In general, caution should be exercised in the administration and monitoring of Victrelis in geriatric patients due to the greater frequency of decreased hepatic function, concomitant diseases and other drug therapy No dosage adjustment of Victrelis is required for patients with any degree of renal impairment No dose adjustment of Victrelis is required for patients with mild, moderate or severe hepatic impairment In published observational studies of patients with compensated cirrhosis treated with first generation HCV protease inhibitors, including boceprevir, in combination with peginterferon alfa and ribavirin, platelet count < 100,000/mmThe potential risks and benefits of Victrelis in combination with peginterferon alfa and ribavirin should be carefully considered before initiating therapy in patients with compensated cirrhosis who have platelet count < 100,000/mmThe safety and efficacy of Victrelis alone or in combination with peginterferon alfa and ribavirin for the treatment of chronic hepatitis C genotype 1 infection in liver or other organ transplant recipients have not been studied. The racial distribution of subjects was as follows: 82% White, 14% Black, and 4% others. Look up information on diseases, tests, and procedures; then consult the database with 5,000+ drugs or refer to 65,000+ dictionary terms. The lack of detection of a substitution based on a population-based assay does not necessarily indicate that viral populations carrying that substitution have declined to a background level that may have existed prior to treatment.

No testicular degeneration was observed at a 15 mg per kg dose level resulting in boceprevir AUC exposures of less than those in humans at the recommended dose of 800 mg three times daily. … Coadministration of Victrelis with drugs that induce or inhibit CYP3A4/5 could decrease or increase exposure to boceprevir.Victrelis must be administered in combination with peginterferon alfa and ribavirin Significant teratogenic and/or embryocidal effects have been demonstrated in all animal species exposed to ribavirin; and therefore ribavirin is contraindicated in women who are pregnant and in the male partners of women who are pregnant Extreme caution must be taken to avoid pregnancy in female patients and female partners of male patients while taking this combination.
If such an acute reaction occurs, combination therapy should be discontinued and appropriate medical therapy immediately instituted HCV-RNA levels should be monitored at Treatment Weeks 4, 8, 12, and 24, at the end of treatment, during treatment follow-up, and for other time points as clinically indicated. The study enrolled subjects with serum hemoglobin concentrations of less than 15 g per dL. The same dosage schedule applies to adults and pediatric patients two years of age and older.
Adults:-If used with voriconazole: Decrease efavirenz dose to 300 mg orally once a day using the capsule formulation; the manufacturer product information should be consulted.-If used with rifampin in patients weighing 50 kg or more: Increase efavirenz dose to 800 mg orally once a day. One of these reliable forms of contraception can be a combined oral contraceptive product containing at least 1 mg of norethindrone. Human plasma protein binding is approximately 75% following a single dose of boceprevir 800 mg. Boceprevir is administered as an approximately equal mixture of two diastereomers, SCH534128 and SCH534129, which rapidly interconvert in plasma.

For more information, ask your healthcare provider or pharmacist.It is not known if treatment with Victrelis will prevent you from infecting another person with the hepatitis C virus during your treatment. Levels of boceprevir and/or metabolites in the milk of lactating rats were slightly higher than levels observed in maternal blood.
