Gabapentin Addiction: Signs, Symptoms, And Treatment

Medically Reviewed by Johnelle Smith, M.D. on

Gabapentin is a nerve pain medication that can lead to potentially life-threatening side effects and withdrawal symptoms. If you or someone you know may be abusing gabapentin, here are the signs and symptoms, side effects, and treatment options to keep in mind.

Gabapentin Abuse, Addiction, And Treatment

Gabapentin, a gabapentinoid, is an anticonvulsant drug made by Pfizer that the U.S. Food & Drug Administration (FDA) approved to augment other drugs treating epilepsy.

This medication also treats postherpetic neuralgia as a result of shingles and restless leg syndrome.

Off-label, medical providers use gabapentin (formerly under brand names Gralise and Neurontin) in psychiatry to treat mental health issues such as depression, anxiety, and bipolar.

It has even been used with methadone to relieve opiate withdrawal.

Prescribing physicians may also recommend the use of gabapentin for fibromyalgia, neuropathy, nerve pain (neuropathic pain), and chronic pain as an alternative to opioids.

Gabapentin is increasingly becoming a drug of abuse both in the United States and Great Britain.

Is Gabapentin Addictive?

Gabapentin is not listed as a controlled substance, but it has been documented to have abuse potential. It is not known to be highly addictive.

It is similar to benzodiazepines in that it interacts with gamma-aminobutyric acid (GABA) in the brain.

The state of Kentucky has listed gabapentin as a controlled substance even though it is not on the federal schedules of drugs.

However, high doses of the drug alone also create a euphoric effect and the misuse of gabapentin is thought to be one of the reasons why gabapentin prescriptions are on the rise.

Signs of gabapentin abuse can include:

  • drowsiness
  • tremors
  • mood swings
  • anxiety
  • memory problems

How Do People Misuse Gabapentin?

There are many different ways people abuse gabapentin. The most common method is simply by taking more of the pills than are prescribed by medical providers.

But there are other methods of abuse.

Snorting Gabapentin

Snorting gabapentin involves crushing the medication into a powder and using a straw or similar device to snort it up your nose.

Nasal passages allow gabapentin to enter your system more quickly than swallowing it. However, snorting drugs can cause damage to the nasal tissues and other parts of the nose.

Plugging Gabapentin

Sometimes, people who abuse gabapentin plug the medication. Plugging is a method of dissolving a medication in water and injecting it into the anus.

People may believe that injecting the drug that way gives them a faster and more intense high.

What Are The Side Effects Of Gabapentin Misuse?

Just like any other substance use disorder, there are side effects of gabapentin addiction.

Because gabapentin is a central nervous system (CNS) depressant, misuse can cause confusion, difficulty recalling recent events, and sleepiness.

How Long Gabapentin Stays In The Body

Gabapentin has a half-life of about seven to eight hours.

Unlike many drugs and substances, gabapentin is metabolized through the kidneys, so it clears the body pretty quickly. Within 48 hours, most traces of gabapentin will be gone.

The following drug tests may detect the presence of gabapentin:

Mixing Gabapentin With Other Substances Leads To A Range Of Risks

Gabapentin is commonly abused with other drugs, because people may believe that it makes the highs more intense. However, mixing gabapentin with other drugs comes with considerable risks.

Alcohol And Gabapentin

Gabapentin and alcohol are dangerous to mix because both substances are central nervous system depressants.

Taking them together can dangerously affect both your brain and your respiratory system.

Cocaine And Gabapentin

People who use cocaine will sometimes use it with gabapentin to counteract some of the harsher effects of the stimulant.

But both drugs have similar overdose symptoms like vomiting and depressed respiration.

Other Gabapentin Drug Interactions

Gabapentin is also commonly taken with opioids or heroin. Once again, the big concern is the effects on the respiratory system, since both drugs can depress it.

What Other Dangers Occur With Gabapentin Abuse?

Gabapentin abuse can lead to severe drowsiness which can cause poor performance at work.

Additionally, gabapentin abuse can lead to these dangers:

  • memory loss
  • confusion
  • suicidal thoughts and actions
  • respiratory failure

Finally, abusing gabapentin can also lead to physical dependence.

Does Gabapentin Addiction Cause Withdrawal?

Gabapentin addiction can cause withdrawal symptoms if you suddenly stop taking it. These symptoms may begin around seven hours after last use and continue for up to five days.

Gabapentin withdrawal symptoms can include:

  • confusion
  • anxiety
  • body pain
  • muscle twitching

Can Gabapentin Cause A Drug Overdose?

Yes, gabapentin can cause an overdose with many potentially dangerous symptoms. It is most likely to lead to drug overdose when mixing gabapentin with other drugs or alcohol.

Symptoms of a gabapentin overdose can include:

  • drowsiness
  • sedation
  • double vision
  • slurred speech
  • diarrhea

If you know anyone who takes gabapentin and is experiencing these symptoms, you should seek medical help right away.

Does Gabapentin Abuse Require Detox?

To date, there is no medical detox for gabapentin and no indication that supplements like magnesium help with the symptoms of withdrawal.

The best way to detox from gabapentin is to slowly taper off use of the drug with the help of a detox program.

What Are The Treatment Options For Gabapentin Abuse?

Addiction treatment for gabapentin can include several different parts. Depending on whether you are abusing other drugs, you may need to have inpatient care for a time.

  • support groups

Another important aspect of addiction treatment includes aftercare to help you manage triggers and cravings for the drug.
