Can someone please clarify if Oxycontin 30mg is immediate release or extended release? I don't know that much about oxycontin/oxycodone & the pill identifier doesn't specify. (Or I didn't find it if it does) I thought Oxycodone was IR & Oxycontin extended release but I've seen places that say oxycontin is IR also. Can someone please clarify. .thx so much!
