Carbamazepine

Anticonvulsant / mood stabilizer

Brand names: Tegretol

Oral health effects

  • Severe mucocutaneous reactions (SJS/TEN)

    Carbamazepine carries a notable risk of Stevens-Johnson syndrome / TEN (higher in certain HLA-B*1502 populations), with painful oral ulceration.

    Clinical management: Treat suspected SJS/TEN as an emergency; urgent referral.

  • Xerostomia / dysgeusia

    Dry mouth and altered taste reported.

    Clinical management: Symptomatic care; reinforce caries prevention.

  • Aplastic anemia / agranulocytosis (infection, ulceration, bleeding)

    Boxed warning: carbamazepine can cause aplastic anemia and agranulocytosis. Mouth ulcers, gingival infection, petechiae or gingival bleeding can be early signs.

    Clinical management: Ask about recent blood counts. Unexplained ulcers, gingival bleeding, petechiae or infection with fever warrant urgent referral for a blood count before invasive treatment.
