Warnings
Use caution in patients with cardiac disease, angina (especially with history of CAD) or that are receiving drugs that sensitize the myocardium; treatment may induce cardiac arrhythmias
Pulmonary edema may occur as the result of cardiac stimulation and peripheral constriction
Decreased urine output may occur as the result of renal blood vessel constriction
Use caution in cerebrovascular insufficiency
Use with caution in patients with hypertension, diabetes mellitus, thyroid disease, prostatic hypertrophy, geriatric patients, pregnancy, and previous hospitalization for asthma
Rapid IV administration, although necessary in pulesless arrest, may cause death from cerebrovascular hemorrhage or cardiac arrhythmias
Patients that are sulfite-sensitive, should still be treated during a serious allergic reaction or other emergency even if products available contain sulfites
May cause worsening of symptoms in patients with Parkinson disease
Avoid extravasation; ensure proper needle or catheter placement prior to and during infusion
Correct blood volume depletion before administering any vasopressor
Pregnancy and Lactation
During pregnancy, anaphylaxis can be catastrophic and can lead to hypoxic-ischemic encephalopathy and permanent central nervous system damage or death in the mother and, more commonly, in the fetus or neonate
There is no information regarding presence of epinephrine in human milk or effects on the breastfed infant or on milk production
