Magnesium and vitamin B6 are very important elements that take an active part in many biochemical processes in the human body. This complex is prescribed by obstetricians and gynecologists to those pregnant women whose uterus is in increased tone and there is a risk of miscarriage.

Why is magnesium B6 needed during pregnancy?

Magnesium is considered to be one of the most important macroelements in the body of a pregnant woman. It takes part in more than 200 biochemical processes. Magnesium and vitamin B6 help control the process of transferring genetic memory from the mother to the child. Magnesium also relaxes muscles, reduces excitability (if it is increased), and calms the nervous system. It should be remembered that the child needs vitamins and macroelements no less than his mother, so during pregnancy it is often necessary to fortify your diet, take special vitamin and mineral supplements.

If a pregnant woman is diagnosed with magnesium and vitamin B6 deficiency, she will experience the following symptoms:

  1. Bad dream.
  2. Nausea.
  3. Frequent fatigue.
  4. Nervousness and unreasonable irritability.
  5. Constipation.
  6. A tingling sensation in the chest area.
  7. The appearance of convulsions.

In some cases, a gynecologist may prescribe this macronutrient to women who experience tachycardia, hypertension, and heart problems during pregnancy.

Is magnesium B6 harmful during pregnancy?

Despite the fact that magnesium has no contraindications and cannot cause significant harm to the health of the expectant mother if taken according to the instructions, it is best to consult with your doctor whether you need to take magnesium B6 or not. The fact is that a deficiency of magnesium and vitamin B6 in the blood of a pregnant woman can only be determined by laboratory testing. During pregnancy, special scheduled tests are prescribed to determine the level of these substances.

Indications magnesium B6 during pregnancy

The main indication for prescribing magnesium B6 to an expectant mother is a lack of magnesium and vitamin B6 in the woman's body, which is manifested by the development of skin and hair pathologies, changes in muscle tone, miscarriage or premature birth.

Therefore, as soon as a pregnant woman begins to experience the symptoms listed above, she must immediately consult a doctor.

Release form

Magnesium B6 Forte

The medicine based on the active components magnesium citrate and pyridoxine hydrochloride helps to replenish the deficiency of magnesium and vitamin B6 in the body. If after a month of taking these tablets the patient's main symptoms of deficiency of these substances (irritability, fatigue, insomnia, stomach cramps, palpitations) do not disappear, the treatment is considered inappropriate.

The dosage is determined individually, based on the established level of magnesium and vitamin B6 in the blood. If a pregnant woman has been diagnosed with phenylketonuria, kidney dysfunction, allergy to magnesium or pyridoxine, hereditary galactosemia, taking magnesium B6 Forte is prohibited. Do not use simultaneously with levopoda.

Taking Magnesium B6 Forte in some cases can cause diarrhea, pain in the abdomen, flatulence, nausea, and allergies.

Magnesium B6 Evalar

A medicine based on the active components of magnesium asparaginate with vitamin B6. Magnesium asparaginate or bioavailable organic magnesium salt is tolerated by the body of a pregnant woman quite well. At the same time, no side effects from the intestines or stomach are observed. Pyridoxine hydrochloride (vitamin B6) helps to enhance the effect of magnesium and improves its absorption.

It is recommended to take Magnesium B6 Evalar one tablet during meals, with a sufficient amount of liquid. The therapy lasts about one month, but it can be continued or repeated if necessary.

Motherwort Forte with Magnesium B6

A medicine based on the active components of motherwort extract, magnesium carbonate and vitamin B6. It has anticonvulsant, sedative, diuretic and cardiotonic effects.

The dosage is individual and is determined by the attending physician. As a rule, no more than two tablets are taken per day during meals, with a sufficient amount of liquid. Patients who have been diagnosed with a stomach ulcer, an allergy to the components of the drug, or erosive gastritis in the acute stage are prohibited from taking this drug.

Pharmacodynamics

Let us consider the pharmacodynamics and pharmacokinetics of drugs based on magnesium B6 during pregnancy using the example of “Magnesium B6 Forte”.

