Uses for Mephyton

Vitamins are compounds that you must have for growth and health. They are needed in only small amounts and usually are available in the foods that you eat. Vitamin K is necessary for normal clotting of the blood.

Vitamin K is found in various foods including green leafy vegetables, meat, and dairy products. If you eat a balanced diet containing these foods, you should be getting all the vitamin K you need. Little vitamin K is lost from foods with ordinary cooking.

If you are taking anticoagulant medicine (blood thinners), the amount of vitamin K in your diet may affect how well these medicines work. Your doctor or health care professional may recommend changes in your diet to help these medicines work better.

Lack of vitamin K is rare but may lead to problems with blood clotting and increased bleeding. Your doctor may treat this by prescribing vitamin K for you.

Vitamin K is routinely given to newborn infants to prevent bleeding problems.

This medicine is available only with your doctor's prescription.

Before using Mephyton

If you are taking a dietary supplement without a prescription, carefully read and follow any precautions on the label. For these supplements, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Children may be especially sensitive to the effects of vitamin K, especially menadiol or high doses of phytonadione. This may increase the chance of side effects during treatment. Newborns, especially premature babies, may be more sensitive to these effects than older children.

Geriatric

Many medicines have not been tested in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information about the use of vitamin K in the elderly.

Pregnancy

Vitamin K has not been reported to cause birth defects or other problems in humans. However, the use of vitamin K supplements during pregnancy is not recommended because it has been reported to cause jaundice and other problems in the baby.

Breastfeeding

Vitamin K taken by the mother has not been reported to cause problems in nursing babies. You should check with your doctor if you are giving your baby an unfortified formula. In that case, the baby must get the vitamins needed some other way.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together...
