Phenobarbital, Diazepam Equally Effective in Alcohol Detox

Several medications get used at hospitals for the treatment of alcohol withdrawal. A study published in JAMA Internal Medicine compared phenobarbital with diazepam.

Researchers looked at hospital stays and other outcomes to see whether one medication offered an advantage over the other and the findings showed little difference between the two.

Study Included 754 Hospitals

Researchers evaluated data from the Premier Healthcare Database that focused on 24,643 adults treated for alcohol withdrawal at 754 hospitals.

Alcohol withdrawal was the primary reason each patient was admitted and treatment began with either phenobarbital or diazepam that same day. About 48% received phenobarbital and 52% received diazepam. The median age was 45 and around 75% of the patients were men.

Researchers used statistical analysis and machine learning to compare the results, while accounting for differences among patients. They planned to estimate how the two medications might compare if patients had been assigned to receive one or the other randomly.

Hospital Stays and Complications Were Similar

Patients receiving phenobarbital stayed in the hospital for an average of 4.1 days and those treated with diazepam stayed for 4.3 days, a statistically small difference.

Rates of invasive mechanical ventilation were also similar. About 3.1% of patients in the phenobarbital group needed a ventilator compared with 2.7% of those who received diazepam.

One difference involved patients who left the hospital against medical advice. This happened in 9.5% of patients who started phenobarbital compared with 12.6% of those who received diazepam.

The study could not explain why more patients in the diazepam group left early. Patient preferences and differences in symptom control are possible factors but the data did not establish a cause.

Why the Comparison Matters

Phenobarbital has become more common in alcohol withdrawal treatment. However much of the previous research compared it with lorazepam rather than diazepam.

Diazepam is a long-acting benzodiazepine that has been used to manage alcohol withdrawal for years. Comparing it with phenobarbital gives hospitals more information about how the two medications perform in routine care.

The findings suggest neither drug had a clear advantage in the outcomes researchers measured. The authors said randomized trials are still needed to confirm the results.

Medical Supervision Is Important During Withdrawal

People experiencing alcohol withdrawal may need medical care to manage their symptoms safely. This study found similar outcomes with phenobarbital and diazepam in hospitalized patients but treatment decisions still depend on each person’s condition and medical history.

Severe alcohol withdrawal can potentially cause seizures and delirium. It may even become life-threatening. People who’ve been drinking heavily for a long time should not try to stop suddenly without medical guidance.

Medically supervised detox provides monitoring and treatment during withdrawal. Healthcare providers can also help patients plan for ongoing care after the initial symptoms have passed.
