Full Consumer Medicine Information (CMI)

This leaflet provides important information about using MEKINIST. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using MEKINIST.
Where to find information in this leaflet:

1. Why am I using MEKINIST?

MEKINIST contains the active ingredient trametinib.
MEKINIST belongs to a group of medicines called "selective MEK-inhibitors".
MEKINIST is used to:
Treat adult patients with the following types of cancers that have spread to other parts of the body:
- skin cancers called melanoma
- thyroid cancers called anaplastic thyroid cancer (ATC)
- lung cancers called non-small cell lung cancer (NSCLC)
Prevent melanoma from coming back after the melanoma has been removed by surgery in adult patients.
Treat children 1 year and older with a brain tumour (glioma), following other treatments.
These cancers have a change (mutation) in a gene called "BRAF" that may have caused the cancer to grow. MEKINIST targets proteins made from this changed gene and slows down or stops the growth of your cancer.
MEKINIST can be used by itself or in combination with another medicine called TAFINLAR (containing dabrafenib).
If you are taking these two medicines together, read the full TAFINLAR Consumer Medicine Information as well as this one carefully.

2. What should I know before I use MEKINIST?
