What is the Action Mechanism of Gabapentin ? Is Gabapentin Addictive ?

signs someone is addicted to gabapentin

The chemical structure of gabapentin (Neurontin) is derived by addition of a cyclohexyl group to the backbone of gamma-aminobutyric acid (GABA). Gabapentin prevents seizures in a wide variety of models in animals, including generalized tonic-clonic and partial seizures.

The exact mechanism of action with the GABA receptors is unknown; however, researchers know that gabapentin freely passes the blood-brain barrier and acts on neurotransmitters.

Gabapentin has a cyclohexyl group to the structure of neurotransmitter GABA as a chemical structure. Even though it has a similar structure to GABA, it does not bind to GABA receptors and does not influence the synthesis or uptake of GABA.

Gabapentin works by showing a high affinity for binding sites throughout the brain correspondent to the presence of the voltage-gated calcium channels, especially alpha-2-delta-1, which seems to inhibit the release of excitatory neurotransmitters in the presynaptic area which participate in epileptogenesis.

Even though there is no evidence for direct action at the serotonin, dopamine, benzodiazepine, or histamine receptors, research has shown gabapentin to increase total-blood levels of serotonin in healthy control subjects.

The elimination half-life of gabapentin is 5 to 7 hours, and it takes two days for the body to eliminate gabapentin from its system.

One benefit of gabapentin use is its mild side-effect profile. The most common side effects are fatigue, dizziness, and headache.

Gabapentin has no activity at GABAA or GABAB receptors of GABA uptake carriers of brain. Gabapentin interacts with a high-affinity binding site in brain membranes, which has recently been identified as an auxiliary subunit of voltage-sensitive Ca2+ channels. However, the functional correlate of gabapentin binding is unclear and remains under study.

Gabapentin crosses several lipid membrane barriers via system L amino acid transporters. In vitro, gabapentin modulates the action of the GABA synthetic enzyme, glutamic acid decarboxylase (GAD) and the glutamate synthesizing enzyme, branched-chain amino acid transaminase.

Results with human and rat brain NMR spectroscopy indicate that gabapentin increases GABA synthesis. Gabapentin increases non-synaptic GABA responses from neuronal tissues in vitro. In vitro, gabapentin reduces the release of several mono-amine neurotransmitters.

Gabapentin prevents pain responses in several animal models of hyperalgesia and prevents neuronal death in vitro and in vivo with models of the neurodegenerative disease amyotrophic lateral sclerosis (ALS). Gabapentin is also active in models that detect anxiolytic activity.

Although gabapentin may have several different pharmacological actions, it appears that modulation of GABA synthesis and glutamate synthesis may be important.

Is Gabapentin Addictive ?

Asking about the signs someone is addicted to gabapentin first begs the question: What is gabapentin?

To answer that question requires putting gabapentin in perspective as a pharmaceutical drug that, while providing relief to thousands of people for nerve pain, also has the potential for abuse. It isn’t an opioid, but it has found a niche audience among those who take it recreationally, and for doctors who began to seek alternatives to narcotics as the opioid epidemic reached its apex, it seemed like a safer alternative.

In 2016, gabapentin was the 10th most prescribed drug in the United States, with 64 million prescriptions written that year . That was up from 39 million prescriptions written only four years earlier, in large part because “gabapentin, an anticonvulsant and analgesic for postherpetic neuralgia, has been thought to have no abuse potential despite numerous published reports to the contrary,” according to a 2018 article in the journal Psychology of Addictive Behaviors.

In that particular article, researchers analyzed data from a study of drug users in Kentucky who reported using gabapentin for non-medical purposes. Their findings? “Overall, the sample reported having initiated gabapentin more than 10 years earlier after having it prescribed for a legitimate, though generally off-label, medical indication (e.g., pain, anxiety, opioid detoxification). Participants reported use of gabapentin in combination with buprenorphine, other opioids, cocaine, and caffeine to produce sought-after central nervous system effects (e.g., muscle relaxation, pain reduction, sleep induction, feeling drunk, and feeling ‘high’).”

Gabapentin, such studies reveal, can be problematic. Whether used in conjunction with other drugs or on its own, it can be abused, which makes it a substance of concern. To understand the signs someone is addicted to gabapentin, however, requires some knowledge of what it is, where it comes from, how it works and how it can be addictive.

