Which statement is true about managing phenytoin therapy?

• A. Gingival hyperplasia may occur.
• B. All patients experience severe sedation.
• C. The drug cures epilepsy.
• D. It has no interactions.

Answer: (A)

A key point in managing phenytoin therapy is recognizing that gingival overgrowth can occur with long-term use. This happens because phenytoin can stimulate gingival fibroblasts and alter collagen turnover, and it’s more noticeable in patients with suboptimal dental hygiene. Because of this, the focus is on preventive dental care and oral hygiene—regular brushing, flossing, dental cleanings, and early dental consultations if gum enlargement is noticed. In some cases, if the overgrowth is troublesome or progressive, dose adjustments or a switch to a different antiseizure medication may be considered. Phenytoin does not cure epilepsy; it helps control seizures as part of ongoing treatment. Sedation is not experienced by all patients and varies with dose and individual response. It also has numerous drug interactions due to enzyme induction, so the idea that it has no interactions is inaccurate. Understanding these aspects helps guide monitoring, patient education, and collaborative care.
