(vincristine sulfate) injection USP


Caution - This preparation should be administered by individuals experienced in the administration of VINCASAR PFS. It is extremely important that the intravenous needle or catheter be properly positioned before any vincristine is injected. Leakage into surrounding tissue during intravenous administration of VINCASAR PFS may cause considerable irritation. If extravasation occurs, the injection should be discontinued immediately, and any remaining portion of the dose should then be introduced into another vein. Local injection of hyaluronidase and the application of moderate heat to the area of leakage help disperse the drug and are thought to minimize discomfort and the possibility of cellulitis.


See OVERDOSAGE section for the treatment of patients given intrathecal VINCASAR PFS.
