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 15 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.

  • 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)

Do not take PREVYMIS if any of the above applies to you. If you are unsure, consult your doctor, pharmacist, or nurse before taking PREVYMIS.
