Cobicistat, Elvitegravir, Emtricitabine, And Tenofovir (Genvoya)

Genvoya is a tablet containing a combination of cobicistat, elvitegravir, emtricitabine, and tenofovir.

Cobicistat reduces the action of enzymes in your liver that break down certain antiviral medicines. This allows the antiviral medicines to be used more safely and effectively at lower doses.

Elvitegravir, emtricitabine and tenofovir are antiviral medicines that prevent human immunodeficiency virus (HIV) from multiplying in your body. HIV can cause acquired immunodeficiency syndrome (AIDS).

Genvoya is used to treat HIV in adults and children who are at least 12 years old and who weigh at least 55 pounds (25 kilograms).

Genvoya is not a cure for HIV or AIDS.

Important Information

Genvoya can harm your liver. Call your doctor at once if you have: upper stomach pain, loss of appetite, dark urine, clay-colored stools, or yellowing of your skin or eyes.

Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together.

Do not stop using Genvoya without your doctor’s advice. Get your prescription refilled before you run out of medicine completely.

If you’ve ever had hepatitis B, it may become active or get worse after you stop using Genvoya. You may need frequent liver function tests for several months.

Many drugs can interact with this medicine and some should not be used at the same time. Tell your doctor about all the medicines you use.

You should not take Genvoya if you are allergic to cobicistat, elvitegravir, emtricitabine, or tenofovir.

To make sure Genvoya is safe for you, tell your doctor if you have ever had:

  • hepatitis B or other liver problems;
  • kidney disease; or
  • bone problems.

You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, if you’ve taken HIV medication for a long time, or if you are a woman. Ask your doctor about your risk.

This medicine may not work as well if you take it during pregnancy. Do not start taking the medicine if you are pregnant. Tell your doctor right away if you become pregnant.

If you plan to get pregnant, ask your doctor for another antiviral medicine to use during pregnancy. Use all medications properly to control your infection.

HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of antiviral medicine on the baby.

If you do not plan to get pregnant, ask your doctor about using a non- hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy. Cobicistat, elvitegravir, emtricitabine, and tenofovir can increase certain side effects when taken with hormonal birth control (pills, injections, implants, skin patches, vaginal rings).

Women with HIV or AIDS should not breast feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.

How To Take Genvoya

Genvoya is usually taken once per day. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Take with food.

You will need frequent medical tests. Your kidney function may also need to be checked.

Use Genvoya regularly to get the most benefit. Your disease may become resistant if you miss doses. Do not change your dose or dosing schedule without your doctor’s advice. Every person with HIV should remain under the care of a doctor.

Store in the original container at room temperature, away from moisture and heat. Keep the bottle tightly closed when not in use.

If you’ve ever had hepatitis B, this virus may become active or get worse in the months after you stop using Genvoya. You may need frequent liver function tests while using Genvoya and for several months after your last dose.

Usual Dose of Genvoya for HIV Infection: 1 tablet orally once a day with food

If You Miss A Dose

Get your prescription refilled before you run out of medicine completely.

What To Avoid While Taking Genvoya

Avoid taking an antacid within 2 hours before or 2 hours after you take Genvoya. Some antacids can make it harder for your body to absorb this medicine.

Using Genvoya will not prevent your disease from spreading. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.
