1. What EVOTAZ is and what it is used for

EVOTAZ contains two active substances:

  • atazanavir, an antiviral (or antiretroviral) medicine. It is one of a group called protease inhibitors. These medicines control human immunodeficiency virus (HIV) infection by stopping production of a protein that HIV needs for its multiplication. They work by reducing the amount of HIV in your body and this in turn, strengthens your immune system. In this way atazanavir reduces the risk of developing illnesses linked to HIV infection.
  • cobicistat, a booster (pharmacokinetic enhancer) to help improve the effects of atazanavir. Cobicistat, does not directly treat your HIV, but boosts the levels of atazanavir in the blood. It does this by slowing down the breakdown of atazanavir which will make it stay in the body for longer.

EVOTAZ may be used by adults and adolescents (aged 12 years and older weighing at least 35 kg), who are infected with HIV, the virus that causes acquired immunodeficiency syndrome (AIDS). It is used in combination with other anti-HIV medicines to help control your HIV infection. Your doctor will discuss with you which combination of these medicines with EVOTAZ is best for you.

2. What you need to know before you take EVOTAZ
Do not take EVOTAZ
  • if you are allergic to atazanavir, cobicistat or any of the other ingredients of this medicine (listed in section 6)
  • if you have moderate to severe liver problems
  • if you are taking any of these medicines: see also Other medicines and EVOTAZ
    • rifampicin (an antibiotic used to treat tuberculosis)
    • carbamazepine, phenobarbital and phenytoin (antiepileptics used to prevent seizures)
    • astemizole or terfenadine (commonly used to treat allergy symptoms, these medicines may be available without prescription); cisapride (used to treat gastric reflux, sometimes called heartburn); pimozide (used to treat schizophrenia); amiodarone, dronedarone, quinidine, lidocaine (injectable) or bepridil (used to correct heart rhythm); ergotamine, dihydroergotamine, ergonovine, ergometrine and methylergonovine (used to treat headaches); and alfuzosin (used to treat enlarged prostatic gland)
    • quetiapine (used to treat schizophrenia, bipolar disorder and major depressive disorder); lurasidone (used to treat schizophrenia)
    • medicines containing St. John’s wort (Hypericum perforatum, a herbal preparation).
    • triazolam and oral (taken by mouth) midazolam (used to help you sleep and/or to relieve anxiety)
    • simvastatin, lovastatin, and lomitapide (used to lower blood cholesterol)

Do not take sildenafil with EVOTAZ when sildenafil is used for the treatment of pulmonary arterial hypertension. Sildenafil is also used for the treatment of erectile dysfunction. Tell your doctor if you are using sildenafil for the treatment of erectile dysfunction.

Tell your doctor at once if any of these apply to you.

Warnings and precautions

Some people will need special care before or while taking EVOTAZ. Talk to your doctor or pharmacist before taking EVOTAZ.

EVOTAZ is not a cure for HIV infection. You may continue to develop infections or other illnesses linked to HIV infection.

Make sure your doctor knows:

  • if you have liver problems
  • if you develop signs or symptoms of gall stones (pain in your right side). Gall stones have been reported in patients taking atazanavir, a component of EVOTAZ.
  • if you have type A or B haemophilia. You may notice increased bleeding.
  • if you have problems with your kidneys or require haemodialysis. Kidney stones have been reported in patients taking atazanavir, a component of EVOTAZ. If you develop signs or symptoms of kidney stones (pain in your side, blood in your urine, pain when you urinate), please inform your doctor immediately
  • if you are taking oral contraceptives ("the Pill") to prevent pregnancy. If you are currently using an oral contraceptive or using a patch contraceptive to prevent pregnancy, you should use an additional or different type of contraception (e.g. condom)

In some patients with advanced HIV infection (AIDS) and a history of opportunistic infection, 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, enabling the body to fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please inform your doctor immediately. In addition to the opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.

Some patients taking combination antiretroviral therapy may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). The length of combination antiretroviral therapy, corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index, among others, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are joint stiffness, aches and pains (especially of the hip, knee and shoulder) and difficulty in movement. If you notice any of these symptoms please inform your doctor.

Hyperbilirubinaemia (an increase in the level of bilirubin in the blood) has occurred in patients receiving EVOTAZ. The signs may be a mild yellowing of the skin or eyes. If you notice any of these symptoms please inform your doctor.

Serious skin rash, including Stevens-Johnson syndrome, may develop in patients taking EVOTAZ. If you develop a rash inform your doctor immediately.

EVOTAZ may affect how well your kidneys work.

If you notice a change in the way your heart beats (heart rhythm changes), please inform your doctor.


Do not give this medicine to children under 12 years of age or who weigh less than 35 kg, as the use of EVOTAZ was not studied in this population.

Other medicines and EVOTAZ

It is important to tell your doctor if you are taking: Corticosteroids including dexamethasone betamethasone, budesonide, fluticasone, mometasone, prednisone, triamcinolone. These medicines are used to treat allergies, asthma, inflammatory bowel diseases, inflammatory conditions of the eyes, joints and muscles and other inflammatory conditions. If alternatives cannot be used, its use should only take place after medical evaluation and under close monitoring by your doctor for corticosteroid side effects.

Pregnancy and breast-feeding

EVOTAZ should not be used during pregnancy, because the drug levels in your blood may be lower during pregnancy and may no longer be high enough to control HIV. Your doctor may prescribe different medicines if you become pregnant while taking EVOTAZ.

Atazanavir, a component of EVOTAZ is excreted in human milk. It is unknown if cobicistat, the other component of EVOTAZ, is excreted in human milk but it has been shown in animals that it is excreted in milk. Patients should not breast-feed while taking EVOTAZ.

Breast-feeding is not recommended in women living with HIV because HIV infection can be passed on to the baby in breast milk.

If you are breast-feeding, or thinking about breast-feeding, you should discuss it with your doctor as soon as possible.

Driving and using machines

Some patients have reported dizziness when taking atazanavir or cobicistat, active substances of EVOTAZ. If you feel dizzy or lightheaded, do not drive, use any tools or use machines and contact your doctor immediately.

3. How to take EVOTAZ

Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. This way, you can be sure your medicine is fully effective and you reduce the risk of the HIV-virus developing resistance to the treatment.

The recommended adult and adolescent (aged 12 years and older weighing at least 35 kg) dose of EVOTAZ is one tablet daily by mouth and with food, in combination with other anti-HIV medicines. The tablets have a poor taste, therefore swallow the tablet whole; do not crush or chew the tablets. This will help ensure you get the full dose.

If you take more EVOTAZ than you should

If you accidentally take more EVOTAZ than your doctor recommended, contact your doctor at once or contact the nearest hospital for advice.

If you forget to take EVOTAZ

If you miss a dose of EVOTAZ by 12 hours or less, take it right away with food and then take your next scheduled dose at the usual time. If you miss a dose and it is more than 12 hours from the time you should have taken EVOTAZ, do not take the missed dose. Wait and take the next dose at the usual time. Do not double the next dose. It is important that you do not miss any doses of EVOTAZ or your other anti-HIV medicines.

If you stop taking EVOTAZ

Do not stop taking EVOTAZ before talking to your doctor.

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