Lamotrigin ”viatris”

Lamotrigine, the active ingredient in Lamotrigin, is an Anticonvulsant presented as a tablet for oral use. It is used to treat various seizure types and bipolar disorder in adults and children, stabilizing neuronal activity and mood swings. The medication works by inhibiting voltage‑gated sodium channels and reducing excessive glutamate release.

GNH USA supplies Lamotrigin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company follows stringent quality standards and provides reliable global distribution.

Lamotrigine is an anticonvulsant indicated for several seizure disorders and mood stabilization. - Epilepsy: reduces the frequency and severity of both focal and generalized seizures. - Bipolar disorder: helps prevent mood episodes and stabilizes emotional swings. - Partial seizures: decreases occurrence of focal onset seizures with or without secondary generalization. - Generalized tonic‑clonic seizures: lowers the risk of convulsive episodes in affected patients.

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

Common Side Effects: - Dizziness - Headache - Nausea or vomiting - Rash or mild skin irritation - Blurred vision - Fatigue

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis (severe skin reactions) - Blood dyscrasias such as agranulocytosis, aplastic anemia, or leukopenia - Hepatic failure or severe liver injury - Suicidal thoughts or behavior - Severe hypersensitivity reactions including anaphylaxis

When prescribing lamotrigine, several safety considerations should be observed. - Dose titration: increase gradually to reduce risk of skin reactions. - Blood monitoring: check complete blood count periodically for hematologic abnormalities. - Drug interactions: adjust dose when co‑administered with enzyme‑inducing antiepileptics. - Hepatic impairment: use caution and consider lower initial dose. - Pregnancy: potential risks are unknown; evaluate benefit‑risk before use. - Store at below 25°C: keep in original packaging, protect from moisture and light.

Lamotrigine’s plasma levels can be altered by several concomitant medicines.

Major Interactions (Avoid): - Carbamazepine, phenytoin, phenobarbital: strong enzyme inducers that markedly lower lamotrigine concentrations. - Valproic acid (high dose): can increase lamotrigine levels leading to toxicity.

Moderate Interactions (Monitor Closely): - Oral contraceptives: lamotrigine may reduce hormonal efficacy, requiring alternative contraception. - Serotonergic agents (e.g., SSRIs, SNRIs): potential for increased serotonergic effects. - Other antiepileptics (e.g., topiramate, zonisamide): may require dose adjustments.
