Phenibut® has both nootropic and anxiolytic properties. It eliminates tension, anxiety, and fear as well as improves sleep. The drug lengthens the latent period and shortens the duration and severity of nystagmus, and has an anti-epileptic effect.
Phenibut diminishes asthenia and vasovegetative symptoms, including headache, “heavy head” feeling, sleep disturbances, irritability, and emotional lability. At the same time, it increases mental performance and improves psychological indicators: attention, memory, speed, and accuracy of sensory-motor reactions.
Phenibut onset of action: Starting from the first days of therapy patients notice that they feel healthier, show more interest and initiative and feel more motivation for action.
After severe craniocerebral injury phenibut increases the number of mitochondria in the perifocal areas and improves the course of bioenergetic processes in the brain.
Phenibut also acts as an antioxidant.
When used in the elderly phenibut does not cause loadedness or excessive apathy.
The drug normalizes the processes of lipid peroxidation. Phenibut does not affect cholinergic and adrenergic receptors.
Phenibut has high absorption. The drug penetrates easily into all tissues of the body and crosses the blood-brain barrier (BBB). About 0.1% of the administered dose of the drug penetrates into the brain tissue (in young and old people to a much greater extent). Phenibut is evenly distributed in the liver and kidneys. The drug metabolizes in the liver up to 80–95%, the metabolites are not pharmacologically active. Phenibut does not cumulate. After 3 hours it begins to be secreted by kidneys, however, its concentration in the brain tissue does not decrease and it can be found in the brain for another 6 hours. About 5% of the drug is excreted unchanged by kidneys and partly with bile.

250 mg 3 times a day for 14 days.
250–500 mg once 1 hour before the expected onset of rolling or with the appearance of the first mild symptoms of seasickness. The effect of phenibut in such cases strengthens with the dosage increase. However, when severe seasickness signs (e.g. vomiting) have already arisen, the administration of phenibut is ineffective even in doses of 750–1000 mg.
Rare: Drowsiness, nausea, irritability, agitation, anxiety, dizziness, headache (in the beginning of the therapy), and allergic reactions.
Overdose can lead to increased side effects, like drowsiness, nausea, vomiting, arterial hypotension, renal insufficiency. If phenibut is used for a long time 7–14 g per day, a hepatotoxic effect (including fatty liver dystrophy) and eosinophilia may arise.
