And just in case you're wondering about liquid/gel medicines, they are separate from the other liquid/gel baggie.
Also, if you're checking anything liquid or gel-ish...for instance I always check toothpaste b/c we use the non-fluoride kind and they just don't make small sizes of those...double-baggie it! You do NOT want a toothpaste (or hair gel or shampoo, etc) explosion in your checked bags, and it's possible while down in the luggage area.
