Oxycodone, sold under various brand names such as Roxicodone and OxyContin (which is the extended release form), is a semi-synthetic opioid used medically for treatment of moderate to severe pain. It is highly addictive[14] and is a commonly abused drug.[15][16] It is usually taken by mouth, and is available in immediate-release and controlled-release formulations.[15] Onset of pain relief typically begins within fifteen minutes and lasts for up to six hours with the immediate-release formulation.[15] In the United Kingdom, it is available by injection.[17] Combination products are also available with paracetamol (acetaminophen), ibuprofen, naloxone, naltrexone, and aspirin.[15]

Common side effects include euphoria, constipation, nausea, vomiting, loss of appetite, drowsiness, dizziness, itching, dry mouth, and sweating.[15] Side effects may also include addiction and dependence, substance abuse, irritability, depression or mania, delirium, hallucinations, hypoventilation, gastroparesis, bradycardia, and hypotension.[15] Those allergic to codeine may also be allergic to oxycodone.[15] Use of oxycodone in early pregnancy appears relatively safe.[15] Opioid withdrawal may occur if rapidly stopped from withdrawal.[15] Oxycodone acts by activating the μ-opioid receptor.[18] When taken by mouth, it has roughly 1.5 times the effect of the equivalent amount of morphine.[19]

Oxycodone was originally produced from the opium poppy opiate alkaloid thebaine in 1916. It was first used medically in Germany in 1917.[20] It is on the World Health Organization's List of Essential Medicines.[21] It is available as a generic medication.[15] In 2021, it was the 59th most commonly prescribed medication in the United States, with more than 11 million prescriptions.[22][23] A number of abuse-deterrent formulations are available, such as in combination with naloxone or naltrexone.[16][24]
