Updated 07/12/2023

Gabapentin is a prescription medication commonly used for nerve pain, seizures, alcohol use disorder, alcohol withdrawal and insomnia. It was once thought to be a safe, non-addictive drug that became widely used for chronic pain and neurological conditions. In 2017, 68 million prescriptions were written for gabapentin, making it the tenth most commonly prescribed medication in the U.S.

Gabapentin is not classified on the federal level as a controlled substance by the Food and Drug Administration, but some states have increased monitoring and reclassified gabapentin as a controlled substance at the state level. This is mainly due to the risk of misuse and of physical dependence, which leads to gabapentin withdrawal symptoms.

Does Gabapentin Cause Withdrawal?

Gabapentin withdrawal happens when you are physically dependent on the drug, in that your body struggles to function normally without it. When a dependent person stops using gabapentin, they may experience withdrawal symptoms.

When gabapentin is used alone or with other substances, especially when misused, there is a risk of dependence. Gabapentin dependence can occur any time from three weeks to five years after starting the medication. Higher doses increase the risk of dependence and withdrawal symptoms from stopping gabapentin. Gabapentin misuse involves taking higher than prescribed amounts of gabapentin or using gabapentin with other substances, like opioids.

Gabapentin Withdrawal Symptoms

Gabapentin withdrawal symptoms often occur after suddenly stopping the medication or rapidly decreasing the dose. The most common gabapentin withdrawal symptoms include:

  • Abnormal sweating
  • Agitation
  • Anxiety
  • Confusion
  • Disorientation
  • Headache
  • Insomnia

Several reports of other rare withdrawal symptoms include:

Gabapentin Withdrawal Seizures

Gabapentin should not be stopped without talking to a healthcare provider. Stopping gabapentin suddenly can increase the risk of gabapentin withdrawal seizures, especially in people with a history of seizures. Studies have shown that seizures can occur after abruptly stopping gabapentin, even in those who have never had a seizure before.

Gabapentin Withdrawal Timeline

Gabapentin withdrawal symptoms typically occur within  12 hours to seven days of stopping gabapentin. Most commonly, withdrawal symptoms start after one to two days.

Withdrawal symptoms occur quickly after stopping gabapentin due to its short half-life. A half-life is how long it takes your body to eliminate half the dose of a substance. The half-life of gabapentin is five to seven hours but may be longer in people with kidney disease. It usually takes about five half-lives for a drug to leave the body completely. This means it can take as many as 35 hours for your body to remove your last dose of gabapentin.

Rapid decreases in dose or abruptly stopping gabapentin results in withdrawal symptoms. Gradually tapering the gabapentin dose can reduce withdrawal symptoms. In some people, it has taken as long as 18 weeks of tapering the gabapentin dose to completely stop taking gabapentin while managing withdrawal symptoms.

What Helps Gabapentin Withdrawal?

Withdrawal symptoms from stopping gabapentin can be uncomfortable and sometimes life-threatening. Options for managing gabapentin withdrawal symptoms can include:

Restarting gabapentin

Magnesium supplements

Slowly tapering gabapentin dosage

Exercise and a healthy diet

There are no official guidelines for the management of gabapentin withdrawal. Strangely enough, gabapentin is often restarted when withdrawal symptoms are severe. Restarting gabapentin typically stops withdrawal symptoms within three days. The most effective management of withdrawal symptoms is gradually tapering the gabapentin dose.

Magnesium For Gabapentin Withdrawal

Taking magnesium supplements during gabapentin taper at least two hours after a gabapentin dose may help reduce gabapentin withdrawal symptoms. Studies have demonstrated the benefits of magnesium in reducing opiate withdrawal symptoms. Magnesium may reduce the severity of withdrawal symptoms through its effects on calcium channels and neuromediators such as dopamine, serotonin and glutamate.

Magnesium supplements should be taken at least two hours after taking gabapentin. Magnesium can decrease how much gabapentin your body absorbs. This may cause symptoms of gabapentin withdrawal. Separating magnesium supplements and gabapentin keeps magnesium from binding to the gabapentin and prevents your body from absorbing the full gabapentin dose.

Lorazepam For Gabapentin Withdrawal

Benzodiazepines, like lorazepam, are often used to manage symptoms of opioid and alcohol withdrawal. Since gabapentin withdrawal symptoms are similar to those seen in withdrawal from other substances, lorazepam was thought to be a potential treatment for gabapentin withdrawal symptoms. However, several case reports have shown benzodiazepines to be ineffective at reducing gabapentin withdrawal symptoms.


The best method of controlling gabapentin withdrawal symptoms is gradually tapering gabapentin doses. The tapering protocol used for opioids can be individualized to meet the needs of the person discontinuing gabapentin. Tapering protocols vary and can be adjusted based on the need for symptom control.


Physical activity and exercise may improve pain severity, physical function and quality of life. Even light to moderate exercise has a beneficial effect on dopamine levels in the brain. Increased dopamine levels activate the reward pathway affected by drug dependence and balance the decreasing dopamine levels that occur during withdrawal.

Developing a healthy exercise routine can not only aid in easing withdrawal symptoms and improving mood, but it can also help prevent cravings after withdrawal. It may be beneficial to consult a healthcare provider when deciding what types of exercises and the amount of physical activity is right for you. Exercise can be a valuable part of the detox process when appropriately added to your treatment plan.

Healthy Diet

A healthy diet may help ease certain withdrawal symptoms and supply your body with the nutrients and energy needed during recovery. A balanced diet can help improve your health and mood. It may be helpful to follow these tips for healthy eating:

Eat low-fat foods

Eat foods high in protein, complex carbohydrates and fiber

Avoid high-calorie, low-nutrient snacks, such as sweets

Stick to regular meal times

Add vitamin and mineral supplements to a well-balanced diet when recommended by a healthcare provider

How To Stop Taking Gabapentin

Do not suddenly stop taking gabapentin or rapidly decrease your gabapentin dose. With the help of a healthcare provider, you should slowly taper your gabapentin dose over several weeks. There is no set guideline for tapering gabapentin, but it is recommended to start decreasing by an average of 25% reduction in dose with each reduction.

Gabapentin dosing tapers should be done slowly over weeks to months as tolerated. You should be closely monitored during a gabapentin taper. Dosage adjustments can be made for the elderly, individuals with kidney disease, adverse events and the appearance of withdrawal symptoms.

Only taper gabapentin as instructed by your healthcare provider. Below is an example of a possible gabapentin taper that may be advised.

Medically Supervised Gabapentin Detox

The body eliminates gabapentin from the system during detox. Some people may be able to go through detox at home by closely following a gabapentin tapering schedule prescribed by their healthcare provider. For others, it may be dangerous to go through withdrawal from gabapentin at home.

People with a history of life-threatening gabapentin withdrawal symptoms such as seizures or other pre-existing conditions should go through gabapentin detox in an environment where they can be closely monitored. Medically supervised gabapentin detox provides 24-hour supervision by caring medical professionals to keep you safe and comfortable during detox.

Often gabapentin detox is necessary for individuals addicted to more than one substance, called polysubstance abuse. About 15% to 20% of people with opioid use disorder also reported gabapentin misuse. The risk of gabapentin abuse is higher in people with opioid use disorder. Medically supervised detox, like the detox program at The Recovery Village at Palmer Lake, provides support for individuals needing to detox from multiple substances.
