      • It takes about an hour to infuse ganciclovir (Cytovene IV) into your veins. Your provider won't be able to give you this medication any faster than an hour because it could cause serious side effects.

        • You and your partner are recommended to use birth control while you're taking this medication because ganciclovir (Cytovene IV) might cause harm to the unborn baby during pregnancy. Females should use an effective birth control method while taking ganciclovir (Cytovene IV) and for at least 30 days after stopping the medication.

              faqs

              Frequently asked questions about Ganciclovir (Cytovene IV)

              How serious is cytomegalovirus (CMV)?
              CMV is actually a very common virus; over half of adults have had CMV by age 40. Once the virus is in your body, it stays there for life. If you have a healthy immune system, you most likely won't experience any symptoms. This is because usually our immune system prevents the virus from causing serious illness. But if you have a suppressed (weakened) immune systems, the CMV can cause serious symptoms that affect the eyes, lungs, liver, stomach, and gut. Ganciclovir (Cytovene IV) is useful in that it helps prevent and treat CMV in individuals with weakened immune systems.
              What's the difference between ganciclovir and valganciclovir?
              Both ganciclovir (Cytovene IV) and valganciclovir (Valcyte) are the same active medication and are used prevent and treat CMV. The major difference is that ganciclovir (Cytovene IV) is an injectable medication while valganciclovir is taken orally (by mouth). Valganciclovir is the prodrug of ganciclovir, meaning that your body breaks down valganciclovir into ganciclovir after you take it by mouth. For this reason, the two medications cause similar side effects.
              Do I have to get ganciclovir (Cytovene IV) in my eye if I have CMV retinitis?
              Ganciclovir (Cytovene IV) is FDA-approved for injection into the veins (IV) for the treatment of CMV retinitis. But according to the American Academy of Ophthalmology, some healthcare providers might choose to use this medication off-label and inject it directly into the eye (in the fluid behind the lens in the eye). The dose for this use is much lower, and it's usually still in combination with treatment that targets the enitre body (systemic therapy). There are no studies confirming the benefit of adding on ganciclovir injections into the eye for CMV retinitis treatment, but the thought is that it might treat the CMV retinitis faster than treatment with IV injections alone.
              How long do I need to take ganciclovir (Cytovene IV)?
              The length of time you need to take ganciclovir (Cytovene IV) depends on what condition you're being treated for. If you're using this medication to prevent CMV disease after an organ transplant, you'll typically be treated for about 3 to 4 months after your transplant (though this might be different depending on what type of transplant you've received). If you're being treated for CMV eye infection, you might need to receive ganciclovir (Cytovene IV) maintenance treatment for at least 3 to 6 months depending on factors such as your eye lesions and your white blood cell count. Talk with your provider about how longer your ganciclovir (Cytovene IV) treatment should take.
              Can I receive ganciclovir (Cytovene IV) if I haven't had a transplant?
              Ganciclovir (Cytovene IV) is only FDA-approved to treat CMV eye infection and to prevent CMV disease after a transplant. But the HIV guidelines from the National Institute of Health do recommend ganciclovir (Cytovene IV) (off-label) for the treatment of CMV that has spread to organs of the body like the gut (colon), throat, lungs, and the nervous system. Talk with your provider if you've questions about whether this medication is a good option for you.

              Ganciclovir (Cytovene IV) 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.

              • Risk factors: Using medications that cause low blood cell counts | Kidney problems | History of low blood count from ganciclovir or other similar medications

                Ganciclovir (Cytovene IV) can lower your blood cell counts and damage your bone marrow. This can make it harder for your body to fight new infections and raises your risk of bleeds. But it's also possible that you won't experience any symptoms, so your provider will order blood tests regularly to check your cell counts. Ganciclovir (Cytovene IV) might not be recommended for you if your blood cell counts are already low. Your provider might change your dose or stop the medication if your blood counts become too low. Low blood counts can happen any time during ganciclovir (Cytovene IV) treatment, but can occur as early as after 1 to 2 weeks of starting this medication. Your blood counts will typically start to improve 3 to 7 days after stopping the medication. Let your providers know right away if you experience symptoms of low blood cell counts, such as:

                risk-warning

                Fertility problems

                Ganciclovir (Cytovene IV) at prescribed doses can cause fertility problems in both males and females. Sometimes, this can be permanent. If you're thinking about having a child in the future, talk to your healthcare provider about family planning before you begin treatment.

                risk-warning

                Harm to unborn babies

                Based on animal studies, ganciclovir (Cytovene IV) might cause harm to an unborn baby if taken during pregnancy. This risk is also true for males taking the medication who have female partners who may become pregnant. For this reason, females should use an effective birth control method while taking ganciclovir (Cytovene IV) and for at least 30 days after they stop the medication. Males should use condoms while taking ganciclovir (Cytovene IV) and for at least 90 days after they stop the medication.

                risk-warning

                Cancer risk

                Based on animal studies ganciclovir (Cytovene IV) has the potential to cause cancer in humans. Talk to your provider if you have concerns.

                risk-warning

                Kidney problems

                • Risk factors: Dehydration | Older adults | Using other medications that harm the kidneys

                  If you have kidney problems, it's possible for ganciclovir (Cytovene IV) to build up in your body and cause more side effects. In addition, ganciclovir (Cytovene IV) can cause serious harm to the kidneys, especially in older adults. The risk is also higher if you don't drink enough fluids or take other medications that can harm the kidneys. Stay hydrated while taking ganciclovir (Cytovene IV) and talk to your provider before taking any medications, including over-the-counter (OTC) pain and cold medications. Your provider will order regular lab tests to monitor your kidneys. If your labs show changes in how well your kidneys work, your provider might change your dose.
