Version July 2025
Severe acute exacerbations of hepatitis B have been reported in patients with HIV-1 and hepatitis B virus (HBV) who have discontinued products containing emtricitabine and/or tenofovir disoproxil fumarate, and may occur with discontinuation of emtricitabine/rilpivirine/tenofovir alafenamide.
Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients with HIV-1 and HBV who discontinue emtricitabine/rilpivirine/tenofovir alafenamide. If appropriate, anti-hepatitis B therapy may be warranted.
HIV-1 infection, treatment: Oral: One tablet (emtricitabine 200 mg/rilpivirine 25 mg/tenofovir alafenamide 25 mg) once daily. Note: Do not use in patients with HIV RNA ≥100,000 copies/mL and/or CD4 count ≤200 cells/mm3 (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Note: Renal function may be estimated using the Cockcroft-Gault formula for dosage adjustment purposes.
CrCl ≥30 mL/minute: No dosage adjustment necessary.
CrCl <30 mL/minute: Use is not recommended.
End-stage renal disease on hemodialysis: No dosage adjustment necessary; administer after hemodialysis on dialysis days.
Mild to moderate impairment (Child-Pugh class A or B): No dosage adjustments necessary.
Severe impairment (Child-Pugh class C): There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).
Refer to adult dosing.

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified. Also see individual agents.
1% to 10%:
Gastrointestinal: Diarrhea (1%), flatulence (≤1%), nausea (1%)
Nervous system: Abnormal dreams (1%), headache (2%), sleep disturbance (2%)
Neuromuscular & skeletal: Decreased bone mineral density (1% to 2%)
Frequency not defined: Endocrine & metabolic: Dyslipidemia
Concurrent use with certain drugs whose coadministration may result in loss of virologic response and possible resistance to emtricitabine/rilpivirine/tenofovir alafenamide or to the class of non-nucleoside reverse transcriptase inhibitors (eg, carbamazepine, systemic dexamethasone [>1 dose], oxcarbazepine, phenobarbital, phenytoin, proton pump inhibitors [dexlansoprazole, esomeprazole, lansoprazole, omeprazole, pantoprazole, rabeprazole], rifampin, rifapentine, St John's wort).
Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to emtricitabine, rilpivirine, tenofovir alafenamide, or any component of the formulation.
Concerns related to adverse effects:
• Depressive disorders: Rilpivirine may cause depression, depressed mood, dysphoria, major depression, mood changes, negative thoughts, suicide attempts, or suicidal ideation. Promptly evaluate patients with severe depressive symptoms and reevaluate risk versus benefit of continued combination therapy.
• Hepatotoxicity: Hepatotoxicity has been reported with rilpivirine-containing regimens. Patients with hepatitis B or C or increased baseline liver function tests may be at greater risk, although some cases have occurred in patients with no preexisting disease or hepatic disease risk factors. Evaluate liver function tests in patients with increased baseline liver function tests or with hepatitis B or C prior to treatment initiation and periodically during therapy; also consider evaluation of patients with no preexisting hepatic disease or hepatic disease risk factors.
• Hypersensitivity: Hypersensitivity and severe skin reactions have been reported, including drug reaction with eosinophilia and systemic symptoms (DRESS), with regimens containing rilpivirine. Some skin reactions were accompanied by constitutional symptoms (eg, fever); other skin reactions were associated with organ dysfunction (eg, hepatic serum biochemistry elevations). In clinical trials, treatment-related rashes ≥ grade 2 were reported in 1% of patients. Most rashes were grade 1 or 2 and occurred within the first 4 to 6 weeks of therapy. Monitor laboratory parameters and clinical status; discontinue if any severe hypersensitivity or skin rash (including, but not limited to, severe rash or rash accompanied by angioedema, blisters, conjunctivitis, eosinophilia, facial edema, fever, hepatitis, or mucosal involvement) develops.
• 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, autoimmune hepatitis) later in therapy; further evaluation and treatment may be required.
• Lactic acidosis/hepatomegaly: Lactic acidosis and severe hepatomegaly with steatosis, sometimes fatal, have been reported with the use of nucleoside analogs, alone or in combination with other antiretrovirals. Suspend treatment in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (marked transaminase elevation may/may not accompany hepatomegaly and steatosis).
