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, helping to control seizures and stabilize mood. GNH USA supplies Lamictal as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Lamotrigine is employed in neurological and psychiatric conditions where abnormal neuronal excitability is a key factor. - Epilepsy: reduces the frequency and severity of partial and generalized seizures. - Bipolar disorder (maintenance therapy): stabilises mood and helps prevent depressive and manic episodes. - Seizure disorders: controls various seizure types, improving overall seizure control.

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

Common Side Effects: - Dizziness: transient light‑headedness, especially at treatment initiation. - Headache: mild to moderate intensity, often resolves with continued therapy. - Nausea: gastrointestinal discomfort that may lessen over time. - Rash: mild skin irritation or maculopapular eruptions.

Serious or Rare Side Effects: - Stevens‑Johnson syndrome: severe skin detachment requiring immediate medical attention. - Toxic epidermal necrolysis: life‑threatening skin reaction with extensive epidermal loss. - Blood dyscrasias: agranulocytosis or aplastic anemia, presenting with fever or infection. - Hepatic failure: signs of jaundice, dark urine, or elevated liver enzymes. - Suicidal thoughts: new or worsening mood changes, especially in psychiatric patients. - Severe hypersensitivity: multi‑organ involvement such as hepatitis or nephritis.

Before initiating lamotrigine therapy, consider the following safety measures. - Monitor skin reactions: discontinue immediately if a rash develops and seek medical evaluation. - Check blood counts: periodic CBC monitoring is advised to detect hematologic abnormalities. - Assess hepatic function: liver enzymes should be measured before and during treatment. - Avoid abrupt discontinuation: taper the dose under physician supervision to reduce seizure risk. - Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Lamotrigine can interact with several medicines, altering its plasma concentration or increasing toxicity risk.

Major Interactions (Avoid): - Valproic acid: markedly raises lamotrigine levels, increasing risk of severe skin reactions. - Carbamazepine: reduces lamotrigine concentrations, potentially diminishing efficacy. - Phenobarbital: accelerates lamotrigine metabolism, leading to lower drug exposure.

Moderate Interactions (Monitor Closely): - Oral contraceptives: may increase lamotrigine clearance, requiring dose adjustment. - Serotonergic agents: combined use can heighten the chance of serotonin syndrome. - Other antiepileptics: concurrent therapy may necessitate careful dose titration and monitoring.
