It is therefore very important to look out for symptoms or problems that might indicate a serious adverse reaction. In the Service section, we have provided you with a patient diary, which you can use to record your health condition while undergoing treatment with KEYTRUDA® and which will help you to recognise the occurrence of possible side effects at an early stage.
Your doctor will be able to give you other medicines to alleviate your symptoms and prevent more serious complications. Many of the side effects can be managed without the need to permanently discontinue the KEYTRUDA® treatment.