• QT prolongation: In healthy subjects, supratherapeutic dosages of rilpivirine (75 mg once daily and 300 mg once daily) have been shown to prolong the QTc interval of the electrocardiogram; consider alternative therapy in patients at high risk for torsades de pointes or when coadministered with medications with known risk for torsades de pointes.
• Renal toxicity: Renal toxicity (acute renal failure, Fanconi syndrome, and/or proximal renal tubulopathy) has been reported with use of tenofovir alafenamide-containing products; most cases were characterized by potential confounders that may have contributed to the renal events; however, it is also possible these factors may have predisposed patients to tenofovir-related adverse events. Patients with impaired renal function and those with concurrent or recent nephrotoxic therapy (including NSAID use) are at an increased risk. Discontinue use in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome.
Disease-related concerns:
• Renal impairment: Use is not recommended in patients with CrCl <30 mL/minute (unless receiving hemodialysis).
Emtricitabine-associated hyperpigmentation occurs more frequently in pediatric patients (32%) than in adults.
Incidence of some adverse reactions may be higher in pediatric patients 12 to 18 years of age receiving rilpivirine as compared to adults. In a small, phase 2 pediatric clinical trial (n=36), adverse reactions following receipt of rilpivirine in combination with other antiretrovirals were similar to those in adults, with a higher incidence of some reactions (eg, headache, dizziness, depression); most were grade 1 or 2. For depressive disorders, the incidence of grade 3 and 4 depressive disorders (regardless of causality) was 5.6% (vs 1% in adults), including 1 suicide attempt. None of these pediatric patients discontinued therapy due to their depressive symptoms.
Through disruption in vitamin D metabolism, decreases in bone mineral density (BMD) have been observed with tenofovir alafenamide (TAF) after 48 weeks of treatment; however, the incidence and negative impact on BMD is less than that observed with tenofovir disoproxil fumarate (TDF). Additionally, TAF is associated with less renal toxicity than TDF but equal antiviral efficacy. A higher incidence of dyslipidemia has been reported with TAF than TDF. TAF is preferred over TDF whenever possible; do not use TAF and TDF concomitantly (HHS [pediatric] 2024).

This fixed-dose combination of emtricitabine, rilpivirine, and tenofovir alafenamide is an alternative regimen for patients with HIV who are not yet pregnant but are trying to conceive (HHS [perinatal] 2024).
Refer to individual monographs for additional information.
This fixed-dose combination of emtricitabine, rilpivirine, and tenofovir alafenamide is an alternative regimen for initiation in pregnant patients with HIV who are antiretroviral naive, who have had antiretroviral therapy (ART) in the past but are restarting, or who require a new ART regimen (due to poor tolerance or poor virologic response of current regimen). Patients who become pregnant while taking this combination may continue if viral suppression is effective and the regimen is well tolerated. More frequent monitoring (every 1 to 2 months) is recommended during pregnancy. This fixed-dose combination may be considered for patients when significant drug interactions would occur with preferred agents or in patients who need the convenience of a co-formulated single dose tablet in a once-daily regimen but are not eligible for preferred agents. This combination should only be used in pregnant patients with a pretreatment HIV RNA ≤100,000 copies/mL or CD4 cell count ≥200 cells/mm3 (HHS [perinatal] 2024).
Refer to individual monographs for additional information.
Emtricitabine, rilpivirine, and tenofovir are present in breast milk.
Refer to individual monographs for additional information.
Take with a meal.
CD4 count, HIV RNA plasma levels; serum creatinine, estimated creatinine clearance, urine glucose, urine protein (prior to initiation and as clinically indicated during therapy); serum phosphorus (patients with chronic kidney disease); hepatic function tests, bone density (patients with a history of bone fracture or have risk factors for bone loss); fever, skin reactions, and/or hypersensitivity reactions; HBV testing (prior to or when initiating therapy). Patients with HIV and HBV coinfection should be monitored for several months following therapy discontinuation.
Non-nucleoside, nucleoside, and nucleotide reverse transcriptase inhibitor combination; rilpivirine binds to reverse transcriptase and does not require intracellular phosphorylation for antiviral activity; emtricitabine is a cytidine analogue while tenofovir alafenamide fumarate (TAF) is an analog of adenosine 5'-monophosphate. Each drug interferes with HIV viral RNA dependent DNA polymerase activities resulting in inhibition of viral replication.
