Tofacitinib in Patients With Amyotrophic Lateral Sclerosis

All patients should be closely monitored for signs and symptoms of infection during and after treatment with tofacitinib tablets. If a patient develops a severe infection, opportunistic infection, or sepsis, medication should be discontinued. During treatment, patients with lymphocyte counts \< 500 cells/mm\^3 or ANC \< 500 cells/mm\^3 confirmed by repeated testing should be stopped. When 500≤ANC≤1000 cells/mm\^3, administration should be interrupted, and if ANC returns to more than 1000 cells/mm\^3, administration should be resumed. When hemoglobin \< 8 g/dL or decreases by more than 2 g/dL, administration should be interrupted until hemoglobin values return to normal.
