Tenofovir disoproxil fumarate (TDF), a nucleotide reverse transcriptase inhibitor, is an analog of adenosine 5'-monophosphate; it interferes with the HIV viral RNA dependent DNA polymerase resulting in inhibition of viral replication. TDF is first converted intracellularly by hydrolysis to tenofovir and subsequently phosphorylated to the active tenofovir diphosphate. Tenofovir inhibits replication of HBV by inhibiting HBV polymerase.
Vd: 1.2-1.3 L/kg
Tenofovir disoproxil fumarate (TDF) is converted intracellularly by hydrolysis (by non-CYP enzymes) to tenofovir, then phosphorylated to the active tenofovir diphosphate
Urine (70% to 80%) via filtration and active secretion, primarily as unchanged tenofovir within 72 hours; after multiple oral doses (administered with food): 32% ± 10% is excreted in the urine within 24 hours
Clearance: Total body clearance is decreased in patients with renal impairment
Time to Peak
Serum: Fasting: 36-84 minutes; With high-fat meal: 96-144 minutes

Concerns related to adverse effects:
• Decreased bone mineral density: In clinical trials, use has been associated with decreases in bone mineral density in HIV-1 infected adults and increases in bone metabolism markers. Serum parathyroid hormone and 1,25 vitamin D levels were also higher. Decreases in bone mineral density have also been observed in clinical trials of HIV-1 infected pediatric patients. Observations in chronic hepatitis B infected pediatric patients (aged 12-18 years) were similar. In all pediatric clinical trials, skeletal growth (height) appears unaffected. Consider monitoring of bone density in adult and pediatric patients with a history of pathologic fractures or with other risk factors for bone loss or osteoporosis. Consider calcium and vitamin D supplementation for all patients; effect of supplementation has not been studied but may be beneficial. Long-term bone health and fracture risk unknown. If abnormalities are suspected, expert assessment is recommended.
• Fat redistribution: May cause redistribution of fat (eg, buffalo hump, peripheral wasting with increased abdominal girth, cushingoid appearance).
• Immune reconstitution syndrome: Patients may develop immune reconstitution syndrome resulting in the occurrence of an inflammatory response to an indolent or residual opportunistic infection during initial HIV treatment or activation of autoimmune disorders (eg, Graves’ disease, polymyositis, Guillain-Barré syndrome) later in therapy; further evaluation and treatment may be required.
• Lactic acidosis/hepatomegaly: [U.S Boxed Warning]: Lactic acidosis and severe hepatomegaly with steatosis have been reported with tenofovir and other nucleoside analogues, including fatal cases; use with caution in patients with risk factors for liver disease (risk may be increased with female gender, obesity, pregnancy or prolonged nucleoside exposure) and suspend treatment in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or hepatotoxicity (transaminase elevation may/may not accompany hepatomegaly and steatosis).
• Osteomalacia and renal dysfunction: May cause osteomalacia with proximal renal tubulopathy. Bone pain, extremity pain, fractures, arthralgias, weakness and muscle pain have been reported. In patients at risk for renal dysfunction, persistent or worsening bone or muscle symptoms should be evaluated for hypophosphatemia and osteomalacia.
• Pancreatitis: Pancreatitis has been reported; use with caution in patients with a prior history or risk factors for pancreatitis. Discontinue if pancreatitis is suspected.
