Opioid use disorder
Opioid drugs include morphine and codeine (natural opiates); heroin, oxycodone, oxymorphone, hydrocodone, hydromorphone, and buprenorphine (semi-synthetic opioids); and meperidine (Demerol), fentanyl and fentanyl analogs such as carfentanil, and methadone (synthetic opioids). Routes of drug administration include oral, inhalation (smoking), intranasal (snorting), subcutaneous ("skin popping"), and intravenous.
Opioid use disorder is the habitual use of any in a group of opioid drugs, leading to a state of opioid intoxication and/or dysfunctional behavior, with significant long-term adverse effects. The disorder can range from mild to severe. The individual may experience a growing tolerance and onset of withdrawal symptoms. Opioid withdrawal syndrome may present with profuse sweating, hypertension, nausea, vomiting, fever, anxiety, and lacrimation. (For discussion of withdrawal symptoms in neonates due to maternal use of opioids during pregnancy, see Neonatal abstinence syndrome.)
Patients dependent on opioid pain medications who are unable to obtain prescriptions legally may pursue opioids through alternate means. Persons using diverted opioids or street drugs face a greater risk of overdose and death due to inconsistency of strength / dosage, drug interactions, or contamination of supply.
Opioid toxicity can be life-threatening. Opioid users who are experiencing withdrawal or detoxification are most prone to overdose and death if they take their usual dosage.
Drugs approved by the US Food and Drug Adminstration (FDA) for medication-assisted treatment for opioid addiction include methadone, buprenorphine, naltrexone, and lofexidine.
Devices with cranial nerve stimulation may help reduce symptoms of acute opioid withdrawal.
Note: Children of parents with opioid use disorder are at increased risk for neglect and/or abuse.
