Question

Are medical pill bottles (prescription med bottles) air-proof when shut?

Answer 1

No.  They are not air tight.  You can prove that by placing a sealed and empty bottle in a sink filled with water for a few minutes.  Then take it out and see the water inside the pill bottle

Answer 2

no

Answer 3

Yes, theya re water-proof therefore they are air-proof

Answer 4

The only ones that are air proof (to a degree) are the ones that have to be spun on.  The brown ones with the white tops usually are slide on and are not.  If you need a bottle to be, try buying some travel bottles made for liquids (shampoo, ect).

Answer 5

Maybe, but there would still be air inside of them when you shut it.

Answer 6

More or less. Plastic is not an air tight material per se, and oxygen actually penetrates plastic, but at a greatly decreased rate.

This helps increase the longevity of the material inside and the expiration date.
