1. What is Konakion 10 mg/ml and what is it used for
Konakion contains the active substance phytomenadione, Vitamin K that intervenes in the blood coagulation mechanism. The lack of Vitamin K1 causes an increase in the tendency to bleed.
It is used for the treatment and prevention of bleeding (hemorrhages).
Konakion 10 mg/ml is indicated in:
Prevention and treatment of hypoprothrombinemia (lack of a substance, prothrombin, needed for blood to clot) caused by Vitamin K deficiency.
Therefore, it is indicated in hemorrhages or risk of hemorrhages due to severe hypoprothrombinemia caused by:
- overdose of anticoagulant medications derived from coumarin in patients taking them (medications that prevent the formation of blood clots)
- lack of Vitamin K (hypovitaminosis K) caused by factors that decrease the absorption or synthesis of Vitamin K, such as obstructive jaundice (disorder of bile secretion to the intestine), intestinal or hepatic disorders, and after prolonged treatment with antibiotics, sulfonamides (chemical substances that can be used as antibiotics), or salicylates (e.g., acetylsalicylic acid).
For the prevention and treatment of hemorrhagic disease of the newborn, Konakion 2 mg/0.2 ml pediatric is used.

Severe or very severe bleeding, e.g., during anticoagulant therapy:
After discontinuation of treatment with the coumarin anticoagulant you are taking, a dose of 5-10 mg of Konakion will be administered slowly (for at least 30 seconds) intravenously, along with fresh frozen plasma (FFP) or prothrombin complex concentrate (PCC). The dose of Vitamin K1 may be repeated as needed.

Anticoagulant | INR | Vitamin K1 orally | Vitamin K1 intravenously |
Warfarin | 5-9 | 1 to 2.5 mg for initial reversal 2 to 5 mg for rapid neutralization (additional dose of 1 to 2 mg if INR remains elevated after 24 hours) | 0.5 to 1 mg 0.5 to 1 mg |
>9 | 2.5 to 5 mg (up to 10 mg) | 1 mg | |
Acenocoumarol | 5-8 | 1 to 2 mg | 1 to 2 mg |
>8 | 3 to 5 mg | 1 to 2 mg | |
Fenprocoumon | 5-9 | 2 to 5 mg | 2 to 5 mg |
>9 | 2 to 5 mg | 2 to 5 mg | |

Hypoprothrombinemia due to other causes
In hypoprothrombinemia due to absorption disorders or treatment with antibiotics, salicylates, or sulfonamides, an oral or injectable dose of 2 mg of Konakion 10 mg/ml can be administered in adults. Konakion should be administered at the lowest effective dose.
The dose and route of administration will depend on the severity of the deficiency and the response to the medicine.
Elderly patients
Elderly patients tend to be more sensitive to the effect of this medicine. Therefore, the dose in this group should be at the lower limits of the recommended values. It has been shown that small doses of 0.5 to 1 mg of Vitamin K1 intravenously or orally effectively reduce the INR to <5 within 24 hours of administration.
Use in children
Children over 1 year of age
The doctor will decide the appropriate dose based on the indication and patient weight. 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 1 year of age
For this group of patients, due to the small dose required, Konakion 2 mg/0.2 ml pediatric should be used.
Normally, you will be administered Konakion as a single dose, but if your response is not sufficient, administrations may be repeated.
