Can You Take Gabapentin with Suboxone?

Reviewed by Josie Desmarais, PMHNP-BC · Board-Certified Psychiatric-Mental Health Nurse Practitioner · Last updated June 2026

Taking gabapentin while on Suboxone is medically possible and sometimes clinically appropriate — but it requires active prescriber oversight, not patient self-management. Both are CNS depressants. Combined, they amplify sedation and significantly increase the risk of respiratory depression. In 2019, the FDA issued a specific Drug Safety Communication flagging this combination. Whether it is appropriate for you is a clinical decision based on your full picture — not a general yes or no.

Combining medications safely is exactly what supervised medication-assisted treatment is designed to manage.

Why This Combination Requires Caution: The FDA Warning

FDA Drug Safety Communication (2019): The FDA specifically warned about combining gabapentinoids — gabapentin and pregabalin (Lyrica) — with CNS depressants, including opioids and buprenorphine. The warning cited documented cases of serious respiratory depression and death, particularly in patients with underlying respiratory compromise or those combining these medications with additional depressants such as alcohol or benzodiazepines. For more on this, see our guide to whether Suboxone shows up on a drug test.

This is not a theoretical interaction. It is documented in adverse event reports and reflects a real pharmacological risk.

Suboxone (buprenorphine/naloxone) and gabapentin depress the CNS through different mechanisms, but both ultimately suppress central nervous system activity:

• Buprenorphine is a partial opioid agonist that acts on the brainstem respiratory centers — the same pathway through which opioid overdoses cause death.
• Gabapentin (and pregabalin) modulates voltage-gated calcium channels. On its own, its respiratory effect is modest. Combined with buprenorphine, the effect compounds in ways that exceed the sum of either drug alone.

When a Provider Might Prescribe Both

Many people enrolled in MAT carry co-occurring conditions that may legitimately warrant gabapentin. Clinical scenarios where a prescriber might intentionally use both:

Neuropathic pain: Gabapentin is a first-line treatment for peripheral neuropathy — common in people with a history of heavy alcohol use, diabetes, or chemotherapy. If buprenorphine alone does not address neuropathic pain, gabapentin may be clinically appropriate with monitored dosing.

Anxiety or sleep disorders: Gabapentin is used off-label for generalized anxiety and insomnia. Some patients find it helpful in early MAT when anxiety and sleep disruption are significant barriers to stabilization.

Alcohol use disorder: Gabapentin has evidence for reducing alcohol craving and withdrawal symptoms. In patients managing both OUD and alcohol use disorder, a prescriber may use both with close monitoring. We cover why Suboxone can make you tired in a separate article.

Seizure disorders: Gabapentin is an anticonvulsant. If a documented seizure disorder requires gabapentin, that continues regardless of MAT enrollment.

The critical distinction: all of these are deliberate clinical decisions made by a prescriber who knows both medications are in play — not a situation where a patient receives gabapentin from one provider without disclosing their Suboxone to the other.

The Real Risk: Fragmented Prescribing

The scenario that produces the worst outcomes: a person on Suboxone through one provider visits a pain clinic, urgent care, or primary care office — and receives gabapentin without the prescriber knowing about the buprenorphine. This fragmentation happens regularly in settings without complete medication reconciliation. If that applies to you, read more about how long Suboxone blocks opiates.

Your responsibility as a patient: disclose every medication you take to every prescriber you see. This includes:

• Suboxone or any buprenorphine formulation
• Any benzodiazepines
• Alcohol consumption patterns
• Any other gabapentinoid (pregabalin/Lyrica)

If you also take gabapentin and alcohol, or gabapentin, Suboxone, and a benzodiazepine — the additive CNS depression risk escalates substantially. Do not combine these without your full prescriber team knowing.

Red Flags That Require Emergency Care

If you are on both gabapentin and Suboxone and experience any of the following, call 911:

• Breathing that is slow, shallow, or stops
• Cannot be roused — extreme drowsiness that does not respond
• Blue or gray discoloration around lips or fingernails (cyanosis)
• Confusion or loss of consciousness

These are signs of respiratory depression. Do not wait to see if it resolves.

At less acute levels, contact your prescribing provider at your next visit — or sooner if worsening:

• Sedation that prevents normal daily functioning
• Difficulty staying awake during the day
• Balance problems or coordination issues
• New or worsening cognitive fog

Frequently Asked Questions

Is it safe to take gabapentin with Suboxone?
It carries real risk. The FDA has specifically warned about this combination. Both are CNS depressants, and together they increase sedation and respiratory depression risk. The combination should only occur under active medical supervision by a provider who knows both medications are being used.

Can gabapentin make Suboxone less effective?
Not directly. Gabapentin does not significantly alter buprenorphine’s receptor binding or metabolism. The concern is additive CNS depression — both drugs suppressing the nervous system simultaneously — not a pharmacokinetic interaction. Our team also explains how to maximize Suboxone absorption in detail.

I’m already taking both — what should I do?
Do not stop either medication abruptly. Both can cause withdrawal or complications if stopped suddenly. Contact your prescribing provider to review the combination. If you have concerns about how it is affecting you, that conversation needs to happen sooner rather than later.

My urgent care or dentist prescribed gabapentin — should I be concerned?
Yes — contact your MAT prescriber right away and let them know. They can review your current doses, assess your sedation risk, and advise whether any adjustment is needed. Learn more about who can prescribe Suboxone here.

How do I know if my doses are a dangerous combination?
There is no universal threshold. Risk depends on the doses of both medications, your individual metabolism, your respiratory health, and whether other depressants are involved. This is a clinical assessment your prescribing provider makes — not a number you can calculate yourself.
