I obviously cannot verify this for sure, but I can tell you that
Lortab Elixir (hydrocodone/acetaminophen) is yellow.
Tylenol with
Codeine elixir is orange.
Roxicet (oxycodone) elixir is red.
BTW, I'm an RN and we dispense these meds to patients who have surgery on their mouths/throats, and that is how I know the above. Obviously there isn't a way to know for sure, but the color CAN help. They all taste AWFUL, and not like OTC cough syrup.
