In medication labeling, which information is crucial for ensuring safety?

The expiration date is indeed a crucial piece of information for ensuring safety when it comes to medication labeling. This date indicates until when the medication is guaranteed to be effective and safe to use. After this date, the stability of the medication may deteriorate, potentially leading to reduced efficacy or harmful effects if consumed.

While pill color and manufacturer name provide important information, they do not directly relate to the safety and effectiveness of the medication in the way that the expiration date does. The pill color can assist in identifying the medication but does not inform the patient about the safety or efficacy of the drug after a certain period. Similarly, while knowing the manufacturer can be useful for validating the source of the medication, it is the expiration date that specifically informs the user about the drug's safe usage timeframe.
