Tarceva monotherapy is indicated for the treatment of patients who have locally advanced or metastic non-small cell lung cancer after failure of at least one prior chemotherapy regimen.

SJS/TEN is a severe adverse reaction that has been linked to more than 200 medications. It is most commonly associated with ibuprofen, antibiotics and anti-seizure medication. SJS/TEN is rare but life-threatening, causing a rash to form on the skin. The rash blisters over and the skin peels off in sheets. In some, as much as 90 percent of the skin can peel away, leaving the victim susceptible to infection. Patients are often treated in burn units and put into a drug-induced coma to help ward off infection. Blisters also can form on the mucus membranes, such as the eyes, mouth and internal organs, causing dehydrations and ocular problems.
