Expiration Dates for Prescription Medicine: What You Need to Know
Understanding Expiration Dates for Prescription Medication
Drug expiration dates exist on most medication labels, including prescription, over-the-counter (OTC) and dietary (herbal) supplements. U.S. pharmaceutical manufacturers are required by law to place expiration dates on prescription products prior to marketing. These dates are a critical part of deciding if the product is safe and effective to use. But what do these dates really mean, and how long is a medication valid after its expiration date?The Importance of Expiration Dates
The U.S. Food and Drug Administration (FDA) began requiring an expiration date on prescription and over-the-counter medicines in 1979. This date reflects how long the manufacturer guarantees the safety and efficacy of the drug if stored properly. However, studies have shown that most drugs take a long time to degrade to a significant extent and are generally still 'good' long after the listed expiration date.Are Expired OTC Medications Safe to Take?
The vast majority of over-the-counter medications retain stability and potency well beyond the listed expiration date. When used for minor aches and pains or allergies, it is fine to use an over-the-counter medication that expired a couple of months ago until you can replace it. However, it's essential to note that medication expiration dates guarantee a drug's effectiveness and stability.Understanding the Expiration Date on Your Prescription
The expiration date on your prescription is a critical piece of information. It indicates the time period during which the product is known to remain stable, which means it retains its strength, quality, and purity when it is stored according to its instructions. If you notice that your prescription medication has expired, it's crucial to check the packaging for any signs of damage or tampering.What Happens if You Take an Expired Prescription Medication?
