Why is this medication prescribed?
Binimetinib is used along with encorafenib (Braftovi) 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. Binimetinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
How should this medicine be used?
Binimetinib comes as a tablet to take by mouth. It is usually taken with or without food twice daily, approximately 12 hours apart. Take binimetinib at around the same time(s) 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 binimetinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you vomit after taking the medication, do not take another dose. Continue your regular dosing schedule.
Your doctor may decrease or temporarily or permanently stop your treatment depending on if you experience any side effects. Be sure to tell your doctor how you are feeling during your treatment with binimetinib.

What should I know about storage and disposal of this 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).
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 emergency/overdose
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.
What other information should I know?
Keep all appointments with your doctor, eye doctor, and the laboratory. Your doctor will order certain lab tests, including eye exams, to check your body’s response to binimetinib.
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.
