Does gabapentin help you sleep?

Gabapentin is a prescription medication that may help you sleep. That may be why it has been prescribed for people with insomnia, even though it is not approved for that use.

Gabapentin is available on prescription. It comes as tablets, capsules and a liquid that you swallow.

Key facts

  • You’ll usually take gabapentin 3 times a day. You can take it with or without food.
  • Most people who take gabapentin do not get any side effects. But some people may feel sleepy, tired and dizzy. Common side effects are usually mild and go away by themselves.
  • It takes at least a few weeks for gabapentin to work.
  • Most people do not have to stay on the same brand of gabapentin as there’s very little difference between brands.
  • Some people can become addicted to gabapentin after taking it for a long time. When stopping gabapentin you’ll need to reduce your dose gradually to avoid withdrawal symptoms.
  • If you have epilepsy, you are entitled to free prescriptions for all the medicines you take, not just your epilepsy ones. You can get an application form from your doctor’s surgery.

However, gabapentin enacarbil (Horizant) has been approved by the Food and Drug Administration (FDA) to treat a sleep disorder called restless legs syndrome (RLS).

  • One of the most common side effects of gabapentin is drowsiness.
  • In people taking gabapentin for its approved conditions (certain epileptic seizures and postherpetic neuralgia), 19% of patients older than 12 years of age with epilepsy and 21% of patients with postherpetic neuralgia reported drowsiness as a side effect.

Gabapentin and sleep

Most studies show that gabapentin improves slow wave sleep (“deep sleep”) and total sleep time.

  • Two small studies showed that gabapentin may help people with primary insomnia and occasional sleep disturbance improve total sleep time and wakefulness in the morning.
  • In other studies, it appears that gabapentin may improve sleep in people with other medical conditions that make it more difficult to sleep, such as alcohol dependence, hot flashes and bipolar disorder.

In a large review of 26 studies on gabapentin and sleep in patients with other medical conditions, the average dose taken daily was about 1,800 mg. Although positive sleep outcomes were reported, the researchers noted that gabapentin was not tolerated as well as placebo and some patients stopped taking it. Misuse and abuse of the drug has also been reported.

It takes about 2 to 3 hours for immediate-release gabapentin to reach its fullest effect, and it’s typically taken 3 times per day.

RLS treatment

Gabapentin may also be used to treat RLS, a disorder that makes it hard to fall asleep or stay asleep. RLS causes an uncontrollable and uncomfortable urge to move your legs, which is worse at night.

The FDA has approved gabapentin enacarbil (Horizant) — a long-acting gabapentin — as a treatment for RLS.

Side effects of gabapentin

The most common side effects with gabapentin include:

  • Clumsiness
  • Viral infection
  • Drowsiness
  • Nausea and vomiting
  • Speaking difficulties
  • Tremor
  • Swelling, usually involving the legs and feet
  • Fatigue
  • Fever
  • Movements that are jerky
  • Coordination difficulties
  • Double vision
  • Unusual eye movement
  • Serious reactions can include:
  • Difficulty breathing
  • Allergic reactions with swelling of the throat or face

Is gabapentin a narcotic/controlled substance?

The anti-seizure medication gabapentin is not currently considered a narcotic or controlled substance by the federal government, but certain states have enacted legislation so that the medication is treated as one or monitored by the state’s prescription drug monitoring program.

The use of a controlled substance is regulated by the federal government to prevent abuse or misuse. Prescription drug monitoring programs track prescriptions of certain medications to flag individuals who may be misusing them and at risk of an overdose.

In addition to preventing seizures in individuals with epilepsy, gabapentin may be prescribed to treat nerve or neuropathic pain caused by herpes virus or shingles in adults.

Gabapentin may be considered as an alternative to opioids, which can be highly addictive and result in overdoses and death. Often prescribed to treat pain, opioids are a controlled substance. Gabapentin is known as an opioid potentiate because it can increase the high felt with opioids such as fentanyl, oxycodone, hydrocodone, codeine, morphine and even the street drug heroin.

