The combination oxycodone/paracetamol (Paracetamol is called "acetaminophen" in the United States and well known by the trademarked name, "Tylenol") (North American trade name Percocet, generic endocet and ratio-oxycocet in Canada) is a narcotic pain reliever used to treat moderate to severe acute (short-term) pain, marketed by Endo Pharmaceuticals.[1]


The U.S. Food and Drug Administration first approved Percocet in 1976, under application ANDA 085106.[2]


As of March 2006, Endo Pharmaceuticals produces Percocet in following dosages.[3] Percocet tablets are available in six combinations of oxycodone hydrochloride and Paracetamol / acetaminophen, with different appearances and maximum daily doses:[3]

Oxycodone Hydrochloride (mg) Paracetamol (Acetaminophen) (mg) Tablet Color Tablet Shape Maximum Daily Dose
2.5 325 pink oval 12 tablets
5 325 white round 12 tablets
7.5 325 peach oval 8 tablets
7.5 500 peach capsule-shaped 8 tablets
10.0 325 white oblong 8 tablets
10.0 650 yellow oval 6 tablets

For the 2.5 mg Oxycodone HCl tablet, the usual dose is 1–2 tablets every six hours as needed for pain; for the other tablets, the usual dose is 1-2 tablets every four to six hours as needed for pain.

Implicated in deaths

On June 30, 2009, an FDA advisory panel recommended that Percocet, Vicodin, and every other combination of acetaminophen with narcotic analgesics[4] be limited in their sales because of their contributions to an alleged 400 acetaminophen related deaths in the United States each year, that were attributed to acetaminophen overdose and associated liver damage.[5]

In December 2009, the Canadian Medical Association Journal reported a study finding a fivefold increase in oxycodone-related deaths in Ontario (mostly accidental) between 1991 and 2007 that led to a doubling of all opioid-related Ontario deaths over the same period.[6][7][8]
