Generic Gabapentin Information

Introduction

Gabapentin is an oral medication classified within the pain‑relief group. It is widely prescribed in Hong Kong for neuropathic pain, post‑herpetic neuralgia and as an adjunct therapy for certain seizure disorders. The active compound, gabapentin, is a structural analogue of the neurotransmitter gamma‑aminobutyric acid (GABA). Although its primary indication is pain modulation, clinicians also use it for restless‑legs syndrome, fibromyalgia and off‑label anxiety management when evidence supports benefit.

What is Gabapentin?

Gabapentin is the generic version of Neurontin, the original brand developed by Pfizer. Both contain the same active compound, gabapentin, and provide equivalent therapeutic effects. Our online pharmacy offers this generic alternative as a cost‑effective treatment option, complying with Hong Kong’s regulatory standards for safety and quality. The medication is marketed as a capsule or tablet formulation and belongs to the class of γ‑aminobutyric acid (GABA) analogues, though it does not bind to GABA receptors.

How Gabapentin Works

Gabapentin binds selectively to the α₂δ subunit of voltage‑gated calcium channels in neuronal membranes. This binding reduces calcium influx during depolarisation, thereby decreasing the release of excitatory neurotransmitters such as glutamate, substance P and norepinephrine. The net effect is a dampening of abnormal neuronal firing that underlies neuropathic pain and certain seizure activity. Oral absorption is rapid, with peak plasma concentrations occurring 2–4 hours after dosing. The drug is not extensively metabolised; it is eliminated unchanged by renal excretion, giving a half‑life of about 5–7 hours in individuals with normal kidney function.

Conditions Treated with Gabapentin

• Post‑herpetic neuralgia – persistent pain following shingles; a common indication approved by the Hong Kong Department of Health.
• Diabetic peripheral neuropathy – sensory pain in the feet and hands of patients with type 2 diabetes, a growing concern in Hong Kong’s aging population.
• Partial seizures – adjunct therapy for focal onset seizures when first‑line antiepileptics are insufficient.
• Restless‑legs syndrome (RLS) – improves uncomfortable leg sensations and urge to move, especially in patients who cannot tolerate dopamine agonists.
• Fibromyalgia – off‑label use supported by meta‑analyses showing modest pain reduction.

These conditions share a pathophysiology of hyper‑excitable peripheral or central neurons, which gabapentin’s calcium‑channel modulation directly addresses.

Who is Gabapentin For?

• Adults with confirmed neuropathic pain conditions (e.g., post‑herpetic neuralgia, diabetic neuropathy).
• Patients diagnosed with focal onset seizures who need adjunctive therapy.
• Individuals experiencing moderate to severe RLS symptoms unresponsive to non‑pharmacologic measures.
• Patients with fibromyalgia who have not achieved adequate relief from first‑line analgesics.

Contra‑indications include severe renal impairment (creatinine clearance < 30 mL/min) where dose adjustment is required, known hypersensitivity to gabapentin, and pregnancy without medical supervision. Caution is advised in elderly patients, those with a history of substance misuse, and patients taking central nervous system depressants.

Risks, Side Effects, and Interactions

Common

• Dizziness or light‑headedness
• Somnolence (sleepiness)
• Peripheral oedema (swelling of ankles/feet)
• Coordination disturbances (ataxia)

Rare

• Visual disturbances (blurred vision, double vision)
• Mood changes (depression, irritability)
• Gastrointestinal upset (nausea, constipation)

Serious

• Severe allergic reactions (rash, Stevens‑Johnson syndrome)
• Respiratory depression when combined with opioids or other CNS depressants
• Suicidal ideation or behavior, particularly in patients with psychiatric disorders

Drug–Drug Interactions

• Opioids (e.g., morphine, oxycodone) – additive sedation and respiratory risk.
• Antacids containing aluminum or magnesium – may reduce gabapentin absorption; separate dosing by at least 2 hours.
• CNS depressants (benzodiazepines, barbiturates, alcohol) – increase risk of profound drowsiness and impaired cognition.
• Renal‑clearing drugs (e.g., aminoglycosides, NSAIDs) – may exacerbate renal function decline, requiring dose adjustment.

Patients should disclose all current medications, including over‑the‑counter products and supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose for neuropathic pain: 300 mg once daily, titrated by 300 mg every 3‑4 days to a usual maintenance range of 900–180 mg per day, divided into three doses.
• Seizure adjunct: typical adult dose starts at 300 mg three times daily, adjusted up to 180 mg/day based on response and tolerability.
• Renal impairment: dose reductions are recommended (e.g., 50 % reduction for creatinine clearance 30‑60 mL/min).

Missed dose – take the missed tablet as soon as remembered unless it is near the time of the next scheduled dose; do not double‑dose.

Overdose – symptoms may include profound drowsiness, respiratory depression and ataxia. Seek immediate medical attention; supportive care is the mainstay of treatment, as there is no specific antidote.

Precautions – take with or without food; avoid alcohol; monitor renal function regularly, especially in older adults or those with diabetes.

FAQ

• Is gabapentin available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is Neurontin, while generic gabapentin contains the identical active compound and is widely available at lower cost through our online pharmacy.

• Can gabapentin be stored at room temperature, or does it require refrigeration?
  Gabapentin tablets should be kept at a controlled room temperature (15‑30 °C). It does not require refrigeration but must be protected from excess heat, moisture and direct sunlight.

• What does the gabapentin tablet look like, and are there any distinguishing marks?
  Generic tablets are typically round, white to off‑white, and may bear a score line for splitting. The imprint varies by manufacturer; common markings include “GAB‑300” or “G‑500” indicating strength.

• Are there any special considerations for travelling with gabapentin to or from Hong Kong?
  Travelers should keep the medication in its original packaging with a copy of the prescription or a doctor's note, carry it in hand luggage, and be aware of customs limits for personal import (generally up to a 30‑day supply).

• Does gabapentin affect drug testing for employment or sports?
  Gabapentin is not a prohibited substance in most standard workplace drug screens. However, certain sports governing bodies may list it under monitored substances; athletes should verify specific regulations.

• How does gabapentin differ from other GABA analogues like pregabalin?
  Both drugs bind to the α₂δ calcium‑channel subunit, but pregabalin has higher affinity, a faster onset, and is typically prescribed when gabapentin is insufficient. Dosage forms and renal clearance also differ.

• Can gabapentin be taken safely with herbal supplements such as valerian or kava?
  Combining gabapentin with other CNS depressants, including some herbal products, can increase sedation and dizziness. Patients should discuss any supplements with their healthcare provider before use.

• What are the legal limits for personal import of prescription medicines into Hong Kong?
  Hong Kong allows individuals to import a 30‑day supply of prescription medication for personal use, provided it is for a legitimate medical need and accompanied by a valid prescription or doctor’s letter.

• Is there a risk of dependence or withdrawal when stopping gabapentin?
  Abrupt discontinuation after long‑term use may lead to rebound anxiety, insomnia, or increased pain. A gradual taper, under medical supervision, reduces the likelihood of withdrawal symptoms.

• Why might some patients experience swelling of the ankles while on gabapentin?
  Peripheral oedema occurs due to fluid retention, a known side effect of gabapentin. It is usually mild and resolves with dose adjustment or diuretic therapy if necessary.
