Consumer Medicine Information (CMI)
This leaflet provides important information about taking KOSELUGO. 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 KOSELUGO.
Where to find information in this leaflet:

Why am I taking KOSELUGO?

KOSELUGO contains the active ingredient selumetinib. Selumetinib is a type of medicine called a ‘MEK inhibitor’, it works by blocking certain proteins which are known to be involved in the growth of tumour cells. KOSELUGO may reduce the size of tumours that grow along nerves called Plexiform Neurofibromas (PNs). The tumours are caused by a genetic condition called Neurofibromatosis Type 1 (NF1).
KOSELUGO is used to treat paediatric patients aged 2 years and above with NF1, who have symptomatic plexiform neurofibromas that cannot be completely removed by surgery.

What should I know before I take KOSELUGO?

supplements that include vitamin E (including multivitamins that contain vitamin E)
KOSELUGO may increase the level of an enzyme in your blood called creatine phosphokinase (CPK) and may be a sign of muscle damage. Your healthcare provider should do a blood test to check your blood levels of CPK before you start taking KOSELUGO and during treatment.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Talk to your doctor before taking KOSELUGO if you are pregnant, think you may be pregnant or are planning to have a baby. This is because KOSELUGO may harm an unborn child.

Female patients: If you are able to become pregnant you should use effective contraception while you are taking KOSELUGO and for at least 1 week after the last dose. It is not known whether KOSELUGO may interfere with how well hormonal contraceptives work.
