The incidence of these rashes, which have included Stevens-Johnson syndrome, is approximately 0.8% (8 per 1,000) in pediatric patients (aged 2 to 16 years) receiving LAMICTAL as adjunctive therapy for epilepsy and 0.3%. Stevens-Johnson Syndrome is a rare but serious condition in which the skin and mucus membranes -- the moist surfaces in the mouth, nose and eyes -- react severely to a medication or infection. Lamotrigine comes as a tablet, an extended-release tablet, an orally disintegrating tablet (dissolves in the mouth and can be swallowed without water), and a chewable dispersible (can be chewed or dissolved in liquid) tablet to take by mouth with or without food.
