HIV Infections - virologically-suppressed pregnant individuals One tablet (50 mg BIC/200 mg FTC/25 mg TAF) taken orally once daily with or without food; monitor viral load closely due to lower drug exposures during pregnancy.
HIV Infections (treatment-naive adults) 300 mg once daily with ritonavir 100 mg once daily with food, or 400 mg once daily with food if unable to tolerate ritonavir
HIV Infections (treatment-experienced adults) 300 mg once daily with ritonavir 100 mg once daily with food; 400 mg once daily with ritonavir 100 mg once daily if taken with both tenofovir DF and H2-receptor antagonist

Contraindications
- Co-administration with dofetilide due to potential for increased dofetilide plasma concentrations and serious or life-threatening events
- Co-administration with rifampin due to substantially decreased BIC plasma concentrations, which may result in loss of therapeutic effect and development of resistance
- Previously demonstrated clinically significant hypersensitivity (eg, Stevens-Johnson syndrome, erythema multiforme, toxic skin eruptions) to any component
- Coadministration with drugs highly dependent on CYP3A or UGT1A1 for clearance where elevated plasma concentrations are associated with serious or life-threatening events (alfuzosin, cisapride, pimozide, orally administered midazolam, triazolam, ergot derivatives, lovastatin, simvastatin, lomitapide, sildenafil for pulmonary arterial hypertension, indinavir, irinotecan, lurasidone when boosted with ritonavir, apalutamide, encorafenib, ivosidenib, elbasvir/grazoprevir, glecaprevir/pibrentasvir)
- Coadministration with strong CYP3A inducers (rifampin, St. John's wort, carbamazepine, phenobarbital, phenytoin, nevirapine)

Pharmacology
BIKTARVY is a fixed-dose combination antiretroviral containing bictegravir (BIC), an integrase strand transfer inhibitor (INSTI) that blocks integration of HIV-1 DNA into host genomic DNA, plus emtricitabine (FTC) and tenofovir alafenamide (TAF), both nucleoside analog reverse transcriptase inhibitors (NRTIs) that terminate viral DNA chain elongation by competing with natural nucleoside substrates.
Atazanavir is an azapeptide HIV-1 protease inhibitor that selectively inhibits virus-specific processing of viral Gag and Gag-Pol polyproteins in HIV-1-infected cells, preventing formation of mature virions.
