Phytomenadione injection

About phytomenadione

Vitamin K is a fat-soluble vitamin which is essential for blood clotting. It also plays a role in bone health.

People who take anticoagulant medicines such as warfarin are at risk of bleeding. Regular blood tests are needed to check on how quickly the blood clots. The aim is to get the dose of warfarin just right so that the blood does not clot as easily as normal, but not so much as to cause bleeding problems. If the dose of the anticoagulant is too high then bleeding can become a problem. Phytomenadione is given as an antidote to bleeding caused by anticoagulant medicines such as warfarin. It is likely to be given by injection in hospital.

If a person who is taking a medicine like warfarin needs to have an operation at short notice then the effects of the anticoagulant medicine will need to be reversed before the surgery takes place. Vitamin K is given to reduce the risk of bleeding during the surgery.

Vitamin K is given to newborn babies soon after birth to prevent possible bleeding problems. It is usually given as an injection but the liquid medicine can also be swallowed. If you have been asked to give the medicine by mouth, your doctor or midwife will give you instructions on how much to give and when.

How phytomenadione is given

• Phytomenadione injection will be given by a doctor or nurse. Ask to read the manufacturer's printed information leaflet from inside the pack - it will give you more information about treatment with phytomenadione.

• You may be given the injection to swallow by mouth. This is often the case for people who are taking phytomenadione before surgery, or who have abnormal blood results but who do not have any symptoms of bleeding.

• If you have been asked to give phytomenadione to your newborn baby by mouth, follow the midwife's or doctor's instructions carefully. Read the printed manufacturer's instructions on how to use the ampoule and dropper. A dose is usually needed at 1 week old and then at 1 month old.
