Phenibut is a well-known nootropic drug of systemic action, referring to psychostimulants with anxiolytic activity.
The main active ingredient is phenibut, also called aminophenyl butyric acid. It is a derivative of natural brain mediators, in particular GABA. GABA is needed by the central nervous system for metabolic processes and to maintain the efficient operation of all brain cells. The lack of this substance leads to various neurological diseases. Phenibut acts as a replacement therapy, restoring the necessary concentration of the mediator.
For the first time, Phenibut was synthesized by V. Perekalin in the center of experimental medicine back in the 1970s, and five years later the tranquilizer became widely used in medicine - they were even equipped with cosmonauts' pharmacy complexes.

Phenibut for babies and babies
Phenibut is a drug with low toxicity, mild action and minimal risk of side effects, so it can be used for the treatment of neurotic and anxiety disorders in children and the elderly. Quite a long period of time Phenibut is used in the treatment of tics, stuttering, urinary incontinence and neurosis in young children of preschool age. Moreover, the result of the combined use of Phenibut and special techniques or other medicines aimed at correcting the violation is good. Improvement is achieved in all children, and full recovery - in 65 - 95%, depending on the severity of the initial state. Phenibut in children is used in a dosage of 20-100 mg per day for 2-4 weeks. Longer use of the drug is not recommended so that the child does not develop psychological dependence on the pills.
Infants are not recommended to give Phenibut, because this drug can have a multidirectional effect on the child, which is impossible to predict in advance. Therefore, psychiatrists advise to refrain from using Phenibut for at least two years. If the child is hyperactive, mournful, mobile and suffers from other functional behavioral disorders, then other drugs should be used, the effects of which are more predictable and understandable both for the doctor and for the parents of the baby.
The recommended use of Phenibut for children described above in practice is practically not being complied with at the present time due to the peculiarities of diagnostics, perception and differentiation of the norm states and pathologies of the behavior of babies. In the countries of the former USSR, the practice of overdiagnosis of various neurological, mental and behavioral disorders in children, especially younger ones, has developed. This means that in clinics, children are diagnosed with a disease that they do not have, and begin treatment with potent drugs, including Phenibut. And if, with a truly existing disease, Phenibut will be effective and indicated, in the case of overdiagnosis, the drug will not bring the child anything except possible side effects, feelings of inferiority and possible exacerbation of psychological disorders.
Phenibut is most often prescribed for hyperactivity, constant hysteria and neurosis, and the diagnosis is made on the basis of a simple examination of the child and from the words of the mother. That is, there is an exclusively subjective perception of the child’s behavior, which is evaluated from the position of the mother’s and the doctor’s views as “right” or “wrong”. And if the child’s behavior is assessed as improper, then he is given a clinical diagnosis and begins treatment with Phenibut or another nootropic drug, for example, Fenotropil. Meanwhile, such a diagnosis by a neurologist or psychiatrist is unacceptable, since this is a profanation of medical science. Any neurological or psychiatric diagnosis is made only on the basis of objective results of tests, examinations, examinations and conversations with the child, as well as monitoring him in various situations. If during all these examinations the doctor reveals really existing violations, then only in this case can he make an appropriate diagnosis.
If tests and conversations were not conducted, then the child cannot be diagnosed only from the words of the mother, who seems to be crying not so much, screaming a lot, having hysterics, etc. After all, there are no objective data for the presence of the disease, but there are only observations of the mother, which are at odds with the ideas that have formed in her head about how the child should behave and react to various stimuli. When, on the basis of such complaints of the mother, the doctor makes a clinical diagnosis to the child, it is precisely overdiagnosis that takes place. Remember that even mental disorders are strictly classified and there are special tests and methods for their detection that exclude the subjectivity of the doctor’s perception, and not just the mother’s observation of her child’s behavior. Therefore, Phenibut should not be used for young children if there are no violations confirmed by surveys.
In most cases, children do not have severe disorders that are the clinical diagnosis. Usually, the child suffers from a behavioral disorder or mental reactions that are adjusted by the correct behavior of the parent. In such situations, the use of tinctures valerian or motherwort is enough to calm the child. However, to normalize the child's behavior, parents will have to work, changing their behavior and habits, as well as carefully controlling their actions.
Returning to Phenibut, it can be said that the drug is often prescribed for the treatment of non-existent pathologies identified during “overdiagnosis”. However, such use of medication cannot be considered correct and justified; therefore, all recommendations remain on the conscience of the particular doctor and parents of the child.
According to the annotation to the drug, the list of contraindications is as follows:
- individual intolerance to Phenibut or any of the excipients;

Since Phenibut is a low-toxic compound, only prolonged use of it in doses substantially higher than therapeutic (from 7 to 14 g per day) can provoke the development of hepatotoxic effects.
In particular, the patient increases in excess of the physiological norm the number of eosinophils in the peripheral blood, and also steatosis (fatty infiltration) of the liver may develop - a chronic disease caused by the accumulation in the liver tissues of a large amount of triglycerides and characterized by fatty degeneration of the organ cells.
With prolonged use, it is necessary to evaluate the blood and liver.
Phenibut is usually taken in two to three weeks and then repeated after the same amount of time. However, the severity of symptoms and the nature of the disease can cause a lengthening of the course or an increase in a single dose.

We offer to read the reviews of people who used Phenibut:
- Nice Phenibut took Baltic production in depressive disorder. Has passed two medical courses for a month each. I liked the effect, the mood improves, there is no clouding in the head, as when taking other prescription tranquilizers and antidepressants.
