small yellow round tablet P on one side, 4 on other side

[momOFteens2]

Can Anyone help me to identify a pill that I found in my Teenage daughter's car??

It is small, round (Like the size and shape of an pencil eraser on the end of a pencil), edges a slightly beveled, the color is bright yellow (like a lemon)
On one side of the pill is the letter P
on the other side of the pill is the number 4
there are no other markings
the pill is not scored

If you can help me identify this pill, please respond.. you can email me at www.myspace.com/radrad_200 or just respond to this post here on the site.

I looked through the pill identifier, and also called a pharmacist, and still do not know what this pill is. I was told that it could possibly be a Dilotta (I'm sorry, I do not know how to spell that correctly)

PLEASE HELP?!
Thank you
