Side effects¹

Although not every patient may experience them, treatment with immunotherapy can cause side effects. Immunotherapy can cause your immune system to attack normal organs and tissues in your body and can affect the way they work. These side effects can sometimes become serious or life-threatening, so it is important that you report any symptoms to your oncologist, cancer specialist or cancer nurse as soon as you can. If they are reported early, most of the side effects can be managed and treated effectively, with little interruption to your immunotherapy treatment.

The most common side effects are skin rash, itching, diarrhoea, difficulty breathing, fatigue (extreme tiredness) and weight changes.
