Discontinue if interstitial lung disease or pulmonary fibrosis is suspected. Patients with CHF, bradyarrhythmias, electrolyte abnormalities: monitor ECG. Correct hypokalemia or hypomagnesemia prior to initiation; monitor periodically during therapy. Congenital long QT syndrome; avoid. Renal impairment. Avoid extravasation. Embryo-fetal toxicity.