Comparative Studies

Gabapentin and lamotrigine have been compared in an open, parallel-group, add-on, randomized study in 109 patients with uncontrolled partial epilepsy and learning disabilities. The two drugs were similarly efficacious, with similar incidences of adverse events and serious adverse events. Neither lamotrigine nor gabapentin exacerbated any of the challenging behaviors observed in these patients.

The most common adverse reaction to gabapentin was somnolence, which was mostly reported during the initial titration phase.

In a double-blind comparison of gabapentin and lamotrigine in 309 patients with new-onset partial or generalized seizures, the target doses were gabapentin 1800 mg/day and lamotrigine 150 mg/day.

Severe adverse events were reported in 11% of patients taking gabapentin and 9.3% of patients taking lamotrigine. Two patients had serious adverse events thought to be related to the study drug; one took an overdose of gabapentin and the other had convulsions with lamotrigine. The most frequent treatment-related adverse events in both treatment groups were dizziness, weakness, and headache; 11% of patients taking gabapentin and 15% of those taking lamotrigine withdrew because of adverse events. There was an increase of over 7% in body weight from baseline in 14% of the patients taking gabapentin and 6.6% of those taking lamotrigine. There were benign rashes in 4.4% of those taking gabapentin and 11% of those taking lamotrigine.

The hypothesis that both amitriptyline and gabapentin are more effective in relieving neuropathic pain than diphenhydramine has been tested in a randomized, double-blind, triple crossover, 8-week trial in 38 adults with spinal cord injuries [18]. Maximum daily doses were 2600 mg for gabapentin and 150 mg for amitriptyline.

Amitriptyline was more efficacious in relieving neuropathic pain than diphenhydramine. Withdrawal because of possible adverse reactions occurred five times during gabapentin treatment:

(1) shortness of breath;

(2) dizziness, fatigue, and nausea;

(3) increased spasticity and pain;

(4) fatigue, drowsiness, constipation, and dry mouth; and

(5) severe itching.

The four most frequent adverse events were dry mouth, drowsiness, fatigue, and constipation, which were all more common with amitriptyline.

 

Gabapentin is Used to Treat Seizures and Postherpetic Neuralgia ?

What is gabapentin?

Gabapentin is a prescription drug. It comes as an oral capsule, an immediate-release oral tablet, an extended-release oral tablet, and an oral solution.

Gabapentin oral capsule is available as the brand-name drug Neurontin. It’s also available as a generic drug. Generic drugs usually cost less than the brand-name version. In some cases, the brand-name drug and the generic version may be available in different forms and strengths.

Why it’s used

Currently, gabapentin has FDA approval for:

    • Postherpetic neuralgia
    • Adjunctive therapy in the treatment of partial seizures with or without secondary generalization in patients over the age of 12 years old with epilepsy, and the pediatric population, 3 to 12 year-olds with a partial seizure
    • Moderate to severe restless leg syndrome (RLS) moderate to severe

It also has off-label use for neuropathic pain, fibromyalgia, bipolar disorder, postmenopausal hot flashes, essential tremors, anxiety, resistant depressant and mood disorders, irritable bowel syndrome (IBS), alcohol withdrawal, postoperative analgesia, nausea and vomiting, migraine prophylaxis, headache, interstitial cystitis, painful diabetic neuropathy, social phobia, generalized tonic-clonic seizures, pruritus (itching), insomnia, post-traumatic stress disorder (PTSD), and refractory chronic cough.

Gabapentin oral capsule is used to treat the following conditions:

    • Seizures: Gabapentin is used to treat partial (focal) seizures. It’s taken together with other seizure medications in adults and in children 3 years of age and older who have epilepsy.
    • Postherpetic neuralgia: This is pain from nerve damage caused by shingles, a painful rash that affects adults. Shingles appears after infection with the varicella zoster virus. This virus occurs in people who have had chicken pox.

Nerve pain can be a symptom of many different conditions, including cancer, HIV, diabetes, and shingles. For some, nerve pain is frustrating; for others, nerve pain is devastating and life-changing.

Whether it feels like burning, pinpricks, or sudden shocks of electricity, nerve pain can disrupt your life at home and at work. It can limit your ability to get around. Over time, it can grind you down. Studies show that people with nerve pain have higher rates of sleep problems,anxiety, and depression.Your nervous system is involved in everything your body does, from regulating your breathing to controlling your muscles and sensing heat and cold.

