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?
Monitoring
Before you take MEKINIST, your doctor will take tumour tissue samples to check whether
MEKINIST is suitable for you.
Your doctor should check your heart before you start taking MEKINIST and during treatment.
Your doctor may arrange for you to have an eye examination before you take MEKINIST
and while you are taking it.
