Not Medical Advice: Pill imprint OP 40 has been identified as Oxycontin 40 mg.
OxyContin is the brand name for a timed-release formula of oxycodone, a narcotic analgesic (medication that reduces pain). It's used to relieve pain from injuries, arthritis, cancer, and other conditions. Oxycodone, a morphine-like drug, is found along with non-narcotic analgesics in a number of prescription drugs, such as Percodan (oxycodone and aspirin) and Percocet (oxycodone and acetaminophen).
OxyContin contains between 10 and 80 milligrams of oxycodone in a timed-release formula that allows up to 12 hours of relief from chronic pain. What distinguished OxyContin from other analgesics was its long-acting formula, a blessing for patients who typically need round-the-clock relief.
