What is Libtayo?
Libtayo (cemiplimab-rwlc) is a medicine used to treat skin cancer by working with your immune system.
Libtayo 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 anytime during treatment or even after your treatment has ended.
Libtayo strengthens your immune system to help your body fight against cancer cells. This may cause the immune system to attack normal healthy tissues or organs. When this happens, you may develop serious or life-threatening medical problems.
Call your doctor at once if you have new or worsening symptoms such as: chest pain, cough, breathing problems, swelling, nausea, vomiting, changes in appetite or weight, stomach pain, easy bruising or bleeding, mood or behavior changes, severe weakness, vision problems, hair loss, increased or decreased urination, blood in your urine, numbness and tingling, dark urine, or yellowing of the skin or eyes.
