Patient Education

Trametinib


Trametinib is used alone or in combination with dabrafenib (Tafinlar) to treat a 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 used in combination with dabrafenib to treat and prevent the return of a certain type of melanoma after surgery to remove it and any affected lymph nodes. Trametinib is also used in combination with dabrafenib to treat a certain type of non-small-cell lung cancer (NSCLC) that has spread to nearby tissues or to other parts of the body. It is used in combination with dabrafenib to treat a certain type of thyroid cancer that has spread to nearby tissues or to other parts of the body, which cannot be treated with other therapies. 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. =

Cancer Chemotherapy


Normally, your cells grow and die in a controlled way. Cancer cells keep growing without control. Chemotherapy is drug therapy for cancer. It works by killing the cancer cells, stopping them from spreading, or slowing their growth. However, it can also harm healthy cells, which causes side effects.

You may have a lot of side effects, some, or none at all. It depends on the type and amount of chemotherapy you get and how your body reacts. Some common side effects are fatigue, nausea, vomiting, pain, and hair loss. There are ways to prevent or control some side effects. Talk with your health care provider about how to manage them. Healthy cells usually recover after chemotherapy is over, so most side effects gradually go away.

Your treatment plan will depend on the cancer type, the chemotherapy drugs used, the treatment goal, and how your body responds. Chemotherapy may be given alone or with other treatments. You may get treatment every day, every week, or every month. You may have breaks between treatments so that your body has a chance to build new healthy cells. You might take the drugs by mouth, in a shot, as a cream, or intravenously (by IV).
