- sickle cell anaemia;
- epileptic fits (seizures);

Special warnings
If you have symptoms which include unusual tiredness and a lack of energy this could mean you have pure red cell aplasia (PRCA), which has been reported in patients. PRCA means that the body has stopped or reduced the production of red blood cells which causes severe anaemia. If you experience these symptoms you should contact your doctor who will determine the best course of action to treat your anaemia.
Take special care with other products that stimulate red blood cell production: ARANESP® is one of a group of products that stimulate the production of red blood cells like the human protein erythropoietin does. Your healthcare professional should always record the exact product you are using.
If you are a patient with chronic renal failure, ARANESP® places you at a higher risk for death, problems of the heart (myocardial infarction) or blood vessels, stroke, blood clots (thrombosis) and tumour progression or recurrence. Particularly if you do not respond properly to ARANESP® your doctor will check your dose of ARANESP® repeatedly increasing your dose of ARANESP® if you are not responding to treatment.
Your doctor should try to keep your haemoglobin between 10 and 12 g/dl. Your doctor will check that your haemoglobin does not exceed a certain level, as high haemoglobin concentrations could put you at risk of having a problem of the heart or the blood vessels and could increase risk of myocardial infarction, stroke and death.
If you have symptoms which include severe headache, drowsiness, confusion, problems with your eyesight, nausea, vomiting or fits (seizures), it could mean that you have very high blood pressure. If you experience these symptoms you should contact your doctor.
If you are a ARANESP® acts as a blood cell growth factor and increases the risk of tumour progression or recurrence. You should not use ARANESP® if you are receiving chemotherapy that suppresses you bone marrow’s production of blood cells and platelets. Depending on your individual situation a blood transfusion may be preferable. Please discuss this with your doctor.
Misuse by healthy people can cause life-threatening problems with the heart or blood vessels.
Serious skin reactions including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported in association with epoetin treatment. SJS/TEN can appear initially as reddish target-like spots or circular patches often with central blisters on the trunk. Also, ulcers of mouth, throat, nose, genitals and eyes (red and swollen eyes) can occur. These serious skin rashes are often preceded by fever and/or flu-like symptoms. The rashes may progress to widespread peeling of the skin and life-threatening complications. If you develop a serious rash or another of these skin symptoms, stop taking ARANESP® and contact your doctor or seek medical attention immediately.
If you are undergoing surgery, blot clotting prevention is recommended as ARANESP® places you at higher risk of developing blood clots (deep vein thrombosis).
Other medicines and ARANESP®
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. Ciclosporin and tacrolimus (medicines which suppress the immune system) may be affected by the number of red cells in your blood. It is important to tell your doctor if you are taking either of these medicines.
