA number is present and properly formatted on the prescription.

6. 6.

   Log the transaction per your pharmacy's controlled-substance recordkeeping procedure (perpetual inventory, biennial inventory requirements, etc., depending on schedule).

7. 7.

   If anything about the prescription looks altered, inconsistent, or otherwise suspicious, stop and involve the pharmacist before proceeding.

Quality Checkpoints (4)

Confirm each of these before considering the task complete.

• Schedule II prescriptions are never refilled — each fill requires a new, separate prescription.

• Schedule III/IV refill count and 6-month window are checked before authorizing a refill.

• DEA number format and prescriber credentials are verified, not assumed.

• Any sign of alteration or irregularity is escalated to the pharmacist immediately, not resolved independently.

Avoid These Mistakes

• ⚠

  Treating Schedule III/IV like non-controlled drugs and losing track of the 5-refill/6-month federal cap.

• ⚠

  Assuming Schedule V has the same unlimited-refill rule in every state — state law can be stricter than the federal floor.

• ⚠

  Processing a refill request on a Schedule II prescription because "it's basically the same as last time" — this is a hard federal rule, not a judgment call.

• ⚠

  Not double-checking a DEA number format when something about the handwriting or printout looks off.
