Once considered low-risk, gabapentin has turned up in roughly 1 in 10 opioid overdose deaths in some studies — a stark sign that gabapentin abuse is a growing, often-overlooked problem. This common prescription, taken by millions for nerve pain and seizures, is increasingly misused, especially in combination with opioids. That combination is the central danger: gabapentin can amplify opioids' effects and is now found in a significant share of opioid overdose deaths. Like its cousin pregabalin (Lyrica), gabapentin can cause dependence and a withdrawal that — in some cases — includes seizures, which is why it should never be stopped abruptly.
This guide explains what gabapentin is, why it's misused, the dangerous combinations, the withdrawal, and how abuse is treated. Updated April 2026. Reviewed by the RehabPulse editorial team. This is educational and not medical advice — never change your gabapentin dose without your prescriber.
The 60-second answer
| Question | Short answer |
|---|---|
| What is gabapentin? | A medication for nerve pain and seizures (brand: Neurontin) |
| Is it addictive? | Lower risk than opioids, but misuse and dependence are real |
| Why is it misused? | For mild euphoria and to boost the effects of opioids |
| The biggest danger? | Combined with opioids — raises overdose risk |
| Is there withdrawal? | Yes — including possible seizures if stopped abruptly |
| Should I quit cold turkey? | No — taper under medical supervision |
| Is it controlled? | Federally non-scheduled, but several states monitor/schedule it |
| How is it treated? | Medical taper plus addiction treatment as needed |
The single most important point: most people don't know that gabapentin's biggest danger isn't gabapentin alone — it's the combination with opioids, which can increase the risk of fatal overdose. Because gabapentin was marketed and prescribed as relatively benign, both patients and prescribers often underestimate it, and it's frequently used alongside opioids to enhance the high. Recognizing that this combination is dangerous, and that gabapentin needs to be tapered rather than stopped suddenly, is what prevents the worst outcomes.
What gabapentin is and why it's misused
Gabapentin (brand name Neurontin, among others) is a medication originally developed for epilepsy and now widely prescribed for nerve pain (neuropathy), restless legs, and various off-label uses. It calms overactive nerve signaling, which makes it genuinely useful — and it's one of the most prescribed medications in the US.
For most people taking it as directed, gabapentin is helpful and relatively low-risk. But it has misuse potential that's become clearer over time:
- Mild euphoria at high doses. At doses well above therapeutic, gabapentin can produce a calming, mild euphoric effect, which some people seek.
- Potentiating opioids. A major reason for misuse is that gabapentin can enhance the effects of opioids — making the opioid high stronger — which is also what makes the combination so dangerous.
- Easing withdrawal. Some people use it to self-manage withdrawal from opioids or other substances.
- Perceived as "safe" and accessible. Because it's a common, non-scheduled (federally) prescription, it's often easier to obtain than controlled substances, and its low-risk reputation lowers caution.
This pattern closely parallels its chemical cousin pregabalin — see our Lyrica pregabalin withdrawal guide, as both are "gabapentinoids" with similar misuse and dependence profiles. The anxiety many users are trying to manage connects to our anxiety and addiction guide.
Picture this: someone prescribed gabapentin for nerve pain hears that taking extra alongside their opioid painkillers makes everything feel better. It's "just gabapentin," they reason — a harmless nerve medication. But that combination is exactly the one driving gabapentin's appearance in overdose deaths, because both drugs depress the central nervous system and gabapentin amplifies the opioid. The "harmless" reputation is precisely what makes the dangerous combination feel safe — and that misperception is the heart of the problem.
The dangerous combinations
Gabapentin's risks rise dramatically when it's combined with other central nervous system depressants:
| Combination | Why it's dangerous |
|---|---|
| Gabapentin + opioids | Amplifies sedation and respiratory depression; raises overdose death risk |
| Gabapentin + benzodiazepines | Stacked sedation, dangerous respiratory depression |
| Gabapentin + alcohol | Increased sedation and impairment |
| High-dose gabapentin alone | Sedation, dizziness, impairment; misuse potential |
The standout danger:
- The opioid combination is the deadliest. Research has found gabapentin involved in a substantial portion of opioid-related overdose deaths, because it deepens the respiratory depression that kills in opioid overdose. This is the single most important risk to understand. Our how long does opioid withdrawal last guide and medication-assisted treatment guide cover the opioid side.
- Naloxone caveat. Because gabapentin isn't an opioid, naloxone won't reverse its contribution to an overdose — but you should still give naloxone for the opioid component and call 911.
- Polysubstance risk generally. Stacking gabapentin with any sedative (benzodiazepines, alcohol) compounds the danger.
This is why prescribers increasingly exercise caution co-prescribing gabapentin with opioids, and why several states have moved to schedule or monitor it through prescription drug monitoring programs.