Magnesium is considered a vital macronutrient that plays an active role in cell function and metabolism.

For example, it helps regulate muscle contraction and the conduction of nerve impulses to them. Most of the magnesium in the human body is found in bone tissue. Magnesium deficiency during pregnancy is quite common. This is due to poor nutrition, heredity, and the fact that the fetus takes some of the mineral.

Vitamin B6 or pyridoxine hydrochloride, which is also found in these tablets, takes an active part in improving the penetration of magnesium into cells.

Pharmacokinetics

Magnesium salts are partially passively absorbed in the gastrointestinal tract (the level of such absorption is 50%). Magnesium B6 is excreted through the kidneys.

Dosing and administration

Magnesium B6 for uterine tone during pregnancy

Hypertonicity of the uterus during pregnancy is one of the indications for prescribing magnesium B6. Most often, this symptom occurs in the first trimester of pregnancy. Hypertonicity is characterized by the fact that the woman's uterus is too tense, which significantly increases the risk of miscarriage. Magnesium helps to reduce the tone of the uterus, thereby protecting the woman from the undesirable consequences of its deficiency.

Irritability, extreme fatigue, nervousness, stress and depression have a strong effect on muscle tone during pregnancy. Spasms can occur in all muscles, including the uterus. To improve the condition of a pregnant woman, gynecologists often recommend taking Magnesium B6.

Magnesium B6 for edema during pregnancy

Edemas often occur during pregnancy, particularly in the second half. In this case, a woman experiences the following unpleasant symptoms:

  1. Numbness in the hands.
  2. Heaviness in the legs.
  3. Rings and shoes start to pinch and rub.
  4. If you press your fingers on the area of swelling, a “pit” will form in that place, which will take a long time to go away.
  5. The skin becomes pale and too smooth.

There are many reasons for swelling during pregnancy. Most often, swelling in the legs is caused by the rapidly growing uterus, which begins to press on neighboring organs. Such swelling is considered physiological and does not pose any danger to the woman or her future child.

But in some cases, edema may occur for more serious reasons. For example, this category of etiological factors may include improper functioning of the kidneys, liver or heart. An important component of the therapy for such edema is strengthening the vascular wall of the arteries and veins. For this purpose, doctors recommend taking magnesium B6.

Use magnesium B6 during pregnancy during pregnancy

How much magnesium B6 can you drink during pregnancy?

The duration of taking magnesium and pyridoxine hydrochloride-based drugs can only be determined by the attending physician, based on the level of magnesium in the pregnant woman's blood, the tone of her uterus, and the general condition of the body. As a rule, magnesium B6 is prescribed for a period of two weeks to one month. But if necessary, this period can be extended.

Magnesium B6 during early pregnancy

In early pregnancy, taking magnesium B6 is an important step towards normal bearing of a healthy child. It is during this period that magnesium deficiency can lead to hypertonicity of the uterus, which is the main cause of miscarriage. Magnesium B6 is often prescribed starting from the first weeks of pregnancy, especially if the woman has had a previous miscarriage.

Allergy to magnesium B6 during pregnancy

Most doctors are of the opinion that allergic reactions to magnesium B6 develop extremely rarely. In some cases, in particular, if the patient takes a concentrated form of this macronutrient or injects it intramuscularly, reactions very similar to allergic reactions may be observed.

The main symptoms of magnesium B6 allergy during pregnancy are the following:

  1. Nausea.
  2. Vomit.
  3. Rash.

Magne B6 or Magnelis during pregnancy?

Both drugs belong to the pharmacological group of medicines that consist of a combination of mineral and vitamin B6. The main difference between these two drugs is their price. Magnelis is a Russian-made drug, so the cost of this drug is significantly lower.

The only difference is the soluble form of these two products. Soluble Magne B6 contains 100 mg of magnesium and twice as much vitamin B6 as in tablets. But before buying any of these products during pregnancy, first consult with your doctor.
