Answer

Vitamin K toxicity is typically seen in formula-fed infants or those receiving synthetic vitamin K-3 (menadione) injections. Because of its toxicity, menadione is no longer used for treatment of vitamin K deficiency.

The effects of vitamin K toxicity can include jaundice in newborns, hemolytic anemia, and hyperbilirubinemia. Toxicity also blocks the effects of oral anticoagulants.
