Can You Abuse Gabapentin? Understanding the Risks

The Short Answer: Yes, Gabapentin Can Be Abused

While gabapentin (brand names Neurontin, Gralise, Horizant) was once considered to have minimal abuse potential, growing evidence shows that this prescription medication can indeed be misused and abused. Originally approved by the FDA to treat seizures and nerve pain, gabapentin has become one of the most commonly prescribed medications in the United States—and with that widespread use has come increasing reports of abuse, dependence, and addiction.

Research published in the journal Addiction found that gabapentin misuse has increased significantly over the past decade, particularly among individuals with a history of substance use disorders. The medication is now recognized as having abuse potential, especially when taken in high doses or combined with other substances like opioids.

What Is Gabapentin and Why Is It Prescribed?

Gabapentin is an anticonvulsant medication that affects chemicals and nerves in the body involved in seizures and pain signals. It's FDA-approved to treat:

• Partial seizures in adults and children
• Postherpetic neuralgia (nerve pain following shingles)
• Restless leg syndrome (in the extended-release form Horizant)

However, gabapentin is frequently prescribed "off-label" for conditions including anxiety disorders, bipolar disorder, migraines, fibromyalgia, and chronic pain. This widespread prescribing has made gabapentin one of the top 10 most prescribed medications in the United States, with over 64 million prescriptions written annually.

How Is Gabapentin Abused?

People abuse gabapentin in several ways to achieve euphoric or intoxicating effects:

Taking Higher Than Prescribed Doses

The most common form of gabapentin abuse involves taking significantly more than the prescribed amount. While therapeutic doses typically range from 900-3,600 mg per day, individuals abusing the medication may take 3,000-5,000 mg or more at once. A study in Drug and Alcohol Dependence found that people misusing gabapentin often take doses 2-3 times higher than prescribed.

Combining with Other Substances

Research shows that gabapentin is frequently abused in combination with opioids, benzodiazepines, or alcohol to enhance their effects. According to a comprehensive review published in the Pharmacotherapy Journal, this combination significantly increases the risk of respiratory depression and overdose death. The combination of gabapentin with opioids has been shown to increase opioid-related deaths by 49%.

Alternative Routes of Administration

Some individuals crush and snort gabapentin capsules or dissolve them for injection, though these methods are less common due to the medication's poor bioavailability through these routes.

Why Do People Abuse Gabapentin?

Understanding the motivations behind gabapentin abuse helps explain why this medication has become a substance of concern:

Euphoric Effects

At high doses, gabapentin can produce feelings of euphoria, relaxation, and calmness similar to marijuana or alcohol intoxication. Users describe a "high" characterized by:

• Feelings of calm and relaxation
• Mild euphoria
• Increased sociability
• Dissociation from reality
• Sedation and drowsiness

Opioid Enhancement

A significant finding from research published in Pharmacotherapy shows that gabapentin is commonly used to enhance the effects of opioids. The medication can intensify the euphoric effects of opioids while also helping to manage withdrawal symptoms, making it particularly attractive to individuals with opioid use disorder.

Easy Accessibility

Unlike controlled substances, gabapentin is not classified as a Schedule II-V drug at the federal level (though some states have begun regulating it). This makes it easier to obtain through prescriptions, and it's often perceived as "safer" than traditional drugs of abuse.

Self-Medication

Many people misuse gabapentin to self-medicate for anxiety, insomnia, or withdrawal symptoms from other substances. The medication's calming effects make it appealing for managing these conditions, even without medical supervision.

The Science Behind Gabapentin Abuse

A groundbreaking study published in Addiction Biology examined the neurological mechanisms that make gabapentin susceptible to abuse. The research found that gabapentin affects the brain's reward system by:

• Increasing dopamine release in the nucleus accumbens, a key brain region involved in pleasure and reward
• Modulating GABA neurotransmission, which produces calming and anxiolytic effects
• Affecting calcium channels in ways that can produce euphoria at high doses

According to research from the National Center for Biotechnology Information (NCBI), gabapentin's abuse potential is particularly pronounced in individuals with a history of substance use disorders. A comprehensive review published in Pharmacotherapy found that up to 40-65% of individuals in substance abuse treatment programs reported misusing gabapentin.

Warning Signs of Gabapentin Abuse

Recognizing the signs of gabapentin abuse is crucial for early intervention. Common indicators include:

Behavioral Signs

• Taking more medication than prescribed
• Running out of prescriptions early
• "Doctor shopping" to obtain multiple prescriptions
• Obtaining gabapentin from friends or family members
• Combining gabapentin with alcohol or other drugs
• Continuing use despite negative consequences
• Preoccupation with obtaining and using the medication

Physical Signs

• Drowsiness and sedation
• Dizziness and loss of coordination
• Slurred speech
• Memory problems
• Tremors or involuntary eye movements
• Respiratory depression (especially when combined with opioids)

Psychological Signs

• Mood swings
• Anxiety when unable to access the medication
• Depression
• Cognitive impairment
• Hostility or aggression

Risks and Dangers of Gabapentin Abuse

Overdose Risk

While gabapentin overdose alone is rarely fatal, it becomes extremely dangerous when combined with other central nervous system depressants. Research from the Journal of Clinical Pharmacology indicates that gabapentin-involved overdose deaths have increased by 4,000% between 2010 and 2019, primarily due to polysubstance use.

