None.

Large doses of menadiol sodium diphosphate may decrease patient sensitivity to anticoagulants.

There is evidence of hazard if menadiol sodium diphosphate is used in human pregnancy. It is known to be associated with a small risk of haemolytic anaemia, hyperbilirubinaemia and kernicterus in the infant if administered to the mother in late pregnancy or during labour. Menadiol sodium diphosphate is therefore contra-indicated during late pregnancy.

None known.

Menadiol sodium diphosphate may induce haemolysis (especially in the newborn infant) in the presence of erythrocyte glucose-6-phosphate dehydrogenase deficiency or low concentrations of alpha-tocopherol in the blood.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

No information is available.

Menadiol sodium diphosphate is a water-soluble vitamin K analogue. The presence of vitamin K is essential for the formation within the body of prothrombin, factor VII, factor IX and factor X. Lack of vitamin K leads to increased tendency to haemorrhage.

Menadione is absorbed from the gastro-intestinal tract without being dependent upon the presence of bile salts. Vitamin K is rapidly metabolised and excreted by the body.

There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
