How does Evotaz work? What will it do for me?

This combination product contains two medications: atazanavir and cobicistat. These two medications are used in combination with other medications to reduce the amount of human immunodeficiency virus (HIV) in the blood.

Atazanavir is a protease inhibitor and works by blocking an enzyme called protease, which the virus needs to multiply. Cobicistat slows down the speed at which the body gets rid of atazanavir. It is included in this medication to increase the length of time that the body is exposed to atazanavir with each dose.

This medication does not cure AIDS and does not reduce the risk of passing HIV to others through sexual contact or blood contamination. It is used in combination with other anti-HIV medications to slow further growth or reproduction of HIV. It also seems to slow down the destruction of the immune system. This may help to delay the development of problems such as infections related to AIDS or HIV disease.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

What form(s) does Evotaz come in?

Each oval, biconvex, pink, film-coated tablet debossed with “3641” on one side and plain on the other contains 300 mg of atazanavir (as atazanavir sulfate) and 150 mg of cobicistat.

Are there any other precautions or warnings for Evotaz?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Diabetes: Atazanavir – cobicistat may cause a loss of blood glucose control, and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication.

If you have diabetes or are at risk for developing diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Fat redistribution: Over time, this medication may change how fat is distributed in your body and may change your body shape. You may notice increased fat in the upper back and neck, breast, around the back, chest, and stomach area; or loss of fat from the legs, arms, and face. The long-term effects of this are not known.

Heart rhythm: Atazanavir – cobicistat can cause changes to the normal rhythm of the heart, which can cause fainting, seizures and, in severe cases, sudden death. If you are at risk for heart rhythm problems (e.g., if you have heart failure, angina, or low potassium or magnesium levels), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Hemophilia: People with hemophilia type A and B, which are blood-clotting disorders, have experienced increased bleeding and bruising when taking protease inhibitors such as atazanavir. If you have hemophilia, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Immune reconstitution syndrome: This medication may cause immune reconstitution syndrome, where signs and symptoms of inflammation from previous infections appear. These symptoms occur soon after starting anti-HIV medication and can vary. They are thought to occur as a result of the immune system improving and being able to fight infections that have been present without symptoms (such as pneumonia, herpes or tuberculosis). Report any new symptoms to your doctor immediately.

Kidney function: This medication has been reported to cause changes in kidney function. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication. People with severe liver disease should not take atazanavir – cobicistat.

There have been reports of serious liver problems while taking atazanavir. People with liver problems (including hepatitis B or hepatitis C infection) are at a greater risk of experiencing serious liver problems while taking this medication. If you experience symptoms of liver problems (e.g., abdominal pain, persistent vomiting, feeling unwell, fever, itching, yellowing of the skin and eyes, dark urine), contact your doctor immediately.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: It is not known if atazanavir – cobicistat passes into breast milk. Women who have HIV infection are cautioned against breast-feeding because of the risk of passing HIV to a baby who does not have the infection.

Children: The safety and effectiveness of using this medication have not been established for children.