As a result, gabapentin has potential for misuse or abuse. The combination of opioids and gabapentin may increase the risk of dying from an overdose likely due to depressed breathing. Individuals with chronic obstructive pulmonary disease (COPD) and the elderly are at greatest risk of dying from this combination.

What happens when you suddenly stop taking gabapentin?

Case reports have shown that gabapentin withdrawal can last for up to 5 days or longer, but the duration has not been well established in human studies. The symptoms and how long they last depend on how much of the drug you are taking and for how long you’ve been taking it.

Gabapentin withdrawal is not a common problem unless you are abusing the drug.

Abuse means taking gabapentin in higher than prescribed amounts and taking it for reasons not intended by your doctor.

A study on gabapentin abuse from 1993 through 2015 showed that people who experienced withdrawal were taking an average of 3,000 mg (600 to 8,000 mg) of gabapentin per day, but some case reports mention withdrawal symptoms at 400 mg per day.

What happens when you suddenly stop taking gabapentin?

If you are taking gabapentin at a normal dose prescribed by your doctor and you don’t have a history of substance abuse, you are less likely to have withdrawal symptoms when you stop taking it.

Higher doses and a history of substance problems pose more risk for abuse. You can start to build up a tolerance to the drug, and you may need to take even more of it to get the desired effect. This is called physical dependence.

Your brain cells (neurons) become dependent on a high dose of the drug for normal functioning. When the drug is stopped, your brain becomes temporarily disorganized. If you start to feel that you need more of the drug to function, stopping suddenly is more likely to lead to withdrawal symptoms.

Withdrawal symptoms may start within 12 hours or take up to 7 days to begin after stopping suddenly. Symptoms commonly include:

      • Restlessness (agitation)
      • Disorientation
      • Confusion

Various case reports describe these other symptoms of gabapentin withdrawal:

  • Headache
  • Body/stomach pain
  • Anxiety
  • Heart palpitations
  • Sweating
  • Muscle twitching
  • Light sensitivity
  • Restless limb movements
  • Nervousness

What is the treatment for gabapentin withdrawal?

There are no approved medications to treat gabapentin withdrawal. The only reliable treatment is to slowly taper the drug under the supervision of your doctor, usually a substance abuse specialist. Sometimes gabapentin is restarted to ease withdrawal symptoms before tapering off.

There is no evidence to show that other drugs or supplements — such as magnesium or CBD oil — are helpful in treating withdrawal symptoms.

Most case reports show that withdrawal patients went back onto gabapentin to relieve their symptoms. But there may be unreported cases of gabapentin withdrawal, as not everyone seeks treatment.

How can I avoid gabapentin withdrawal?

The best way to avoid gabapentin withdrawal is to only take the drug in the dose prescribed by your doctor for its approved uses.

Gabapentin is a prescription medication approved to treat certain types of seizures and nerve pain that follows a herpes infection (postherpetic neuralgia). A long-acting form is used to treat restless legs syndrome. The most common brand name is Neurontin.

Gabapentin is also prescribed and used for unapproved reasons. These are called off-label uses. Off-label uses for gabapentin include:

  • Substance abuse treatment
  • Migraine headaches
  • Fibromyalgia
  • Mental health disorders
  • Insomnia

People with a history of drug or alcohol abuse may be at increased risk for:

  • Tolerance
  • Self-dose escalation
  • Drug-seeking behavior
  • Withdrawal symptoms

Does gabapentin cause weight gain?

Gabapentin may cause weight gain, but it is a rare side effect. Gabapentin is used to treat epilepsy.

It’s also taken for nerve pain, which can be caused by different conditions, including diabetes and shingles. Nerve pain can also happen after an injury.

In epilepsy, it’s thought that gabapentin stops seizures by reducing the abnormal electrical activity in the brain.

With nerve pain, it’s thought to block pain by affecting the pain messages travelling through the brain and down the spine.

Gabapentin is available on prescription. It comes as tablets, capsules and a liquid that you swallow.

Studies have shown that a small number of people taking gabapentin, a drug used to treat epilepsy and postherpetic neuralgia, experienced weight gain. People who do gain weight may gain about 5 pounds after 6 weeks of use.