• Renal toxicity: May cause renal toxicity (acute renal failure and/or Fanconi syndrome); avoid use with concurrent or recent nephrotoxic therapy (including high dose or multiple NSAID use). Acute renal failure has occurred in HIV-infected patients with risk factors for renal impairment who were on a stable tenofovir regimen to which a high dose or multiple NSAID therapy was added. Consider alternatives to NSAIDS in patients taking tenofovir and at risk for renal impairment. Calculate estimated creatinine clearance prior to initiation of therapy and monitor renal function (including recalculation of creatinine clearance and serum phosphorus) during therapy. In patients at risk for renal dysfunction, including patients who have experienced renal events while taking adefovir, assess serum phosphorus, urine glucose, and urine protein prior to and periodically during treatment. Dosage adjustment required in patients with CrCl <50 mL/minute. Use with caution in patients with low body weight or concurrent medications that increase tenofovir levels. IDSA guidelines recommend discontinuing tenofovir (and substituting with alternative antiretroviral therapy) in HIV-infected patients who develop a decline in GFR (a >25% decrease in GFR from baseline and to a level of <60 mL/minute/1.73 m2) during use, particularly in presence of proximal tubular dysfunction (eg, euglycemic glycosuria, increased urinary phosphorus excretion and hypophosphatemia, proteinuria [new onset or worsening]) (IDSA [Lucas 2014]).
• Chronic hepatitis B: [U.S. Boxed Warning]: Severe, acute exacerbation of hepatitis B may occur upon discontinuation. Monitor liver function several months after discontinuing treatment; reinitiation of antihepatitis B therapy may be required. Treatment of HBV in patients with unrecognized/untreated HIV may lead to HIV resistance; patients should be tested for presence of HIV infection prior to initiating therapy
• Hepatic impairment: Use with caution in patients with hepatic impairment. Limited data supporting treatment of chronic hepatitis B in patients with decompensated liver disease; observe for increased adverse reactions, including renal dysfunction.
• Renal impairment: Tenofovir is predominately eliminated renally. Use with caution in patients with renal impairment (CrCl <50 mL/minute); dosage adjustment required. IDSA guidelines recommend avoiding tenofovir in HIV patients with preexisting kidney disease (CrCl <50 mL/minute and not on hemodialysis or GFR <60 mL/minute/1.73 m2) when other effective HIV treatment options exist because data suggest risk of chronic kidney disease (CKD) is increased (IDSA [Lucas 2014]).
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Tenofovir combination products: Do not use concurrently with tenofovir combination products (ie, Atripla, Complera, Stribild, Truvada).
• Elderly: Use with caution in the elderly. Dosage adjustment based on renal function may be required.
• Pediatric: Decreases in bone mineral density may occur; long term effects are unknown. Skeletal growth (height) appears to be unaffected in tenofovir-treated children and adolescents.
• Appropriate use: Hepatitis B coinfection: Treatment of HIV in patients with unrecognized/untreated hepatitis B virus (HBV) may lead to rapid HBV resistance. Patients should be tested for presence of chronic hepatitis B infection prior to initiation of therapy. In patients coinfected with HIV and HBV, an appropriate antiretroviral combination should be selected due to HIV resistance potential; these patients should receive tenofovir dosed for HIV therapy.
• Appropriate use: HIV treatment: Do not use as monotherapy in treatment of HIV. Clinical trials in HIV-infected patients whose regimens contained only three nucleoside reverse transcriptase inhibitors (NRTI) show less efficacy, early virologic failure and high rates of resistance substitutions. Use three NRTI regimens with caution and monitor response carefully. Triple drug regimens with two NRTIs in combination with a non-nucleoside reverse transcriptase inhibitor or a HIV-1 protease inhibitor are usually more effective.
Patients with HIV: CBC with differential, reticulocyte count, creatine kinase, CD4 count, HIV RNA plasma levels, serum phosphorus; serum creatinine (prior to initiation and as clinically indicated during therapy), urine glucose and urine protein (in patients at risk for renal impairment or who experienced renal impairment while taking adefovir), hepatic function tests, bone density (patients with a history of bone fracture or have risk factors for bone loss); testing for HBV is recommended prior to the initiation of antiretroviral therapy; weight (children)
Patients with HBV: HIV status (prior to initiation of therapy); serum phosphorus; serum creatinine (prior to initiation and as clinically indicated during therapy), urine glucose and urine protein (in patients at risk for renal impairment or who experienced renal impairment while taking adefovir); bone density (patients with a history of bone fracture or have risk factors for bone loss); HBV DNA (every 3-6 months during therapy); HBeAg and anti-HBe; LFTs every 3 months during therapy and for several months following discontinuation of tenofovir; signs/symptoms of HBV relapse/exacerbation following discontinuation of therapy
Patients with HIV and HBV coinfection should be monitored for several months following tenofovir discontinuation.
