Two weeks ago, Alan was prescriptive pills for her back pain, which is now getting better. He still has some pills left over from his prescription. What is the MOST appropriate action for Alan to take concerning these pills?

The most appropriate action for Alan to take concerning the leftover pills is to properly dispose of them. It is not safe to keep prescription medication once it is no longer needed, as it can lead to misuse or accidental ingestion by others. Alan can consult with a pharmacist or local health department for the proper way to dispose of the pills, such as through a drug take-back program or by mixing them with undesirable substances (like coffee grounds or cat litter) and throwing them in the trash.
