What is Gabapentin?

A doctor may occasionally prescribe it off-label for certain mental health conditions such as anxiety or bipolar disorder. It is also occasionally used for insomnia, hot flashes, and restless leg syndrome.

It is available in tablets. It fits short-term applications, however, a doctor may use it long-term if benefits prevail the risks.

Is there an interaction between Gabapentin and alcohol?

Gabapentin is an anticonvulsant medication for partial seizures and nerve pain caused by shingles infections in adults and children. It works by decreasing sensitivity to pain when prescribed for postherpetic neuralgia, and by affecting low levels of calcium when prescribed to treat seizures. While relatively safe to take as directed by the doctor, some interactions with this medication may cause severe side effects. Taking Gabapentin and alcohol in combination should be avoided.

Alcohol is a sedative with a variety of effects. It has the potential for altering mental processes. The effects of alcohol resemble medications used to produce sleepiness for surgery, and it works very quickly. In small doses, Gabapentin and alcohol produce sedation, while their excessive consumption may lead to abuse and dependence. In some individuals, excessive consumption of alcohol may lead to several persisting side effects including:

  • Nausea
  • Headache
  • Agitation
  • Depression
  • Insomnia
  • Seizures

Taking Gabapentin and alcohol together may increase the risk of experiencing nervous system side effects, as well as impaired thinking and judgment. Among other potential dangers of combined Gabapentin and alcohol consumption are:


Mixing Gabapentin and alcohol may lead to extreme intoxication. An individual may lose concentration, experience dizziness, drowsiness, and nausea, among others. Incidents of choking on vomit may occur.


Taking Gabapentin and alcohol in high doses may lead to memory loss and poor alertness. An individual may faint or be unable to remember long-term memories.


Overdose incidents have been reported when mixing Gabapentin and alcohol. Both substances may slow breathing and lower heart rate. A combination of Gabapentin and alcohol in high doses may be deadly.

Mood changes. 

Gabapentin and alcohol in combination may lead to uncontrolled behaviors, where an individual exposes himself to dangerous activities.

Suicidal thinking.

Gabapentin and alcohol may increase the risk of suicidal thinking. The use of this medication alone is already linked to such risk, so taking Gabapentin and alcohol together can be extremely dangerous.


Gabapentin and alcohol in combination produce extreme sedation, decrease motor control, and increase risk of falling.

Doctors advise to abstain from combining Gabapentin and alcohol. When using both substances, they may alter or enhance the effects of each other. 

You should only take this medication as directed by the doctor. Gabapentin and alcohol should not be mixed.

What research supports Gabapentin for anxiety?

  • Gabapentin was studied for efficacy in generalized anxiety disorder (GAD) treatment. A 59-year-old female with GAD and major depressive disorder (MDD) was psychiatrically hospitalized where she was administered with Gabapentin 600-900 mg doses daily for 10 months. After a 10 month follow-up, she showed significant remission of anxiety symptoms with 900 mg doses.
  • Gabapentin was studied against a placebo for social anxiety disorder treatment. 69 subjects were divided into two groups, the first group took Gabapentin 3600 mg/daily, the second group took the placebo for 14 weeks. The results demonstrated that the medication reduced anxiety scores by 27 points with the Liebowitz Social Anxiety Scale (LSAS), compared to 12 points in the placebo group.
  • Gabapentin was studied for anxiety reduction before surgery. 40 subjects were randomly assigned to Gabapentin 1200 mg or placebo 1-2 hours before the surgery. The results demonstrated that the Gabapentin-group had lower anxiety scores than the placebo.
