Noren Warnings

Emergency treatment of shock is procuring ventilation, raising the blood pressure of the fluid and increasing cardiac output.
The circulation dynamics of the shock varies depending on the state of the disease and cause of shock so, careful about selecting and using the time of blood pressure medication. It is emergency drug for antihypertensive agent, but not a substitute for blood of fluids.
May cause an excessive increase in blood pressure and acute pulmonary edema action, arrhythmia, cardiac arrest may occur, so this may not be excessively administered.
Frequently check the blood pressure and the administration rate when injecting the drug to prevent high blood pressure.
Continuation of this drug without replacement for maintaining of blood pressure may cause remarkable peripheral and internal vasoconstriction, decrease in renal perfusion and urea emission, decrease in blood volume despite normal blood pressure, tissue hypoxia, metabolic acidosis may occur so, using with blood volume replacement should be considered.
Use alpha blocker (phentolamine) if excessive rise in blood pressure.
