FDA Rule on 28-Day Expiration Dating for Multi-Use Vials: What You Need to Know

Ever wondered how long a multi-use vial of medication can be used after it’s opened? Turns out, there’s a specific rule established by the Food and Drug Administration (FDA) to ensure patient safety and medication effectiveness.

What Do We Mean By Multi-Use Vials?

Multi-use vials are those that contain medication intended for multiple doses, often used in healthcare settings. Unlike single-use vials, these vials can be accessed several times, drawing out the needed amount of medication for each patient.

What’s the FDA Rule All About?

The FDA mandates that once opened, most multi-use vials should be discarded within 28 days. This is because entering the vial with a needle creates an opening for contamination by bacteria and other microorganisms. Over time, this can affect the drug’s potency and potentially harm patients.

However, there are some exceptions to this rule. Certain medications may have different expiry dates based on specific stability testing conducted by the manufacturer. These details will be clearly mentioned on the vial’s label.

The FDA established this rule to prioritize patient safety. Using expired medication can lead to:

Reduced effectiveness: Medication potency can decrease over time, making it less effective in treating the intended condition.

  • Increased risk of side effects: Degraded medication may contain impurities or contaminants that can cause adverse reactions.
  • Serious infections: Bacteria entering the vial can multiply and lead to serious infections if injected.

  • What You Can Do as a Patient

    Here’s what you can do as a patient to ensure safe medication usage:

    Always check the expiry date on the vial before using it.

  • If the vial has been opened, discard it within 28 days (or as specified by the manufacturer) regardless of the remaining medication.
  • Never use medication from a vial that has been opened by someone else.
  • Ask your healthcare provider if you have any questions or concerns about multi-use vials.
