What side effects could I experience?
Imatinib will cause the level of your red blood cells, white blood cells and platelets to drop.
Red blood cells carry oxygen and nutrients around your body. A fall in the level of red blood cells may make you feel tired and worn out.
White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Alert your doctor if you have a fever, or a cough or flu that does not go away.
Platelets help your blood to clot when there is a cut in the skin. When the level of your platelets drops, you may be at risk of bleeding more than usual. Do not participate in activities in which you may fall or get injured, such as contact sports. Alert your doctor if you get any unusual bruising (large bruises or several bruises) or bleeding that takes a long time to stop (for example, too much bleeding when you floss or brush your teeth).
Imatinib may cause mild swelling in your legs and around your eyes. This is caused by accumulation of fluid around these areas. However, if you experience severe swelling, breathlessness, sudden or unexplained weight gain, call your doctor quickly.
Diarrhoea, nausea, vomiting, rashes, headaches, tiredness and muscle cramps are other common side effects of Imatinib. Usually, these are not severe and can be managed with simple medicines and rest. However, if any of these side effects become severe or do not go away, alert your doctor quickly.
