Lamictal

Lamotrigine, the active ingredient in Lamictal, is an anticonvulsant presented as an oral tablet for oral use. It is used to treat epilepsy, including partial and generalized seizures, and to provide maintenance therapy for bipolar disorder in adults. GNH USA supplies Lamictal as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Lamotrigine is an anticonvulsant that acts on neuronal excitability in several neurological and psychiatric conditions. - Epilepsy (partial seizures): reduces the frequency and severity of focal seizures. - Epilepsy (generalized seizures): helps control tonic‑clonic and absence seizures. - Bipolar disorder (maintenance): stabilises mood and prevents recurrence of depressive or manic episodes.

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

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

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 injury - Aseptic meningitis - Life‑threatening hypersensitivity reactions

When prescribing lamotrigine, clinicians should consider several safety measures. - Titration schedule: follow a gradual dose‑increase to minimise rash risk. - Concomitant valproate: monitor for increased lamotrigine plasma levels. - Pregnancy: potential unknown risks; discuss benefits and alternatives. - Renal or hepatic impairment: adjust dose as needed. - Discontinuation: avoid abrupt stop to reduce seizure recurrence. - Store at ambient temperature: keep below 25°C, in original packaging, protected from moisture.

Lamotrigine interacts with several medicines that can alter its plasma concentration.

Major Interactions (Avoid): - Valproic acid: markedly increases lamotrigine levels, raising toxicity risk. - Carbamazepine: significantly reduces lamotrigine concentrations, decreasing efficacy. - Phenytoin: lowers lamotrigine exposure, potentially compromising seizure control.

Moderate Interactions (Monitor Closely): - Oral contraceptives: may reduce lamotrigine levels, requiring dose adjustment. - Phenobarbital: decreases lamotrigine concentrations, necessitating monitoring. - Serotonergic agents: concurrent use may increase the risk of serotonin‑related effects.
