1. Why am I using GENVOYA?

GENVOYA contains the active ingredients elvitegravir, cobicistat, emtricitabine and tenofovir alafenamide in a single tablet.

Elvitegravir belongs to a class of antiviral medicines known as integrase inhibitors.

Cobicistat is a “booster”, to help increase the levels of elvitegravir.

Emtricitabine and tenofovir alafenamide belong to a group of antiviral medicines known as nucleoside and nucleotide reverse transcriptase inhibitors (NRTI).

GENVOYA is used to treat Human Immunodeficiency Virus 1 (HIV-1) infection in adults and children weighing at least 25 kg.

GENVOYA helps block HIV-1 reverse transcriptase, a viral chemical in your body (enzyme) that is needed for HIV-1 to multiply.

GENVOYA lowers the amount of HIV in the blood (viral load). GENVOYA may also help to increase the number of T cells (CD4+ cells), allowing your immune system to improve. Lowering the amount of HIV in the blood lowers the chance of death or infections that happen when your immune system is weak (opportunistic infections).

HIV infection destroys CD4 T cells, which are important to the immune system. The immune system helps fight infection. After a large number of T cells are destroyed, acquired immune deficiency syndrome (AIDS) may develop.

GENVOYA is for people who do not have a resistant HIV virus to GENVOYA.

This is not a complete list of medicines that you should not take with GENVOYA. You should discuss this with your doctor.

Check with your doctor if you:

  • have severe kidney problems or are undergoing kidney dialysis treatment
    – Your doctor should do blood and urine tests to check your kidneys when starting and during treatment with GENVOYA. Your doctor may tell you to stop taking GENVOYA if you develop new or worse kidney problems.
  • have problems, including hepatitis B or C virus infection
  • take any medicines for any other condition

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant. We do not know if GENVOYA can harm your unborn child. You and your doctor will need to decide if GENVOYA is right for you.

Talk to your doctor if you are breastfeeding or intend to breastfeed. You should not breastfeed if you are HIV-positive because of the chance of passing the HIV virus to your baby. One of the active substances in this medicine (emtricitabine) has been found in breast milk at low concentrations. Talk with your doctor about the best way to feed your baby.

Use in Children and Elderly

  • GENVOYA is used to treat HIV-1 infection in adults and children 6 years of age and older.
  • GENVOYA has not been studied in children under the age of 6 or weighing less than 25 kg, or adults over the age of 65.
  • GENVOYA has not been studied in children and adolescents under the age of 18 who have both HIV-1 and HBV infections.


GENVOYA does not cure HIV infection or AIDS.

The long-term effects of GENVOYA are not known at this time.

People taking GENVOYA may still get opportunistic infections or other conditions that happen with HIV infection.

Opportunistic infections are infections that develop because the immune system is weakened. Some of these conditions are pneumonia, herpes virus infections, and Mycobacterium avium complex (MAC) infection.

This medicine is only available from a pharmacist after it has been prescribed by a doctor who specialises in the treatment of HIV infection.

If you wish to continue receiving treatment with GENVOYA it is important you remain under the care of a hospital or doctor who specialises in the treatment of HIV infection.

Does GENVOYA reduce the risk of passing HIV to others?

It is still possible to pass on HIV to other people through sexual contact, sharing needles, or being exposed to your blood when taking GENVOYA, although the risk is much lower with effective antiretroviral therapy.

Discuss with your doctor the precautions needed to avoid infecting other people. For your health and the health of others, it is important to always practice safer sex by using a latex or polyurethane condom of other barrier to lower the chance of sexual contact with semen, vaginal secretions, or blood.

Never re-use or share needles.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may affect the levels of GENVOYA or GENVOYA may affect the levels of other medicines in the body when they are taken at the same time as GENVOYA.

Your doctor may change your other medicines or change their doses. Other medicines, including herbal products may affect GENVOYA.

For this reason, it is very important to let your doctor or pharmacist know what medications, herbal supplements, or vitamins you are taking.

Know the medicines you take. Keep a list of medicines and show it to your doctor and pharmacist when you get a new medicine.