There are three types of nerves in the body:

    1. Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation.
    2. Motor nerves. These nerves control your movements and actions by passing information from your brain and spinal cord to your muscles.
    3. Sensory nerves. These nerves relay information from your skin and muscles back to your spinal cord and brain. The information is then processed to let you feel pain and other sensations.

Because nerves are essential to all you do, nerve pain and damage can seriously affect your quality of life.

When you have a serious medical condition such as cancer or HIV, dealing with the additional misery of nerve pain can be especially hard. But there is good news. While nerve pain can’t always be cured, it can be treated — and there are a lot of good options available.

Experts believe that 40 million Americans are living with nerve pain. The impact of nerve pain is tremendous. Both the costs to the healthcare system as well as loss of wages and productivity are staggering.

What is Postherpetic Neuralgia ?

Postherpetic neuralgia (post-hur-PET-ik noo-RAL-juh) is the most common complication of shingles. The condition affects nerve fibers and skin, causing burning pain that lasts long after the rash and blisters of shingles disappear.

The chickenpox (herpes zoster) virus causes shingles. The risk of postherpetic neuralgia increases with age, primarily affecting people older than 60. There’s no cure, but treatments can ease symptoms. For most people, postherpetic neuralgia improves over time.

How Are Nerve Pain and Nerve Damage Treated?

In many instances, nerve damage cannot be cured entirely. But there are various treatments that can reduce your symptoms. Because nerve damage is often progressive, it is important to consult with a doctor when you first notice symptoms. That way you can reduce the likelihood of permanent damage.

Often, the first goal of treatment is to address the underlying condition that’s causing your nerve pain or nerve damage. This may mean:

    • Regulating blood sugar levels for people with diabetes
    • Correcting nutritional deficiencies
    • Changing medications when drugs are causing nerve damage
    • Physical therapy or surgery to address compression or trauma to nerves
    • Medications to treat autoimmune conditions

Additionally, your doctor may prescribe medications aimed at minimizing the nerve pain you are feeling. These may include:

    • Pain relievers
    • Tricyclic antidepressants
    • Certain anti-seizure drugs – Gabapentin

Complementary and alternative approaches may also help alleviate your nerve pain and discomfort. These include:

    • Acupuncture
    • Biofeedback
    • Hypnosis
    • Meditation

Dosage for postherpetic neuralgia

Adult dosage (ages 18–64 years)

    • Typical starting dosage: Day 1, 300 mg; day 2, 600 mg (300 mg two times per day, spaced evenly throughout the day); day 3, 900 mg (300 mg, three times per day, spaced evenly throughout the day). Your doctor may further increase your dosage after day 3.
    • Maximum dosage: 1,800 mg per day (600 mg, three times per day, spaced evenly throughout the day)

Child dosage (ages 0–17 years)

Dosage for people younger than 18 years has not been established.

Senior dosage (ages 65 years and older)

Your kidney function may decrease with age. Your body may get rid of this drug more slowly. Your doctor may start you on a lower dose so that too much of this drug does not build up in your body. Too much of the drug in your body can be dangerous. Your doctor may change your dose based on how well your kidneys are working.

Gabapentin in Non-Epilepsy Neuropathic Pain like Postherpetic Neuralgia

The FDA approved gabapentin for the management of postherpetic neuralgia in adults. Recently, gabapentin underwent systemic evaluation in the management of diabetic neuropathy. In 1998, Rowbotham and his research team concluded that in 229 postherpetic neuralgia patients, gabapentin had more significant pain reduction as early as two weeks after initiating the treatment.

Furthermore, other measurements of mood, depression, anger-hostility, fatigue, and physical functioning, were more effectively managed with gabapentin compared to placebo.

During the same time, Backonja reviewed the effect of gabapentin in 165 diabetic neuropathy patients and showed the result that pain reduction in the gabapentin group is greater (as measured with an 11-point Likert scale) in comparison to the placebo group. And the results were significant from 2 weeks of initiation of therapy and stayed significant during the eight weeks of study.

Patients in the treatment group also reported improvement in their quality of life. This medication was well tolerated in 67% of patients who received a maximum daily dosage of 3600 mg.

