5.6 Substance Misuse and Withdrawal

Key Takeaways Explain This Topic AI

Alcohol withdrawal can progress to Delirium Tremens (DTs), a life-threatening emergency characterized by severe hypertension, tachycardia, hallucinations, and seizures

Alcohol withdrawal symptoms typically begin 6-24 hours after last drink, with DTs occurring 48-72 hours after cessation

Benzodiazepines (Lorazepam, Diazepam) are first-line treatment for alcohol withdrawal to prevent seizures

Opioid withdrawal is extremely uncomfortable but rarely life-threatening; symptoms include rhinorrhea, lacrimation, muscle aches, and diarrhea

Naloxone (Narcan) reverses opioid overdose but has a shorter half-life than most opioids, requiring monitoring for re-sedation

Last updated: January 2026

Substance use disorders are common in healthcare settings. Nurses must recognize withdrawal syndromes, understand their timelines, and implement appropriate interventions. The NCLEX tests your knowledge of the most dangerous withdrawal syndromes and their management.

The Danger Hierarchy of Withdrawal

Not all withdrawal syndromes are equally dangerous. Know which ones can kill:

Substance Withdrawal Danger Level Can Be Fatal?

  • Alcohol High Yes (DTs, seizures)
  • Benzodiazepines High Yes (seizures)
  • Barbiturates High Yes
  • Opioids Moderate Rarely (discomfort extreme)
  • Cocaine/Stimulants Low No (depression, fatigue)
  • Cannabis Low No
  • Nicotine Low No

Critical point: Alcohol and benzodiazepine withdrawal can cause fatal seizures and require medical management. Opioid withdrawal, while extremely uncomfortable, is rarely life-threatening.

  • Alcohol Withdrawal
  • Timeline of Alcohol Withdrawal
  • Time After Last Drink Stage Symptoms
  • 6-24 hours Minor withdrawal Tremors, anxiety, nausea, insomnia, tachycardia
  • 12-24 hours Alcoholic hallucinosis Visual/auditory/tactile hallucinations (client knows they're not real)
  • 24-48 hours Withdrawal seizures Grand mal seizures possible
  • 48-72 hours Delirium Tremens (DTs) Life-threatening medical emergency
  • Delirium Tremens (DTs)

Delirium Tremens is the most severe form of alcohol withdrawal and is a medical emergency with 5-15% mortality if untreated.

Symptoms:

  • Severe confusion and disorientation
  • Severe agitation
  • Profuse sweating (diaphoresis)
  • High fever
  • Severe hypertension
  • Tachycardia
  • Visual/tactile hallucinations (often insects, snakes)
  • Tremors
  • Seizures

Risk factors for DTs:

  • History of DTs
  • Heavy, prolonged alcohol use
  • Concurrent medical illness
  • Previous withdrawal seizures
  • Older age
  • Nursing Assessment: CIWA-Ar

The Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) is used to monitor withdrawal severity. Scores determine medication dosing.

  • CIWA-Ar Score Severity Intervention
  • 0-8 Minimal Monitor closely
  • 9-14 Mild May need medication
  • 15-20 Moderate Medication indicated
  • >20 Severe Aggressive treatment
  • Treatment of Alcohol Withdrawal
  • First-line medications: Benzodiazepines
  • Medication Route Key Points
  • Lorazepam (Ativan) PO, IM, IV Preferred in liver disease (no active metabolites)
  • Diazepam (Valium) PO, IV Long-acting; self-tapering
  • Chlordiazepoxide (Librium) PO Traditional choice; oral only

Other interventions:

  • Thiamine (Vitamin B1) - GIVE BEFORE GLUCOSE to prevent Wernicke's encephalopathy
  • IV fluids for dehydration
  • Electrolyte replacement
  • Seizure precautions
  • Quiet, well-lit environment
  • Frequent vital signs
  • Fall precautions

Exam tip: Always give thiamine BEFORE dextrose (glucose) in alcoholic clients. Glucose metabolism depletes thiamine and can precipitate Wernicke's encephalopathy.

  • Opioid Withdrawal
  • Timeline of Opioid Withdrawal
  • Opioid Type Onset of Withdrawal Peak Duration
  • Short-acting (heroin, oxycodone) 6-12 hours 36-72 hours 5-7 days
  • Long-acting (methadone) 24-48 hours 72-96 hours 2-3 weeks
  • Symptoms of Opioid Withdrawal
  • Mnemonic: Think "Flu-Like" symptoms
  • System Symptoms
  • Eyes/Nose Lacrimation (tearing), rhinorrhea (runny nose)
  • GI Nausea, vomiting, diarrhea, abdominal cramps
  • Musculoskeletal Muscle aches, joint pain
  • Autonomic Piloerection (goosebumps), sweating, yawning
  • Other Dilated pupils, restlessness, insomnia, anxiety
  • Nursing Care for Opioid Withdrawal
  • Comfort measures (blankets for chills, fluids for dehydration)
  • Antiemetics for nausea/vomiting
  • Antidiarrheals (loperamide)
  • Clonidine to reduce autonomic symptoms

Medication-assisted treatment (MAT):

  • Methadone (full agonist)
  • Buprenorphine (partial agonist)
  • Naltrexone (antagonist - for maintenance, not acute withdrawal)
  • Opioid Overdose
  • Signs of Opioid Overdose

The classic triad:

  • Respiratory depression (slow, shallow breathing)
  • Pinpoint pupils (miosis)
  • Decreased level of consciousness
  • Emergency Response

Naloxone (Narcan) is the antidote for opioid overdose.

  • Route Onset Duration
  • IV 2 minutes 30-90 minutes
  • IM 5 minutes 30-90 minutes
  • Intranasal 5 minutes 30-90 minutes

Critical nursing considerations:

  • Naloxone has a SHORTER half-life than most opioids
  • Client may need repeated doses
  • Monitor closely for re-sedation after initial reversal
  • Naloxone will precipitate immediate withdrawal in dependent individuals
  • Be prepared for agitation when client wakes up
  • Benzodiazepine Withdrawal

Similar to alcohol withdrawal (both affect GABA receptors).

Symptoms:

  • Anxiety, irritability
  • Tremors
  • Sweating
  • Seizures (can be fatal)
  • Rebound insomnia

Treatment:

  • Gradual taper (never stop abruptly)
  • Long-acting benzodiazepine for substitution
  • Seizure precautions
  • Stimulant Withdrawal (Cocaine, Amphetamines)

Symptoms ("Crash"):

  • Severe depression
  • Fatigue, increased sleep
  • Increased appetite
  • Irritability
  • Suicidal ideation

Nursing care:

  • Monitor for depression and suicide risk
  • Supportive care
  • Ensure sleep and nutrition
  • No pharmacological treatment typically needed
  • Quick Reference: Withdrawal Comparison
  • Substance Life-Threatening? Key Symptoms Treatment
  • Alcohol Yes Tremors, seizures, DTs Benzodiazepines, thiamine
  • Opioids Rarely "Flu-like" symptoms Clonidine, MAT
  • Benzodiazepines Yes Anxiety, seizures Gradual taper
  • Cocaine No Depression, fatigue Supportive care
  • On the Exam

NCLEX priorities:

  • Alcohol withdrawal can kill - seizures, DTs
  • DTs = 48-72 hours after last drink
  • Benzodiazepines treat alcohol withdrawal
  • Thiamine before glucose in alcoholics
  • Opioid withdrawal = uncomfortable, not deadly
  • Naloxone = short half-life = watch for re-sedation
