Opioid withdrawal
Background
- Withdrawal can be precipitated with administration of antagonist (e.g. naloxone) or partial agonist (e.g. buprenorphine).
- Symptoms are usually uncomfortable but not life-threatening
- Catecholamine surge during withdrawal may cause a level of hemodynamic instability that may not be tolerated by patients with co-morbid conditions
- life-threatening in neonates
- Onset is 6-12hr after last heroin use, within 30hr after last methadone use
