1. What is PREVYMIS and what is it used for

PREVYMIS is a prescription antiviral medicine that contains the active substance letermovir.

PREVYMIS is a medicine for:

• adults and children weighing at least 5 kg who have recently undergone a stem cell transplant (bone marrow transplant).
• adults and children weighing at least 40 kg who have recently undergone a kidney transplant.

The medicine helps to prevent you from getting the disease caused by CMV (cytomegalovirus).

CMV is a virus. For most people, CMV does not cause any harm. However, if your immune system is weakened after receiving a stem cell or kidney transplant, you may be at high risk of getting sick from CMV.

2. What you need to know before you are given PREVYMIS

You should not be given PREVYMIS:

• if you are taking any of the following medicines:
• • pimozide - used for Tourette's syndrome
  • ergot alkaloids (such as ergotamine and dihydroergotamine) - used for migraine headaches.
• if you are taking the following herbal medicine:
• • St. John's Wort (Hypericum perforatum)

You should not be given PREVYMIS if any of the above situations apply to you. If you are unsure, talk to your doctor, pharmacist, or nurse before you are given PREVYMIS.

If you are taking PREVYMIS with cyclosporine, do not take the following medicines:

Warnings and precautions

If you are also taking a medicine to treat high cholesterol (see list of medicines in the section "Other medicines and PREVYMIS"), you must tell your doctor immediately if you have unexplained muscle pain or weakness, especially if you are feeling unwell or have a fever. It may then be necessary to change your medicine or dose. For more information, see the leaflet for your other medicine.

• cyclosporine, tacrolimus, sirolimus
• voriconazole

Children and adolescents

PREVYMIS should not be used in children who weigh less than 5 kg who have received a stem cell transplant (bone marrow transplant) or in children who weigh less than 40 kg who have received a kidney transplant. This is because PREVYMIS has not been studied in these groups.

Other medicines and PREVYMIS
