Foil wrappings and bags are designed to protect the contents it holds. Moisture is just one reason foil coverings are used to contain things. For medicine, it prevents oxygen or moisture from potentially cause the drug to change its chemical composition... If it was simply moisture and it was more than say five pills they were dispensing, they likely would place desiccant bags in the bottle. And if you leave chocolate exposed to air and moisture, it turns brittle or stale with time. They probably wrap it with foil to ensure the shelf life and quality of the product. The way things are packaged also might be government regulated.

Yes, it's to prevent either air or moisture from reaching the product.
Chocolate--especially milk chocolate --will get that white, dusty coating, called "bloom", if it's exposed to air. The bloom is harmless, but it looks unappealing. And if chocolate is exposed to moisture, it can cause the oils to separate out of the chocolate.
Medications contain very specific amounts of certain chemicals, designed to do a particular job (like cure your ear infection or unclog your arteries). Moisture, air, or even light can affect the chemicals in an adverse way, making the drug less effective, or even harmful. And most pills and tablets--not just medications, but nutritional supplements and other things--also contain starches, which help the pill keep it's shape. Moisture could cause the pills to disintegrate.

paper is semi-permeable meaning air and moisture can pass through.
Foil forms more of a barrier to air and moisture.
Foil keeps out air and moisture.
