Buy Generic Neurontin (Gabapentin) Online – More Details You Should Know

What is Neurontin?

Neurontin, known by its generic name gabapentin, is a pharmaceutical medication that belongs to the class of anticonvulsant drugs. It is specifically designed to help manage and control seizures in individuals with epilepsy. However, Neurontin is not limited to just one use. Its versatile nature allows it to be prescribed for a range of conditions, including neuropathic pain, restless legs syndrome, and even certain psychiatric disorders.

It operates by altering the activity of calcium channels in the central nervous system, resulting in a decrease in the release of certain excitatory neurotransmitters. This modulation helps to regulate abnormal neuronal firing and may contribute to its anticonvulsant and analgesic properties. Additionally, it influences the availability of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter that promotes a calming effect on the brain.


Neurontin (gabapentin) is classified as an anticonvulsant or antiepileptic medication. Anticonvulsants are a class of drugs primarily used to manage seizures and prevent their recurrence. While Neurontin was initially developed and approved for the treatment of epilepsy, it has also shown efficacy in other conditions such as neuropathic pain and certain psychiatric disorders. Additionally, this drug may be used off-label for various indications, but its primary classification remains as an anticonvulsant.

What is neurontin generic name?

The generic name for Neurontin is gabapentin. Gabapentin is an anticonvulsant medication that is structurally related to the neurotransmitter gamma-aminobutyric acid (GABA). It is thought to work by modulating calcium channels and increasing the availability of GABA, an inhibitory neurotransmitter, in the central nervous system. Gabapentin is commonly prescribed for the treatment of seizures, neuropathic pain, and other conditions as determined by healthcare professionals. It may be available in various formulations, such as capsules, tablets, or oral solution.

What is Neurontin used for?

Neurontin (gabapentin) is prescribed for various medical conditions and can be used to manage different symptoms. Some of the common cases in which it may be prescribed include:

  1. Epilepsy: Neurontin is FDA-approved for the treatment of partial seizures and as an adjunctive therapy for generalized seizures in adults and children aged 3 years and older.
  2. Neuropathic Pain: Neurontin is commonly prescribed for the management of neuropathic pain conditions, such as diabetic neuropathy, postherpetic neuralgia (pain following shingles), and peripheral neuropathy.
  3. Fibromyalgia: Neurontin may be prescribed as an off-label treatment for fibromyalgia, a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, and tender points.
  4. Restless Legs Syndrome (RLS): This drug can be used off-label to alleviate the uncomfortable sensations and urge to move associated with RLS, a neurological disorder affecting the legs.
  5. Migraine Prevention: Neurontin may be prescribed off-label for the prevention of migraines, particularly in individuals who experience frequent or severe migraine attacks.
  6. Anxiety Disorders: In certain cases, Neurontin may be prescribed off-label to help manage symptoms of anxiety disorders, such as generalized anxiety disorder (GAD) and social anxiety disorder (SAD).
  7. Off-Label Uses: Neurontin is sometimes prescribed off-label for other conditions, including bipolar disorder, alcohol withdrawal, trigeminal neuralgia, and certain psychiatric disorders.

How does Neurontin work?

Here is a list outlining the mechanism of action of Neurontin (gabapentin):

  1. Modulation of Calcium Channels: It exerts its effects by binding to a specific subunit (α2δ-1) of calcium channels in the central nervous system. This binding reduces the influx of calcium ions into neurons, leading to a decrease in the release of various excitatory neurotransmitters.
  2. Inhibition of Excitatory Neurotransmitter Release: By inhibiting the release of excitatory neurotransmitters, such as glutamate, this medication helps to dampen abnormal neuronal activity. This mechanism contributes to its antiepileptic and analgesic properties.
  3. Increased GABA Availability: This drug increases the concentration of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain. This enhanced availability of GABA helps to further reduce neuronal excitability and promote a calming effect.
  4. Altered Neurotransmitter Signaling: The very product affects various neurotransmitters involved in pain perception, including norepinephrine and substance P. By modulating their release and signaling pathways, it may provide relief from neuropathic pain.
  5. Attenuation of Central Sensitization: Neurontin may prevent or reduce central sensitization, a process where the central nervous system becomes more sensitive to pain signals over time. By inhibiting abnormal neuronal firing and modulating pain pathways, Neurontin can help mitigate this phenomenon.

How long does it take Neurontin to work?

The onset of action of Neurontin (gabapentin) can vary among individuals and depends on several factors. While some individuals may experience relief from symptoms relatively quickly, for others, it may take some time for the medication to exert its therapeutic effects.

The mechanism of action involves modulating certain neurotransmitters in the brain, specifically targeting the calcium channels. By doing so, it aims to reduce abnormal neuronal firing and dampen the transmission of pain signals. However, the precise time it takes for Neurontin to work can differ from person to person.

In some cases, individuals may notice an improvement in their symptoms within a few days or weeks of starting the treatment. This could manifest as a reduction in pain intensity, a decrease in seizure frequency, or an improvement in neuropathic symptoms. However, it’s essential to note that the therapeutic effects may continue to develop over an extended period.

How long does Neurontin stay in your system?

The duration of time that Neurontin (gabapentin) remains in the body can vary among individuals. On average, Neurontin has a half-life of approximately 5 to 7 hours in adults with normal kidney function. A medication’s half-life refers to the time it takes for half of the drug to be eliminated from the body.

Based on the half-life of Neurontin, it can take approximately 1 to 2 days for the medication to be completely eliminated from the body after discontinuation. However, it’s important to note that individual factors such as metabolism, kidney function, and dosage may influence how long Neurontin stays in the system.
