🩺 Signs
Tremors, anxiety, ↑ HR/BP
Sweating, N/V, insomnia 6–24h
DTs: confusion, hallucinations, fever
🧪 Meds

CIWA scoring, seizure precautions
Quiet room, frequent reorient
🚩 Report
Seizures, ↑↑ vitals = emergency
DTs untreated = death
📚 Alcohol Withdrawal (DTs) — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Alcohol withdrawal occurs when a person physically dependent on alcohol abruptly stops or reduces intake, causing CNS hyperexcitability. Symptoms begin within 6 to 24 hours; delirium tremens (DTs) is the most severe form, peaking around 48 to 72 hours, and can be fatal. Benzodiazepines are the treatment of choice and the CIWA scale guides dosing.
🔑
Key points
Understand these first
Early withdrawal (6-24 hours) brings tremors, anxiety, nausea, diaphoresis, and elevated vital signs.
Withdrawal seizures typically occur within 12 to 48 hours.
Delirium tremens (48-72 hours) features severe confusion, agitation, hallucinations, fever, and autonomic instability.
DTs carry significant mortality risk if untreated.
Thiamine deficiency can cause Wernicke encephalopathy; give thiamine before glucose.
Benzodiazepines are tapered to control CNS hyperactivity and prevent seizures.
✅
Nursing priorities
What to do, in order
Assess withdrawal severity using the CIWA-Ar scale and monitor vital signs frequently.
Administer scheduled or symptom-triggered benzodiazepines per protocol.
Give thiamine, folate, and multivitamins; administer thiamine before any glucose.
Provide a calm, quiet, well-lit environment and institute seizure and fall precautions.
Maintain hydration and correct electrolyte imbalances such as magnesium.
🚩
Red flags — report now
Escalate immediately
Delirium tremens with hyperthermia, severe tachycardia, and hypertension is a medical emergency.
Withdrawal seizures require immediate intervention and seizure precautions.
Giving glucose before thiamine can precipitate Wernicke encephalopathy.
Rapidly rising vital signs and worsening confusion signal escalating, potentially fatal withdrawal.
🧪
Labs & values
Numbers to know
Magnesium 1.5-2.5 mg/dL (often low and worsens seizure risk)
Potassium 3.5-5.0 mEq/L
AST/ALT elevated and GGT elevated with chronic alcohol use
🗣️
Patient teaching
What patients must know
Withdrawal can be dangerous; medically supervised detox is essential, never quit alone if dependent.
Take thiamine and vitamins as prescribed to prevent brain complications.
Connect with support programs and avoid all alcohol after detox.
