Patients on low sodium diets can be informed that this medicinal product is essentially 'sodium-free'. Noradrenaline may impair placental perfusion and induce fetal bradycardia. For compatibility with infusion bags see section 6.6. It may also exert a contractile effect on the pregnant uterus and lead to fetal asphyxia in late pregnancy. The effect on blood pressure disappears 1-2 minutes after stopping the infusion. No information is available on the use of noradrenaline in lactation. Noradrenaline should be used only in conjunction with appropriate blood volume replacement. 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. Chemical and physical in-use stability has been demonstrated for 24 hours at 25°C when diluted to 4 mg/litre and 40 mg/litre noradrenaline base in sodium chloride 9 mg/ml (0.9%) solution or glucose 5% solution.

Any unused medicinal product or waste material should be disposed of in accordance with local requirements. Either add 2 ml concentrate to 48 ml glucose 5% solution (or sodium chloride 9 mg/ml (0.9%) with glucose 5% solution) for administration by syringe pump, or add 20 ml of concentrate to 480 ml glucose 5 % solution (or sodium chloride 9 mg/ml (0.9%) with glucose 5% solution) for administration by drip counter. 40 mg/litre (40 µg /ml) noradrenaline base. There is no experience in treatment of renally or hepatically impaired patients. Healthcare professionals are asked to report any suspected adverse reactions via the UK Yellow Card Scheme. 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). If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8°C. The increase in blood pressure may cause a reflex decrease in heart rate. Noradrenaline may impair placental perfusion and induce fetal bradycardia. Dilutions other than 40 mg/litre noradrenaline base may also be used (see section 4.2). Up to 16% of an intravenous dose is excreted unchanged in the urine with methylated and deaminated metabolites in free and conjugated forms. Peripheral resistance increases and diastolic and systolic pressures are raised. 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.

All feedback and … Ampoules containing 2 ml and 4 ml of concentrate. Some clinicians may wish to start at a lower initial infusion rate of 5 ml/hour (0.08 ml/min), equivalent to 0.2 mg/hour noradrenaline base (0.4 mg/hour noradrenaline tartrate). The infusion should be at a controlled rate using either a syringe pump or an infusion pump or a drip counter. The noradrenaline infusion should be gradually decreased since abrupt withdrawal can result in acute hypotension. 1 ampoule of 2 ml contains 4 mg noradrenaline tartrate equivalent to 2 mg noradrenaline base. In the event of overdosage, treatment should be withdrawn and appropriate corrective treatment initiated. Local vasoconstriction may cause haemostasis and/or necrosis. Particular caution should be observed in patients with coronary, mesenteric or peripheral vascular thrombosis because noradrenaline may increase the ischemia and extend the area of infarction. Except in the heart, its action is predominantly on the alpha receptors. Noradrenaline should be continued for as long as vasoactive drug support is indicated. Extravasation of the solution may cause local tissue necrosis. The infusion site should be checked frequently. This medicinal product contains less than 1 mmol sodium (23 mg) per ampoule.
