Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about XERMELO. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking XERMELO against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.

What XERMELO is used for

This medicine contains the active substance telotristat ethyl.
XERMELO is used in adults for the treatment of a condition called 'carcinoid syndrome'. This is when a tumour, called a 'neuroendocrine tumour', releases a hormone called serotonin into your bloodstream.
When the tumour releases too much serotonin into your bloodstream you can get symptoms such as:
diarrhoea and stomach (abdominal) pain
flushing of your skin, particularly the face
low blood pressure
weight loss.
The symptoms are not the same for everyone.
XERMELO works by reducing the amount of serotonin made by the tumour. It will reduce your diarrhoea.
Your doctor will prescribe XERMELO:
when your tumour has spread to different parts of your body
and if your diarrhoea is not well controlled with injections of other medicines called 'somatostatin analogues' (lanreotide or octreotide). You should keep having injections of these other medicines when taking XERMELO.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
