Carbamazepine
Carbamazepine is an anticonvulsant used for selected seizure disorders and nerve pain, and in some settings for bipolar disorder. It has important genetic, blood, liver, sodium and interaction considerations.
Key points
- Carbamazepine is used for particular seizure types and Trigeminal Neuralgia; it can worsen some other seizure types.
- A new rash, mouth sores, fever or facial swelling can signal a severe reaction and needs immediate medical advice.
- Do not stop carbamazepine suddenly or switch formulation without guidance because seizures or mood symptoms may worsen.
Listings are for comparison and general information, not a personal recommendation; suitability and supply depend on diagnosis, clinician and pharmacy checks, monitoring and prescription requirements.
What carbamazepine is used for
Carbamazepine reduces some focal and generalised tonic-clonic seizures and can relieve the brief, severe facial pain of trigeminal neuralgia. Its use as a mood stabiliser depends on the clinical setting and local product information.
Important safety checks
Before and during treatment, clinicians may review blood counts, liver function and blood sodium. Genetic testing may be relevant for people with ancestry associated with a higher risk of severe skin reactions. Carbamazepine has many interactions, including with hormonal contraceptives, anticoagulants, some antibiotics, antifungals and other seizure medicines. Pregnancy planning requires specialist review.
When to seek urgent care
Get urgent help for a spreading or blistering rash, skin pain, mouth or eye sores, fever with facial swelling, unusual bruising, jaundice, severe confusion, suicidal thoughts or a marked increase in seizures. Severe unsteadiness, double vision, vomiting or drowsiness may indicate toxicity.
