Pharmacy Inventory Management Notes

Importance of Inventory Management

  • Maintaining appropriate inventory is essential for the daily operations of a pharmacy.

  • Pharmacy technicians must understand all aspects of inventory control pertaining not just to medications but also to the necessary supplies (e.g., vials, needles, labels).

Issues with Inventory Levels

  • Too Much Inventory:

    • Increases the risk of medication expiration before use.

    • Potential for diversion of medications.

    • Capital is tied up in unsold inventory.

  • Too Little Inventory:

    • Can lead to delays in medication for patients.

    • Can result in partial fills of prescriptions which affects patient care.

Key Components of Inventory Process

  • Reorder Points (ROP): Minimum stock level at which a medication should be reordered.

  • Reorder Quantities (ROQ): Amount of medication to order once ROP is hit.

  • Computer software: Used to review trends, set ROP/ROQ automatically.

  • Shelf Organization:

    • Shelves must be clearly labeled with medication descriptions, order numbers, and ROP/ROQ

Responsibilities for Ordering Prescriptions

  • Review and edit computer-generated orders as needed.

  • Manually log items that need to be ordered.

  • Accurately fill out DEA222 order forms for all C2 substances, requiring signature from an authorized pharmacist.

    • Max of 10 different items per order form.

  • Visually inspect stock levels for fast movers and emergency medications.

  • Notify Pharmacist: If an item is backordered or discontinued and try to procure from alternate sources.

  • Print copies of submitted orders for tracking incoming stock.

Receiving Prescriptions: Procedures to Follow

  • Verify: Supplier name, address, and quantity against purchase order.

  • Inspect shipments for damage and take notes on observations.

  • Report any discrepancies to pharmacy buyer/manager.

  • Prioritize products needing extra care (e.g., temperature-sensitive, controlled substances).

  • Use PPE (Personal Protective Equipment) when handling medications.

Shipment Verification

  • Ensure that received shipments match the purchase order (NDC number, brand, quantity, strength).

  • Sign and date invoice to confirm receipt.

  • Check expiration dates to comply with pharmacy standards.

  • Report new, discontinued, or backordered products to management to avoid inventory shortages.

  • Timely stocking of received orders is crucial.

Stocking Process

  • Check expiration of new products against those in stock.

  • Implement First In, First Out (FIFO) method: Stock so that earlier expiration dates are dispensed first.

  • Inspect for unusual characteristics (e.g., broken seals or color changes) and report findings.

  • Communicate prescription patterns to purchasing team to avoid stock shortages.

  • Use ROP/ROQ as a guide while walking shelves for reorders.

Ongoing Inventory Management

  • Monitor expiration dates in addition to general ordering, receiving, and stocking.

  • Pull medications expiring within three months to prevent them from remaining on shelves.

  • Some medications can be returned post-expiration for credit; effectiveness and safety may decrease after expiration.

  • Institutional Settings: Monitor nursing units and automated dispensing systems for compliance.

  • Use color-coded stickers for signaling medications that are soon to expire.

  • Adjust ROP/ROQ as needed based on trends in expiration rates.

Special Considerations for Hazardous Medications

  • Maintain separate storage for hazardous drugs per USP Chapter 800 guidelines.

  • Label storage appropriately and ensure PPE is used when handling these medications.
