I have two pills that I found in my husbands wash and I need to know what they are. One is a red and white capsule. On the red side it says pfizer and the white side it has PGN and under the PGN is a 75. What is this?

The second pill is a solid white pill. It has a score mark on it for breaking it in half and on one side N947 and an 800 on the other side? What is this?
Thank you for your help!

Call any pharmacy. They'll know

Look here for the first one : Pfizer | Pharmer.org -- Pill Identification Resources (http://www.pharmer.org/taxonomy/term/96)

Scroll down to the FOURTH description. That should be your pill.

Prescription Drug Information, Side Effects, Interactions - Drugs.com (http://www.drugs.com) Has a great pill identifier on it's site.

This one is your second pill
