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.
