Answer below.: Is sunscreen from last year still good? When does sunscreen expire? Answers from Lawrence E. Gibson, M.D. Sunscreens are designed to remain at original strength for up to three years. This means that you can use leftover sunscreen from one year to the next. http://www.mayoclinic.org/healthy-living/adult-health/expert-answers/sunscreen-expire/faq-20057957

Medication expiry: Very difficult to say. Most medication expiry dates are conservatively estimated to allow for worst case scenarios. Depends a lot on how it was stored. If not exposed to high heat then may be OK, but it is a chemical compound that is subject to degradation. It would be OK to try, but do so under conservative conditions to see how it performs.
