Is it safe to take the drugs that have been kept in the drawer for a long time?
The expiration date of pills is two years, normally. Because a piece of pills has no expiration date written, you cannot know until when they are valid, if you throw away the package.
To supplement this shortcoming, a volatile special ink is applied to pill's corner where is easy to tear off, so a word, 'No' is exposed to the space that the ink disappears after the expiration date of two years and you can know if it is valid
d or not. Without the need of asking others, the pill package will answer you.
