SUSTIVA may not have these effects in every patient. SUSTIVA does not cure HIV or AIDS. You must keep taking HIV medicines in order to help control HIV infection and decrease HIV-related illnesses.

WHO SHOULD NOT TAKE SUSTIVA?

 

Do not take SUSTIVA if you are allergic to the active ingredient, efavirenz, or to any of the inactive ingredients. Your doctor and pharmacist have a list of the inactive ingredients.

MEDICAL TERMS TO KNOW

 

Viral load is a measure of the amount of HIV in your blood. It is usually measured in copies of HIV per 1 milliliter (mL) of blood. It may be used to judge how well your treatment is working.

A CD4+ cell is a type of white blood cell that fights infection and can be attacked by HIV. It may also be called a T-cell. It is usually measured in number of CD4+ T cells per one microliter (mm3) of blood and can tell you about the strength of your immune system.
