If you have leftover pet medications, dispose of them properly — and as soon as possible.

The best way to get rid of any medication is to deposit it at a drug take-back location. Many police departments now have drug disposal kiosks. Also, be on the lookout for the National Prescription Drug Take Back Day when additional sites are available.

If you can’t reach a drug take-back site, the disposal protocol depends on the medication. A few drugs can be flushed down the toilet — but only if they’re on the FDA flush list that can be accessed online. You should mix any other medications with an unappealing, inert substance, like coffee grounds, dirt or cat litter, seal it all in a container and place it in the trash.

One last thing: always cross out any personal information on packaging before it’s recycled.
