Blood and lymphatic system disorders Uncommon: increase in eosinophilic cells (eosinophilia), reduction in white blood cells (leucopenia) which makes infections more likely Rare: reduction in red blood cells (anaemia), increase in white blood cells (leucocytosis), alteration of the prothrombin (coagulation factor) values, reduction in blood platelets (thrombocytopenia) with bruises and tendency to bleed, increase in blood platelets (thrombocytosis) Very rare: reduction in red blood cells due to extensive destruction of these cells (haemolytic anaemia), severe reduction in blood cells (pancytopenia), severe reduction in white blood cells characterised by sudden high fever, very sore throat and mouth ulcers (agranulocytosis)
