Is there codeine in hydrocodone or demoral or dylaudid none

That . That is a very good question. All of these medications are "synthetic" opioids. There is no Codeine in hydrocodone, demerol, (meperidine hydrochloride) or dilaudid. However, some people who are allergic to one can be allergic to another synthetic opioid.
Hydrocodone . Hydrocodone is derived from codeine, which means it's a synthetic drug and is made from codeine, but actually does not contain it. Demerol and Dilaudid do not contain codeine.
