Information for healthcare professionals: The treatment of the developed condition requires the use of diuretics for edema, beta-blockers or other inhibitors of the sympathetic nervous system for tachycardia, and sodium chloride in isotonic intravenous solution for hypotension. Sympathomimetics, such as adrenaline and noradrenaline, should be avoided due to the cardiac overstimulation they produce.
