Pill Identification Wizard (http://www.drugs.com/imprints.php?action=search&drugname=&imprint=v+2103&shape=&color=2&I1=Search)

The best thing to do, is to take it to a pharmacist who can visit with you and also see the pill in person.

The site referenced above is good, but not foolproof. But, it's certainly better to use a site that is specifically designed for the identification of pills rather than people who are strangers to you and not pharmacists. Please see an example of discrepancies in the identification of a pill on the following link. The thread there is two pages in length.

Amitryptiline, it's an anti-depressant drug traditionally. :)