Symptoms of gabapentin overdose include:

• Severe drowsiness
• Double vision
• Slurred speech
• Diarrhea
• Respiratory depression
• Loss of consciousness
• Coma (in severe cases)

Physical Dependence and Withdrawal

Contrary to earlier beliefs, research now confirms that gabapentin can cause physical dependence. A study published in Pharmacotherapy documented withdrawal symptoms in patients who abruptly stopped taking gabapentin after prolonged use.

Gabapentin withdrawal symptoms may include:

• Anxiety and agitation
• Insomnia
• Nausea and sweating
• Pain and discomfort
• Confusion and disorientation
• Seizures (in severe cases)
• Rapid heart rate

Cognitive Impairment

Long-term gabapentin abuse can lead to significant cognitive problems, including memory loss, difficulty concentrating, and impaired decision-making abilities. These effects may persist even after stopping the medication.

Increased Mortality Risk

According to research published in PLOS Medicine, individuals prescribed gabapentin alongside opioids have a 49% increased risk of opioid-related death compared to those taking opioids alone. This finding has led to increased scrutiny of gabapentin prescribing practices, particularly in patients with substance use disorders.

Gabapentin Abuse in Special Populations

Individuals in Recovery

People in recovery from opioid or alcohol use disorders are at particularly high risk for gabapentin abuse. The medication may be prescribed to manage anxiety or pain, but its mood-altering effects can trigger relapse or lead to a new addiction. Studies show that 15-22% of individuals in opioid treatment programs misuse gabapentin.

Prison Populations

Research indicates that gabapentin abuse is prevalent in correctional facilities, where it's sometimes referred to as "prison heroin" or "johnnies." The medication is often diverted and traded among inmates for its intoxicating effects.

Chronic Pain Patients

Individuals prescribed gabapentin for chronic pain may develop tolerance, requiring higher doses to achieve pain relief. This can inadvertently lead to abuse and dependence, particularly if underlying substance use disorders are present.

State Responses to Gabapentin Abuse

In response to growing evidence of abuse, several states have begun regulating gabapentin more strictly:

• Kentucky (2017) - First state to classify gabapentin as a Schedule V controlled substance
• Michigan (2019) - Added gabapentin to Schedule V
• Tennessee (2019) - Classified as Schedule V
• Virginia (2019) - Added to Schedule V
• West Virginia (2018) - Classified as Schedule V
• Ohio (2022) - Added to prescription monitoring program

These regulatory changes require prescribers to check prescription drug monitoring programs before prescribing gabapentin and limit the number of refills allowed.

Treatment for Gabapentin Abuse and Addiction

If you or someone you know is struggling with gabapentin abuse, professional treatment is essential. Attempting to quit gabapentin "cold turkey" can be dangerous, particularly for individuals taking high doses or using the medication long-term.

Medical Detoxification

The first step in treatment is often medical detoxification, where healthcare professionals supervise the gradual tapering of gabapentin to minimize withdrawal symptoms. This process typically involves:

• Gradual dose reduction over several weeks or months
• 24/7 medical monitoring
• Medications to manage withdrawal symptoms
• Nutritional support and hydration
• Psychological support

Comprehensive Treatment Programs

Following detox, comprehensive treatment addresses the underlying causes of addiction and provides tools for long-term recovery. Treatment options include:

Inpatient/Residential Treatment

Provides 24/7 care in a structured environment, typically lasting 30-90 days. This level of care is recommended for individuals with:

• Severe gabapentin dependence
• Co-occurring substance use disorders
• Mental health conditions
• Previous unsuccessful treatment attempts
• Unstable living situations

Outpatient Treatment

Allows individuals to live at home while attending therapy sessions several times per week. Suitable for those with:

• Mild to moderate dependence
• Strong support systems
• Work or family obligations
• Stable living environments

Medication-Assisted Treatment (MAT)

For individuals with co-occurring opioid use disorder, MAT may be appropriate. Medications like buprenorphine or methadone can help manage cravings and withdrawal while addressing gabapentin misuse.

Therapeutic Approaches

Evidence-based therapies used in gabapentin addiction treatment include:

• Cognitive Behavioral Therapy (CBT) - Identifies and changes thought patterns that lead to substance abuse
• Motivational Interviewing - Enhances motivation to change and commit to treatment
• Contingency Management - Provides positive reinforcement for maintaining sobriety
• Group Therapy - Offers peer support and shared experiences
• Family Therapy - Addresses family dynamics and builds support systems
• Dual Diagnosis Treatment - Addresses co-occurring mental health conditions

Prevention and Safe Use of Gabapentin

For individuals prescribed gabapentin legitimately, following these guidelines can help prevent abuse:

• Take exactly as prescribed - Never increase doses without consulting your doctor
• Store securely - Keep medication in a locked cabinet away from others
• Avoid alcohol - Never combine gabapentin with alcohol or other sedatives
• Communicate openly - Discuss any history of substance abuse with your prescriber
• Monitor for warning signs - Be aware of tolerance development or cravings
• Dispose properly - Use drug take-back programs for unused medication
• Regular check-ins - Maintain regular appointments with your healthcare provider

The Bottom Line

Yes, gabapentin can absolutely be abused, and the evidence shows that abuse of this medication is increasing. While gabapentin serves important medical purposes when used appropriately, its potential for misuse—particularly among individuals with substance use disorders—cannot be ignored.

If you're struggling with gabapentin abuse or know someone who is, it's crucial to seek professional help. Gabapentin dependence is a medical condition that requires proper treatment, not a moral failing. With appropriate care, recovery is possible.
