Published July 24, 2025 · 6 min read · Updated April 2026

Reviewed for accuracy by licensed clinical professionals.

Gabapentin is increasingly used as an adjunct in alcohol and opioid withdrawal for its anti-anxiety, sleep-promoting, and mild pain-relieving properties.

In alcohol withdrawal

Reduces anxiety, insomnia, and cravings. Some protocols use gabapentin as the primary agent for mild alcohol withdrawal. More commonly used alongside benzodiazepines for moderate withdrawal.

In opioid withdrawal

Addresses anxiety, insomnia, and restless legs. Used as adjunct to buprenorphine or comfort medication protocols. Does not address core opioid withdrawal symptoms.

The abuse concern

Gabapentin itself has emerging abuse potential, particularly at high doses and in people with opioid use disorder. Several states have classified it as a controlled substance. Prescribers should monitor for misuse.
