Is medicine 2 years old still good?

The safety and efficacy of medicine that is two years old depend on the type of medication and its storage conditions. Many medications have expiration dates indicating when they may no longer be effective or safe to use. While some medications may still be effective beyond their expiration date, it's best to consult a pharmacist or healthcare provider before using any old medication. Always check for changes in appearance or smell, and when in doubt, it's safer to discard it.
