How Long Does Phenibut Take to Work?

August 23, 2023

If you struggle with sleep disorders and anxiety, you’ve probably heard of Phenibut. What is Phenibut? This neuropsychotropic drug was developed in the Soviet Union in the 1960s as a tool to help Soviet astronauts remain focused and relaxed during their missions. It is widely used in Eastern Europe and can be legally purchased and used throughout most of Europe and in the United States.

Users typically report feeling relaxed after taking Phenibut. This includes feeling a reduction in stress levels, a boost in mood, and support with falling and staying asleep. It’s frequently used to treat anxiety disorders, depression, post-traumatic stress disorder (PTSD), alcoholism, and symptoms of alcohol withdrawal. It’s a powerful support drug–but how long does it take to activate so you can reap the benefits?

That depends on how you ingest the Phenibut. Most individuals opt to take a cosmic Phenibut capsule of 250 milligrams or by dissolving the powder into water, which takes approximately two hours to peak and to feel the effects. However, if ingested via sublingual consumption (a tab placed under the tongue and absorbed through that skin), individuals reported feeling the effects in as little as thirty minutes.

How Long Does Phenibut Stay In Your System?

No matter how you ingest Phenibut, you will likely feel the effects of it for between two to five hours. The duration of the effects entirely depends on relative factors, including:

• The user’s age
• The user’s body size
• The dosage amount
• And the user’s tolerance level

Still, just because you no longer feel the effects of Phenibut doesn’t mean it is completely metabolized and out of your system. Phenibut has what is called a ‘half-life’ for about five hours. A half-life is the amount of time it takes for 50% of a drug’s active substance to be metabolized in your body. What does this mean for Phenibut? It means the concentration of Phenibut in the body is cut to half the dosage around five hours after the initial intake.

It takes an additional five hours for the remaining half to metabolize. Phenibut is typically detectable in a person’s system for around twenty-six hours, depending on the dosage and the user’s metabolism. If you are taking larger doses (for example, 250 milligrams), anticipate that Phenibut may still be in your system for up to thirty-six hours after intake.

Is Phenibut Addictive?

All substances pose risk for abuse and addictions, be it physical or psychological dependence. Studies indicate Phenibut may be just as addictive as Valium or Xanax, so just like those drugs, use them appropriately by following instructions on the label or recommendations from your healthcare provider.

By misusing Phenibut by taking it too frequently or at too high of a dose, users may experience extremely risky (but rare) side effects of Phenibut. Improper use of Phenibut may increase chances of addiction and may lead to:

• Being unable to produce healthy levels of GABA (neurotransmitters that regulate anxiety/excitability) on own
• Seizures
• Hallucinations
• Psychosis
• Death

Phenibut Withdrawals

If a dependence and tolerance to Phenibut are formed, users who suddenly stop taking it may experience withdrawal symptoms within several hours or days. The most common withdrawal symptoms are ‘rebound effects,’ which are more severe recurrences of the symptoms the user was originally attempting to treat. Typically, these look like rebound effects relating to anxiety and insomnia.

Other symptoms include:

• Depression
• Agitation
• Tachycardia (elevated heart rate)
• Psychosis
• Fatigue
• Loss of appetite

Tapering Off of Phenibut

If you have concerns about your Phenibut usage and intake, it is recommended to ‘taper off’ the drug rather than quit ‘cold turkey,’ meaning, it’s better to take smaller and smaller doses than to suddenly stop altogether. 

If you or someone you love is struggling with Phenibut intake, seek help from a qualified clinician or healthcare professional. They may be able to offer support to lessen withdrawal symptoms and concurrent mental health issues that may have contributed to the addiction. They can develop a taper-off schedule and potentially use other non-addictive medications to help.
