Livtencity (maribavir) is a newer antiviral medication that treats cytomegalovirus (CMV) in people who've received a transplant. It's not a first-choice medication, but only used if the CMV infection didn't respond to traditional treatment, such as ganciclovir, valganciclovir, and cidofovir.
Livtencity (maribavir) is an antiviral drug against CMV. It works by blocking the activity of a special viral enzyme (protein) called pUL97. This process helps stop the growth and survival of the CMV virus.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

Livtencity (maribavir) treats CMV. This is a common virus that can spread when you come into contact with fluids, like saliva or urine, from an infected person. People with a healthy immune system can usually fight off CMV. Typically, the virus just stays in their body without causing many problems. However, people with a weakened immune system, such as those who've received an organ transplant and need to take transplant medications to prevent rejection, can get severely sick from a CMV infection. Livtencity (maribavir) helps treat CMV that doesn't respond to typical treatment. Not taking the full course your provider has prescribed to you can make your CMV infection much harder to treat.
No. Taking Livtencity (maribavir) with antiviral medications, like valganciclovir (Valcyte) or ganciclovir (Cytovene IV), can cancel out antiviral activity altogether. This means these medications won't work any longer for CMV. For this reason, your provider will have you stop taking valganciclovir (Valcyte) or ganciclovir (Cytovene IV) when you start Livtencity (maribavir).
Both Livtencity (maribavir) and Prevymis (letermovir) are antiviral medications that target the CMV virus, but they are very different. Letermovir is meant to prevent CMV, while Livtencity (maribavir) treats CMV. Furthermore, Prevymis (letermovir) is only approved for adults who've received a stem cell transplant, while Livtencity (maribavir) can also be used in people who've received a solid organ transplant (e.g., kidney, pancreas, liver). Your transplant provider will make sure that you're taking the appropriate antiviral medication.
Follow your provider's instructions for how long to take Livtencity (maribavir). Typically, you'll need to take this medication twice daily. Sometimes, people experience resistance, which is when the CMV virus changes in a way that stops antiviral medications from working well against it. This can make the virus harder to treat. Resistance can happen during treatment with Livtencity (maribavir) or even up to 2 months after stopping it. For this reason, take Livtencity (maribavir) exactly as prescribed and make sure to keep all of your lab appointments so your provider can monitor your CMV virus levels.
You can take Livtencity (maribavir) with or without food. A common side effect of this medication is nausea, so it might be helpful to have something in your stomach before taking it. However, this isn't necessary for the medication to work well.
Livtencity (maribavir) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
There's a possibility that your CMV infection is resistant (won't respond well) to Livtencity (maribavir). This means that the infection won't go away even after you take Livtencity (maribavir). Sometimes, the infection goes away, but comes back 1 to 2 months later. Please monitor yourself for symptoms of CMV infection while you're taking Livtencity (maribavir) and for 2 months after treatment. Let your provider know if you experience fever, sore throat, or tiredness.
There are many medications that interact with Livtencity (maribavir). Some medications, including Livtencity (maribavir), might need to have the dosages adjusted or you might need to stop taking them altogether. Taking a medication that interacts with Livtencity (maribavir) can cause it to be less effective and cause a CMV infection that's harder to treat. Or, some interactions can give you severe side effects. Make sure to tell your provider about all of the medications you take before starting Livtencity (maribavir). This includes prescriptions, over-the-counter medications, and supplements. Don't start any new medications while taking Livtencity (maribavir) without talking to your provider or pharmacist first.
