Aminosyn II 3.5 Professional Information


Aminosyn II 3.5% in 5% Dextrose Injection (without electrolyte additives) is hypertonic; it can be infused through a peripheral vein paying great care to the possible occurrence of local reactions. Local reactions consisting of a warm sensation, erythema, phlebitis and thrombosis at the infusion site have occurred with peripheral intravenous infusion of amino acids; in such cases the infusion site should be changed promptly to another vein. Use of large peripheral veins, inline filters, and slower rates of infusion may reduce the incidence of local venous irritation. Electrolyte additives should be spread throughout the day. Irritating additive medications may need to be injected at another venous site.

Generalized flushing, fever and nausea have been reported during peripheral infusions of amino acid solutions.
