Complicated alcohol abstinence is a medical emergency. The health care provider should be consulted promptly.

An examination of the neuromuscular system may show increased startle reflex, rapid rhythmic muscle tremor, or other changes indicating alcohol withdrawal. Evidence of increased autonomic function such as profuse sweating may be present. There may be symptoms of dehydration or malnutrition and signs indicating electrolyte disturbances. An eye inspection may show abnormalities of eye muscle movement such as lid lag. The heart rate may be rapid and there may be an irregular heart beat. The blood pressure may be normal or low.

A serum toxicology screen is usually positive for alcohol. Serum chemistry (chem-20) may show electrolyte disturbances, especially decreased levels of potassium and magnesium. An ECG (electrocardiogram) may show arrhythmias. An EEG (electroencephalogram) may be performed to rule out other causes of seizures.
