Lamotrigine is an anticonvulsant that acts on neuronal excitability to control seizure activity and stabilize mood.

Partial seizures: reduces seizure frequency in focal onset epilepsy. Generalized tonic‑clonic seizures: decreases occurrence of convulsive seizures. Bipolar disorder: maintenance therapy to prevent recurrence of mood episodes. Seizure prophylaxis: used as adjunct therapy to lower overall seizure burden.

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

Common Side Effects: - Dizziness - Headache - Nausea - Mild skin rash

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Aseptic meningitis - Blood dyscrasias such as agranulocytosis

When prescribing lamotrigine, several safety considerations should be observed to minimize risk.

Pregnancy: limited data; use only if benefit outweighs risk. Renal impairment: monitor renal function and adjust dose if necessary. Hepatic impairment: use caution and consider dose modification. Concomitant valproate: may increase lamotrigine levels; monitor closely. Discontinuation: avoid abrupt stopping to prevent seizure recurrence. Store at ambient temperature below 25°C: keep in original packaging, protect from moisture.

Lamotrigine interacts with several medicines, requiring attention to avoid altered drug exposure.

Major Interactions (Avoid): - Valproic acid: markedly increases lamotrigine concentrations, risk of toxicity. - Carbamazepine: reduces lamotrigine levels, may diminish efficacy. - Phenobarbital: lowers lamotrigine concentrations, may require dose increase.

Moderate Interactions (Monitor Closely): - Oral contraceptives: decrease lamotrigine levels, may need dose adjustment. - Serotonergic agents: potential for serotonin syndrome, monitor symptoms. - Other antiepileptics (e.g., phenytoin): may reduce lamotrigine exposure.
