Indications
Indicated for the short-term inotropic treatment of low output states caused by congestive heart failure, cardiogenic shock, septic shock, or after cardiac surgery.

Warnings
To optimize hemodynamics, correct hypovolemia if needed
Clinical experience with dobutamine following myocardial infarction has been insufficient to establish safety of drug for this use; there is concern that any agent that increases contractile force and heart rate may increase size of infarction by intensifying ischemia, but not known whether dobutamine does so
Severe coronary artery disease (CAD)
Hypertension common; hypotension may also occur
May cause a marked increase in heart rate or blood pressure,especially systolic pressure; because dobutamine facilitates atrioventricular conduction, patients with atrial fibrillation are at risk of developing rapid ventricular response; in patients who have atrial fibrillation with rapid ventricular response, a digitalis preparation should be used prior to institution of therapy with dobutamine; patients with pre-existing hypertension appear to face an increased risk of developing an exaggerated pressure response
During administration of dobutamine, monitor blood pressure continuously; pulmonary wedge pressure and cardiac output should be monitored whenever possible to aid safe and effective infusion of dobutamine in 5% dextrose Injection, USP
Ventricular ectopy exacerbation may occur
