What is Valganciclovir and why is it prescribed? Valganciclovir tablets are used in the treatment of an eye disease called cytomegalovirus (CMV) retinitis, one of the many infections that take hold when the immune system is undermined by AIDS. Valganciclovir is very similar to the CMV medication Cytovene (ganciclovir). To avoid an overdose, it is essential to take only the prescribed number of Valganciclovir tablets each day. These tablets are more potent than Cytovene capsules, and cannot be substituted on a one-for-one basis. How should you take Valganciclovir? Follow your doctors directions for taking Valganciclovir. Valganciclovir is usually taken twice a day for the first three weeks, then once a day. Valganciclovir should be taken with food. Be careful to avoid breaking Valganciclovir tablets. If a tablet does break, keep the pieces out of direct contact with skin, eyes, and mouth. If contact is unavoidable, wash thoroughly with soap and water and rinse the eyes with plain water. If you miss a dose take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Store Valganciclovir at room temperature. Are there any Valganciclovir side effects? Valganciclovir side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Valganciclovir side effects may include abdominal pain, agitation, anemia and other blood abnormalities, bleeding problems, burning or prickling feeling, confusion, convulsions, diarrhea, fever, hallucinations, headache, infection, insomnia, nausea, psychosis, reduced kidney function, retinal detachment, vision problems, and vomiting. What are the possible food and drug interactions when taking Valganciclovir? If Valganciclovir is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. It is especially important to check with your doctor before combining Valganciclovir with Didanosine (Videx), Mycophenolate mofetil (CellCept), Probenecid, or Zidovudine (Retrovir). Are there any special warnings about Valganciclovir? Valganciclovir may cause low blood counts. You will need to have frequent blood tests to monitor for abnormalities. Valganciclovir can also affect the kidneys, so your doctor will check them frequently. You should be aware that Valganciclovir is also considered a potential cancer-causing agent, although this possible effect has not been studied. Valganciclovir can diminish fertility in both men and women. It may also prove harmful to a developing baby. Women should use birth control while taking Valganciclovir, and men should use condoms during treatment and for 90 days thereafter. Convulsions, sedation, dizziness, weakness, and confusion have been reported with the use of Valganciclovir tablets. If any of these symptoms occur, do not drive, operate machinery, or perform any other task that requires you to be alert. Valganciclovir is not a cure for CMV retinitis. You should have an eye exam at least every 4 to 6 weeks while being treated with Valganciclovir tablets. |
