Is it safe to drink alcohol while taking gabapentin, and what risks should I be aware of?

Quick answer

It’s generally best to avoid alcohol while taking gabapentin. Alcohol and gabapentin can both slow down the brain and nervous system, so using them together may increase drowsiness, dizziness, impaired thinking and motor skills, and can raise the risk of unsafe activities like driving. ^{[1] [2]} The official medication guidance advises not to drink alcohol with gabapentin unless you’ve first discussed it with your healthcare provider. ^{[1] [3]}

Why alcohol and gabapentin don’t mix

• Additive sedation and dizziness: Gabapentin can cause sleepiness and slow thinking; alcohol can intensify these effects, making you more groggy and unsteady. ^{[1] [2]}
• Impaired coordination and reaction time: Both can reduce motor skills and judgment, which increases the risk of falls, injuries, and accidents. ^{[1] [2]}
• Driving safety concerns: Guidance notes significant driving impairment may occur with gabapentin, and self‑assessment of alertness can be unreliable; alcohol makes this worse. ^{[4] [5]}

Specific risks you should consider

• Day‑to‑day functioning: You may feel more tired and lightheaded, and your thinking may feel slower, which can affect work, school, or caregiving responsibilities. ^{[1] [2]}
• Accidents and falls: The combination can increase the chance of falls, especially in older adults or anyone with balance issues. ^{[1] [2]}
• Operating machinery and driving: You should avoid driving or using heavy machinery until you know exactly how gabapentin affects you, and avoid alcohol because it can make impairment worse. ^{[1] [2]}
• Combined CNS depressant effects: When alcohol is used with other sedating medicines (like benzodiazepines, sleep aids, certain pain medicines), the overall depressant effect can become dangerous, with risks like profound sedation and breathing problems. While this general warning is strongest for opioids and benzodiazepines, alcohol contributes to the same direction of risk. ^{[6] [7]}

Practical guidance

• Avoid alcohol, especially at the start: When you’re beginning gabapentin or changing doses, it’s safest to skip alcohol until you know how you react. ^{[1] [2]}
• If your clinician allows limited alcohol: Consider small amounts only, never drive, and space alcohol well away from peak sedation (for example, not within several hours of your dose). This should be individualized with your provider. ^{[1] [3]}
• Check other medications: If you also take medicines that cause sleepiness (e.g., benzodiazepines, opioids, some antihistamines, sleep aids), alcohol adds to the sedative load; this combination should be avoided. ^{[6] [7]}
• Know when to seek help: If you feel unusually drowsy, confused, very dizzy, or have trouble breathing after drinking alcohol on gabapentin, get medical help. ^{[1] [2]}

Safety and overdose context

Gabapentin by itself has a relatively wide safety margin in overdose, but serious outcomes including rare death have been reported with very large ingestions; alcohol can complicate assessment and increase overall risk when mixed with sedating agents. ^{[8] [9]}

Key takeaways

• Do not drink alcohol while taking gabapentin unless you’ve first discussed it with your healthcare provider. ^{[1] [3]}
• Expect increased sleepiness, dizziness, and slowed thinking if alcohol is combined with gabapentin. ^{[1] [2]}
• Do not drive or do dangerous activities until you’re sure how gabapentin affects you, and avoid alcohol because it can worsen impairment. ^{[1] [4]}
