Phenibut is a synthetic GABA derivative that’s become a hidden threat at gas stations, smoke shops, and online retailers across America. Marketed as a “nootropic,” “brain booster,” or “supplement,” this unregulated substance produces effects similar to alcohol or benzodiazepines—and can cause severe addiction with dangerous withdrawal symptoms including seizures and psychosis.
At Nova Transformations in Matthews, NC, we’ve seen increasing numbers of patients struggling with phenibut dependence. Our PHP and IOP programs provide the medical supervision needed for safe recovery from this dangerous substance.
⚠️ Dangerous Withdrawal
Phenibut withdrawal can cause life-threatening seizures and psychosis. Do NOT attempt to quit cold turkey. Medical supervision is strongly recommended for anyone with regular phenibut use.
What Is Phenibut?
Phenibut (beta-phenyl-gamma-aminobutyric acid) was developed in the Soviet Union in the 1960s as an anti-anxiety medication. It’s still prescribed in Russia and some Eastern European countries under names like Anvifen, Fenibut, and Noofen.
In the United States, phenibut is not FDA-approved for any medical use and does not meet the legal definition of a dietary supplement. Despite this, it’s widely sold online and at retail locations as a “nootropic” or “supplement” with claims to reduce anxiety, improve sleep, and enhance cognition.
How Phenibut Works
Phenibut acts primarily on GABA-B receptors in the brain—the same receptors affected by alcohol and drugs like baclofen and GHB. It produces:
- Anti-anxiety effects
- Euphoria and mood enhancement
- Sedation and relaxation
- Muscle relaxation
- Reduced social inhibition
Why It’s So Addictive
Phenibut produces rapid tolerance—users need increasing doses to achieve the same effects, often within days of regular use. Physical dependence can develop in as little as 1-2 weeks, and withdrawal symptoms closely resemble alcohol or benzodiazepine withdrawal.
