OxyFAST is a brand name for the instant-release version of oxycodone, a pain reliever approved by the FDA in 1995. Instant-release oxycodone hydrochloride is a prescription medication which is available both as a generic drug and under brand names like OxyFAST and Endone. When oxycodone enters the central nervous system, it binds to opioid receptors located in the brain and spinal cord. This relieves pain by blocking out the bodys natural response to discomfort. Because of its instant-release formula, this medication is commonly prescribed for people, like cancer patients, who experience sudden bursts of pain. Immediate-release oxycodone is available in capsule or liquid form. Dosages range from 5 to 20 milligrams.Take oxycodone exactly as directed by your doctor and never take extra doses. Because oxycodone hydrochloride is highly addictive, it is classified by the FDA as a Schedule II drug, which means it is more tightly regulated than most medications.

Oxycodone instant-release should never be taken in conjunction with alcohol, antidepressants or antihistamines. Ask your doctor for a full list of medications and conditions that should not be combined with oxycodone.
