Does Gabapentin Have a Withdrawal Syndrome?
Even those who take gabapentin as prescribed may develop some physical dependence; however, those who misuse it or abuse it recreationally may experience significant levels of dependence and withdrawal symptoms when they try to quit or slow its use. There are documented cases of withdrawal symptoms in people who took daily doses between 400mg to 8000mg for at least 3 weeks.
The gabapentin withdrawal syndrome may resemble some of the symptoms of alcohol and benzodiazepine withdrawal. This similarity may be due to the fact that gabapentin and these other substances all act on gamma-aminobutyric acid, or GABA, which is an inhibitory neurotransmitter in the brain.
The primary withdrawal symptoms associated with gabapentin use include:
In addition, people who are taking gabapentin for seizures and suddenly stop taking it may experience a rebound in or increased frequency of seizure activity, including continuous, uncontrollable seizures (status epilepticus).
Withdrawal usually occurs within 12 hours to 7 days after quitting the medication. Though a withdrawal timeline hasn’t been clearly documented, some studies have noted symptoms that last up to 10 days.

- Length of use.
- Medical or mental health problems.

People who wish to quit gabapentin should work with a physician to taper off the medication. Going “cold turkey” can lead to severe complications. One example of this stems from the fact that gabapentin is commonly prescribed for the treatment of seizures. If someone prone to seizures suddenly stops taking gabapentin, they may begin to have seizures that do not stop (status epilepticus). This condition is life-threatening and requires hospitalization.
Undergoing a gradual taper as part of a supervised medical detox can minimize the risk of these complications as well as facilitate the management of any medical problems that you may experience during withdrawal.
