For intravenous use only; fatal if given by other routes. To reduce the potential for fatal medication errors due to incorrect route of administration proper dilution, product labeling and packaging is necessary. Intravenous needle or catheter must be properly positioned before any vinCRIStine is injected, as leakage into the surrounding tissue 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.
