Percocet is a prescription medication that is a combination of two active ingredients: oxycodone and acetaminophen. Oxycodone is an opioid pain reliever, and acetaminophen is a non-opioid pain reliever and fever reducer. Percocet is primarily used for the management of moderate to moderately severe pain. It provides pain relief by binding to specific opioid receptors in the brain and spinal cord, reducing the perception of pain. The addition of acetaminophen enhances the pain-relieving effects of oxycodone.
