1. What Genvoya is and what it is used for

Genvoya contains four active substances:

• elvitegravir, an antiretroviral medicine known as an integrase inhibitor
• cobicistat, a booster (enhancer) of the effects of elvitegravir
• emtricitabine, an antiretroviral medicine known as a nucleoside reverse transcriptase inhibitor

(NRTI)

• tenofovir alafenamide, an antiretroviral medicine known as a nucleotide reverse transcriptase inhibitor (NtRTI)

Genvoya is a single tablet for the treatment of human immunodeficiency virus 1 (HIV-1) infection in adults, adolescents and children 6 years of age and older, who weigh at least 25 kg.

Genvoya reduces the amount of HIV in your body. This will improve your immune system and reduce the risk of developing illnesses linked to HIV infection.

Warnings and precautions

You must remain under the care of your doctor while taking Genvoya.

You can still pass on HIV when taking this medicine, although the risk is lowered by effective antiretroviral therapy. Discuss with your doctor the precautions needed to avoid infecting other people. This medicine is not a cure for HIV infection. While taking Genvoya you may still develop infections or other illnesses associated with HIV infection.

Talk to your doctor before taking Genvoya:

• If you have liver problems or a history of liver disease, including hepatitis. Patients with liver disease including chronic hepatitis B or C, who are treated with antiretrovirals, have a higher risk of severe and potentially fatal liver complications.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

• Tell your doctor immediately if you are pregnant, think you may be pregnant or are

planning to have a baby. Pregnant women should not take Genvoya. The amount of this medicine in your blood may decrease during pregnancy which may stop it from working properly.

• Use effective contraception while taking Genvoya.
• Do not breast-feed during treatment with Genvoya. This is because some of the active substances in this medicine pass into human breast milk. It is recommended that you do not breast-feed to avoid passing the virus to the baby in breast milk.

Genvoya can cause dizziness. If you feel dizzy when taking Genvoya, do not drive or ride a bicycle and do not use any tools or machines.

Genvoya contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

^ If any of these applies to you, talk to your doctor before taking Genvoya.

3. How to take Genvoya

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is:

Adults: one tablet each day with food

Adolescents and children 6 years of age and older, who weigh at least 25 kg: one tablet each day with food

Due to the bitter taste, it is recommended not to chew or crush the tablet.

If you have difficulty swallowing the tablet whole, you can split it in half. Take both halves of the tablet one after the other to get the full dose. Do not store the split tablet.

Always take the dose recommended by your doctor. This is to make sure that your medicine is fully effective, and to reduce the risk of developing resistance to the treatment. Do not change the dose unless your doctor tells you to.

Do not take antacids or multivitamins at the same time as Genvoya. If you are taking medicines, oral supplements, antacids or laxatives containing minerals (such as magnesium, aluminium, calcium, iron, zinc), take them at least 4 hours before or at least 4 hours after Genvoya.

If you are on dialysis , take your daily dose of Genvoya following completion of dialysis.

If you take more Genvoya than you should

If you accidentally take more than the recommended dose of Genvoya you may be at increased risk of experiencing possible side effects with this medicine (see section 4, Possible side effects ).

Contact your doctor or nearest emergency department immediately for advice. Keep the tablet bottle with you so that you can easily describe what you have taken.

If you forget to take Genvoya

It is important not to miss a dose of Genvoya.

If you do miss a dose:

• If you notice within 18 hours of the time you usually take Genvoya, you must take the tablet as soon as possible. Always take the tablet with food. Then take the next dose as usual.
• If you notice 18 hours or more after the time you usually take Genvoya, then do not take the missed dose. Wait and take the next dose, with food, at your usual time.

If you vomit less than 1 hour after taking Genvoya, take another tablet with food.

Do not stop taking Genvoya

Do not stop taking Genvoya without talking to your doctor. Stopping Genvoya can seriously affect your response to future treatment. If Genvoya is stopped for any reason, speak to your doctor before you restart taking Genvoya tablets.

When your supply of Genvoya starts to run low, get more from your doctor or pharmacist. This is very important because the amount of virus may start to increase if the medicine is stopped for even a short time. The disease may then become harder to treat.

If you have both HIV infection and hepatitis B, it is especially important not to stop your Genvoya treatment without talking to your doctor first. You may require blood tests for several months after stopping treatment. In some patients with advanced liver disease or cirrhosis, stopping treatment is not recommended as this may lead to worsening of your hepatitis, which may be life-threatening.

^ Tell your doctor immediately about new or unusual symptoms after you stop treatment, particularly symptoms you associate with hepatitis B infection.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Possible serious side effects: tell a doctor immediately

• Any signs of inflammation or infection. In some patients with advanced HIV infection (AIDS) and a history of opportunistic infections (infections that occur in people with a weak immune system), signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is thought that these symptoms are due to an improvement in the body’s immune response, enabling the body to fight infections that may have been present with no obvious symptoms.
• Autoimmune disorders, when the immune system attacks healthy body tissue, may also occur after you start taking medicines for HIV infection. Autoimmune disorders may occur many months after the start of treatment. Look out for any symptoms of infection or other symptoms such as:

• – muscle weakness

• – weakness beginning in the hands and feet and moving up towards the trunk of the body

• – palpitations, tremor or hyperactivity.

^ If you notice the side effects described above, tell your doctor immediately.

Very common side effects

(may affect more than 1 in 10 people )

• feeling sick (nausea)

Common side effects

(may affect up to 1 in 10 people )

• abnormal dreams
• headache
• dizziness
• diarrhoea
• vomiting
• stomach pain

wind (flatulence ) rash

Uncommon side effects

^ If any of the side effects get serious tell your doctor.

Other effects that may be seen during HIV treatment

The frequency of the following side effects is not known (frequency cannot be estimated from the available data).

• Bone problems. Some patients taking combination antiretroviral medicines such as Genvoya may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). Taking this type of medicine for a long time, taking corticosteroids, drinking alcohol, having a very weak immune system, and being overweight, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are: – joint stiffness

• – joint aches and pains (especially of the hip, knee and shoulder)

• – difficulty with movement

5. How to store Genvoya
