Read this Patient Information before you start taking ISENTRESS and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment.
What is ISENTRESS?
ISENTRESS is a prescription HIV medicine used with other antiretroviral medicines to treat Human Immunodeficiency Virus-1 (HIV-1) infection in people 4 weeks of age and older. HIV is the virus that causes AIDS (Acquired Immune Deficiency Syndrome).
It is not known if ISENTRESS is safe and effective in babies under 4 weeks of age.
When used with other HIV medicines to treat HIV-1 infection, ISENTRESS may help:
- reduce the amount of HIV in your blood. This is called “viral load”.
- increase the number of white blood cells called CD4+ (T) cells in your blood, which help fight off other infections.
- reduce the amount of HIV-1 and increase the CD4+ (T) cells in your blood, which may help improve your immune system. This may reduce your risk of death or getting infections that can happen when your immune system is weak (opportunistic infections).
ISENTRESS does not cure HIV-1 infection or AIDS.
You must stay on continuous HIV therapy to control HIV-1 infection and decrease HIV-related illnesses.
Avoid doing things that can spread HIV-1 infection to others.
- Do not share or re-use needles or other injection equipment.
- Do not share personal items that can have blood or body fluids on them, like toothbrushes and razor blades.
- Do not have any kind of sex without protection. Always practice safe sex by using a latex or polyurethane condom to lower the chance of sexual contact with any body fluids such as semen, vaginal secretions, or blood.
- Ask your doctor if you have any questions on how to prevent passing HIV to other people.
