After how many days from the expiration date must a drug be disposed of?

The correct choice is based on the regulations regarding pharmaceutical disposal practices in veterinary medicine in Arizona. When a drug expires, it is essential to ensure that it is no longer used to maintain the safety and efficacy of treatments. Disposing of expired drugs within 30 days from the expiration date is aligned with best practices established by regulatory bodies. This timeframe balances the necessity of ensuring that veterinary facilities do not have potentially unsafe medications on hand with providing a short window for facilities to properly manage their pharmaceutical inventory.

Disposing of drugs past this deadline may increase the risk of medication errors, contamination, or misuse, which is why a prompt disposal process is critical for maintaining professional standards and client trust in veterinary practices. Therefore, the 30-day rule is a widely accepted guideline for disposal practices in the veterinary field, making this the most appropriate answer.