Treatment for Postherpetic neuralgia

Postherpetic neuralgia is a nerve disease occurs after an attack of herpes zoster infection. Herpes zoster or ‘shingles’ is a viral infection which affects the skin, especially sides of the chest, caused by varicella zoster virus. This is the same virus which causes chicken pox in children.

After an episode of herpes, the virus remains dormant in the nerve tissues of the body. This virus may become active when the immunity of the individual reduces or during convalescence after a major illness, resulting in blisters on the skin, known as shingles. It is accompanied with a rash which disappears without major consequences in about two to four weeks. Around 50% of individuals with shingles go on to develop post herpetic neuralgia (PHN) or after-shingles pain.

The neuralgia begins when the herpetic eruptions begin to heal. The pain appears usually in the affected dermatone or the affected nerve course and results in severe pain in the region which has the same nerve supply. The pain is a drawing, pricking type of intense pain, sometimes accompanied with burning sensation of the skin. The pain lasts from a few weeks to few months, rarely years.

 Causes

      • Severe rash within three days of shingles infection
      • A study shows that, 65% of patients were women
      • The chances of developing PHN, increases when the shingles occurs in persons over 50 years.
      • The incidence of herpes zoster is up to 15 times higher in HIV-infected patients than in uninfected persons, and as many as 25 percent of patients with Hodgkin’s lymphoma develop herpes zoster.
      • Blacks are one fourth as likely as whites to develop this condition.
      • Site of HZ involvement
        • Lower risk – Jaw, neck, sacral, and lumbar
        • Moderate risk – Thoracic
        • Highest risk – Trigeminal (especially ophthalmic division), brachial plexus.

Signs and symptoms:

    • A pain that continues for 3 months or more, after the healing of shingles, is defined as PHN.
    • PHN pain may be burning, aching, itching and sharp and the pain can be constant or it can come and go
    • The skin which was affected with blisters, may show scarring
    • The involved dermatome may show altered sensations, either hypersensitivity or reduced sensitivity.
    • In rare cases, where if the nerves involved also control muscle movement, the patient might also experience muscle weakness, tremor or paralysis

Postherpetic Neuralgia Treatment:

The conventional treatment is directed at pain control while waiting for the condition to resolve.  Pain therapy may include multiple interventions, such as topical medications, over-the-counter analgesics, tricyclic antidepressants,  anticonvulsants and a number of non medical modalities. Occasionally, narcotics may be required.

When it comes to treating postherpetic neuralgia, you may need to take a combination of medications to effectively manage your pain and other PHN symptoms. No single treatment plan is right for everyone—what medications you take will depend on your PHN symptoms.

While symptoms differ from person to person, for most people, PHN does improve over time. Researchers found that more than half of all patients with PHN stop experiencing pain within one year.1

Fortunately, during that period of intense pain and other symptoms, there are certain medications that you can take to significantly help control postherpetic neuralgia symptoms.

Before trying a prescription medication, your doctor will most likely want you to try an over-the counter (OTC) analgesic (painkiller) medication, such as acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs). These medications can help relieve pain and other PHN symptoms.

Tylenol is an example of acetaminophen, and Advil is an example of an NSAID you can take to help treat PHN.

Another OTC medication you may want to try for PHN is capsaicin cream. This cream—made from hot chili pepper seeds—is applied to the affected skin, and it can be helpful for reducing PHN-related pain. But this cream can be painful, so talk to your doctor about how much you should apply.

If these medications aren’t strong enough to treat your PHN symptoms, your doctor may suggest some of the prescription medications below to treat your postherpetic neuralgia.

    • Tricyclic antidepressants, such as amitriptyline (Elavil), nortriptyline (Pamelor), and desipramine (Norpramin) are effective at treating postherpetic neuralgia pain. Other classes of antidepressant are also helpful. All classes of antidepressant take a few weeks to start working.
    • Anticonvulsants, developed to control seizures, can help reduce the pain of PHN. These include gabapentin (Neurontin), carbamazepine (Tegretol) and pregabalin (Lyrica). Gabapentin enacarbil (Horizant) and gabapentin (Gralise) are approved by the FDA for the treatment of PHN in adults.
    • Anti-viral drugs valacyclovir and acyclovir are also becoming medications of choice for treating postherpetic neuralgia.
    • Lidocaine Patches for Postherpetic Neuralgia. Lidocaine patches are FDA-approved to treat PHN. The medication in the patch—lidocaine—can penetrate your skin and go to the nerves that are sending the pain signals. A benefit of lidocaine patches is that they don’t numb the skin.
    • Prescription capsaicin patches. These patches contain a very high concentration of the chili pepper extract capsaicin. The capsaicin patch Qutenza is applied in a doctor’s office for one hour every three months.

