Lamictal

Lamotrigine, the active ingredient in Lamictal, is an anticonvulsant presented as an oral tablet for oral use. It treats epilepsy and bipolar disorder in adults and children as appropriate.

GNH USA supplies Lamictal as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Lamotrigine is used in the management of seizure disorders and mood stabilization.

Epilepsy: Reduces the frequency and severity of both focal and generalized seizures. Bipolar disorder: Helps prevent recurrence of depressive and manic episodes, supporting long‑term mood stability.

Lamotrigine may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Dizziness - Headache - Nausea or vomiting - Skin rash - Blurred vision - Insomnia

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Severe skin reactions (e.g., bullous eruptions) - Blood dyscrasias such as agranulocytosis - Hepatic failure - Suicidal thoughts or behavior - Severe hypersensitivity reactions

Before initiating lamotrigine therapy, consider the following safety measures.

Pregnancy: Use only if the potential benefit justifies the potential risk to the fetus. Renal impairment: Dose may require adjustment based on renal function. History of severe skin reactions: Avoid use in patients with prior Stevens‑Johnson syndrome. Concomitant valproic acid: Increases lamotrigine levels and risk of rash; monitor closely. Monitoring: Observe for signs of hypersensitivity or severe skin reactions during titration. Store at ambient temperature: keep in the original container, protect from moisture and light.

Lamotrigine can interact with several medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid): - Valproic acid: Increases lamotrigine concentrations, raising the risk of severe rash. - Carbamazepine: Decreases lamotrigine levels, potentially reducing seizure control. - Phenobarbital: Lowers lamotrigine exposure, may require dose increase.

Moderate Interactions (Monitor Closely): - Oral contraceptives: May reduce lamotrigine levels; dose adjustments may be needed. - Other antiepileptic drugs (e.g., phenytoin, primidone): May affect lamotrigine metabolism. - Serotonergic agents: Potential for additive central nervous system effects.