Your doctor and your pharmacist can tell you if you can take these medicines with GENVOYA.

Do not start any new medicines while you are taking GENVOYA without first talking with your doctor or pharmacist.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect GENVOYA.

4. How do I use GENVOYA?

How much to take

  • The usual dose is one GENVOYA tablet orally, once daily.
  • Take GENVOYA with food.
  • Follow the instructions provided and use GENVOYA until your doctor tells you to stop.

If you forget to use GENVOYA

GENVOYA should be used regularly at the same time each day. It is important not to miss a dose of GENVOYA. If you miss your dose at the usual time, take your missed dose right away unless it is almost time for your next dose.

Do not take a double dose to make up for the dose you missed.

Continue with your regular dosing schedule.

When your GENVOYA supply starts to run low, get more from your doctor or pharmacy.

This is very important because the amount of virus in your blood may increase if the medicine is stopped for even a short time. The virus may develop resistance to GENVOYA and become harder to treat.

If you use too much GENVOYA

If you think that you have used too much GENVOYA, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre by calling 13 11 26 (Australia) and 0800 764 766 (New Zealand), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

6. Are there any side effects?

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.

Less serious side effects

Less serious side effects What to do
  • nausea
  • diarrhoea
  • fatigue
  • headaches
  • abdominal pain
  • indigestion
  • flatulence
  • rash
  • vomiting
Speak to your doctor if you have any of these less serious side effects and they worry you.

Serious side effects

Serious side effects What to do
Hepatic Flares
If you have HIV infection and HBV infection you should not stop your GENVOYA treatment without first discussing this with your doctor. Your HBV may get worse (flare-up) if you stop taking GENVOYA. A “flare-up” or “hepatic flare” is when your HBV infection suddenly returns in a worse way than before. You may require medical exams and blood tests for several months after stopping treatment. GENVOYA is not approved for the treatment of HBV, so you must discuss your HBV therapy with your doctor.

Signs and Symptoms of Inflammation
In some patients with advanced HIV infection (AIDS), signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to an improvement in the body’s immune response, which lets the body fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please tell your doctor immediately.

Lactic Acidosis

  • you feel very weak or tired
  • you have unusual (not normal) muscle pain
  • you have trouble breathing
  • you have stomach pain with nausea and vomiting
  • you feel cold, especially in your arms and legs
  • you feel dizzy or light headed
  • you have a fast or irregular heartbeat

These side effects may be due to a condition called lactic acidosis (build-up of an acid in the blood).
Lactic acidosis can be a medical emergency and may need to be treated in the hospital.

Serious Liver Problems (hepatotoxicity)

  • your skin or the white part of your eyes turns yellow (jaundice)
  • your urine turns dark
  • your bowel movements (stools) turn light in colour
  • you don’t feel like eating food for several days or longer
  • you feel sick to your stomach (nausea)
  • you have lower stomach area (abdominal) pain

These side effects may be due to a condition called hepatotoxicity with liver enlargement (hepatomegaly) and fat deposits in the liver (steatosis) which sometimes occurs in patients taking anti-HIV medicines.

Some people are allergic to medicines. If you have any of the following symptoms soon after taking your medicine, DO NOT TAKE ANY MORE GENVOYA and tell your doctor IMMEDIATELY or go to the accident and emergency department at your nearest hospital:

  • skin troubles such as lumpy skin rash or “hives”
  • swelling of the face, lips, mouth or throat which may cause difficulty in swallowing or breathing
  • wheezing, chest pain or tightness
  • fainting

These are very serious effects. If you have them, you may have a serious allergic reaction. You may need urgent medical attention or hospitalisation. Hypersensitivity reactions are very rare.

Call your doctor straight away, or go straight to the Emergency Department at your nearest hospital if you notice any of these serious side effects.

Tell your doctor or pharmacist if you notice anything else that may be making you feel unwell.

Other side effects not listed here may occur in some people.

Ask your doctor or pharmacist for a more complete list of side effects of GENVOYA and all the medicines you will take.
