Neumega (Oprelvekin) was approved in November, 1997 for use in adults with nonmyeloid malignancies who are at high risk for severe thrombocytopenia due to myelosuppressive chemotherapy.
Neumega is indicated for the prevention of severe thrombocytopenia and for the reduction in the proportion of patients requiring platelet transfusions. Neumega is not indicated for use in children or in patients receiving myeloablative chemotherapy.
New adverse event information from post-marketing reports has been added to the
Neumega prescription information. The following statements have been added to the WARNINGS section:
“In the post-marketing setting, ventricular arrhythmias have been reported, generally occurring within two to seven days of initiation of treatment.”
“Changes in visual acuity and/or visual field defects ranging from blurred vision to blindness can occur in patients with papilledema taking Neumega.”
The post-marketing reports of the ADVERSE REACTIONS sections has been revised and reformatted to include reports of optic neuropathy and ventricular arrthymias. In addition to incorporating the new adverse event information into product labeling, Wyeth Pharmaceuticals Inc. (Philadelphia, Pennsylvania) has committed to an evaluation of the effects of Neumega on the QT interval.
