Titration of dose: Once an infusion of noradrenaline has been established the dose should be titrated in steps of 0.05 -0.1 µg/kg/min of noradrenaline base according to the pressor effect observed. Charted on fluid chart giving: rate in ml/hour. When diluted as recommended, each ml contains 80 micrograms noradrenaline tartrate equivalent to 40 micrograms noradrenaline base. These may be accompanied by violent headache, photophobia, retrosternal pain, pallor, intense sweating and vomiting. Continue, 2. Noradrenaline should be continued for as long as vasoactive drug support is indicated. In both cases the final concentration of the infusion solution is 40 mg/litre noradrenaline base (which is equivalent to 80 mg/litre noradrenaline tartrate). 40 mg/litre (40 µg /ml) noradrenaline base. This medicinal product may be diluted with sodium-containing solutions (see sections 4.2 and 6.6) and this should be considered in relation to the total sodium from all sources that will be administered to the patient.

If plasma volumes are not corrected, hypotension may recur when the infusion is discontinued, or blood pressure may be maintained at the risk of severe peripheral and visceral vasoconstriction (e.g., decreased renal perfusion) with diminution in blood flow and tissue perfusion with subsequent tissue hypoxia and lactic acidosis and possible ischaemic injury. It allows continued monitoring of the benefit/risk balance of the medicinal product. When suggestions are available use up and down arrows to review and ENTER to select. Healthcare professionals are asked to report any suspected adverse reactions via the UK Yellow Card Scheme.
