Opioids are a class of drugs that include natural opiates (morphine, codeine), semi-synthetic opioids (heroin, oxycodone, hydrocodone), and fully synthetic opioids (fentanyl, tramadol). All produce pain relief and euphoria by binding to opioid receptors in the brain, and all carry risk of physical dependence and use disorder.
Prescription Opioids and Addiction
Opioid use disorder frequently begins with a legitimate prescription. Oxycodone, hydrocodone, and morphine are commonly prescribed for pain; dependence can develop within weeks of daily use. Many people transition from prescription opioids to heroin or fentanyl when prescriptions run out or costs increase.
Medication-Assisted Treatment for Opioids
The FDA has approved three medications for opioid use disorder: buprenorphine (Suboxone), methadone, and naltrexone (Vivitrol). All three are evidence-based and dramatically reduce the risk of relapse, overdose, and death. Placement advisors can connect callers with licensed inpatient programs that include MAT as part of the treatment model.
