Vitamin K is a fat-soluble vitamin which is essential for blood clotting. It also plays a role in bone health.

Des lack of vitamin K can lead to unwanted bleeding. Most people can get sufficient vitamin K from the food they eat. It occurs naturally in many foods, especially green leafy vegetables such as cabbage and spinach, green peas and beans, watercress, asparagus, broccoli, oats and whole wheat. Menadiol sodium phosphate is an alternative form of vitamin K for people who are unable to absorb sufficient vitamin K from their diet because of difficulties absorbing fatty substances. It is a man-made, water-soluble form of vitamin K which can help prevent deficiency.

To make sure that this is the right treatment for you, before you start taking the tablets it is important that your doctor or pharmacist knows:

  • If you have been told you have either vitamin E deficiency or glucose-6-phosphate dehydrogenase (G6PD) deficiency (this is an inherited disorder which causes problems after eating foods such as fava beans).

  • If you are pregnant or breastfeeding. This is because you may need to stop taking menadiol sodium phosphate towards the end of your pregnancy.

  • Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.

  • Si vous avez déjà eu une réaction allergique à un médicament.

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside your pack. It will give you more information about the tablets.

  • Take menadiol sodium phosphate exactly as your doctor tells you to. Your dose will be adjusted to suit you, but it is usual for an adult to take 1-4 tablets daily. Your doctor will tell you what the right dose is for you, and this information will also be printed on the label of the pack of tablets to remind you about what the doctor said to you.

  • You can take the tablet at whatever time of day you find easiest to remember, but try to take your doses at the same time of day, each day. You can take the tablet either before or after a meal.

  • If you forget to take a dose at your usual time, take it as soon as you remember. If you do not remember until the following day then leave out the missed dose - do not take two doses together to make up for a forgotten dose.

  • Essayez de respecter vos rendez-vous réguliers avec votre médecin. Cela permet à votre médecin de suivre vos progrès.

Menadiol sodium phosphate is unlikely to cause any unwanted side-effects. Very occasionally, there can be a problem with red blood cells which can lead to anaemia or jaundice. Although this happens only rarely, if you develop any yellowing of your skin or the whites of your eyes, or if you think you may be anaemic, you should tell your doctor.

Si vous ressentez d'autres symptômes que vous pensez être dus aux comprimés, veuillez consulter votre médecin ou votre pharmacien pour obtenir des conseils supplémentaires.

  • Gardez tous les médicaments hors de la portée et de la vue des enfants.
