1. What Konakion 10 mg/ml is and what it is used for
Konakion contains phytomenadione (Vitamin K) as the active substance, which plays a role in the blood coagulation mechanism. A deficiency of vitamin K1 leads to an increased tendency to bleed.
It is used for the treatment and prevention of bleeding (haemorrhage).
Konakion 10 mg/ml is indicated for:
The prevention and treatment of hypoprothrombinemia (lack of a substance called prothrombin, which is necessary for blood to clot) due to vitamin K deficiency.
Therefore, it is indicated in haemorrhage or risk of haemorrhage due to severe hypoprothrombinemia caused by:
- Overdose of coumarin-derived anticoagulant medicines in patients taking them (medicines that prevent the formation of blood clots)
- Vitamin K deficiency (hypovitaminosis K) caused by factors that reduce the absorption or synthesis of vitamin K, such as obstructive jaundice (a disorder of bile secretion into 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 haemorrhagic disease of the newborn, Konakion 2 mg/0.2 ml paediatric formulation is used.
2. What you need to know before using Konakion 10 mg/ml
Do not use Konakion
- If you are allergic to phytomenadione or to any of the other components of this medicine (listed in section 6)
- It must not be administered intramuscularly if you are being treated with anticoagulants, as this route may interfere with anticoagulant therapy. In addition, intramuscular injections carry a risk of causing hematomas (bruising) if you are receiving anticoagulant treatment.
Warnings and precautions
Talk to your doctor before starting to use Konakion 10 mg/ml.
- If you have severe liver disease, make sure your doctor is aware, as they may recommend blood tests to monitor certain parameters during your treatment
- If you have other diseases
- If you have allergies
Children
For newborns and children under 1 year of age, another product of the same brand but with a lower dose should be used: Konakion 2 mg/0.2 ml paediatric.
Use of Konakion 10 mg/ml with other medicines
Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.
This is very important, as using several medicines at the same time may increase or decrease their effects.
The following medicines may interact with Konakion:
Anticoagulants such as warfarin or acenocoumarol (medicines that help prevent blood clots from forming)
Medicines for epilepsy.
Pregnancy, breastfeeding and fertility
- If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor before using this medicine.
- Pregnancy
- Konakion may be administered during pregnancy if the benefit to the mother outweighs the risk to the fetus.
- Breastfeeding
- You may be treated with Konakion while breastfeeding.
Administration of Konakion for the prevention of haemorrhagic disease of the newborn is not recommended in women who are in an advanced stage of pregnancy or who are breastfeeding.
Driving and use of machines
The influence of Konakion on the ability to drive or operate machinery is none or negligible.
Konakion 10 mg/ml contains sodium hydroxide
This medicine contains less than 23 mg (1 mmol) of sodium per ampoule and is therefore considered essentially "sodium-free".
3. How to use Konakion 10 mg/ml
Follow exactly the administration instructions for this medicine as given by your doctor. If in doubt, consult your doctor or pharmacist again. Depending on the nature of your illness, your doctor will administer the correct dose of this medicine.
The route of administration will depend on the severity of your illness and the risks associated with each route. Konakion 10 mg/ml can be administered orally or intravenously; intravenous administration may be indicated when the oral route is not feasible or effective.
Usual dose for adults
Severe or very severe bleeding, e.g., during anticoagulant therapy:
After discontinuation of the coumarin anticoagulant treatment you are taking, a dose of 5–10 mg of Konakion will be administered slowly (over at least 30 seconds) intravenously, together with fresh frozen plasma (FFP) or prothrombin complex concentrate (PCC). The vitamin K1 dose may be repeated as many times as necessary.

Hypoprothrombinemia due to other causes
In hypoprothrombinemia due to malabsorption disorders or treatment with antibiotics, salicylates, or sulfonamides, an oral dose preferably or an injectable dose of 2 mg of Konakion 10 mg/ml may 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 medication.
Elderly patients
Elderly patients tend to be more sensitive to the effects of this medication. Therefore, the dose in this group should be at the lower end of the recommended range. Small doses of 0.5 to 1 mg of vitamin K1 administered intravenously or orally have been shown to effectively reduce INR to <5 within 24 hours after administration.
Use in children
Children over one year of age
The physician will determine the appropriate dose based on the indication and patient's weight. A single dose corresponding to one-tenth of the total intravenous adult dose of vitamin K1 has been reported to be effective in reversing asymptomatic INR elevations (>8) in clinically stable children.
Newborns and children under one year of age
For this patient group, due to the small dose required, Konakion 2 mg/0.2 ml pediatric formulation should be used.
Konakion is normally administered as a single dose; however, if the response is insufficient, additional doses may be given.
Instructions for correct administration of the preparation
The Konakion solution must be clear (clean) at the time of use. If ampoules have not been stored properly, they may appear cloudy or show phase separation. In such cases, the ampoule must be discarded.
Oral route: Konakion can be administered using a syringe as follows: Break the neck of the ampoule and withdraw the required amount using a syringe with a needle. Remove the needle from the syringe and administer the contents of the syringe directly into the patient's mouth. Rinse the syringe with liquid.
Parenteral route: Konakion must not be diluted or mixed with other parenteral medications, but it may be injected into the lower part of an infusion set.
If you use more Konakion 10 mg/ml than you should
Cases of vitamin K1 (phytomenadione) overdose are unknown. The ability to reinitiate anticoagulant therapy may be affected.
In case of overdose or accidental ingestion, contact your physician or pharmacist immediately, go to a medical center, or call the Toxicology Information Service at telephone number 91 562.04.20, indicating the medication and the amount administered.
