From the Research
An expired 15 mg Adderall XR that is one year past its expiration date should not be taken, as the risk of decreased potency and potential harm due to chemical degradation outweighs any potential benefit, regardless of the estimated potency loss. Most medications, including Adderall (mixed amphetamine salts), don't suddenly become ineffective after their expiration date but rather gradually lose potency over time 1. However, the exact percentage of potency decrease is not well-established in the provided studies.
Key Considerations
- The expiration date on prescription medications is the manufacturer's guarantee of full potency and safety, and using expired medications, especially controlled substances like Adderall, carries risks 2.
- Expired medications may not only be less effective but could potentially be harmful due to chemical degradation 3.
- The degradation rate can vary based on storage conditions, with exposure to heat, light, and humidity accelerating the breakdown process 4.
Recommendation
- If you have an expired prescription, the appropriate action is to dispose of it properly and consult your healthcare provider for a new prescription if the medication is still needed for your treatment 5.
- It is essential to prioritize the safety and efficacy of medications, especially controlled substances like Adderall, and avoid using expired medications to minimize potential risks to morbidity, mortality, and quality of life.
