Which drug products are exempt from expiration dates?

• A. Drugs with no dosage limit and are stable for 3 years (e.g., lotions, skin protectants)
• B. All OTC drugs
• C. Drugs with dosage limits
• D. Prescription drugs

Answer: (A)

Expiration dating exemptions apply to drug products that are proven to be stable for a long period and have no defined dosage limit. When a product meets these conditions, regulators allow skipping an expiration date because the product remains safe and effective for a stated stability window, typically three years, under proper storage. This is why certain stable topical products, like lotions and skin protectants, can be exempt: their use is generally generic, topical, and low-risk, and manufacturers can support a long shelf life with stability data, reducing the need for a printed expiration date.

Most OTC drugs, drugs with defined dosage limits, and prescription drugs normally carry expiration dating because their safety, potency, and dosing can depend on how they’re used, dispensed, or stored over time. The exemption is specific to products that meet the stability and dosage criteria and is not a blanket rule for all drug products.
