Precautions and Warnings

Hepatic Injury: Cases of drug-induced liver injury, some of which were fatal, have been reported in patients taking Extals 50 mg. Asymptomatic elevations of hepatic transaminases have also been reported, and in some patients have recurred upon rechallenge with Extals 50 mg.In clinical studies, the incidence of elevations in hepatic transaminases was greater in Extals 50 mgtreated patients than placebo-treated patients. The incidence of elevations of ALT above 5 times the upper limit of normal (ULN) was 2percent in Extals 50 mg-treated patients. Maximum increases in ALT occurred within 3 months after starting Extals 50 mg. About 50percent and 8percent of Extals 50 mgtreated patients in pooled Studies 1 and 2, had at least one elevated ALT level above ULN and above 3 times ULN, respectively Monitor patients for signs and symptoms of hepatic injury, every month for the first 3 months of treatment, and periodically thereafter. The use of Extals 50 mg is not recommended if patients develop hepatic transaminases levels greater than 5 times the ULN. Discontinue Extals 50 mg if there is evidence of liver dysfunction (e.g., elevated bilirubin).Neutropenia: Cases of severe neutropenia (absolute neutrophil count less than 500 per mm3) within the first 2 months of Extals 50 mg treatment have been reported. Advise patients to report febrile illnesses.Interstitial Lung Disease: Interstitial lung disease, including hypersensitivity pneumonitis, has occurred in patients taking Extals 50 mg.