If you have severe pain and other medications don’t work for you, your doctor may want you to try an opioid.  Tramadol (eg, Ultram) is an example of a relatively weak opioid that can be used to help you manage PHN. Your doctor may have you try a weaker opioid first.  Opioids, such as morphine (MS Contin), oxycodone (OxyContin), and hydrocodone (Vidocin), are also used to treat moderate to severe pain of postherpetic neuralgia.

Homoeopathic Medicine:

Mezereum – For Postherpetic Neuralgia with Intense Burning

Mezereum is rated among the best medicines for postherpetic neuralgia. It is the best-suited prescription when postherpetic neuralgic pains are violent and attended with marked burning.  Mezereum is the most helpful among medicines for postherpetic neuralgia in postherpetic pains located in the face. The pain in the face may get worse while eating.

Warmth brings relief. Mezereum is also helpful during active herpes zoster where eruptions are present. The key symptoms to look out for before prescribing Mezereum during herpes zoster infection are violently itching vesicles with shining red areola and intense burning.

2. Ranunculus Bulbosus – For Pains coming in Paroxysms

Another of the prominently indicated medicines for postherpetic neuralgia is Ranunculus Bulbosus. It is indicated for sharp, shooting, postherpetic neuralgic pains that come in paroxysms.

It is also one of the top listed medicines for intercostal neuralgia following herpetic infection. Ranunculus Bulbosus is also indicated for herpes zoster when the vesicles eruptions are bluish in colour. The eruptions are attended with itching and burning symptoms which worsen on contact.

3. Rhus Tox – One of the best Medicines for Postherpetic Neuralgia

Rhus Tox also figures on the list of highly effective medicines for postherpetic neuralgia. It is one of the best medicines for postherpetic neuralgia where the pains are attended with marked restlessness. The skin is sensitive to cold air in such cases. In herpes zoster, Rhus Tox is the most preferred among medicines when the vesicles are yellowish with itching and stinging.

 

What Medicines Are Good for Treating Headaches ?

When headache pain has you in its grip, a fast-acting headache remedy is a top priority. Some headache remedies come in the form of medication. But there are also many ways to achieve natural headache relief. Feeling better may require a combination of treatments.

Medications

Headache remedies for migraine headaches are usually prescription drugs, such as:

    • beta blockers: atenolol (Tenormin); bisoprolol (Zebeta)
    • tricyclics: amitriptyline (Elavil, Endep); doxepin (Adapin, Sinequan)
    • calcium-channel blockers: verapamil (Calan, Isoptin, Verelan)
    • anticonvulsants: divalproex (Depakote); gabapentin (Neurontin); topimirate (Topamax)
    • triptans: almotriptan (Axert); eletriptan (Relpax); sumatriptan (Imitrex).

Triptans are meant for acute treatment of migraines, while all the other categories are meant for chronic prevention of migraines.

You must talk to a doctor in order to get a prescription. The drugs are not available over the counter.

While there are also prescription medications for other types of headaches, such as tension headaches or sinus headaches, over-the-counter (OTC) headache remedies may be enough to relieve the pain they bring. OTC pills are available without a prescription, but as the Harvard Medical School Special Health Report Headaches: Relieving and preventing migraines and other headaches notes, they are medications and must be used carefully.

  • Acetaminophen (Tylenol and others) is a generally safe non-aspirin headache remedy. But doses above 3 grams per day, especially when combined with alcohol, can cause potentially fatal liver damage. If you consume three or more alcoholic drinks a day, every day, don’t take acetaminophen.

  • Aspirin quells pain and may prevent migraine headaches in some people when taken regularly. Long-term side effects include kidney damage and gastrointestinal problems, such as stomach pain, heartburn, or nausea. Bleeding from the stomach can also occur, often in such minute quantities as to go unnoticed. However, over time anemia may result, causing fatigue— which, in turn, may increase the frequency of headaches. Avoid aspirin if you have reflux, gastritis, or ulcers.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) include aspirin, ibuprofen (Advil, Motrin, others), naproxen sodium (Aleve, Anaprox), and ketoprofen (Actron, Orudis, others). In some people, NSAIDs help prevent migraine headaches. Their long-term side effects are similar to those for aspirin.

