Dabrafenib may be used alone or in combination with another medication (trametinib) to treat a type of skin cancer (melanoma) that has spread or cannot be removed by surgery and has a certain type of abnormal "BRAF" gene. Dabrafenib belongs to a class of drugs known as kinase inhibitors. It works by slowing the growth of skin cancer cells.

How to use Tafinlar oral

Read the Medication Guide provided by your pharmacist before you start taking dabrafenib and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually twice daily about 12 hours apart. Take this medication on an empty stomach, at least 1 hour before or 2 hours after meals. Swallow the capsules whole. Do not open, crush, chew, or break the capsules.

The dosage is based on your medical condition and response to treatment.

Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of serious side effects will increase. Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.
