Lamictal (Lamotrigine)

Lamotrigine works by blocking voltage‑gated sodium channels on neurons, which stabilises the neuronal membrane and reduces the release of excitatory neurotransmitters such as glutamate. This dampens abnormal electrical activity that contributes to seizures and mood swings.

The dose of lamotrigine is individualized by the prescribing clinician based on the patient’s age, indication, renal and hepatic function, and any concomitant medications. The prescriber determines the starting dose, titration schedule, and maintenance dose to achieve therapeutic effect while minimising risk.

Safety data for lamotrigine during pregnancy and lactation are limited. It is classified as a pregnancy category where benefits must outweigh potential risks. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternatives and risk management with their healthcare provider.

To order Lamictal, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and the necessary import documentation.

Compared with carbamazepine, another antiepileptic, lamotrigine has a lower risk of drug‑induced hyponatraemia and fewer cognitive side effects, but it requires a slower titration to avoid rash. Unlike valproic acid, lamotrigine is not associated with weight gain or teratogenicity, making it a preferred option for many patients with bipolar disorder.

Lamotrigine tablets should be stored at ambient temperature, below 25 °C, in their original container to protect from moisture and light. Keep the product out of reach of children and do not use after the expiry date printed on the packaging.

Lamotrigine is taken orally, usually with or without food, as a tablet. The exact dosing schedule—once or twice daily—depends on the prescriber’s instructions and the therapeutic indication. Swallow tablets whole; do not crush or chew unless specifically directed.

The most serious risks include severe skin reactions such as Stevens‑Johnson syndrome or toxic epidermal necrolysis, blood disorders like aplastic anemia, and hepatic failure. Patients should seek immediate medical attention if they develop a widespread rash, fever, unexplained bruising, or signs of liver dysfunction.

Lamotrigine is contraindicated in individuals with a known hypersensitivity to lamotrigine or any component of the formulation. Caution is also advised for patients with severe hepatic impairment, those taking interacting medications that markedly alter lamotrigine levels, and pregnant women unless the therapeutic benefit justifies potential risk.
