For further information for physicians or healthcare professionals on the preparation of the dilution see section "The following information is intended for medical and healthcare professionals only" at the end of this leaflet. How Iloprost is given The solution is infused intravenously with a venous catheter directly into one of the veins in your arm or into a central intravenous catheter inserted into a vein near your neck. Iloprost is administered as infusion over 6 hours daily. The dose is adjusted according to individual tolerability within the range of 0.5 to 2.0 nanograms iloprost/kg body weight/min. iloprost/kg/min. Your blood pressure and heart rate will be measured at the start of the infusion and after every dose increase. How much Iloprost is given During the first 2 to 3 days, the individually tolerated dose is established. For this purpose, your doctor will start the treatment at a low dose. Treatment should be started at an infusion rate of 0.5 nanograms/kg/min for 30 minutes. The dose should then be increased at intervals of 30 minutes in steps of 0.5 nanograms/kg/min up to a maximum of 2.0 nanograms/kg/ min. The exact infusion speed should be calculated on the basis of body weight to reach an infusion within the range of 0.5 to 2.0 nanograms/kg/min. If adverse effects occur, such as headache and nausea or an undesirable drop in blood pressure, tell your doctor immediately. The infusion rate should be reduced until the tolerable dose is found. If the adverse effects are severe, the infusion should be interrupted. For the remaining duration, the treatment should be continued with the dose found to be tolerated in the first 2 to 3 days.

The following sections provide more information to your doctor when using and infusion pump or a syringe driver for the administration of Iloprost. Infusion rates (ml/hour) for different doses using an infusion pump In general, the ready-to-use infusion solution is infused intravenously by means of an infusion pump (e.g. Infusomat®). In case of an Iloprost 100 micrograms/ml concentration of 0.2 micrograms/ml, the required infusion rate should be determined according to the below described scheme to reach a dose within the range of 0.5 to 2.0 nanograms/kg/min. The following table (Table 1) can be used to calculate the infusion rate corresponding to the individual weight of the patient and the dose to be infused. Match the patient's actual weight on the table, then set the infusion rate based on the desired dose in nanograms/kg/min.

Table 1: Infusion rates [ml/h] for different doses when using an infusion pump. Body weight [kg] 40 50 60 70 80 90 100 110

Infusion rates (ml/hour) for different doses using an syringe driver A syringe driver with a 50 ml injection syringe (e.g.Perfusor®) may also be used to infuse Iloprost 100 micrograms/ml. In case of an Iloprost 100 micrograms/ml concentration of 0.2 micrograms/ml, the required infusion rate must be determined according to the below described scheme, to reach a dose within the range of 0.5 to 2.0 nanograms/kg/min.

with an infusion pump, it will be diluted before infusion to a final concentration of 0.2 micrograms/ml. If Iloprost is administered with an injector, it will be diluted before infusion to a final concentration of 2 micrograms/ml. Patients with kidney or liver problems If you have kidney problems requiring dialysis or liver cirrhosis, iloprost elimination is reduced and a dose reduction (e.g. half the recommended dose) is necessary. Tell your doctor if you have problems with your liver or kidneys.

How to take it

The duration of the treatment is up to 4 weeks. The safety and efficacy of Iloprost has not been studied for treatment for longer than 4 weeks or after repetitive cycles. Continuous infusion over several days is not recommended, because it can lead to reduced effect on platelets and increased platelet aggregation (platelet hyperaggregability) at the end of treatment. No clinical complications associated with these phenomena have been reported. If you feel that the effect of Iloprost is too strong or too weak, tell your doctor. If you are given more Iloprost than you should Drop in blood pressure (hypotensive reaction) can be expected, as well as headache, redness of the face (flushing), nausea, vomiting and diarrhoea. An increase in blood pressure, reduced or increased heart rate and limb or back pain may also occur. No specific antidote is known. In case of overdose, your doctor is advised to discontinue infusion of iloprost, to monitor you and treat your symptoms. If you stop the treatment with Iloprost If the infusion therapy with Iloprost is discontinued, your doctor will take care to restore the changes that might have been made to other medicines you take, due to Iloprost administration (e.g. dose reductions). If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse. 4.
