Opioids What company makes the dilaudid 4mg with the D imprint ?

[THE_REAL_OBLIVION]

I'm familiar with most companies and logos, i know the @ are Abbott, K for Knoll, and the generics usually have a sign easily identifiable on the internet but I was prescribed "brand name" dilaudid which says Dilaudid and that's it. There's a 4 and a D imprint. I did my best with google and even bing, but no dice. Anybody here knows ?

Edit : I looked even more and it seems like it's Purdue brand dilaudid according to this :

but other info is contradicting this saying the imprint is P not D when made by Purdue....or is that the american ones ? Any help would be extremely appreciated.

D 4 is the Canadian imprint for Dilaudid manufactured by Purdue
P 4 is the American one.
