Although there are many positive properties of this nootropic supplement, there is also potential for side effects when used improperly.
Generally speaking, it is safe when used at low dosages, but when the recommended dosage range is exceeded you may experience side effects similar to those that come with other GABA stimulators such as GHB or alcohol.
Because of this it is also recommended that you do not combine Phenibut with any other GABA agonists. Stacking Phenibut with any other GABAergics or agonists you are putting yourself at serious risk.
This also means that you should absolutely not be drinking any alcohol when taking your Phenibut dosage.
Various blogs and forums have users reporting that they have actually had to deal with withdrawal from Phenibut, suffering through normal withdrawal effects that come with it. For this reason it is important to keep your dosage at a low level, and to cycle your body off of it.

Phenibut may become addictive when used regularly for extended periods of time. This is mostly the case because as you use this supplement for a longer period of time your body begins to build up a tolerance to it so you need to increase your dose.
When increasing your dose and continuously taking this supplement for an extended period of time, you’re getting your body used to it and you will need more and more to achieve the same effects.
After a while when you want to stop using it, and maybe switch to something else, your body will have gotten accustomed to Phenibut constantly being in your system, and you will begin to show symptoms of withdrawal.
How to Dose Phenibut
Proper dosages of supplements depend on many factors including age, weight, personal sensitivities, and the reason for taking a supplement. Before taking any new supplement, it is recommended that you speak with your doctor.
Your doctor will be able to determine if the supplement is appropriate for your needs, if the supplement will negatively interact with any current supplements or medications you take, and what the best dosage is for your personally.
The following dosages are general guidelines only, and your personal dosage may differ. The average recommended dose for Phenibut ranges anywhere from 250 and 1000 milligrams.
Like with any other supplement, it’s best to start with a lower dose to give your body time to adjust to the foreign substance before increasing your intake to the normal level.
Phenibut also has a fairly long half-life compared to some other nootropic supplements, so you probably will not have to take more than one serving each day. However, if you think that the dosage you administered wasn’t large enough to show any effects, you must wait at least 4 hours before any follow-up intake of Phenibut.
When taking for the Phenibut for the second time in the same day, make sure that the day’s total does not exceed the maximum recommended dosage per 24 hour period.

In certain countries (Russia, Latvia and the Ukraine), Phenibut is prescribed under the brand names Noofen and Citrocard for the treatment of mood disorders and other medical conditions.

How to Prevent Side Effects
When paying attention to the recommended dosages, and using this supplement properly, there is a risk of experiencing Phenibut side effects.
Some of the most commonly reported mild side effects of Phenibut are fatigue, lightheadedness, headaches, nausea, and stomach discomfort. With high Phenibut doses, and in more serious cases of potential overdose, there is also a possibility of loss of consciousness and memory loss.
When taking Phenibut, simply mix the appropriate dosage with juice or water and drink the solution. Some users have reported the powder to taste a little sour, so sweeter juices are recommended to mask the taste. If even then the taste is unbearable to you, you may want to look into capsules.
Like any other supplement or drug you should know the risks that come with all of the benefits. It is very important to always follow the instructions on how to take Phenibut. Do not put your health at risk by trying to achieve better effects through high doses; remember that more is not always better.
Preventing Tolerance and Withdrawal
One well-documented problem with Phenibut is that the body quickly develops a tolerance to the effects of this drug, meaning that a higher dosage is needed to attain the same benefits.
Like the phenomenon of alcohol tolerance, users become less sensitive to the effects of phenibut with regular use. Phenibut works on the same receptors in the brain as alcohol.
As GABA receptors become stimulated by the presence of these agonist drugs, their expression is down-regulated such that the amount of GABAergic neurotransmission decreases with repeated dosages. Higher dosages are needed to activate the receptors and promote the same neurological effects.
Over a long period of time, this increases the risk of serious side effects and can make it harder to stop taking Phenibut without experiencing adverse withdrawal symptoms.
Some people appear to be more susceptible to developing a tolerance to this drug than others. The best way to prevent these side effects is to avoid using Phenibut on a daily basis and never take dosages more than the recommended amount.
Users report cycling on and off of this GABA agonist at low dosages or only taking it on certain days of the week. Some people may not experience withdrawal symptoms or psychological dependence even after taking it for several consecutive days, while others can begin to feel withdrawal when taking it two or three days in a row.
