Another misconception that is incorrect is that the vitamin K injection increases the risk of jaundice. Vitamin K-related jaundice has only been documented in high-risk newborns (such as preterm babies) at dosages 30–60 times greater than what we provide. We recommend that all healthy term infants receive a dose of 2.5 mcg/kg, or 12.5 mg per kilo, of body weight. This should be done no later than 24 hours after birth and again at 1 month. The most common symptom of vitamin K deficiency is easy bruising. Other symptoms include confusion, depression, and stomach pain. A blood test can show reduced activity of factors needed for blood to clot properly. If you think your baby may be deficient in vitamin K, talk with your doctor about whether another form of treatment is better for your child. There are several options available including injections or pills that can raise his or her level of this vital nutrient.
