Oral health effects

  • Increased bleeding (platelet inhibition)

    NSAIDs reversibly inhibit platelet function, modestly increasing bleeding during invasive procedures.

    Mechanism: Reversible COX-1 inhibition reduces thromboxane-mediated platelet aggregation.

    Clinical management: Usually minor; consider acetaminophen if bleeding is a concern; local hemostasis as needed.

  • Oral/GI mucosal ulceration & lichenoid reaction

    Associated with oral lichenoid drug reactions.

    Clinical management: Symptomatic care; biopsy persistent lichenoid lesions; limit duration; take with food.
