I found a pill that has L404 on it what is it?it is white and oval

A good reference is the Physician's Desk Reference (PDR).

Welcome to PDR.NET - The Physicians' Desk Reference web site providing prescription drug information and more

How did you find a pill, just walking down the street and said, look there is a pill, I will pick it up, and take it home and see what it is??

Come on, be honest, you are buying some pill from someone and want to see what it will do to you right??

We can not and should not help someone most likely use or buy illegal drugs

This is why I only answered one question about the name of a pill that was 'found". I told them to call poison control. LOL I was thinking the same thing you were.

You can go to Pill Identification Wizard - Drugs.com and use the pill identification wizard to help figure out what it is.

To the posters above refusing to give info, it's better to give the information then just act high and mighty about it... You might prevent someone from taking something with bad side effects.

Check the marking again, is it L484? This is a common marking for Acetaminophen (tylenol generic brands). Take a look at the link and check for yourself.
