The Food and Drug Administration (FDA) confirms expiration dates on over-the-counter (OTC) drugs. Factors like age and medication type influence the safety of using medication past its expiration date. Today is September 19, 2025.

Stability and Potency
The vast majority of over-the-counter medications retain stability and potency well beyond the listed expiration date. For minor aches, pains, or allergies, using an expired OTC medicine a couple of months past its date is generally acceptable until a replacement is obtained.
Safe Disposal
Proper disposal of unused or expired medicines, both prescription and OTC, is crucial. The best method is using a take-back option immediately. Avoid disposing of medicines in the bin or flushing them down the toilet. Instead, take them to a pharmacy for safe disposal. Keeping unused or expired medicines at home poses risks to families and pets.
Clinical Trials
Comparing a new product with a placebo can be the fastest and most reliable way to show the new products effectiveness.
Factors Affecting Medication Degradation
While many medications retain potency beyond their expiration date, several factors influence how quickly a drug degrades:
- Storage Conditions: Heat, light, and humidity can accelerate the breakdown of active ingredients. Medications stored in bathrooms or near windows are more likely to degrade faster.
- Formulation: Liquids and reconstituted medications (e.g., antibiotics mixed with water) tend to degrade more quickly than solid tablets or capsules.
- Active Ingredient: Some active ingredients are more stable than others.
Potential Risks of Using Expired Medication
While the risk is generally low, using expired medication can present some potential problems:
- Reduced Effectiveness: The drug may not be as potent as intended, potentially leading to inadequate treatment of the condition. This is particularly concerning for medications used to treat serious conditions like heart disease or infections.
- Chemical Changes: In rare cases, expired medications can undergo chemical changes that could be harmful. However, this is less common than a simple loss of potency.
- Antibiotic Resistance: Using expired antibiotics can contribute to antibiotic resistance if the dose is not sufficient to kill all bacteria, allowing the surviving bacteria to develop resistance.
When to Absolutely Avoid Expired Medication
Certain medications should never be used after their expiration date:
- Life-Saving Medications: Epinephrine (EpiPen), nitroglycerin (for chest pain), and insulin are crucial for managing life-threatening conditions. Using expired versions could have serious consequences.
- Liquid Medications: Due to their instability, liquid medications should be discarded after their expiration date.
- Eye Drops: Eye drops can become contaminated after opening, so it’s important to discard them after their expiration date to prevent infection.
Recommendations
Here are some general recommendations regarding expired medications:
- Check Expiration Dates Regularly: Periodically review your medicine cabinet and discard any expired medications.
- Store Medications Properly: Keep medications in a cool, dry place away from direct sunlight and humidity.
- When in Doubt, Throw it Out: If you are unsure about the safety or effectiveness of an expired medication, it’s best to discard it and obtain a new supply. Your health is worth the cost of replacement.
- Consult a Healthcare Professional: If you have questions about specific medications or their expiration dates, consult your doctor or pharmacist.
While many medications retain some potency beyond their expiration date, it’s crucial to be aware of the potential risks. Prioritizing safety by properly storing medications, regularly checking expiration dates, and discarding expired medications when in doubt is the best approach. For life-saving medications and certain formulations, adherence to expiration dates is paramount. Always consult a healthcare professional for personalized advice.
