What is Lamotrigine?

Lamotrigine, the active ingredient in Lamictal, is a sodium channel blocker presented as an oral tablet for oral use. It treats epilepsy and bipolar disorder by stabilising neuronal membranes and modulating neurotransmitter release.\n\nGNH India supplies Lamictal as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

What is Lamotrigine used for?

Lamotrigine is used in neurological and psychiatric conditions that involve abnormal neuronal excitability.\n\nEpilepsy: helps control focal and generalized seizures in patients with epilepsy.\nBipolar disorder: stabilises mood and reduces the frequency of depressive episodes in adults with bipolar disorder.

What are the side effects of Lamotrigine?

Lamotrigine may cause a range of adverse reactions, from mild to severe.\n\nCommon Side Effects:\n- Dizziness\n- Headache\n- Nausea\n- Rash\n- Insomnia\n- Blurred vision\n\nSerious or Rare Side Effects:\n- Stevens‑Johnson syndrome or toxic epidermal necrolysis\n- Severe skin reactions (e.g., exfoliative dermatitis)\n- Blood dyscrasias such as agranulocytosis\n- Hepatic failure\n- Aseptic meningitis

What precautions apply to Lamotrigine?

Before initiating therapy, consider the following safety measures.\n\nPregnancy: Category B; use only if benefits outweigh potential risks.\nRenal impairment: dose may require adjustment based on renal function.\nHistory of severe skin reactions: avoid use due to increased risk.\nConcomitant valproic acid: higher lamotrigine plasma levels, monitor for toxicity.\nMonitor blood counts: periodic CBC recommended during treatment.\nStore at ambient temperature: keep below 25°C, retain in original packaging, and protect from moisture.

What does Lamotrigine interact with?

Lamotrigine can interact with several medicines, altering its effectiveness or safety.\n\nMajor Interactions (Avoid):\n- Valproic acid: markedly increases lamotrigine levels, raising toxicity risk.\n- Carbamazepine: reduces lamotrigine concentrations, potentially diminishing seizure control.\n- Phenobarbital: lowers lamotrigine levels, may compromise efficacy.\n\nModerate Interactions (Monitor Closely):\n- Oral contraceptives: may decrease lamotrigine levels; monitor seizure control.\n- Serotonergic agents: potential for serotonin syndrome; observe for symptoms.

Frequently asked questions

What is Lamictal used for?+
Lamictal, whose active ingredient is lamotrigine, is prescribed for the management of epilepsy and for mood stabilization in bipolar disorder. In epilepsy it helps control both focal and generalized seizures, while in bipolar disorder it reduces the frequency of depressive episodes and helps maintain mood equilibrium.
How does lamotrigine work?+
Lamotrigine works by inhibiting voltage‑gated sodium channels on neuronal membranes. This action limits the rapid influx of sodium ions during an action potential, stabilising the membrane and decreasing the release of excitatory neurotransmitters such as glutamate, which underlies its antiepileptic and mood‑stabilising effects.
What is the usual dose of Lamictal?+
The dosage of Lamictal is individualized and must be determined by a qualified prescriber. Dosing depends on the specific indication, patient age, renal function, and any concomitant medications that may affect lamotrigine levels. Patients should follow the prescribing clinician’s instructions and not adjust the dose on their own.
Is Lamictal safe during pregnancy or breastfeeding?+
Lamotrigine is classified as Pregnancy Category B, indicating that animal studies have not shown risk but there are no adequate controlled studies in pregnant women. It may be used if the potential benefit justifies the potential risk. Limited data suggest it is excreted in breast milk; breastfeeding decisions should be made with a healthcare professional.
How do I order Lamictal from GNH USA?+
To place an order, submit an enquiry on the Lamictal product page at gnh-usa.com, specifying the required quantity. GNH USA supplies hospitals, pharmacies and procurement teams worldwide. After the request, the sales team will verify trade or institutional credentials, then provide pricing, availability, shipping details and any necessary import documentation.
How does Lamictal compare with carbamazepine?+
Both lamotrigine and carbamazepine are sodium channel blockers used for epilepsy, but they differ in safety and tolerability. Lamotrigine has a lower risk of drug‑induced hyponatremia and fewer cognitive side effects, while carbamazepine can induce hepatic enzymes, affecting the metabolism of other drugs. Choice depends on individual patient factors and physician judgment.
How should Lamictal be stored and handled?+
Lamictal tablets should be stored at ambient temperature, below 25 °C, in their original packaging to protect from moisture and light. Keep the product out of reach of children and do not use after the expiry date. No special refrigeration is required for this oral formulation.
How is Lamictal administered?+
Lamictal is taken orally, usually with or without food, as directed by the prescribing clinician. The tablets are swallowed whole with a glass of water. Dosing schedules may involve gradual titration to minimise the risk of skin reactions, and the exact regimen is set by the healthcare provider.
What are the most serious risks to watch for while taking Lamictal?+
The most serious adverse reactions include severe skin conditions such as Stevens‑Johnson syndrome and toxic epidermal necrolysis, which can be life‑threatening. Other rare but serious risks are blood dyscrasias, hepatic failure, and aseptic meningitis. Patients should seek immediate medical attention if they develop a widespread rash, fever, or unexplained symptoms.
Who should not use Lamictal?+
Lamictal should be avoided in individuals with a known hypersensitivity to lamotrigine or any component of the formulation. Patients with a history of severe cutaneous adverse reactions to other antiepileptic drugs should use it with caution, and it is contraindicated in those taking contraindicated enzyme‑inducing agents without proper dose adjustment.