    • In people with epilepsy, weight gain occurred in 3% of people older than 12 years of age who were taking gabapentin (compared to 2% of people taking the placebo). Weight gain was also seen at a similar rate in pediatric epilepsy patients who were 3 to 12 years old.
    • In people with postherpetic neuralgia, 2% of patients taking gabapentin experienced weight gain. No weight gain was found among people taking the placebo.

The cause of weight gain with gabapentin is likely due to increased appetite. You may be hungry more often. In some cases, weight gain may be due to fluid retention, another side effect of gabapentin. Another possible cause is not getting enough exercise if gabapentin is causing fatigue.

Some ways to avoid weight gain include:

    • Eating a healthy and balanced diet
    • Eating smaller portion sizes
    • Avoiding high-calorie snacks and desserts like chips, pastries and sweets
    • Eating low-calorie snacks like fruits and vegetables to manage hunger
    • Getting regular exercise

Swelling from fluid retention may be reduced by:

    • Sitting with your feet raised
    • Avoiding standing for long periods of time

If gabapentin is causing you to gain weight, do not stop taking this drug on your own. Stopping the drug suddenly can lead to serious problems, especially if you are taking gabapentin for seizures. Abruptly stopping a seizure medicine can cause seizures that won’t stop.

Weight gain is one of many possible side effects. The most common side effects with gabapentin include:

    • Clumsiness
    • Viral infection
    • Sleepiness
    • Nausea and vomiting
    • Speaking difficulties
    • Tremor
    • Swelling, usually involving the legs and feet
    • Fatigue
    • Fever
    • Movements that are jerky
    • Coordination difficulties
    • Double vision
    • Unusual eye movement

How long does it take gabapentin to work?

It can take several weeks for gabapentin to reach its full effect, but this depends on the condition being treated.

Gabapentin is approved to treat:

      • Nerve pain
      • Some types of seizures
      • Restless legs syndrome (RLS)

It also depends on your individual response to the drug. The time gabapentin takes to work is not the same for everyone.

The effective dose of gabapentin is also very different for each person. It may vary from 300 mg per day to up to 3,000 mg per day.

Another reason gabapentin takes time to work is that the dose is usually started low and gradually increased over time to reach an effective dose.

For example, when used to relieve nerve pain, the initial dose may be started at 300 mg and increased by 300 mg daily over several days, gradually reaching up to 600 mg three times per day. Studies for nerve pain treatment show that pain relief may begin within 1 week, with the maximum effect reached after about 4 weeks.

Gabapentin is in a class of medications called anticonvulsants. It is not completely known how this drug works. When used to treat a type of seizure disorder, called a partial onset seizure, gabapentin decreases the abnormal activity in the brain that causes the seizures. When used to treat nerve pain, or neuralgia, following a herpes zoster (shingles) infection, gabapentin may reduce the response to painful stimuli. It is unknown how gabapentin relieves symptoms of restless legs syndrome.

Even though it may take up to 4 weeks to get the full effects of gabapentin, it is important not to stop taking it suddenly. That could cause withdrawal symptoms such as:

      • Anxiety
      • Insomnia
      • Nausea
      • Pain

If you are taking gabapentin to control seizures, stopping suddenly may increase your risk of a seizure.

Common side effects of Gabapentin

These common side effects of gabapentin may happen in more than 1 in 100 people. They’re usually mild and go away by themselves.

There are things you can do to help cope with them:

    • Feeling sleepy, tired or dizzy
    • Feeling sick (nausea)
    • Being sick (vomiting)
    • Diarrhoea
    • Mood changes
    • Swollen arms and legs
    • Blurred vision
    • Dry mouth
    • Difficulty getting an erection
    • Weight gain
    • Memory problems
    • Headaches
    • Getting more infections than usual

Keep taking the medicine, but talk to your doctor if this advice does not help and the side effects bother you or do not go away.

 

Is gabapentin considered a painkiller?

