The instructions to neyromultivitu indicated that this drug during pregnancy is not recommended due to the limited experience of its use in pregnant women and the lack of data supporting the safety of his appointment to this patient population.
why pregnant women are not allowed to take Neyromultivit
neyromultivita The structure includes B vitamins B vitamins: the body useful helpers (B1, B6 and B12) in doses many times higher than the daily requirementin these persons, including pregnant women.The main effect of high doses of these vitamins is aimed at restoring normal metabolism Metabolism: The basis of life of all living in nerve cells (neurons).For example, vitamin B1 supplies the necessary energy for metabolism, vitamin B6 has been actively involved in the metabolism of amino acids from which proteins are built, and vitamin B12 has an overall beneficial effect on the function of the nervous system.All together they can significantly activate all kinds of metabolic processes
pregnancy - is a special condition in which the vitamins may even have a negative impact on the body.Therefore, in the first twelve weeks of pregnancy a woman can be appointed only physician folic acid Folic acid - the value is difficult to overestimate (it also refers to the B vitamins), which can prevent abnormal development.Vitamin and mineral supplements in this period of pregnancy are not appointed because that is laying the tissues and organs of the fetus, so any impact on a woman's body can be disastrous during this period.
Later, vitamin-mineral complexes are assigned, but only those which are intended for pregnant women, with a specially verified doses of vitamins.No one knows how a pregnant woman can act high doses of B vitamins as well as clinical trials of this kind were not carried out on pregnant women.
effect on the body of a pregnant woman of high doses of vitamins B1 and B6
Of the three vitamins that are part of neyromultivita,Vitamin B1 (thiamine) is the safest.The only drawback of this vitamin - it has a sufficiently pronounced allergenic properties, so it is not recommended for patients suffering from allergic diseases.During pregnancy, any allergic reaction can result in a catastrophe, so large doses of vitamin B1 is very dangerous.
Vitamin B6 (piridokin) can also cause allergic reactions.In addition, it is able to increase the acidity of gastric juice.As you know, many pregnant women are constantly worried about heartburn, with high doses of vitamin B6, it can repeatedly increase.It is dangerous to apply such high doses of vitamin B6 in gastric ulcer and duodenal ulcer even though the film covering the tablet, because it dissolves it in the duodenum.With careful use of pyridoxine and coronary heart disease Heart disease and heart attacks: that every woman should know and severe liver disease.During pregnancy, women are the liver carries a double burden, and no one knows how high doses of vitamin B6 will act on her body.
These recommendations relate to therapeutic doses of vitamins, their same dose in Neyromultivit ten times higher, respectively, higher than the risk of side effects.
effect on the body of a pregnant woman of high doses of vitamin B12
Vitamin B12 (cyanocobalamin) deserves special attention.One of the effects of its use (particularly in high dosage) is the activation of blood coagulation.Therefore, an immediate risk of increased blood clots in pregnancy that is totally unacceptable.
main concern of the obstetrician-gynecologist of female consultation is timely detection and treatment of all circulatory disorders in pregnant women, as they may affect the operation of the system mother - placenta - fetus.If for some reason the blood circulation in the system is broken, the fetus does not receive the nutrients and oxygen, which leads to a slowing of his physical development and, most importantly, a negative impact on the brain.
Very often the cause of such disorders of blood circulation is the formation of blood clots in the blood vessels of the placenta.In order to prevent this, pregnant women with disorders of the system mother - placenta - fetus (ie placental insufficiency) intravenously administered heparin - a substance that prevents blood clots.
Very high doses of vitamin B12 during pregnancy are dangerous because they can contribute to the formation of clots in blood vessels of the placenta.
Neyromultivit - a drug that was generally well tolerated, but the pregnancy - a special period during which not worth the risk and apply these vitamins in high doses.
