Menadione

Menadione / Vitamin K3

Vitamins are a type of compound that is necessary for people to have for health purposes and to grow. However, they are usually only needed in relatively small amounts and can usually be found in foods that are eaten all the time. Vitamin K is a type of compound that is required in order to make sure the blood clots as it normally should.

Some of the foods can vitamin K can be found in include dairy products, meat and green leafy vegetables, such as spinach. All of the vitamin K that is necessary to have in a day can be found provided a person regularly eats a balanced diet that includes those foods in it. Vitamin K does not significantly die out when foods are cooked ordinarily.
Menadione Side Effects
In the event that a person is taking a blood thinner, or an anticoagulant medication, the amount of vitamin K that is present in the diet may have a tendency to affect how well the medications function for their served purpose. For this reason, the doctor may wish to change the course of the diet so that the medicines may work better or more effectively.

It is rare for a person to experience a lack of vitamin K, but in the event that a person does, they will likely experience problems with the clotting of their blood and they will likely experience more bleeding. For the purposes of treatment in this case, the doctor may prescribe that vitamin K be taken. The medicine is only available in this way, by way of a prescription from a doctor. It is also only available in either a capsule form or a tablet form. Sometimes, vitamin K will often be given to a newborn infant so that they do not experience any kind of problems with bleeding.

Anybody who is presently taking a dietary supplement and does not have a prescription for it would do well to carefully read the precautions on the label and follow them to the fullest extent. For such supplements, all of the following should be kept in mind:

Allergies

Make sure to tell the doctor in the event that there has ever been any kind of allergic or unusual reaction to the medicines that are labeled in the group or to any other kind of medicine. Make sure to tell the qualified health care professional if any other kinds of allergies exist as well, such as to animals, preservatives, foods or dyes. Always read the package ingredients and the label on a non-prescription product with the utmost care.

Pediatric

Children are prone to being especially sensitive to vitamin K and its potential effects, particularly having high dosages of phytonadione or menadiol. Because of this, there is the possibility of a higher risk of side effects during a treatment of vitamin K. Likewise, newborns, and especially babies that were born prematurely, are likely to be even more sensitive to the effects of vitamin K than children that are older are.

Geriatric

There are numerous medications that have not fully been tested, if at all, in elderly people. For this reason, it is not necessarily known that the medications will work in the same fashion as they do in adults of a younger age, or if they may cause a different kind of side effect or any other problems in those who are of an older age. There is currently no specific information with regards to using vitamin K for the elderly.

Pregnancy

There have been no reports involving vitamin K with relation to birth defects or any other problems found in humans. However, it has been reported to cause some troubles for a baby, such as jaundice, so it is not recommend for women who are pregnant to take any kind of supplementation for vitamin K throughout the duration of their pregnancy.

Breastfeeding

There have been no reports of nursed babies being affected by vitamin K supplements being taken by a breastfeeding mother. It is important to discuss how to give a child supplements if they are being given a formula that is unfortified. In these cases, the baby is required to obtain their vitamins in another way.

Drug interactions

There are some medicines that should not be use during or near the time that a person eats food or eats a certain kind of food due to the potential interactions that may occur. It is also possible for interactions with medicines to occur when taking them with alcohol or tobacco.
