1. what konakion mm is and what it is used for

Konakion MM contains a medicine called phytomenadione. This is a man-made vitamin called vitamin K1. Konakion MM is used for the following:

• To prevent and treat bleeding after the use of certain medicines to thin the blood (called anti-coagulants).
• To treat children (aged 1 year and older) who have liver disease or low levels of vitamin K intheirbody because of illness. Konakion MM is normally used to treat these children after advice from a specialist haematologist (blood doctor).

Konakion MM works by helping your body make blood clotting factors. These blood clotting factors help stop bleeding.

Therapeutic indication

Konakion MM is indicated as an antidote to anticoagulant drugs of the coumarin type in the treatment of haemorrhage or threatened haemorrhage, associated with a low blood level of prothrombin or factor VII.

Posology and method of administration Konakion MM Ampoules 10 mg/ml is for intravenous injection.

Severe or life-threatening haemorrhage , e.g. during anticoagulant therapy: The coumarin anticoagulant should be withdrawn and an intravenous injection ofKonakion MM given slowly (over at least 30 seconds) at a dose of 5–10 mg together with prothrombin complex concentrate (PCC). Fresh frozen plasma (FFP) may be usedifPCC is not available. The patient’s INR should be estimated three hours later and, if the response has been inadequate, the dose should be repeated. Not more than 40 mg ofKonakion Mm should be given intravenously in 24 hours. Coagulation profiles must be monitored on a daily basis until these have returned to acceptable levels; in severe cases more frequent monitoring is necessary.

For full details of dose recommendations for vitamin K 1 therapy in patients with major and life-threatening bleeding, please refer to the Summary ofProduct Characteristics.

Less severe haemorrhage: An intravenous injection ofKonakion MM given slowly at a dose of 0.5 – 1 mg. For full details of dose recommendations for vitamin K1 therapy in patients with asymptomatic high International Normalised Ratio (INR) with or without mild haemorrhage, please refer to the Summary of Product Characteristics.

Reversal of anticoagulation prior to surgery: For emergency surgery that can be delayed for 6–12 hours, 5 mg intravenous vitamin K1 canbe given. If surgery cannot be delayed, PCC can be given in addition to intravenous vitamin K1 and the INR checked before surgery.

Use with anticoagulants other than warfarin : The dosing recommendations above apply to patients taking warfarin. There are limited data regarding reversal of the effects of other anticoagulants, such as acenocoumarol or phenprocoumon. The half lives of these anticoagulants are different to warfarin and different doses of vitamin K1 may be required.

Elderly

Elderly patients tend to be more sensitive to reversal of anticoagulation with Konakion MM; dosage in this group should be at the lower end of the ranges recommended.

Children aged 1 to 18 years

It is advisable that a haematologist is consulted about appropriate investigation and treatment in any child in whom Konakion MM is being considered.

For patients on warfarin therapy, therapeutic intervention must take into consideration the reason for the child being on warfarin and whether or not anticoagulant therapy has to be continued (e.g. in a child with mechanical heart valve or repeated thromboembolic complications) as vitamin K administration is likely to interfere with anticoagulation with warfarin for2–3 weeks.

It should be noted that the earliest effect seen with vitamin K treatment isat4–6 hours and therefore in patients with severe haemorrhage replacement with coagulation factors may be indicated (discuss with haematologist).

Dose of vitamin K

There are few data available regarding use of Konakion MM in children over 1 year. There have been no dose ranging studies in children with haemorrhage. The optimal dose should therefore be decided by the treating physician according to the indication, clinical situation and weight of the patient. Suggested dosages based on clinical experience are as follows:

Children with major and life-threatening bleeding: a dose of 5 mg vitamin K, i.v. is suggested (together with PCC if appropriate, or FFP ifPCC is not available).

Children with asymptomatic high International Normalised Ratio (INR) with or without mild haemorrhage: i.v. vitamin K, at doses of 30 micrograms/kg have been reported to be effective in reversing asymptomatic high (>8) INR in clinically well children.

INR should be measured 2to6 hours later and if the response has not been adequate, the dose may be repeated. Frequent monitoring of vitamin K dependent clotting factors is essential in these patients.

Neonates and babies

Konakion MM Paediatric 2 mg/0.2 ml should be used in these patients.
