Where do Medicines and tablets go?

Pharmacies accept unwanted and expired medicines from the public and pass them to licensed incineration, which is the only route that reliably destroys the active ingredient. Binned medicine is accessible to children, pets and anyone going through the bin, and flushed medicine passes through sewage treatment largely intact and turns up in rivers. The FDA maintains a short flush list of drugs — mostly opioids such as fentanyl patches and oxycodone — where the risk of a child or pet finding a discarded dose outweighs the environmental cost, and those are the exception rather than the rule. Where no take-back exists locally, the FDA fallback is to mix tablets with coffee grounds or cat litter in a sealed bag before binning, but a pharmacy is better wherever one is reachable.

How to prepare it

1. Leave tablets in their blister or bottle; scratch your name off the label.
2. Take liquids in their original container with the cap on.
3. Ask the pharmacist rather than leaving anything on the counter.

What not to do

• Never flush medicines unless they are on the FDA flush list — sewage treatment does not remove most drug residues.
• Never bin loose tablets; a child or a dog finds them.
• Never pass leftover prescription medicine to someone else.
