What is GENVOYA
How GENVOYA works
GENVOYA tablets consist of the following four medicines:
- tenofovir alafenamide
These are combined in one tablet to help control Human Immunodeficiency Virus (HIV) infection.
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.
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).
Elvitegravir, cobicistat and emtricitabine are also components of STRIBILD® tablets.
Use in children
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.
Does GENVOYA cure HIV or AIDS
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.
Before you take GENVOYA
When you must not take it
Together with your doctor, you need to decide whether GENVOYA is right for you. There are complex interactions with many different medications, so you should consult your doctor or pharmacist before starting any new medication.

Before you start to take it
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have, or have had, any of the following medical conditions:
- severe kidney problems or are undergoing kidney dialysis treatment.
- liver problems, including hepatitis B or C virus infection.
Tell your doctor if you take an antacid medicine that contains aluminium, magnesium hydroxide, or calcium carbonate.
Take antacids at least 2 hours before or after you take GENVOYA.
Tell your doctor if you are pregnant, or likely to become pregnant during your course of medication. 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.
Tell your doctor if you are breastfeeding, or likely to breastfeed during your course of medication. 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.
Taking other medicines
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.
How to take GENVOYA
Take the exact amount of GENVOYA your doctor has prescribed for you.
Never change the dose on your own.
Do not stop this medicine unless your healthcare provider tells you to stop.
How much to take
The usual dose is one GENVOYA tablet orally, once daily.
Always take GENVOYA with food.
If you forget to take it
Do not miss a dose of GENVOYA.
If you forget to take GENVOYA, 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 a forgotten dose.
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 take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre: 131126 (Australia) and 0800 764 766 (New Zealand) or go to the Accident and Emergency department at your nearest hospital if you think you or anyone else may have taken too many GENVOYA tablets. Do this even if there are no signs of discomfort or poisoning. This may need urgent medical attention.
While you are taking GENVOYA
Things you must not do
Do not breastfeed. See “Before you start to take it”
Avoid doing things that can spread HIV infection since GENVOYA does not stop you from passing the HIV Infection to others.
- Do not share needles or other injection equipment.
- Do not share personal items that can have blood or body fluids on them, like toothbrushes or razor blades.
- Do not have any kind of sex without protection.
Always practice safer sex by using a latex or polyurethane condom or other barrier to reduce the chance of sexual contact with semen, vaginal secretions, or blood.
Do not take GENVOYA after the expiry or “use by” date (EXP) printed on the bottle. If you take it after the expiry date has passed, it may not work as well.
Do not take GENVOYA if the packaging is torn or shows signs of tampering.
Things to be careful of
Be careful driving or operating machinery until you know how GENVOYA affects you.
If you are dizzy, have trouble concentrating, or are drowsy, avoid activities that may be dangerous, such as driving or operating machinery.
Like all medicines, GENVOYA can have side effects, although not everybody gets them. Some may be serious and need medical attention.
Check with your doctor as soon as possible if you have any problems while taking GENVOYA, even if you do not think the problems are connected with the medicine or are not listed in this leaflet.
Serious side effects
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.
If you have any of the following symptoms after taking your medication, tell your doctor IMMEDIATELY or go to the accident and emergency department at your nearest hospital.:
- 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)
If you have any of the following symptoms while taking your medication, tell your doctor IMMEDIATELY or go to the accident and emergency department at your nearest hospital.
- 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
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.
