At what age is it allowed to take?

In the annotation to "Phenibut" most manufacturers indicated that this tool does not apply to the treatment of patients younger than 3 years. Some companies note in contraindications the age of 8 years, since it is from that age that the dosage of 250 mg is indicated.

In practice, neurologists can prescribe such pills and younger children, but up to 2 years of age, they are prescribed extremely rarely, trying to avoid the harmful effects of the drug on the immature nervous system of babies.

The use of the drug in schoolchildren and adolescents without the advice of a specialist is not recommended.


"Phenibut" is not prescribed to children who have hypersensitivity to aminobutyric acid or any other ingredient of tablets. In the presence of lactose in the medication (this should be clarified in the annotation to the selected drug), the medicine is prohibited for patients with its shortage. Precautions in the treatment of "Phenibut" require children with ulcerative lesions of the gastrointestinal tract, as well as with liver disease, because the drug can irritate the gastric mucosa, and high doses of drugs are hepatotoxic.

Side effects

During the reception of "Phenibut", various negative reactions of the body may appear, for example: dizziness, nausea, skin rash or drowsiness. Very long-term use of the drug can adversely affect the state of the liver and hematopoiesis, therefore, with a long course of therapy, weekly monitoring of blood tests (the number of cells and the level of liver enzymes) is recommended.

If the children's body responded to the medication with any negative symptoms, you should stop giving the pills and consult a doctor.


To eliminate the harmful effect on the stomach, the medicine is taken after eating, swallowing the pill and washing it down with water. Patients of 3-8 years are recommended doses from 50 to 150 mg. In many cases, a child under eight years old "Phenibut" is prescribed 125 mg, that is, half a tablet at a time. A child of 8-14 years old is given a single dose of 250 mg (whole tablet). For adolescents older than 14 years, use adult doses of 250-500 mg per dose.

In such dosages, the medication should be taken three times a day, and the course of treatment often lasts 2-3 weeks. At children's age longer than 4 weeks, this medicine is not prescribed to eliminate addiction. Repeated reception of "Phenibut" is possible only after a break of 2-4 weeks. For the prevention of motion sickness, the drug is given in a dose of 250-500 mg one hour before the trip or when an indisposition occurs during the journey (but only at the first signs of motion sickness, since with the expressed symptoms "Phenibut" is ineffective).

When treating various neurological disorders, the medicine is given immediately in the dose prescribed by a neurologist, pediatrician or other specialist. There is no need to gradually increase the dosage at the beginning of treatment, but it is not advised to abolish the drug abruptly - the famous pediatrician Komarovsky also speaks about this. If you refuse to take immediately, you may experience negative symptoms, to eliminate which the child and began to give pills.

This is due to the mechanism of action of "Phenibut", because such a tool is a source of metabolites that during the period of therapy are not produced by brain cells. In the case of abrupt cessation of treatment, the nerve cells do not have time to undertake the task of synthesizing these metabolites immediately, which is manifested by the return of negative symptoms. With the gradual abolition of this does not happen, because brain cells adapt to change. That is why the doctor must prescribe a regimen of tablets with a decrease in dosage in the last week.


"Phenibut" refers to low-toxic drugs, cases of overdose of this drug have not been diagnosed until this time.In theory, a very high dose medication can cause nausea, dizziness, drowsiness, or vomiting. In such situations, it is recommended to wash the stomach and prescribe symptomatic remedies for the child.

If the medication is prescribed together with the specified means, the dosage should be below the standard.
