WHY is this medicine prescribed?
Trametinib is used to treat a certain type of melanoma (a type of skin cancer) that cannot be treated with surgery or that has spread to other parts of the body. Trametinib 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.
HOW should this medicine be used?
Trametinib comes as a tablet to take by mouth. It is usually taken once a day on an empty stomach, at least 1 hour before or 2 hours after a meal. Take trametinib at around the same time 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 trametinib 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 trametinib without talking to your doctor.
Your doctor may adjust your dose of trametinib depending on your response to treatment and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment.
