What does the expiration date of a drug signify?

The expiration date of a drug signifies the date until which the manufacturer guarantees the full potency and safety of the medication. Beyond this date, the drug may begin to decline in effectiveness, and there could be potential safety risks associated with its use. This is essential for both healthcare professionals and patients, as using a medication that is past its expiration date may not provide the desired therapeutic effects and could pose health risks.

The designated expiration date is determined based on stability testing conducted by the manufacturer, which ensures that the drug maintains its intended quality when stored under recommended conditions. Therefore, it is crucial to adhere to this date for effective treatment.

Other aspects related to medications, such as the last date a drug can be prescribed, warranty periods, and effective marketing dates do not directly refer to the integrity of the drug’s quality as specified by the expiration date.
