1. What is Konakion 10 mg/ml and what is it used for

Konakion contains as active substance phytonadione Vitamin K which intervenes in the blood coagulation mechanism. A lack of vitamin K1causes an increase in the tendency to bleed.

It is used for the treatment and prevention of bleeding (hemorrhages).

Prevention andtreatment of hypoprothrombinemia (lack of a substance, prothrombin, needed for blood to clot) caused by vitamin K deficiency.

Therefore, it is indicated for bleeding or risk of bleeding due to severe hypoprothrombinemia caused by:

Overdosing of anticoagulant medications derived from coumarin in patients who take them (medications that prevent the formation of clots)
Lack of vitamin K (hypovitaminosis K) caused by factors that decrease vitamin K absorption or synthesis, such as obstructive jaundice (disorder of bile secretion into the intestine), intestinal or hepatic alterations, and prolonged treatment with antibiotics, sulfonamides (chemical substances that can be used as antibiotics) or salicylates(for example, acetylsalicylic acid).

Konakion 2 mg/0.2 ml pediatric is used for the prevention and treatment of hemorrhagic disease in newborns.

>9	2.5 to 5 mg (up to 10 mg)	1 mg
Acenocoumarol	5-8	1 to 2 mg	1 to 2 mg

CCP, prothrombin complex concentrate

Hypoprothrombinemia due to other causes

In hypoprothrombinemia due to absorption disorders or treatment with antibiotics, salicylates or sulfonamides, a dose of 2 mg of Konakion 10 mg/ml can be administered orally or injectable in adults. Konakion should be administered at the lowest effective dose.

The dose and administration route will depend on the severity of the deficiency and the response to the medication.

Older patients

Older patients tend to be more sensitive to the effect of this medication. Therefore, the dose in this group should be set at the lower limits of the recommended values. It has been shown that small doses of 0.5 to 1 mg of vitamin K1 by intravenous or oral route effectively reduce INR to <5.

Use in children

Children over one year

The doctor will decide on the appropriate dose based on the indication and weight of the patient. It has been reported that a single dose corresponding to one-tenth of the total intravenous dose of vitamin K1 in adults is effective in reversing asymptomatic elevations of INR (>8) in clinically well children.

Newborns and children under one year

For this group of patients, due to the small dose required, Konakion 2 mg/0.2 ml pediatric should be used.

Normally, Konakion will be administered as a single dose, but if your response is not sufficient, you may be able to repeat the administrations.
