Evotaz – Cobicistat / Atazanavir uses, dose and side effects


300 mg / 150 mg film-coated tablets 
atazanavir / cobicistat

1. What EVOTAZ is and what it is used for

EVOTAZ contains two active substances:

  • atazanavir, an antiviral (or antiretroviral) medicine. It belongs to a group called protease inhibitors. This drug controls the Human Immunodeficiency Virus ( HIV ) – infection, by stopping the production of a protein that HIV – the virus et needs to multiply. It works by reducing the number of HIV – the virus in the blood and this, in turn, strengthens your immune system. This reduces EVOTAZ’s risk of diseases associated with HIV, which will be developed.
  • cobicistat, an enhancer ( pharmacokinetic enhancer) that helps to improve the effects of atazanavir. Cobicistat, do not treat your HIV – infection, but enhances the levels of atazanavir in the blood, by atazanavir is broken down more slowly and therefore stays in the body longer.

EVOTAZ can be used by adults over 18 who are infected with HIV – the virus that can cause 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 combinations of these medicines together with EVOTAZ are best for you.

Warnings and cautions

For some people, special consideration may need to be given before or when taking EVOTAZ. Talk to your doctor or pharmacist before taking EVOTAZ.

EVOTAZ is not a cure for HIV – infection. You can continue to develop infections or diseases associated with HIV. You can still transmit HIV to other people when you take this medicine, even though the risk of effective antiviral treatment is reduced. Discuss with your doctor the necessary steps to avoid infecting others.

Make sure your doctor knows the following:

  • if you have liver problems
  • if you develop signs or symptoms of gallstones (pain in the right side). Gallstones have been reported in patients taking atazanavir, one of the substances in EVOTAZ.

  • if you have kidney problems or need hemodialysis. Kidney stones have been reported in patients taking atazanavir, a substance in EVOTAZ. Tell your doctor immediately if you develop signs and symptoms of kidney stones (pain in the side, blood in the urine, pain when urinating).

In some patients with advanced HIV – infection ( AIDS ) and a history of opportunistic infection, you ( the infection that occurs due to the immune system is impaired), signs and symptoms of inflammation from previous infections may occur soon after anti- HIV started. These symptoms are probably due to an improvement in the body’s immune response, which enables the body to fight infections that may have been present without any obvious symptoms. Tell your doctor immediately if you notice any symptoms of infection. In addition to opportunistic infection, you can autoimmune disorders (a condition in which the immune system attacks healthy body tissue) may also occur after you start taking medicines to treat your HIV – infection. Autoimmune disorders can occur several months after starting treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, a weakness that starts in the hands or feet and moves to the torso, palpitations, tremors, or hyperactivity, inform your doctor immediately for the necessary treatment.

Some patients receiving combination antiretroviral therapy may develop a bone disease called osteonecrosis (bone tissue dies due to lost blood supply to the bone). Some of the many risk factors for developing the disease are long-term antiretroviral combination therapy, use of corticosteroids, alcohol consumption, a severe weakening of the immune system, and higher body mass index. Signs of osteonecrosis are stiffness in the joints and pain (especially in the hip, knee, and shoulders) and difficulty moving. Tell your doctor if you experience any of these symptoms.