Gabapentin is commonly used to treat some types of nerve pain but is classified as an anticonvulsant medicine, not as an opioid or painkiller.

Gabapentin was first approved in 1993 and is used to treat:

    • postherpetic neuralgia, a nerve pain caused by the shingles virus (herpes zoster),
    • restless legs syndrome (RLS), a painful movement disorder in the legs
    • partial seizures in adults and children at least 3 years old who have epilepsy

Gabapentin works by affecting chemicals and nerves in the body that are involved in the cause of seizures and in some types of nerve pain.

Gabapentin is not a federally-controlled drug substance and does not contain an opioid (narcotic) medication. However, gabapentin misuse and abuse has been reported, and it may be restricted in some states through their state drug-monitoring program. Gabapentin abuse can boost the high a person gets from opioid painkillers, muscle relaxants, and anxiety medications. This can be dangerous and potentially life-threatening.

In 2019, the FDA issued an alert that serious breathing problems have been reported with gabapentin and other related drugs, like Lyrica (pregabalin) in people at risk of slowed breathing.

    • This includes people who use opioid pain medicine or CNS depressants, people with chronic obstructive pulmonary disease (COPD, and the elderly.
    • These serious breathing problems may be fatal.
    • Read more about this serious FDA warning here.

Avoid or limit the use of alcohol (in beverages or medicines) with gabapentin as it can worsen drowsiness or dizziness. Ask you doctor about drinking alcohol while you are taking gabapentin.

What type of pain does gabapentin treat?

Gabapentin is approved by the FDA to treat:

Postherpetic neuralgia: nerve pain that can occur due to an outbreak of shingles. Shingles, also known as herpes zoster, occurs when the chicken pox virus deep-seated in your nerve activates again later in life and causes a serious skin rash. Not everyone gets postherpetic neuralgia from shingles, but it can be painful if you do. It causes a burning nerve pain that lasts for months, or even years, after the rash and blisters have cleared up.

Restless legs syndrome (RLS): an uncontrollable urge to move your legs around, often at night. This is usually due to leg discomfort. It may occur most often when you are sitting, laying down, or during bedtime. It can be disruptful to sleep and travel. It is thought RLS may occur due to an imbalance of the chemical dopamine in the brain.

Gabapentin has also been used off-label for the treatment of other types of neuropathic (nerve) pain like peripheral diabetic neuropathy, fibromyalgia and trigeminal neuralgia. “Off-label” uses of gabapentin are uses that have not been approved by the FDA and are not found in the package insert, but may have been accepted for use by healthcare providers based on clinical use.

How does gabapentin come?

There are several brand names of gabapentin including Gralise, Horizant, and Neurontin. Use only the brand and form of gabapentin your doctor has prescribed.

Gralise (gabapentin) is indicated for the management of postherpetic neuralgia only. It is not used for epilepsy. Gralise comes as a 300 and 600 milligram (mg) extended-release (ER) tablet and in a 30-day starter pack of 78 tablets. A generic option is not yet available.

Horizant (gabapentin enacarbil) is used in adults to treat either nerve pain due to postherpetic neuralgia (PHN) or restless legs syndrome (RLS). Horizont is also an extended-release 300 mg or 600 mg tablet and is not interchangeable with other gabapentin products. A generic option is not yet available.

Neurontin (gabapentin) is an immediate-release form used to treat seizures in adults and children who are at least 3 years old, in addition to nerve pain due to shingles. It comes as 100, 300, or 400 mg oral capsules; 600 mg and 800 mg oral tablets, and as a 250 mg per 5 mL oral solution. It is also available as a generic option.

Some brands are only used for certain conditions, and these products may not be interchangeable. Check your medicine each time you get a refill to make sure you have received the correct form.

Some of these medicines may be expensive. Ask your healthcare provider if you are able to use a generic form of gabapentin for your condition (this may not always be possible). Generic options could save you hundreds of dollars each month, or may be less expensive than your insurance copay.

Also, check with the manufacturer who may offer copay cards or patient assistance programs to lessen your overall costs, if you qualify. Be sure to check for online coupons, too, that can save you money on both generics and brands.

