What ATAZANAVIR MYL is used for

ATAZANAVIR MYL is used in combination with other anti-HIV agents to treat adults and

What is HIV
HIV is a virus that kills important cells in the immune system over time (e.g. CD4
cells). When HIV has killed enough of the immune cells, your body becomes prone to
certain types of infections. Some infections are the cause of "AIDS-defining" illnesses.
This is when someone is said to have developed Acquired Immunodeficiency Syndrome
or AIDS. AIDS is a serious condition and can lead to death.
How ATAZANAVIR MYL works
When HIV infects cells in the immune system, it takes over part of the cell's internal
workings and uses the contents of the cell to produce new viruses.
ATAZANAVIR MYL helps to block HIV protease, an enzyme that is needed for the HIV virus
to multiply. ATAZANAVIR MYL may lower the amount of HIV in your blood and help your
body keep its supply of CD4 and T-cells. Interfering with the production of new viruses
helps to reduce the total amount of HIV in the body and slows down the damage to the
ATAZANAVIR MYL is not a cure for HIV infection. Taking it will not necessarily prevent
the illnesses that commonly occur in people with HIV infection or AIDS. You can still
infect other people with HIV while you are taking this medicine.
Ask your doctor if you have any questions about why this medicine has been prescribed
ATAZANAVIR MYL is not addictive.

Yellowing of the skin or eyes
One of the other side effects that can occur with ATAZANAVIR MYL is yellowing of the

by an increase in a substance called bilirubin. Bilirubin is formed naturally by the
breakdown of red blood cells and is usually excreted by the liver.

is unlikely that these effects will cause damage to your skin, eyes or liver, it is
important that you tell your doctor promptly if they occur.

allergic reaction - swelling of the face, lips, or throat which makes breathing difficult
