1. Why am I using NEXAVAR?

NEXAVAR contains the active ingredient sorafenib tosilate. NEXAVAR is a multi-kinase inhibitor. It works by slowing down the rate of growth of cancer cells and cutting off the blood supply that keeps cancer cells growing.

NEXAVAR is used to treat advanced liver cancer (hepatocellular carcinoma), advanced kidney cancer (renal cell carcinoma), or thyroid cancer (differentiated thyroid carcinoma).

2. What should I know before I use NEXAVAR?


Do not use NEXAVAR if:

  • you are allergic to sorafenib tosilate, or any of the ingredients listed at the end of this leaflet.
  • Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • Experience skin problems. NEXAVAR can cause rashes and skin reactions, especially on hands and feet. These can usually be treated by your doctor. If not, your Nexavar treatment may be interrupted or stopped altogether.
  • Have high blood pressure. NEXAVAR can raise blood pressure, and your doctor will usually monitor your blood pressure and may give you medicine to treat your high blood pressure.
  • Have any bleeding problems, or are taking warfarin. Treatment with NEXAVAR may lead to a higher risk of bleeding. If you are taking warfarin, which thins the blood to prevent blood clots, there may be a greater risk of bleeding.
  • Have a history of aneurysm. Your doctor may discuss with you the risk of taking NEXAVAR
  • Are going to have surgery, or you have had an operation recently. Nexavar might affect the way your wounds heal. You will usually be taken off NEXAVAR if you are having an operation. Your doctor will decide when to start with NEXAVAR again.
  • Suffer from chest pain (angina) or have suffered a heart attack (myocardial infarction) recently. Your doctor may decide to interrupt treatment or stop it altogether.
  • Have an abnormality of your heart trace known as prolonged QT interval. NEXAVAR may affect your heart rhythm.
  • Have severe hepatic impairment (liver failure). You may experience more severe side effects when taking this medicine.
  • Are taking irinotecan (Camptosar), capecitabine (Xeloda) or docetaxel (Taxotere), which are other drugs used in the treatment of cancer, or other related drugs. You may experience more side effects when taking combination therapy.
  • Have thyroid cancer, your doctor will monitor blood calcium and thyroid hormone levels.
  • take any medicines for any other condition

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Women should avoid becoming pregnant while undergoing treatment with NEXAVAR.
