Phenibut withdrawal appears to have a range of severity. It is important to recognize that patients undergoing phenibut abstinence may have progressive symptom worsening during early withdrawal. All published cases of abrupt phenibut abstinence were admitted inpatients for symptom management. Benzodiazepines or barbiturates with adjunctive baclofen appear to be the most commonly used drugs for moderate to severe withdrawal. Outpatient management via slow phenibut tapers with or without adjunctive gamma-aminobutyric acid agonist therapy may be successful. However, there is no standard treatment
