About Biktarvy: This combination product is used by itself to help control HIV infection. Show more ▾

It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. This product is a combination of 3 different drugs: bictegravir, emtricitabine, and tenofovir alafenamide. Bictegravir is called an integrase strand transfer inhibitor-INSTI. Emtricitabine is called a nucleoside reverse transcriptase inhibitor, while tenofovir alafenamide is called a nucleotide reverse transcriptase inhibitor. Emtricitabine and tenofovir alafenamide are often called NRTIs. Bictegravir/emtricitabine/tenofovir alafenamide is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor. Do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.

About this data. The prescription history for MASAYUKI NIGO M.D. is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release. Figures cover prescriptions filled for Medicare Part D beneficiaries only; prescriptions under private insurance, Medicaid, or self-pay plans are not included. Because prescribing decisions are generally consistent across coverage types, this record offers a useful view of the overall Infectious Disease prescribing approach at this Houston, TX practice.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average volume among TX prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
