Lamictal

Lamotrigine, the active ingredient in Lamictal, is a sodium channel blocker presented as a tablet for oral use. It treats epilepsy and bipolar disorder in adults and children as prescribed.

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

Lamotrigine is used in neurological and psychiatric conditions that involve abnormal neuronal firing.

Epilepsy: reduces the frequency and severity of seizures. Bipolar disorder: stabilises mood and helps prevent depressive episodes. Generalized seizures: assists in controlling tonic‑clonic seizure activity.

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

Common Side Effects: - Rash or mild skin irritation. - Headache. - Dizziness. - Nausea.

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Severe blood dyscrasias such as agranulocytosis. - Hepatic failure or significant liver enzyme elevation.

Before prescribing Lamotrigine, clinicians should consider several safety factors.

Pregnancy: Category B – use only when the benefit outweighs potential risk. Renal impairment: dose may need adjustment; monitor renal function. Hepatic impairment: monitor liver enzymes and adjust dose if necessary. Concomitant valproate: increased risk of rash; close monitoring required. Avoid abrupt discontinuation: may precipitate seizure recurrence. Store at ambient temperature: keep in the original container, protect from moisture.

Lamotrigine interacts with several medicines that can alter its plasma levels or increase toxicity.

Major Interactions (Avoid): - Valproic acid: raises lamotrigine concentrations, heightening rash risk. - Carbamazepine: lowers lamotrigine levels, potentially reducing efficacy. - Phenobarbital: decreases lamotrigine concentrations, may require dose increase.

Moderate Interactions (Monitor Closely): - Oral contraceptives: can increase lamotrigine levels; dose adjustments may be needed. - Serotonergic agents: monitor for signs of serotonin syndrome. - Other antiepileptics (e.g., phenytoin): may modify lamotrigine metabolism.
