Alcohol Withdrawal Timeline: What to Expect
A clinical overview of the alcohol withdrawal timeline — from early symptoms to delirium tremens — and how Keystone Health Group manages each stage.
Alcohol withdrawal is a potentially life-threatening medical process that occurs when a person with physical alcohol dependence stops or significantly reduces their alcohol intake. Understanding the alcohol withdrawal timeline helps clients and families know what to expect during medically supervised detox. At Keystone Health Group, our medical team monitors and manages every stage of alcohol withdrawal using the CIWA-Ar protocol.
6–12 Hours: Early Withdrawal
Early alcohol withdrawal symptoms typically begin 6–12 hours after the last drink. These include anxiety, tremors, sweating, nausea, vomiting, headache, and elevated heart rate and blood pressure. These symptoms reflect the brain's hyperexcitable state as the suppressive effects of alcohol wear off.
12–48 Hours: Seizure Risk
Alcohol withdrawal seizures most commonly occur 12–48 hours after the last drink. These are generalized tonic-clonic seizures that can occur without warning. Our medical team monitors for seizure risk and administers preventive benzodiazepine therapy for clients at elevated risk.
48–96 Hours: Delirium Tremens
Delirium tremens (DTs) — the most severe form of alcohol withdrawal — typically begins 48–96 hours after the last drink. DTs are characterized by severe confusion, agitation, hallucinations, fever, and autonomic instability. Without treatment, DTs carry a mortality rate of 5–15%. With appropriate medical management, mortality is less than 1%.
Days 5–7: Resolution
For most clients, the acute withdrawal phase resolves within 5–7 days. Post-acute withdrawal syndrome (PAWS) — with anxiety, insomnia, and mood disturbance — can persist for weeks to months.
