Mekinist treats a certain type of skin and lung cancer. Take Mekinist 1 hour before or 2 hours after a meal.
Mekinist is a prescription medication 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.
This medication is also approved to treat those with a certain type of lung cancer when given with another medication called dabrafenib.
Mekinist belongs to a group of drugs called kinase inhibitors. These work by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.
Mekinist 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 Mekinist at around the same time every day.
Common side effects include rash, diarrhea, and swelling of the face, arms, or legs.
