Opdualag (Nivolumab + relatlimab)

Why is Opdualag prescribed?

Opdualag (a combination of nivolumab and relatlimab) is used to treat certain types of melanoma (a type of skin cancer) that has spread to other parts of the body or cannot be removed by surgery. It is approved for use in adults and children 12 years of age or older who weigh at least 40 kg.

Opdualag is in a class of medications called immunotherapy. They work by activating your immune system to find and kill cancer cells.

How should Opdualag be used?

Patient getting Opdualag cancer treatment

Opdualag is given as an infusion into a vein over 30 minutes by a doctor or nurse in a hospital or medical facility. It is usually given every 4 weeks for as long as your doctor recommends that you receive treatment.

Opdualag can cause serious or life-threatening reactions during an infusion. A doctor or nurse will watch you closely while you are receiving the infusion and shortly after the infusion to be sure you are not having a serious reaction to the medication. Tell your doctor or nurse immediately if you experience any of the following symptoms that may occur during the infusion: chills or shaking, itching, rash, flushing, difficulty breathing, dizziness, fever, and feeling faint.

Your doctor may slow down your infusion, delay it, or stop your treatment. They may treat you with additional medications to decrease the chance of it happening again.

What special precautions should I follow?
