Adefovir dipivoxil tablets are indicated for the treatment of chronic hepatitis B in patients 12 years of age and older with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active disease. This indication is based on histological, virological, biochemical, and serological responses in adult patients with HBeAg+ and HBeAg- chronic hepatitis B with compensated liver function, and with clinical evidence of lamivudine-resistant hepatitis B virus with either compensated or decompensated liver function. For patients 12 to less than 18 years of age, the indication is based on virological and biochemical responses in patients with HBeAg+ chronic hepatitis B virus infection with compensated liver function. Adefovir dipivoxil tablets are a nucleotide analogue indicated for the treatment of chronic hepatitis B in patients 12 years of age and older. ( 1 )

Severe acute exacerbations of hepatitis: Monitor hepatic function closely at repeated intervals for at least several months in patients who discontinue adefovir dipivoxil. ( 5.1 ) Nephrotoxicity: Monitor renal function during therapy for all patients, particularly those with pre-existing or other risks for renal impairment. Dose adjustment may be required. ( 5.2 ) HIV Resistance: Offer HIV testing to all patients prior to initiating adefovir dipivoxil. Untreated HIV may result in HIV resistance. ( 5.3 ) Lactic acidosis and severe hepatomegaly with steatosis: If suspected, suspend treatment. ( 5.4 ) Coadministration with Other Products: Do not administer adefovir dipivoxil concurrently with VIREAD ® or other tenofovir-containing products. ( 5.5 ) Clinical Resistance: For patients with lamivudine-resistant HBV use adefovir dipivoxil in combination with lamivudine. For all patients, consider modifying treatment in case serum HBV DNA remains above 1000 copies/mL with continued treatment. ( 5.6 ) 5.1 Exacerbation of Hepatitis after Discontinuation of Treatment Severe acute exacerbation of hepatitis has been reported in patients who have discontinued anti-hepatitis B therapy, including therapy with adefovir dipivoxil. Hepatic function should be monitored at repeated intervals with both clinical and laboratory follow-up for at least several months in patients who discontinue adefovir dipivoxil. If appropriate, resumption of anti-hepatitis B therapy may be warranted. In clinical …

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to adefovir dipivoxil during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258- 4263. Risk Summary Prospective pregnancy data from the APR are not sufficient to adequately assess the risk of birth defects, miscarriage or adverse maternal or fetal outcomes. Adefovir disoproxil (ADV) use during pregnancy has been evaluated in a limited number of individuals reported to the APR and the number of exposures to adefovir is insufficient to make a risk assessment compared to a …
