Sorafenib Tosylate Information
Sorafenib is used to treat advanced renal cell carcinoma (RCC; a type of cancer that begins in the kidneys). Sorafenib is also used to treat hepatocellular carcinoma (a type of liver cancer) that cannot be treated with surgery and a certain type of thyroid cancer that has spread to other parts of the body and cannot be treated with radioactive iodine. Sorafenib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply.This helps stop the spread of cancer cells.
Sorafenib comes as a tablet to take by mouth. It is usually taken twice a day. Sorafenib is taken without food, 1 hour before or 2 hours after a meal. Take sorafenib at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sorafenib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole with water. Do not split, chew, or crush them.
Your doctor may decrease your dose of sorafenib during your treatment, or may tell you to stop taking sorafenib for a period of time if you experience side effects. Be sure to tell your doctor how you are feeling during your treatment with sorafenib.
Continue to take sorafenib even if you feel well. Do not stop taking sorafenib without talking to your doctor.
Sorafenib is not available in pharmacies. You can only get sorafenib through the mail from a specialty pharmacy. Ask your doctor if you have any questions about receiving your medication.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to sorafenib. Your doctor will also check your blood pressure every week during the first six weeks of your treatment and then from time to time as needed.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
