Special Precautions
Patient with chronic atrial fibrillation. Correct electrolyte imbalance (particularly hypomagnesaemia and hypokalaemia) before administration and during therapy. Patient taking digoxin, particularly when plasma digoxin levels are confirmed or suspected to be above the usual therapeutic range. Not recommended in patients who previously had polymorphic ventricular tachycardia (e.g. torsades de pointes). Elderly. Pregnancy and lactation. Monitoring Parameters Monitor patient with continuous ECG for at least 4 hours after infusion or until QTc returned to baseline; electrolytes.
Adverse Reactions
Significant: Reversible or complete heart block; nonsustained ventricular tachycardia (monomorphic or polymorphic). Cardiac disorders: Supraventricular tachycardia, atrioventricular block, ventricular extrasystoles, bundle branch block, bradycardia, tachycardia, palpitations. Gastrointestinal disorders: Nausea. Nervous system disorders: Headache. Vascular disorders: Hypotension, hypertension.
Potentially Fatal: Arrhythmias, especially sustained polymorphic ventricular tachycardia, usually with QT prolongation or torsades de pointes but occasionally without documented QT interval prolongation.
