In the 1999 review, James Ruble and Fumisuke Matsuo discussed the incidence, mechanisms, and management of cutaneous drug reactions (CDRs) induced by anticonvulsants. They noted that while CDRs are relatively uncommon, they can be severe and unpredictable. Mild reactions like exanthems and urticaria are most common, but severe reactions require careful management, potentially in burn centers, and may involve immunosuppressive therapy. The review also addressed specific reactions such as alopecia, pigmentation changes, and various severe skin conditions like erythema multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). Alopecia caused by valproic acid typically reverses after discontinuation of the drug, and treatment options are limited. The document highlighted the importance of recognizing and managing CDRs to optimize patient care, despite the difficulty in establishing specific incidence rates due to limitations in clinical reporting.
