What does the expiration date on medication signify?

The expiration date on a medication signifies the date until which the manufacturer guarantees that the medication will maintain its full potency and safety when stored under the recommended conditions. This date is determined through stability testing conducted by the manufacturer, which assesses how the medication retains its effectiveness and safety over time.

Using the medication beyond its expiration date may result in reduced efficacy and could pose risks regarding safety due to potential degradation. This is why it’s important to adhere to the expiration dates provided. Taking medications past this date doesn't automatically mean they are ineffective immediately after, but the manufacturer can't assure their safety and potency beyond that point.
