Gabapentin is not an approved medication for the treatment of alcohol use disorder, but some doctors may prescribe it “off-label” to help with symptoms of alcohol withdrawal, such as tremors, seizures, and anxiety. It is believed to work by increasing the levels of a neurotransmitter called GABA, which can help to calm the overactive nervous system during withdrawal. However, it is important to note that the use of gabapentin for alcohol withdrawal should only be done under the close supervision of a medical professional, and it should not be used as a sole treatment for alcohol addiction.