Signs of abuse and withdrawal
The signs of gabapentin misuse resemble other substance misuse patterns:
- Taking more than prescribed or higher doses for an effect.
- Using it to get high or to boost other substances.
- Doctor-shopping or seeking early refills.
- Tolerance — needing more for the same effect.
- Withdrawal when stopping.
- Continued use despite problems, or using without a prescription.
Gabapentin withdrawal is real and can be significant, especially after high-dose or long-term use:
| Symptom | Notes |
|---|---|
| Anxiety and agitation | Often prominent |
| Insomnia | Disrupted sleep |
| Sweating, nausea | Autonomic and GI symptoms |
| Tremor, restlessness | Common |
| Pain rebound | Return of nerve pain it was treating |
| Seizures | A serious risk, especially with abrupt cessation |
The seizure risk is the critical safety point: like benzodiazepines (see our benzodiazepine withdrawal timeline guide) and pregabalin, abruptly stopping gabapentin after regular use can trigger seizures, which is why tapering under medical supervision matters.
How gabapentin abuse is treated
Gabapentin misuse is treatable, and the approach combines safe withdrawal with addressing the broader picture:
- Medically supervised taper. Because of the withdrawal and seizure risk, gabapentin should be tapered gradually under a doctor's guidance rather than stopped abruptly. The schedule is individualized — never adjust it yourself.
- Symptom management. Clinicians can help with the anxiety, insomnia, and other symptoms during the taper, making it more comfortable.
- Addressing co-use. Because gabapentin is so often misused with opioids, treating any opioid use disorder is central — medications for opioid use disorder (buprenorphine, methadone) and comprehensive care, as in our medication-assisted treatment guide.
- Behavioral therapy. CBT and other approaches address triggers, cravings, and the reasons behind misuse, including untreated pain or anxiety.
- Treating the underlying problem. If gabapentin was treating nerve pain or anxiety, alternative management is needed so stopping doesn't simply unleash the original condition.
- Harm reduction. For anyone using gabapentin with opioids, carrying naloxone and not using alone are sensible precautions given the overdose risk.
Imagine someone who's been quietly taking far more gabapentin than prescribed, alongside their opioids, not thinking of it as a "real" drug problem. When they work with a clinician who treats it seriously — a careful taper, treatment for the opioid use, therapy for the underlying pain and anxiety — they not only come off gabapentin safely but also reduce the overdose risk that the combination posed. Recognizing gabapentin misuse as worth treating, rather than dismissing it as "just a nerve pill," is what makes that safer outcome possible.

Frequently asked questions
Is gabapentin addictive? Gabapentin has lower addiction potential than opioids or benzodiazepines, but misuse and physical dependence are real and increasingly recognized. At high doses it can produce mild euphoria, and people misuse it for that effect, to enhance opioids, or to manage withdrawal. Regular use can lead to tolerance and dependence, so stopping produces a withdrawal syndrome. Its reputation as low-risk has led both patients and prescribers to underestimate it, but it warrants respect and careful use.
Why is gabapentin dangerous with opioids? Because both drugs depress the central nervous system, and gabapentin can amplify opioids' effects, the combination deepens sedation and respiratory depression — the mechanism that causes fatal opioid overdose. Research has found gabapentin involved in a substantial portion of opioid-related overdose deaths. This opioid combination is gabapentin's single most important danger, and it's why prescribers increasingly exercise caution co-prescribing the two. Naloxone won't reverse gabapentin's contribution, though it should still be given for the opioid component.
What are the symptoms of gabapentin withdrawal? Gabapentin withdrawal can include prominent anxiety and agitation, insomnia, sweating, nausea, tremor, restlessness, and a rebound of the nerve pain it was treating, typically beginning within a day or two of stopping. The most serious risk is seizures, especially with abrupt discontinuation after high-dose or long-term use. Because of this, gabapentin should be tapered gradually under medical supervision rather than stopped cold turkey.
Can you stop gabapentin cold turkey? You should not, especially after regular, high-dose, or long-term use. Abruptly stopping gabapentin can trigger withdrawal symptoms including, in some cases, seizures, and can cause a sharp rebound of the pain or anxiety it was treating. Like benzodiazepines and pregabalin, gabapentin should be tapered gradually under a doctor's guidance, on an individualized schedule, to allow the nervous system to readjust safely.
How is gabapentin abuse treated? Treatment combines a medically supervised gradual taper (to manage withdrawal and seizure risk) with addressing the broader picture: managing symptoms during the taper, treating any co-occurring opioid use disorder (often with medications like buprenorphine, since gabapentin is frequently misused with opioids), behavioral therapy like CBT, and proper management of the underlying pain or anxiety. Harm-reduction steps like carrying naloxone matter for anyone combining gabapentin with opioids. Gabapentin misuse is very treatable.
