Which of the following is a recommended method for safe disposal of medications?

Mixing medication with cat litter or coffee grounds is a recommended method for safe disposal of medications because it helps to make the medication less recognizable and less appealing to anyone who might rummage through the trash, thereby reducing the risk of accidental ingestion or misuse. After mixing, the concoction should be placed in a sealed container or bag before being thrown in the household trash to ensure safety further. This method aligns with guidelines provided by various health organizations, emphasizing the importance of preventing diversion and minimizing environmental contamination.

The other disposal methods listed are not advisable. Returning medications to the place of purchase may not be permitted for all pharmacies, as many do not accept returns of medications once they have left the premises. Giving medications to a friend can lead to unsafe usage, as the friend may not have the appropriate medical knowledge to use them correctly. Pouring medications down the kitchen sink can contaminate water supplies and is harmful to the environment. Therefore, the method of mixing with cat litter or coffee grounds is recognized as a practical and safe practice for disposing of unused medications.
