Gabapentin is a very common medication prescribed to treat a range of pain and seizure disorders, as well as restless leg syndrome. Even though it’s typically considered safe when it’s used as directed, long-term use can still lead to physical dependence. This means once your body has become dependent on it, stopping suddenly can cause withdrawal symptoms ranging from simply uncomfortable to medically significant, and even dangerous.
Patients and people close to them should know how gabapentin works and why withdrawal symptoms occur. Understanding what symptoms to expect, how the tapering process is approached, and the duration of withdrawal is crucial for informed decisions that affect your health. The tapering schedule is determined by your healthcare provider, with consideration for your symptoms.
What is Gabapentin & Why Does it Cause Withdrawal?
Gabapentin is a prescription medication that affects the way nerves send messages to the brain.[1] It is used to treat partial seizures and nerve pain, but is also prescribed off-label for things like insomnia and anxiety.
While it was originally designed to mimic the calming effects of the neurotransmitter gamma-aminobutyric acid (GABA), gabapentin doesn’t act directly on GABA receptors. Instead, it alters calcium channel activity in the brain, leading to reduced excitability and stabilization of neurons.[2]
With time and consistent use, the brain and body become physiologically dependent on gabapentin. This means that your nervous system has adapted to require a dose of gabapentin for normal function. When the medication is reduced or stopped too quickly, the system is altered, triggering the onset of withdrawal symptoms.
These symptoms can occur in those who aren’t misusing gabapentin but are the result of long-term use. This is one of the reasons why those who use it for long-term pain management or seizure prevention report symptoms, like anxiety, agitation, and sleep disturbances, when the medication dose is reduced or discontinued
Symptoms of Gabapentin Withdrawal
Specific symptoms of gabapentin withdrawal will vary depending on the dosage, the duration of use, and individual health factors. Here are some of the most common symptoms.
Common physical symptoms include:[3]
- Nausea and vomiting
- Headaches
- Dizziness or lightheadedness
- Sweating and chills
- Muscle pain or twitching
- Fatigue
Psychological symptoms that may appear:[4]
- Anxiety or panic
- Irritability
- Restlessness
- Mood swings
- Confusion or difficulty concentrating
How Long Does Gabapentin Withdrawal Last?
In most cases, the timeline for withdrawal will be fairly predictable. Most individuals will start to notice symptoms anywhere from 12 to 24 hours after their last dose of the medication.[5] The symptoms typically peak in intensity around day 3.
Around days 7 to 10, individuals should experience a substantial decrease in symptom intensity.[6] In some cases, minor withdrawal syndrome symptoms will linger a few more days before finally fading entirely.
There is a risk of seizures during the withdrawal stage.[7] That’s one of the primary reasons it’s essential to detox with medical supervision. Even if you’ve never misused the medication, stopping without a taper can create serious risks to your health.
Why Stopping Gabapentin Suddenly is Risky
Individuals who stop taking their prescription suddenly can experience a rebound of the symptoms that it was managing. Since gabapentin alters the way the nervous system operates, the brain adapts to its presence. If the medication is removed too quickly, the central nervous system may become overstimulated. This can lead to serious complications, including seizures
For people who have been taking gabapentin for chronic pain or anxiety, sudden withdrawal can cause sharp mood swings, distressing insomnia, and physical discomfort. These issues not only increase the risk of relapse but can also cause unnecessary suffering.
To reduce these risks, experts recommend a supervised tapering plan, which involves gradually decreasing the dose over time. Doing so gives the body time to adjust to functioning without the drug, minimizing symptoms and improving your chances of a smooth and stable recovery.
What to Expect From the Tapering Process
Even if you aren’t taking higher doses or participating in gabapentin misuse, a tapering plan is the safest and most effective way to stop taking gabapentin. Rather than quitting cold turkey, tapering allows your body and brain to gradually adjust to lower doses, reducing both the intensity and duration of withdrawal symptoms.
Tapering schedules vary depending on how long you’ve been taking gabapentin, what dose you’ve been prescribed, and any co-occurring medical conditions or mental health challenges. In most cases, a healthcare provider will reduce the dose in small steps. This is usually done over a period of several weeks.
Throughout the process, it’s important to monitor symptoms and communicate with your provider. If withdrawal symptoms become too uncomfortable or new concerns arise, the taper can be adjusted. Some individuals also benefit from the temporary use of supportive medications, such as sleep aids or anti-anxiety medications, during the taper.
It’s essential to remember that no two tapering plans are the same, and there’s no one-size-fits-all plan that will work for everyone. The primary focus should be on working with a qualified and trustworthy provider who understands your goals and is willing to adjust the plan as your needs evolve.
When to Seek Higher-Level Care
Some individuals need a higher level of care (such as inpatient care vs outpatient) or more intensive support during their taper (such as detox) to help with gabapentin withdrawal. This can be particularly helpful if the symptoms feel like they’re becoming unmanageable, or if there’s already a history of substance use disorder.[8]
Some indicators that you may need higher-level care include persistent insomnia, intense anxiety, depression, or suicidal thoughts. If you begin to experience confusion, tremors, or signs of seizures, it’s critical to seek immediate medical help.
Medical detox facilities and inpatient programs offer medical monitoring, medication management, and therapeutic support. These environments are especially helpful for individuals who are withdrawing from multiple substances. Higher-level care offers a structured and safe environment where physical and emotional needs can be addressed simultaneously.

Gabapentin withdrawal can be uncomfortable, but it doesn’t have to be dangerous. With a thoughtful tapering plan, medical oversight, and self-care strategies in place, it’s possible to manage symptoms and move forward with confidence. No one should feel like they have to face this process alone.
For those who have used gabapentin as part of a broader addiction history, detox may be just the beginning of recovery. Continued participation in addiction treatment programs, counseling, and community support groups can help you maintain wellness and avoid setbacks. Healing takes time, effort, and commitment, but with the right foundation, lasting recovery is an achievable goal.
