During treatment with KEYTRUDA and LENVIMA, side effects for each medication can occur. It’s important to understand these side effects so you can start the conversation with your health care provider about how you are feeling. Talk to your health care provider immediately if you experience something that feels new or different.
KEYTRUDA and LENVIMA are prescription medicines used together to treat a kind of uterine cancer called advanced endometrial carcinoma:
This use is approved based on how many patients responded to treatment and how long they responded. Studies are ongoing to provide additional information about clinical benefit.
It is not known if LENVIMA is safe and effective in children.
KEYTRUDA is a medicine that may treat certain cancers by working with your immune system. KEYTRUDA can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. These problems may happen any time during treatment or even after your treatment has ended.
