No child should suffer from vitamin K deficiency‐induced bleeding disorders

We encountered an 11‐day‐old male neonate with vitamin K deficiency‐induced intracranial hemorrhage, despite receiving oral vitamin K₂ (menaquinone‐4) prophylaxis according to Japanese guidelines. This case suggests that the current vitamin K deficiency‐bleeding prophylaxis programs cannot prevent bleeding completely. Better prophylaxis programs using both intramuscular and oral administration should be considered.
