Let's take a minute to talk about your medication. 

This is Opdivo. It helps treat certain types of cancer. Opdivo is not called chemotherapy. Instead, it works with your immune system to target cancer cells. 

Opdivo is given as an infusion into a vein. This is called an 'IV' infusion. Your doctor will determine how often you should receive this medicine, and for how long. 

Opdivo can cause a reaction to happen during an infusion. Your doctor or nurse will watch you closely during each dose and tell you which symptoms to report. They will be prepared to treat any concerns. 

Common side effects include feeling tired, or having a headache, nausea, a decreased appetite, and either diarrhea or constipation. You could have pain in your muscles, bones and joints. These effects are normal if they are mild and should go away. You should wait until you know how this medicine affects you before you do activities that require you to be alert, like driving. Other common side effects include a rash, itching, a cough, or shortness of breath. You should tell your doctor right away if you have these or ANY side effects to make sure they are not a more serious condition. 

As with any medicine, more serious side effects could occur. With Opdivo, some effects could be life-threatening. It is very important to read the Medication Guide to know which symptoms to watch for and when to report them. To help keep this medicine safe for you, your doctor will follow your condition closely and may order blood tests.

Opdivo is not safe for unborn babies. Women must talk to their doctors about which birth control to use, and for how long. Women should not breastfeed.

For best results with Opdivo, work closely with your oncologist to know exactly how to report side effects.