Does gabapentin help nerve pain?

Gabapentin is approved to treat the type of nerve pain (neuralgia) that results from nerve damage. Gabapentin is used to treat neuralgia caused by a herpes zoster viral infection, also known as shingles.

This pain is called post-herpetic neuralgia (PHN), and it can be severe and chronic. Gabapentin is also used to treat pain from diabetic neuropathy, which happens when nerves in the feet damaged by diabetes cause chronic burning pain.

The exact way that gabapentin works to relieve pain is not known. It may change the way the body senses and reacts to pain. Gabapentin is used to manage long-term (chronic) pain, not to be taken for pain as needed. Chronic pain can interfere with sleep and work, and lead to depression.

Studies show that pain relief may start within one week and reach a maximum effect in about 4 weeks. It can take this long because gabapentin is usually started at a low dose and gradually increased over time until it works.

For treating neuralgia, gabapentin is often started at 300 mg per day and gradually raised by 300 mg per day. One 2017 review of 37 studies found that pain relief usually occurs at a dose of 1,200 mg or more.

The same review compared gabapentin to an inactive medicine (placebo) in almost 6,000 adults with chronic pain from PHN or diabetic neuropathy. Study participants were given either gabapentin or a placebo for 4 to at least 12 weeks. The results showed that 30-40% of people taking gabapentin were able to reduce their pain by half or more, compared to 10-20% of people taking the placebo.

Although some people may get significant relief, others may have side effects without relief of pain. More than half of people taking gabapentin did not get significant relief and had side effects from the drug.

According to the review, about 60% of people taking gabapentin had side effects, including:

      • Dizziness
      • Sleepiness
      • Water retention (edema)
      • Clumsiness while walking (ataxia)

It does not typically make pain worse: In trials comparing gabapentin side effects to placebo side effects, only 1% of people reported increased pain, and this was the same for gabapentin and placebo.

Once you find the dose that relieves neuralgia for you, it is important not to stop taking it suddenly. Stopping suddenly can lead to withdrawal symptoms such as:

      • Anxiety
      • Insomnia
      • Nausea
      • Pain
      • Sweating

Why Is Lyrica a Controlled Substance?

Lyrica is a controlled substance that falls under schedule V classification. Some patients develop a dependence, requiring help to stop using it.

Lyrica is a controlled substance that belongs to a class of medications rated as having the lowest potential for abuse. Lyrica isn’t a narcotic, but it does produce similar effects.

People with a history of alcohol or drug abuse are at a greater risk of abusing Lyrica. Additionally, researchers have received reports of physical and/or psychological dependence.

Every year, thousands of people abuse prescription medications at least once, according to statistics from the National Institute on Drug Abuse. Understanding how your medications work and taking them according to your doctor’s instructions are two critical steps in minimizing the risk of abusing Lyrica.

Why Is Lyrica a Controlled Substance?

Lyrica is a Schedule V drug, which places it among those with the lowest potential for abuse. For this reason, research on the prevalence of Lyrica addiction has been minimal.

Studies do show that Lyrica produces psychoactive effects, such as euphoria, that are similar to those produced by other controlled substances. Reports have surfaced of patients abusing the medication. Research also suggests that although Lyrica is considered a controlled substance, it could serve as a viable substitute for medications that put patients at higher risk of abuse and addiction, including benzodiazepines and opioids.

What Is in Lyrica That Makes It a Controlled Substance?

So, what’s in Lyrica that makes it a controlled substance? This prescription medication, known as pregabalin in its generic form, isn’t a narcotic.

It’s a gamma-amino-butyric acid (GABA) analog that’s roughly three to four times more potent than its predecessor, gabapentin, according to research published by the U.S. National Library of Medicine. It works by powerfully binding to components of the nervous system to soothe damaged or overactive nerves.

Side effects like dizziness and sleepiness could increase if you take Lyrica with alcohol or narcotic medications.

Although more research on Lyrica withdrawal is needed to fully understand the risks, patients who stop taking it without tapering the dosage over time could experience various withdrawal symptoms.
