im not an expert in this field, any information should be confirmed by a pharmacist or your physician. calling your pharmacy is a smart move. relying on my post is a dumb move... you may also seek clarification by posting at this site:
Prescription Drug Forum | Drugs.com
it is a forum site, like AMHD, but tied directly into helping people identify meds...
i believe the pink lortab is the same as the blue "lortab"... check the bottle of the blue for the name "lorcet"... its just another name, like lortab, for the hydrocodone/ acetaminophen combo... the 10 in both names should tie into the amount of hydrocodone... and the acetaminophen amount is likely 500mg... so same dosages, different manufacturer.
but... you MUST know this from a reliable source before taking it... especially since there is acetaminophen involved and this can lead to liver damage when dosages are exceeded.
