Magnesium must be corrected concurrently with thiamine supplementation
Prevention strategies
Routine thiamine supplementation for all patients admitted for alcohol use disorder
Thiamine added to all TPN formulations before any carbohydrate infusion
Risk-stratified thiamine protocols for bariatric surgical patients
Patient Discharge Instructions
copy discharge instructions
Diagnosis and key information
You were treated for Wernicke's encephalopathy, a serious brain condition caused by severe vitamin B1 (thiamine) deficiency
Your brain requires thiamine to function normally; without it, critical areas are damaged
Early treatment with IV thiamine can reverse most symptoms, but delays can lead to permanent memory problems
Medications after discharge
Take thiamine 100 mg by mouth every day without stopping
Take all prescribed vitamins and supplements as directed
Do not miss doses; skipping thiamine can cause your symptoms to return
Diet and nutrition
Eat regular balanced meals including thiamine-rich foods: whole grains, legumes, pork, and fortified cereals
Avoid diets consisting mainly of refined carbohydrates or polished rice, which increase thiamine requirements
Attend any scheduled nutrition counseling appointments
Alcohol cessation
Alcohol consumption was a primary cause of your thiamine deficiency; continued drinking will cause recurrence
Resources for alcohol treatment: your family doctor, addiction medicine referral, or local support groups
Naltrexone or acamprosate may be prescribed by your doctor to help reduce alcohol craving
Activity and safety
Balance and walking problems may persist; use caution on stairs and uneven surfaces
Do not drive until your doctor confirms it is safe
Arrange for someone to stay with you if you still feel confused or unsteady
Return to emergency department immediately for
New or worsening confusion, disorientation, or inability to recognize familiar people
Sudden changes in vision, double vision, or inability to move your eyes normally
Inability to walk or sudden worsening of unsteadiness
Seizure
Chest pain, severe shortness of breath, or leg swelling
High fever, severe headache, or stiff neck
Hypothermia or feeling very cold despite being covered
Follow-up appointments
See your family physician or neurologist within 1-2 weeks of discharge
Neuropsychological testing if memory problems persist (to evaluate for Korsakoff syndrome)
Addiction medicine referral arranged at discharge
