Treatment of Suspected Wernicke's Encephalopathy
Wernicke's encephalopathy is a serious neurological emergency requiring prompt clinical recognition and treatment. The threshold for action should be low: a high index of suspicion is essential, particularly when presentation may be confounded by intoxication or other factors.
This protocol addresses the management of suspected Wernicke's encephalopathy — cases where the clinical picture raises the possibility of this diagnosis, even before confirmation. Maintaining a high level of suspicion is a core part of safe management in this setting.
Treatment approach
The approach centres on prompt parenteral therapy, with continuation requirements and a defined transition to an oral regimen to follow.

- Maintain a high level of suspicion for the possibility of Wernicke's encephalopathy, particularly if the person is intoxicated.
- Parenteral treatment should be given for a minimum of 5 days, unless Wernicke's encephalopathy is excluded.
- Oral thiamine treatment should follow parenteral therapy.
- Thiamine should be given in doses toward the upper end of the 'British national formulary' range.
