White Pill With M566

white oval pill with m 566 blank on other side

I know this pill is hydrocodone. What I'm trying to find is the milligram. It has an m566 on it and the other side is blank. ## @Jsnet, The oval white pill in question is actually combination of Acetaminophen (325mg) + Hydrocodone bitartrate (7.5 mg). For verification, the manufacturer is listed as Mallinckrodt and the pill itself carries a National Drug Code of 00406-0366. You can also view an image of the pill by clicking on the NDC link above. I hope this helps!
