Vemurafenib is used to treat certain types of melanoma (a type of skin cancer) that cannot be treated with surgery or that has spread to other parts of the body. It is also used to treat a certain type of Erdheim-Chester disease (ECD; a disease that causes an overproduction of a type of white blood cells). Vemurafenib 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 slow or stop the spread of cancer cells.
Vemurafenib comes as a tablet to take by mouth. It is usually taken with or without food twice a day, in the morning and evening, about 12 hours apart. Take vemurafenib 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 vemurafenib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Do not stop taking vemurafenib without talking to your doctor.
Swallow the tablets whole with a glass of water; do not chew or crush them.
If you vomit after you take vemurafenib, do not immediately take another dose. Continue your regular dosing schedule.
Your doctor may need to temporarily or permanently stop your treatment or decrease your dose of vemurafenib during your treatment.This depends on how well the medication works for you and the side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with vemurafenib.

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).
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
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.
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 vemurafenib. Your doctor will check your skin before starting treatment, every 2 months during your treatment, and for up to 6 months after treatment.
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.
