Oxcarbazepine is employed in the management of seizure disorders, targeting neuronal hyper‑excitability.

- Partial seizures: Reduces the frequency and severity of focal onset seizures. - Generalized tonic‑clonic seizures: Helps control convulsive episodes in epilepsy. - Lennox‑Gastaut syndrome: Provides adjunctive seizure control in this severe childhood epilepsy. - Bipolar disorder (off‑label): May stabilize mood in some patients, though not a primary indication. - Migraine prophylaxis (off‑label): Occasionally used to prevent migraine attacks. - Post‑traumatic epilepsy: May be considered to reduce seizure risk after brain injury.

Oxcarbazepine may cause a range of adverse reactions, most of which are mild to moderate and resolve with continued therapy or dose adjustment.

Common Side Effects: - Dizziness - Drowsiness - Headache - Nausea - Hyponatraemia (low blood sodium) - Rash

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Severe hyponatraemia with seizures or coma - Aplastic anemia - Liver function abnormalities - Blood dyscrasias such as agranulocytosis - Life‑threatening skin reactions (e.g., drug reaction with eosinophilia and systemic symptoms).

When prescribing Oxcarbazepine, clinicians should consider several safety aspects.

- Renal function: Adjust dose in patients with impaired clearance. - Hepatic function: Monitor liver enzymes in patients with liver disease. - Hyponatraemia risk: Check serum sodium regularly, especially in the elderly. - Pregnancy: Use only if the benefit outweighs potential fetal risk. - Concomitant drugs: Review for interactions that may affect sodium balance or cardiac rhythm. - Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Oxcarbazepine interacts with several medicines, requiring careful management.

Major Interactions (Avoid): - Carbamazepine: May increase risk of serious skin reactions. - Sodium valproate: Can exacerbate hyponatraemia. - Anticoagulants (e.g., warfarin): May reduce anticoagulant effect.

Moderate Interactions (Monitor Closely): - Oral contraceptives: May reduce hormonal efficacy. - SSRIs and SNRIs: Potential for additive hyponatraemia. - CYP3A4 inducers (e.g., rifampicin): May lower oxcarbazepine levels. - ACE inhibitors: Heightened risk of low sodium. - Diuretics: May compound hyponatraemia.
