Percocet is a prescription painkiller that combines oxycodone, a powerful opioid, with acetaminophen, a non-opioid pain reliever. It is used to treat moderate to severe pain but carries a high risk of addiction, dependence, and overdose, especially with prolonged use. Oxycodone affects the brain’s opioid receptors, altering pain perception and inducing euphoria, while acetaminophen helps reduce fever and enhance pain relief. Misuse can lead to respiratory depression, liver damage, or fatal overdose. Percocet should only be taken as prescribed and avoided with alcohol or other depressants. Due to its addictive potential, it is classified as a Schedule II controlled substance.
