It is possible to reboot the psyche and put the emotional background in order if you resort to the right therapy in time. An excellent solution for impaired cognitive functions and neuropathic disorders is phenibut. Modern and foreign neurologists actively use it in their practice. But when using the medicine, some nuances should be taken into account.
Indications for the drug Phenibut
asthenic and anxiety-neurotic conditions;
worry, anxiety, fear;
insomnia;
as a sedative before surgery;
Meniere's disease;
dizziness associated with dysfunction of the vestibular apparatus;
prevention of motion sickness;
stuttering and tics in children.
There is evidence of an increase in the effect of antiparkinsonian drugs under the influence of phenibut (due to the presence of a dopamine-positive component in the drug).
What's happened?
This drug is a mild and effective nootropic that also has an anxiolytic effect on the body. Phenibut was synthesized at the Leningrad Pedagogical Institute in the 60s of the last century. The powerful therapeutic effect of the drug was appreciated in practice, as a result of which phenibut became a permanent medicine in the astronauts’ medicine cabinet.
If you take the drug correctly, avoiding uncontrolled use and the maximum permissible dosage, you can get rid of a number of disorders:
- chronic fatigue and weakness;
- increased anxiety;
- causeless anxiety;
- memory loss and decreased concentration;
- manifestations of insomnia.
The effective drug Phenibut is available in pharmacies with a prescription. And there are reasons for this.

Indications for use
Is Phenibut available from pharmacies with or without a prescription? It is sold in retail pharmaceutical chains only as prescribed by a doctor. But if you really need it, subject to the rules of administration, it can be purchased without a prescription on the website of a sports nutrition store.
A course of use of the medicine, subject to the dosage specified in the prescription and annotation, will improve your health and relieve diseases:
- Insomnia. The drug affects the parts of the brain that respond to the production of melatonin, the sleep hormone. As a result, the amount of this substance returns to normal, which allows you to maintain normal sleep and rest patterns.
- Instability of the emotional background. Increased anxiety, depression, and stress are associated with insufficient production of the hormone responsible for mood. A prescription for this drug and treatment can improve the patient’s condition by rebooting his psyche.
Why is Phenibut a prescription? So that people do not use it for other purposes. But when taken correctly, the drug, classified as a dietary supplement, helps improve the patient’s condition.
How to get a prescription for Phenibut?
From 2022, the drug is sold by prescription. Although before this it could be freely purchased in a retail network, bypassing the doctor’s office in order to obtain a document for the sale of the drug.
How to get a prescription for Phenibut? To do this, just contact a neurologist or psychiatrist. The specialist will conduct a study of the body and, if necessary, prescribe phenibut as part of mono- or complex therapy.
In this case, the recipe must contain the following information:
- Patient's personal information. This category of information required for dispensing phenibut includes last name, first name, patronymic, age and diagnosis.
- Dosage and order of administration. When selling, the pharmacist must clearly know how much phenibut to dispense so that the patient has enough for the course of treatment.
The prescription is certified by the seal of the institution, the personal stamp of the doctor. If it is necessary to repeat the course of treatment, you will need to obtain permission to dispense the medication from the pharmacy again.
At the same time, it is noteworthy that in Europe phenibut is not considered a medicine. The European Union health authorities classify it as a dietary supplement, considering it a necessary component of sports nutrition. Taking this nuance into account, phenibut from SNS Smart Powders is available in sports nutrition stores without a prescription.
Reasons for sales in pharmacies for their intended purpose
Why is Phenibut sold by prescription? There are several reasons for this:
- Addiction.
If the patient independently prescribes and discontinues this medicine, then with such a spontaneous approach it can harm the body. Phenibut is addictive, making it difficult for a person to stop taking it in the future. At the same time, the medicine affects internal organs and systems, which can cause unwanted reactions.
- Exceeding the dosage.
Every third patient, in order to improve the result, seeks to take the drug in larger quantities than stated in the annotation for it. As a result, if the specified dose is exceeded, he experiences a state close to drug intoxication. Teenagers seeking thrills and a state of euphoria are increasingly resorting to this method. Why is Phenibut sold by prescription? So as not to harm the growing body.
This drug belongs to the category of proven and effective drugs that have a minimal set of side effects on the human body when used correctly. But due to the fact that most patients use the medicine for other purposes or exceed the dosage, the Ministry of Health decided to sell it by prescription.
