Important Safety Information

•

Serious rashes requiring hospitalization and discontinuation of treatment have been reported in association with the use of LAMICTAL, some of which have included Stevens-Johnson syndrome

Epilepsy clinical trials: The incidence of these rashes is approximately 0.8% (8/1000) in pediatric patients (age <16 years) receiving LAMICTAL as adjunctive therapy and 0.3% (3/1000) in adults on adjunctive therapy. In a prospectively followed cohort of 1983 pediatric patients taking adjunctive LAMICTAL, there was 1 rash-related death

•

In worldwide postmarketing experience, rare cases of toxic epidermal necrolysis and/or rash-related death have been reported in adult and pediatric patients, but their numbers are too few to permit a precise estimate of the rate

•

Hypersensitivity reactions, some fatal or life-threatening, have occurred in association with the use of LAMICTAL. It is important to note that early manifestations of hypersensitivity (eg, fever, lymphadenopathy) may be present even though a rash is not evident. If such signs or symptoms are present, the patients should be evaluated immediately. LAMICTAL should be discontinued if an alternative etiology cannot be established

•

Prior to initiation of treatment with LAMICTAL, the patient should be instructed that a rash or other signs or symptoms of hypersensitivity (eg, fever, lymphadenopathy) may herald a serious medical event and that the patient should report any such occurrence to a physician immediately

•

To avoid an increased risk of rash, the recommended initial dose and subsequent dose escalations of LAMICTAL should not be exceeded

•

LAMICTAL should ordinarily be discontinued at the first sign of rash, unless the rash is clearly not drug-related
