Like all medicines, Myclausen can have side effects, although not everybody gets them. Some of the more usual problems are diarrhoea, fewer white cells and/or red cells in your blood, infection and vomiting. Your doctor will do regular blood tests to monitor any changes in the number of your blood cells or changes in the levels of any of the substances carried in your blood, e.g. sugar, fat, cholesterol. Children may be more likely than adults to have side effects such as diarrhoea, infections, fewer white cells and fewer red cells in the blood.
Myclausen reduces your body?s own defence mechanisms to stop you rejecting your transplanted kidney, heart or liver. Consequently your body will not be as good as normal at fighting infections. So if you are taking Myclausen you may therefore catch more infections than usual, such as infections of the brain, skin, mouth, stomach and intestines, lungs and urinary tract. As can happen in patients taking this type of medicine, a very small number of Myclausen patients have developed cancer of the lymphoid tissues and skin.
