Oxycodone is strictly restricted in the United States under the Controlled Substances Act (CSA) because of its addictive tendency. When prescribing it, doctors have to go by certain state and federal regulations, and pharmacists have to keep an eye out for any abuse. Prescription drug monitoring programs (PDMPs) have been put in place in numerous states to track patient prescriptions and reduce overprescription. The U.S. Drug Enforcement Administration (DEA) keeps a tight eye on its distribution.
