Oxcarbazepine — Anticonvulsant (sodium channel blocker). Study the mechanism, listed uses and warnings from the US label on one sourced card.
Generic name
Oxcarbazepine
Class
Anticonvulsant (sodium channel blocker)
Mechanism
Activity is mainly mediated by MHD. The precise anti-seizure mechanism is unknown; in-vitro studies indicate voltage-sensitive sodium-channel blockade that stabilizes hyperexcited membranes.
Used for
Partial-onset seizures: monotherapy or adjunctive treatment in adults; Partial-onset seizures: monotherapy in children aged 4 years and older; Partial-onset seizures: adjunctive treatment in children aged 2 years and older
Common side effects
Dizziness; Somnolence; Diplopia; Fatigue; Nausea
Warnings
Hyponatremia; Serious dermatological reactions; Cross-hypersensitivity to carbamazepine
Brand questions use only name pairings verified against the linked product source. Unverified pairings are withheld from these questions; the other study content remains available.
Label date: 20260812 · For learning, not clinical decisions. US label and brand information; always consult the current source.
Source snapshot checked: 2026-10-21. The source document and selected fields were compared. The complete card has not had an independent clinical review.
Mechanism: The exact analgesic and antiepileptic mechanisms are unknown. Gabapentin is structurally related to GABA but does not affect its binding, uptake or degradation. It binds the alpha-2-delta calcium-channel subunit in vitro; the relevance to therapeutic effects is unknown.
On both cards: Common side effects — Dizziness; Somnolence; Fatigue
Only on the Gabapentin card: Used for — Postherpetic neuralgia in adults; Adjunctive treatment of partial-onset seizures in adults and children aged 3 or older · Common side effects — Peripheral edema; Ataxia · Warnings — DRESS (multiorgan hypersensitivity); Respiratory depression with CNS depressants; Suicidal behavior and ideation · Interactions — Opioids; Antacids (aluminum/magnesium hydroxide)
Mechanism: Precise mechanism unknown; proposed inhibition of voltage-sensitive sodium channels, stabilizing membranes and reducing glutamate release.
On both cards: Common side effects — Dizziness; Diplopia; Nausea
Only on the Lamotrigine card: Used for — Adjunctive treatment of the specified seizure types from age 2; Conversion to monotherapy for partial-onset seizures from age 16 when switching from one of the specifically listed antiseizure medicines; Maintenance of bipolar I disorder in adults after standard treatment of an acute episode · Common side effects — Headache; Ataxia · Warnings — Hemophagocytic lymphohistiocytosis; Multiorgan hypersensitivity (DRESS); Cardiac rhythm abnormalities; blood dyscrasias · Interactions — Estrogen-containing oral contraceptives; Carbamazepine; Valproate
Mechanism: Clinical anticonvulsant and migraine-prevention mechanisms are unknown. Preclinical findings suggest contributions from sodium-channel blockade, enhanced activity at some GABA-A receptors, AMPA/kainate antagonism and carbonic-anhydrase inhibition.
On both cards: Common side effects — Dizziness; Fatigue · Interactions — Hormonal contraceptives
Only on the Topiramate card: Used for — Initial monotherapy or adjunctive treatment of partial-onset or primary generalized tonic-clonic seizures from age 2; Adjunctive treatment of Lennox-Gastaut seizures from age 2; Migraine prevention from age 12 · Common side effects — Paresthesia; Anorexia; Weight loss · Warnings — Acute myopia / secondary angle-closure glaucoma; Metabolic acidosis; kidney stones; Cognitive effects; fetal toxicity · Interactions — Phenytoin / carbamazepine; Valproic acid (hyperammonemia)
An item counts as shared only when both cards use the same wording. If a card does not list an item, that is not a statement that the effect never occurs.
