A patient with severe alcohol use disorder is on a diazepam (Valium) taper. Three days after initiation, the patient becomes drowsy and off-balance. Which change to the treatment plan is most appropriate?

• A. Extend the Valium taper
• B. Change to Serax
• C. D/C the Valium taper
• D. Change to Methadone

Answer: (B)

In managing alcohol withdrawal with benzodiazepines, safety of liver metabolism is a key factor. Diazepam is very long-acting and has active metabolites, so in a patient with severe alcohol use disorder (who may have liver impairment) it can accumulate and cause excessive sedation and unsteadiness. Switching to Serax, which is oxazepam, is preferred because it is metabolized by simple conjugation (glucuronidation) and has no active metabolites. This makes it safer for the liver and reduces the risk of oversedation, while still providing adequate benzodiazepine effect to support withdrawal management. The shorter, more predictable action helps control drowsiness and ataxia as taper continues.

Extending the Valium taper would prolong the sedative exposure; stopping the taper abruptly risks withdrawal symptoms; methadone is used for opioid withdrawal/maintenance, not alcohol withdrawal.
