Percocet E712 contains both Hydrocodone/Acetaminophen 10-325 mg and Oxycodone. Oxycodone is one opioid pain reliever. Opioids fall under the category of “narcotics.” Oxycodone’s effects are enhanced by the less potent analgesic acetaminophen. Percocet is a medication that can be used to treat mild to severe pain. Due to the hazards of addiction, abuse, and overuse, even at permitted doses, Percocet is only use when non-opioid medicines have either failed to relieve pain or have done so only partially.