Most healthy people who have mild to moderately painful headaches once in a while can take OTC headache remedies. But if you need to take an OTC painkiller several times a week, you should see your doctor.

Natural Headache Relief

Some people feel more comfortable seeking natural headache relief, in the form of plant-based or mineral supplements. Some of the most widely used preparations include:

      • Butterbur, an herb derived from plants in the genus Petasites
      • Feverfew, A daisy-like flower native to Europe
      • Peppermint oil, a culinary herb
      • Magnesium, a mineral
      • Coenzyme Q10 , an enzyme found in mitochondria, the energy factories of our cells
      • Vitamin B12

Consult your doctor before taking any of these supplements, as they can interact with medications to treat headaches or other conditions. The FDA does not regulate the effectiveness or safety of these products.

Activities that help

You may need more than just a pill for a headache remedy. Certain activities are also effective at relieving pain. For example, half of all headache sufferers in the United States use some type of mind-body technique to alleviate the pain. These include:

      • meditation
      • relaxation techniques, such as deep breathing
      • yoga
      • hypnosis, a state of deep relaxation that is similar to being in a trance
      • stress management

These mind-body therapies can help lower stress, a widely accepted headache trigger, and they also promote healthier lifestyle habits, such as getting adequate sleep, to keep headaches at bay.

Exercise, if performed regularly, is another natural headache remedy. It helps keep the heart and blood vessels healthy. It also boosts your mood, relieves stress, and helps prevent a host of ailments, such as high blood pressure.

Other natural headache relief

If your own natural headache remedies aren’t effective, consider alternatives, such as:

    1. Acupuncture: According to traditional Chinese beliefs, acupuncture works by affecting the flow of energy through pathways that run through the body.
    2. Psychotherapy: This can help you manage the effects that headaches have on your life, as well as the stresses and anxieties that may aggravate your pain.
    3. Physical therapy: This can provide relief for tension headaches and migraines by relaxing the tense muscles that commonly accompany tension and migraine headaches.

Seeking professional help

If headaches occur on a regular basis, it’s important to speak to your doctor, to see if an underlying condition is to blame, such as a medication side effect or a blood vessel abnormality.

Start with your primary care physician. You may be referred to a neurologist, who might order tests based on your symptoms. Once you have a diagnosis of the causes of your headaches, your doctor will be able to help you devise strategies for effective headache remedies.

Is Gabapentin ( Neurontin ) Addictive and How to Treat Gabapentin Addiction ?

Gabapentin is used with other medications to prevent and control seizures. It is also used to relieve nerve pain following shingles (a painful rash due to herpes zoster infection) in adults. Gabapentin is known as an anticonvulsant or antiepileptic drug.

Gabapentin, also known by the brand name Neurontin, is a prescription painkiller belonging to its own drug class, Gabapentinoids. It is considered an anti-convulsant, and is most commonly used to treat epilepsy, restless leg syndrome, hot flashes, and neuropathic pain. It is often used as a less-addictive alternative to opioids; however, Gabapentin addiction and abuse still occur in many patients.

Gabapentin has a similar chemical structure to Gamma-aminobutyric acid (GABA), the brain chemical which affects the body’s nervous system. It can produce feelings of relaxation and calmness, which can help with nerve pain, anxiety, and even poor sleep.

Gabapentin is prescribed to treat nerve pain, alcohol and cocaine withdrawals, restless leg syndrome, diabetic neuropathy, fibromyalgia, and seizures. It works by altering one’s calcium channels to reduce seizures and ease nerve pain. Some brand names of Gabapentin are Neurontin and Gralise. The drug’s known street names are “gabbies” or “johnnies.”

Dosages of Gabapentin

Adult and pediatric dosages:

Capsule

      • 100 mg
      • 300 mg
      • 400 mg

      • 600 mg (Gralise, Neurontin)
      • 800 mg (Neurontin)

Dosage Considerations – Should be Given as Follows:

Reducing the dose, discontinuing the drug, or substituting an alternative medication should be done gradually over a minimum of 1 week or longer.

Geritric dosing considerations:

Renal impairment is present, gabapentin dose reduction may be required, depending on renal function.

