Vitamin K is a fat-soluble vitamin which is essential for blood clotting. A lack of vitamin K can lead to unwanted bleeding. Most people can get sufficient vitamin K from the food they eat. It occurs naturally in many foods, especially leafy green vegetables such as cabbage and spinach, and also in avocado, meat, milk, and some cereals.
Newborn babies have relatively low amounts of vitamin K in their bodies. Because of this they can be at risk of bleeding, particularly during the first few weeks of life. To prevent this, they are given phytomenadione (a type of vitamin K) soon after birth. It is given either as a liquid for your baby to swallow, or as an injection. If your baby is given it by injection, one dose soon after your baby is born is usually sufficient. If it is given by mouth, your baby will be given one dose soon after birth and a second dose 4-7 days later. If you are breast-feeding your baby, your baby will either need a third dose at 1 month of age, or alternatively you will be asked to give your baby a dose each week for a total of 12 weeks.
People who take anticoagulant medicines such as warfarin can also be at risk of bleeding. This can happen if their dose of the anticoagulant is too high. Phytomenadione is given as an antidote to prevent bleeding caused by anticoagulant medicines. If this happens, it is likely to be given by injection in hospital.
