Biktarvy is a prescription medication primarily used to treat HIV-1 infection in adults and certain children. It is a complete once-daily treatment that combines three antiviral drugs in a single tablet. The goal of Biktarvy therapy is to suppress the HIV virus, maintain a healthy immune system, and prevent the progression of HIV to AIDS (Acquired Immunodeficiency Syndrome).
It’s considered one of the most effective and convenient options for HIV treatment because it simplifies therapy into one pill per day, without needing to combine multiple medications.
What Is HIV-1 and Why Is Biktarvy Important?
HIV-1 (Human Immunodeficiency Virus type 1) is the most common type of HIV worldwide. It attacks the body’s immune system, specifically CD4 T-cells, which are crucial for fighting infections.
If left untreated, HIV gradually weakens the immune system, making the body more vulnerable to infections and diseases.
Biktarvy helps people living with HIV lead longer, healthier lives by stopping the virus from multiplying and allowing the immune system to recover.

What’s in Biktarvy?
Each Biktarvy tablet contains a combination of three active ingredients:
- Bictegravir (50 mg) – an integrase strand transfer inhibitor (INSTI) that blocks HIV from integrating its genetic material into human DNA.
- Emtricitabine (200 mg) – a nucleoside reverse transcriptase inhibitor (NRTI) that stops the virus from making new copies of itself.
- Tenofovir alafenamide (25 mg) – another NRTI that helps strengthen the effect of emtricitabine and provides long-lasting viral suppression with fewer kidney and bone side effects.
Together, these drugs target different stages of the HIV life cycle, effectively stopping the virus from reproducing.
Biktarvy Is Used For:
1. Treating HIV-1 Infection in Adults
Biktarvy is approved for use in adults with HIV-1 infection who:
- Have never received antiretroviral therapy (ART) before (treatment-naive), or
- Are replacing their current HIV regimen and have an undetectable viral load (less than 50 copies/mL).
This makes Biktarvy a preferred first-line treatment in HIV guidelines because of its high effectiveness, safety profile, and convenience.
2. Treating HIV-1 Infection in Children
Biktarvy is also prescribed for children aged 6 years and older who weigh at least 25 kg (55 lbs) and meet the same treatment criteria as adults.
3. Maintaining Viral Suppression
For patients already on HIV treatment, switching to Biktarvy helps maintain viral suppression without the need for multiple pills. Studies show that Biktarvy keeps viral loads undetectable in over 97% of patients after 48 weeks of use.
How Biktarvy Works
HIV multiplies by inserting its genetic material into the DNA of human cells. Biktarvy stops this process through a three-way mechanism:
- Bictegravir blocks the integration of viral DNA.
- Emtricitabine stops the creation of new viral RNA.
- Tenofovir alafenamide strengthens the antiviral effect and ensures the virus cannot replicate efficiently.
By attacking HIV at multiple points, Biktarvy reduces the amount of virus in the blood (viral load) to undetectable levels, helping restore immune function and reducing the risk of transmission.
Benefits of Biktarvy
- Once-daily tablet – no need for multiple HIV medicines.
- Strong antiviral protection – helps achieve and maintain undetectable viral load.
- Fewer side effects – compared to older HIV drugs.
- Better kidney and bone safety – thanks to tenofovir alafenamide (TAF).
- No food restrictions – can be taken with or without food.
- Compatible with many medications – though some drug interactions still exist.
Patients appreciate its simplicity, which improves medication adherence and long-term outcomes.
Who Should Use Biktarvy
You may be prescribed Biktarvy if you:
- Have recently been diagnosed with HIV-1
- Want to simplify your existing HIV treatment
- Have no known resistance to the components of Biktarvy
It’s important that your healthcare provider performs resistance testing before starting the medication to ensure Biktarvy will work effectively for your viral strain.
Who Should NOT Use Biktarvy
Biktarvy is not suitable for everyone. Avoid or use with caution if you:
- Have severe liver disease or kidney failure
- Take certain anticonvulsants (carbamazepine, phenytoin) or rifampin
- Are allergic to any of its components
- Have hepatitis B infection and plan to stop therapy suddenly (this can worsen the liver condition)
Your doctor may adjust your dosage or monitor your organs more closely if you have any underlying health issues.
How to Take Biktarvy
- Take one tablet daily, with or without food.
- Try to take it at the same time each day to maintain consistent blood levels.
- Do not skip or double doses. If you miss a dose and remember within 18 hours, take it right away; if more time has passed, skip it and continue as usual.
- Avoid taking it with antacids or supplements containing magnesium or aluminum within 2 hours, as they can affect absorption.

Possible Side Effects
While generally well-tolerated, Biktarvy may cause:
- Headache
- Nausea
- Diarrhea
- Trouble sleeping
- Fatigue
Serious side effects are rare but can include:
- Liver problems
- Lactic acidosis
- Mood changes or depression
- Kidney or bone issues (uncommon with TAF)
If you notice yellowing of eyes, dark urine, severe tiredness, or muscle pain, seek medical help immediately.
How Effective Is Biktarvy?
In clinical trials, over 97% of adults taking Biktarvy achieved undetectable viral loads within 12 months, showing it’s one of the most potent and reliable HIV treatments available today.
When taken consistently, it helps patients live long, healthy lives and prevents HIV transmission to others.
Key Takeaway
Biktarvy is a modern, once-daily HIV-1 treatment that combines three effective antiviral medicines to stop the virus from multiplying and protect your immune system. It’s used for both newly diagnosed patients and those maintaining viral suppression.
With its powerful efficacy, minimal side effects, and simple dosing, Biktarvy remains one of the most trusted HIV therapies worldwide.
