Percocet is a prescription medication that combines oxycodone, an opioid pain reliever, with acetaminophen, a non-opioid pain reliever and fever reducer. This combination helps manage moderate to severe pain when other treatments are not effective. Oxycodone works by acting on opioid receptors in the brain, while acetaminophen enhances the overall pain-relieving effect. Percocet is often prescribed after surgery or injury and should be taken exactly as directed by a healthcare professional. Because it contains an opioid component, Percocet carries a risk of dependence and misuse if not used properly. Common side effects may include drowsiness, nausea, constipation, and dizziness. Patients should not exceed the recommended dose, particularly because excessive acetaminophen intake can harm the liver.
