Oxycodone is a pain reliever containing hydrocodone and oxycodone, two active ingredients. Oxycodone produces a unique effect on the body that relieves pain in many situations. It has an immediate (immediate-release) dose, which releases the drug immediately into the bloodstream or tissues; an extended-release tablet that is released gradually at once throughout the day; and a short-acting (short-acting) dosage that delivers its full effects within minutes.
