Lamotrigine

Lamotrigine blocks voltage‑gated sodium channels on neurons, which reduces the rapid firing of nerve cells. This action lowers the release of excitatory neurotransmitters such as glutamate, thereby decreasing neuronal hyper‑excitability that contributes to seizures and mood instability.

The dose of lamotrigine is individualized and must be set by a qualified prescriber. Starting doses are typically low and are increased gradually based on the patient’s response, concomitant medications, and tolerability. Patients should follow the dosing schedule provided by their healthcare professional.

Data on lamotrigine use in pregnancy are limited, and the drug crosses the placenta. It may be continued if the benefits outweigh potential risks, but close monitoring is advised. Lamotrigine is excreted in breast milk; breastfeeding decisions should be made in consultation with a physician.

To request lamotrigine, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Compared with carbamazepine or valproic acid, lamotrigine has a lower risk of weight gain and sedation but requires careful titration to avoid skin reactions. Its interaction profile differs; for example, valproic acid markedly raises lamotrigine levels, while carbamazepine reduces them, necessitating dose adjustments.

Lamotrigine tablets should be stored at room temperature, below 25 °C, in the original container to protect from moisture and light. Keep the product out of reach of children and do not use if the packaging is damaged.

Lamotrigine is taken orally, usually as a tablet that should be swallowed whole with water. It can be taken with or without food, but consistency with meals helps maintain stable absorption. Patients should not crush or chew the tablets unless specifically instructed.

The most serious risks include severe skin reactions such as Stevens‑Johnson syndrome or toxic epidermal necrolysis, blood disorders like agranulocytosis, and rare cases of hepatic failure or aseptic meningitis. Immediate medical attention is required if a rash or systemic symptoms develop.

Lamotrigine should not be used by individuals with a known hypersensitivity to the drug or any of its components. Patients with a history of severe rash (e.g., Stevens‑Johnson syndrome) from previous lamotrigine exposure should also avoid it. Caution is advised in those with significant hepatic impairment.
