What is Percocet, and what is it used for?

Percocet (oxycodone/acetaminophen) is a strong narcotic pain-reliever and cough suppressant similar to morphine, codeine, and hydrocodone. Percocet is prescribed for the relief of moderate to moderately severe pain.

  • The precise mechanism of action of oxycodone is not known but may involve stimulation of opioid (narcotic) receptors in the brain. Oxycodone does not eliminate the sensation of pain but decreases discomfort by increasing tolerance to pain. In addition to tolerance to pain, oxycodone also causes sedation and respiratory depression.
  • Acetaminophen is a non-narcotic pain reliever and antipyretic (fever reducer). Acetaminophen relieves pain by elevating the threshold to sensing pain. It reduces fever through its action on the heat-regulating center of the brain.
  • The combination of oxycodone and acetaminophen achieves greater pain relief than either taken separately.
  • The FDA approved oxycodone/acetaminophen combinations in February 1980.
