HEALTH PROFESSIONAL INFORMATION SUMMARY PRODUCT INFORMATION Route of Administration Dosage Form/Strength All Nonmedicinal Ingredients Oral Tablet 300 mg Anhydrous lactose, calcium stearate, colloidal silicon dioxide, crospovidone, indigotine aluminum lake 12-14% (blue #2), polyethylene glycol, polyvinyl alcohol, talc and titanium dioxide INDICATIONS AND CLINICAL USE HIV-1 Infection TENOFOVIR (tenofovir disoproxil fumarate (TDF)) is indicated for the treatment of HIV-1 infection in combination with other antiretroviral agents in patients 12 years of age and older.
Chronic Hepatitis B TENOFOVIR is indicated for the treatment of chronic hepatitis B infection in patients 18 years of age and older, with: • Compensated liver disease, with evidence of active viral replication, with elevated serum alanine aminotransferase (ALT) levels or evidence of fibrosis (based on liver biopsy or a noninvasive procedure); • Evidence of lamivudine-resistant hepatitis B virus; or • Decompensated liver disease.
Geriatrics (>65 years of age) Clinical studies of tenofovir disoproxil fumarate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Pediatrics (12 to < 18 years of age) The safety and efficacy of tenofovir disoproxil fumarate in adolescent patients aged 12 to <18 years is supported by data from one randomized study in which tenofovir disoproxil fumarate was Page 4 of 62 administered to HIV-1 infected treatment experienced subjects.
In this study, the pharmacokinetic profile of tenofovir disoproxil fumarate was similar to that found to be safe and effective in adult populations. Safety and efficacy in pediatric patients less than 12 years of age have not been established.
CONTRAINDICATIONS TENOFOVIR (tenofovir disoproxil fumarate) is contraindicated in patients with previously demonstrated hypersensitivity to any of the components of the product. For a complete listing, see the DOSAGE FORMS, COMPOSITION AND PACKAGING section of the Product Monograph.

• Post-Treatment Exacerbation of Hepatitis B Severe acute exacerbations of hepatitis have been reported in HBV-infected patients who have discontinued anti-hepatitis B therapy, including tenofovir disoproxil fumarate. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy, including TENOFOVIR.
If appropriate, resumption of anti-hepatitis B therapy may be warranted (see WARNINGS AND PRECAUTIONS, Hepatic/Biliary/Pancreatic). • Nephrotoxicity Renal impairment, including cases of acute renal failure and Fanconi syndrome (renal tubular injury with severe hypophosphatemia), has been reported with the use of tenofovir disoproxil fumarate during clinical practice (see WARNINGS AND PRECAUTIONS, Renal).
General For the effect of coadministered drugs, see DRUG INTERACTIONS section. Clinical studies in HIV-infected patients have demonstrated that certain regimens that only contain three nucleoside reverse transcriptase inhibitors (NRTI) are generally […]
