Phytomenadione (Phytomenadione)

Phytomenadione is a vitamin K1 found in green leafy vegetables and vegetable oils. However, in medicine, synthetic phytomenadione is more often used, which is prescribed as an antidote for an overdose of anticoagulants.

Phytomenadione is involved in the synthesis of prothrombin, a blood plasma protein necessary for normal blood clotting. With a lack of vitamin K in the body, the synthesis of prothrombin is disrupted, which leads to increased bleeding.

In medicine, phytomenadione is used in the form of a solution for intramuscular or intravenous injections for hypoprothrombinemia caused by vitamin K deficiency or taking anticoagulants. It quickly restores normal hemostasis.

One of the trade names of phytomenadione is Konakion - an injection solution containing 10 mg of phytomenadione in 1 ml.



Phytomenadione is a type of vitamin K that is present in green plants and promotes the formation of prothrombin in the body. It is used as an antidote to treat overdose of various anticoagulants such as warfarin or heparin, which can lead to bleeding.

Synthetic phytomenadione can be obtained from plant sources such as soy or carrots, but more often a synthetic preparation is used. It is administered intravenously or orally and helps restore normal prothrombin formation.

Phytomenadione can also be used as a prophylactic agent to prevent overdose of anticoagulants. This is especially important for people who are taking blood thinning medications such as aspirin or clopidogrel.

However, phytomenadione is not a panacea and cannot replace treatment with anticoagulants for serious bleeding. If you suspect an overdose of an anticoagulant, seek medical attention immediately.



Phytomenadione is a substance found in green plants and is important for human health. It belongs to a group of vitamins called vitamin K and plays an important role in the blood clotting process in the body.

Phytomenadione is a precursor of prothrombin, a protein necessary for the blood clotting process. If there is a deficiency of it or an overdose of an anticoagulant (a substance that prevents blood clotting), the body cannot form a sufficient amount of prothrombin. In such cases, bleeding or even death may occur.

In case of overdose of an anticoagulant, phytomenadione can be used as an antidote. It helps the body restore normal levels of prothrombin and prevent serious consequences.

Synthetic phytomenadione is available as a drug called konakion. It can be purchased at a pharmacy or ordered online. However, you should consult your doctor before use.

In conclusion, phytomenadione is an important component of a healthy lifestyle and can provide significant assistance in the treatment and prevention of various blood-related diseases.
