Lamictal

Lamotrigine, the active ingredient in Lamictal, is an Anticonvulsant presented as an oral tablet for oral use. It is indicated for the treatment of epilepsy and for maintenance therapy in bipolar disorder, helping to control seizures and stabilize mood in affected patients.

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

Lamotrigine is an anticonvulsant that modulates neuronal excitability in seizure disorders and mood disorders.

- Epilepsy: reduces the frequency and severity of partial and generalized seizures. - Bipolar disorder: provides mood stabilization and helps prevent depressive and manic episodes. - Adjunct seizure therapy: used in combination with other antiepileptic drugs when monotherapy is insufficient.

Lamotrigine may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Dizziness - Headache - Nausea or vomiting - Rash (mild) - Insomnia - Blurred vision

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 - Anaphylactic reactions - Multiorgan hypersensitivity

Before initiating lamotrigine therapy, consider the following safety measures.

- Pregnancy: Category B; discuss potential risks and benefits with a healthcare professional. - Rash monitoring: discontinue immediately if a severe or spreading rash develops. - Discontinuation: avoid abrupt cessation to reduce seizure recurrence. - Hepatic impairment: use caution and consider dose adjustment. - Enzyme inducers: adjust dose when co‑administered with strong inducers such as carbamazepine. - Store at ambient temperature: keep in the original packaging, protect from moisture and excessive heat.

Lamotrigine interacts with several drugs that can alter its plasma concentrations.

Major Interactions (Avoid): - Valproic acid: markedly increases lamotrigine levels, raising risk of toxicity. - Carbamazepine: significantly reduces lamotrigine concentrations, potentially decreasing efficacy. - Phenytoin: lowers lamotrigine levels, requiring dose adjustment.

Moderate Interactions (Monitor Closely): - Oral contraceptives: may decrease lamotrigine levels, necessitating monitoring. - Other antiepileptics (e.g., phenobarbital, topiramate): can modestly affect lamotrigine exposure. - Serotonergic agents: observe for signs of serotonin syndrome when combined.
