Finding a random pill in your medicine cabinet and trying to identify it is a dubious undertaking.
First of all, there is no writing on the pill.
Second of all, THERE IS NO WRITING ON THE PILL!
How is a worried mom supposed to know what the pills are that she found in her teenage daughter’s room? How can you be sure it’s your morning pill or expired antibiotics?
There is a site, Pill Identifier, that proposes to help you figure out what pill it could be. But that’s just guesswork, because they don’t know what pill you have in your possession.
The bottom line is that without proper labeling, you just can’t be sure. If you don’t know what a pill is, don’t take it!
