 Consumer Medicine Information (CMI)

This leaflet provides important information about using XERMELO. 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 XERMELO.

7. Product details

1. Why am I using XERMELO?

XERMELO contains the active ingredient telotristat ethyl. XERMELO is tryptophan hydroxylase inhibitor that works by reducing the amount of serotonin made by the tumour.

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
  • rash
  • weight loss

The symptoms are not the same for everyone.

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.

2. What should I know before I use XERMELO?

Warnings

Do not use XERMELO if:

  • you are allergic to telotristat ethyl, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • have allergies to any other medicines, foods, preservatives or dyes.
  • have any other medical conditions, such as:
    - liver problems. This is because this medicine is not recommended for use in patients with severe liver problems. Your doctor may decide to decrease your daily dose of XERMELO in cases where your liver problems are considered mild or moderate. Your doctor will also monitor your liver.
    - end-stage kidney disease or are on dialysis. This is because this medicine has not been tested in patients with end-stage kidney disease requiring dialysis.
  • are pregnant or plan to become pregnant.
  • are breast-feeding.
  • take any medicines for any other condition.

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

Check with your doctor if you are pregnant or intend to become pregnant. It is not known how XERMELO may affect the baby.

Women should use effective methods of contraception while taking this medicine.

Talk to your doctor if you are breastfeeding or intend to breastfeed. It is unknown if the active ingredient in XERMELO passes into breast milk and there is a possibility that your baby may be affected.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and XERMELO may interfere with each other. Tell your doctor or pharmacist if you are taking, have taken or are planning to take any of the following:

  • medicines for diarrhoea. XERMELO and these medicines reduce the number of your bowel movements and taken together, they can cause severe constipation. Your doctor may need to change the dose of your medicines.
  • medicines used to treat epilepsy, such as valproic acid, carbamazepine and topiramate.
  • medicines used to treat your neuroendocrine tumour, such as sunitinib or everolimus.
  • medicines to treat depression, such as sertraline.
  • medicine to treat smoking cessation, such as bupropion.
  • medicines used to avoid transplant rejection, such as ciclosporin.
  • medicines used to lower cholesterol levels, such as simvastatin and atorvastatin.
  • oral contraceptives, such as ethinyloestradiol.
  • medicines used to treat high blood pressure, such as amlodipine, nifedipine, felodipine, verapamil and diltiazem.
  • medicines used to treat some types of cancers, such as irinotecan, capecitabine and flutamide.
  • medicines used to reduce the chance of a blood clot forming, such as prasugrel.
  • octreotide. If you need treatment with octreotide subcutaneous injection, you should have your injection at least 30 minutes after taking XERMELO.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect XERMELO.

These medicines may be affected by XERMELO or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

4. How do I use XERMELO?
