Levophed SF

Levophed SF Contraindications





Full Prescribing Info
Levophed SF should not be given to patients who are hypotensive from hypovolemia, except as an emergency measure to maintain coronary and cerebral artery perfusion until blood volume replacement therapy can be completed. If Levophed SF is continuously administered to maintain blood pressure in the absence of blood volume replacement, the following may occur: Severe peripheral and visceral vasoconstriction, decreased renal perfusion and urine output, poor systemic blood flow despite "normal" blood pressure, tissue hypoxia and lactate acidosis.
Levophed SF should not be given to patients with mesenteric or peripheral vascular thrombosis (because of the risk of increasing ischemia and extending the area of infarction) unless, in the opinion of the attending physician, the administration of Levophed SF is necessary as a life-saving procedure.
Cyclopropane and halothane anesthetics increase cardiac autonomic irritability and therefore seem to sensitize the myocardium to the action of IV administered epinephrine or norepinephrine. Hence, the use of Levophed SF during cyclopropane and halothane anesthesia is generally considered contraindicated because of the risk of producing ventricular tachycardia or fibrillation.
The same type of cardiac arrhythmias may result from the use of Levophed SF in patients with profound hypoxia or hypercarbia.
