Discover Stribild Dosage: Tailored Treatment for HIV-1 Infection

Stribild (elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate) is a prescription drug that’s used to treat HIV in certain situations. The drug comes as an oral tablet that you usually take once a day.

Stribild is approved for adults and some children to treat HIV. Specifically, it’s approved as a first treatment or to replace other HIV medications.

Before prescribing Stribild to replace other HIV medications, your doctor will confirm the following:

  • your viral load is undetectable, and
  • you’ve taken a stable treatment regimen for at least 6 months, and
  • your past treatments haven’t stopped working, and
  • your HIV hasn’t become resistant to any of Stribild’s active ingredients

* Viral load measures the amount of HIV in your blood. Doctors use this measure to help assess the effectiveness of treatment.
† If your HIV is resistant to any ingredients in Stribild, the drug may be less effective in treating your condition.

Stribild is a single-tablet HIV regimen. It contains four active ingredients in one tablet. (An active ingredient is what makes a drug work.) These are:

  • elvitegravir: an integrase inhibitor
  • cobicistat: a cytochrome P450 3A (CYP3A) inhibitor which boosts the levels of elvitegravir in your body
  • emtricitabine: a nucleoside reverse transcriptase inhibitor (NRTI)
  • tenofovir disoproxil fumarate: another NRTI

This article describes the dosage of Stribild, as well as its strengths and how to take it. To learn more about Stribild, see this in-depth article.

Boxed warning: Risk of worsening hepatitis B

Stribild has a boxed warning about the risk of worsening hepatitis B. A boxed warning is the most serious warning from the Food and Drug Administration (FDA).

If you have hepatitis B and HIV, your hepatitis B may become worse if you stop taking Stribild. The worsening of hepatitis B could be severe and may lead to liver failure.

Due to this risk, your doctor will test you for hepatitis B before you start taking Stribild. If you have hepatitis B, your doctor will monitor you for symptoms for several months after you stop taking Stribild.

Symptoms of hepatitis B may include:• fever
• dark urine
• jaundice

If you develop hepatitis B, your doctor may prescribe additional medication.