Partial Seizures

Neurontin

Adjunctive therapy for partial seizures with or without secondary generalization.

Creatinine clearance 15-29 mL/min: 200-700 mg once per day

Creatinine clearance less than 15 mL/min: 100-300 mg once per day

Hemodialysis (Creatinine clearance less than 15 mL/min):

Administer supplemental dose (range 125-350 mg) post hemodialysis, after each 4 hour dialysis interval; further dose reduction should be in proportion to Creatinine clearance (a Creatinine clearance of 7.5 mL/min should receive one-half daily post hemodialysis dose)

Renal impairment (Gralise):

Creatinine clearance is greater than or equal to 60 mL/min: 1800 mg daily with evening meal

Creatinine clearance 30-59 mL/min: 600-1800 mg daily with evening meal

Creatinine clearance greater than 30 mL/min or hemodialysis: Do not administer

In addition its potentially addictive nature, Gabapentin can cause suicidal thoughts, moods swings, and abrupt changes in a user’s behavior. It can also cause elevated blood pressure, fever, sleep problems, appetite changes, and chest pain.

Gabapentin may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

      • drowsiness
      • tiredness or weakness
      • dizziness
      • headache
      • uncontrollable shaking of a part of your body
      • double or blurred vision

Gabapentin Abuse

Gabapentin abuse tends to occur in people who already have an addiction to opioids or other drugs. The effects of Gabapentin intoxication have been described as a sense of calm, euphoria, and a high similar to marijuana.

A 2013 study in Kentucky found that of the 503 participants reporting illegal drug use, 15% reported using Gabapentin in addition to other drugs to get high in the previous six months. Another study, working with a sample of participants meant to represent the national population, found almost a quarter of patients with co-prescriptions of opioids and Gabapentin were getting more than three times their prescribed amount to supply their addiction. People using the drug without a prescription is a growing problem in many areas. Due to the drug’s legal status, this is difficult to address from a policing standpoint. States where Gabapentin abuse is becoming more common are beginning to classify the drug as a more strictly controlled substance.

Signs of a Gabapentin Overdose

Effects of excessive Gabapentin use include:

      • Drowsiness
      • Coordination problems
      • Tremors
      • Dizziness
      • Depression
      • Suicidal thoughts/behaviors
      • Changes in mood
      • Dizziness
      • Poor coordination
      • Forgetfulness
      • Anxiety
      • Difficulty speaking
      • Inability to feel pleasure

It is important to try to recognize these symptoms and to be wary of other red flags, such as the presence or abundance of pill bottles. These effects can be detrimental to one’s health, livelihood, and overall safety.

Many Gabapentin users in early recovery abuse Gabapentin because at high doses (800mg or more), they may experience a euphoric-like high that does not show up on drug screens. Gabapentin abusers typically take the drug in addition to opioids to produce their desired high, a dangerous and potentially deadly combination. It is possible to fatally overdose on Gabapentin, both on its own or in conjunction with other drugs. However, there is currently no antidote that can be administered to someone in the case of a Gabapentin overdose as there is with opioid overdoses. If you find a loved one showing signs of an overdose–drowsiness, muscle weakness, lethargy and drooping eyelids, diarrhea, and sedation—seek medical attention immediately.

Signs of Gabapentin Addiction

      • Lying about or exaggerating symptoms to doctors
      • Seeking out multiple doctors to get extra doses
      • Switching doctors after the original doctor refuses to continue prescribing the medication
      • Changes in social habits and/or circles
      • Changes in personal hygiene and grooming habits
      • Constant preoccupation with the drug
      • Unease at the thought of the drug being unavailable
      • Refusal to quit despite social, financial, or legal consequences
      • Failed attempts to quit

Treating a Gabapentin Addiction

Frequent and excessive use of Gabapentin can lead to a physical and psychological dependence on the drug. This is when someone becomes so accustomed to taking a drug that they need it to feel and function normally. Quitting a drug like Gabapentin cold turkey can be dangerous and induce several withdrawal symptoms of varying severity.

These include anxiety, insomnia, nausea, pain, and sweating. Quitting also increases one’s likelihood of having a seizure which can lead to personal injury or the development of medical problems and life-threatening emergencies. Trying to quit should be done at a rehab facility or with the guidance and supervision of a professional during a medical detox.
