Betaserk not used during pregnancy because of the fact that its impact on the fetus of pregnant women and is not currently understood. A pregnancy is known - is a condition in which sometimes even the most studied and seemingly safe medicines can have adverse effects on the fetus.
What are the characteristics of action betaserk
Active ingredient betaserk
Betaserk - a drug that helps restore the balance
betahistine is - a synthetic analogue of histamine. Action betaserk associated with reduced frequency and intensity of vertigo, decrease tinnitus, hearing improvement in case of downgrade. Assign this medication at vestibular vertigo
Dizziness - if the ground is slipping from under his feet
, Disease and Meniere's syndrome and other syndromes with dizziness, headache, tinnitus, hearing loss, nausea, vomiting.
The mechanism of action betaserk associated with mild activation of histamine H1 receptors located in peripheral tissues and inhibition of H3-retskeptorov gistamiina located in the medulla oblongata. As a result, activation of H1-retsaptorov widen the blood vessels that supply blood to the neck and head. In more betaserk enhances small capillaries in the inner ear and particularly of the labyrinth. This leads to an improvement in the function of the body, reduce imbalances and improve hearing.
Inhibition of H3 receptor leads to disruption of the conduction of nerve impulses in the center of balance - it actively suppresses these unpleasant sensations as dizziness, nausea, vomiting.
What is in pregnancy may need betaserk
Pregnancy is often accompanied by symptoms such as dizziness, nausea and vomiting. However, the origin of these symptoms are generally not associated with dysfunction of the organ of equilibrium. Dizziness during pregnancy is often associated with autonomic disorders of the cardiovascular system.
The autonomic nervous system (ANS) is actively working on the smooth muscles of internal organs and blood vessel walls and is divided into two divisions - the sympathetic and parasympathetic nervous system (PNS SNA). Action PNS prevails at rest, while the SNA "turned on" during times of stress, when faced with danger, and so on.
Blood vessels dilate under the influence of the PNS, this can result in reduced blood pressure and dizziness. Nervous tension (as is well known, during pregnancy a woman is nervous often, and sometimes for no reason) helps connect SNA - it causes constriction of blood vessels. Such sudden changes in the condition of the blood vessels and cause discomfort - headaches, dizziness, nausea. They are amplified against the backdrop of intoxication developing in the first half of pregnancy toxemia.
In the second half of pregnancy a woman can lie in wait for such a danger as preeclampsia - a dramatic expansion of numerous capillaries, stagnation in their blood, swelling of the kidneys, high blood pressure. This may also be dizziness, associated this time with high blood pressure
Blood pressure - dangerous if his swing?
Can betaserk help pregnant woman
Dizziness pregnant women are not usually associated with the pathology of the center of balance. Although the autonomic disorders, which can be during pregnancy, possible including functional disorders of the inner ear. It is even possible that the inhibition of nerve impulses in the center of balance (inhibition of H3 receptors in the central nervous system) in the medulla oblongata could remove or significantly reduce dizziness.
But the action betaserk a pregnant woman and the fetus has not been studied, and therefore no one knows how it will be effective in this case. Furthermore, it is absolutely unclear what kind of effects of this drug will have on the autonomic nervous system of women and, consequently, its blood vessels and internal organs.
It is also unknown whether betaserk have some negative effects on the fetus. While in the process of laboratory animals teratogenic and mutagenic betaserk on the fetus has not been revealed, it does not exclude the indirect effects of the drug on the fetus by affecting the blood vessels. That is why betaserk during pregnancy does not apply.
Betaserk has few side effects, however, they are found. The most common causes side betaserk on the part of the digestive system - nausea, vomiting, bloating, discomfort and sometimes mild abdominal pain

. All these unpleasant sensations in pregnant women occur without betaserk, it can also strengthen them. A side effect of betaseka are also headaches and allergic reactions - they can also strengthen the already difficult state of the pregnant woman.
Betaserk - a drug that can not be used during pregnancy, especially without a doctor's prescription.