Pregnancy Risk Factor
Adverse events were observed in some animal reproduction studies. Tenofovir has a high level of transfer across the human placenta. Intrauterine growth has not been affected in human studies, but data is conflicting about potential growth effects later in infancy. Clinical studies in children have shown bone demineralization with chronic use. Bone mineral content was also decreased in infants following in utero exposure. No increased risk of overall birth defects has been observed following first trimester exposure according to data collected by the antiretroviral pregnancy registry. Cases of lactic acidosis/hepatic steatosis syndrome related to mitochondrial toxicity have been reported with use of nucleoside analogues. In addition, these adverse events are similar to other rare but life-threatening syndromes which occur during pregnancy (eg, HELLP syndrome). In general nucleoside reverse transcriptase inhibitors are well tolerated and the benefits of use generally outweigh potential risk. The HHS Perinatal HIV Guidelines consider tenofovir in combination with either emtricitabine or lamivudine to be a preferred NRTI backbone for use in antiretroviral-naive pregnant women. The HHS Perinatal HIV Guidelines consider emtricitabine plus tenofovir, or lamivudine plus tenofovir as recommended dual NRTI/NtRTI backbones for HIV/HBV coinfected pregnant women. Hepatitis B flare may occur if tenofovir is discontinued postpartum. Limited data indicate decreased maternal exposure during the third trimester; dose adjustments are not needed.
Combination antiretroviral therapy (cART) therapy is recommended for all HIV-infected pregnant women. The goal of therapy is to keep the viral load below the limit of detection and prevent perinatal transmission. Therapy must be individualized. In general, women who become pregnant on a stable cART regimen may continue that regimen if viral suppression is effective, contraindications for use in pregnancy are not present, and the regimen is well tolerated. For HIV-infected couples planning a pregnancy, maximum viral suppression with cART is recommended prior to conception for the HIV-infected partner(s). When HIV is diagnosed during pregnancy in a woman who has never received antiretroviral therapy, cART should be considered as soon as possible after diagnosis to reduce the risk of perinatal transmission. If antiretroviral drug-resistance testing is done, treatment may be started prior to obtaining results, then adjusted accordingly. Monitoring during pregnancy is more frequent than in non-pregnant adults. If cART must be interrupted for <24 hours, stop then restart all medications simultaneously in order to decrease the chance of developing resistance. Long-term follow-up is recommended for all infants exposed to antiretroviral medications; children who develop significant organ system abnormalities (particularly of the CNS or heart) should be evaluated for potential mitochondrial dysfunction.
HIV-infected women not planning a pregnancy may use any available type of contraception, considering possible drug interactions and contraindications of the specific method. In addition, consistent use of condoms is also recommended (even during pregnancy) to prevent transmission of HIV or other sexually-transmitted diseases.
Health care providers are encouraged to enroll pregnant women exposed to antiretroviral medications as early in pregnancy as possible in the Antiretroviral Pregnancy Registry (1-800-258-4263 or www.APRegistry.com). Health care providers caring for HIV-infected women and their infants may contact the National Perinatal HIV Hotline (888-448-8765) for clinical consultation (HHS [perinatal] 2015).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache, dizziness, nausea, vomiting, diarrhea, insomnia, or loss of strength and energy. Have patient report immediately to prescriber signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), signs of kidney problems (urinary retention, blood in urine, change in amount of urine passed, or weight gain), signs of too much lactic acid in the blood (lactic acidosis; fast breathing, fast heartbeat, abnormal heartbeat, vomiting, drowsiness, shortness of breath, feeling very tired or weak, severe dizziness, feeling cold, or muscle pain or cramps), depression, bone pain, muscle pain, muscle weakness, painful extremities, change in body fat, or sign of infection (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
