Reyataz

1 What is Reyataz?

Brand: Reyataz

Generic: Atazanavir

Reyataz is an antiretroviral drug that is used to treat infection caused by the human immunodeficiency virus.

This medicine does not cure HIV infection or AIDS. It interferes with the reproduction of HIV to slow down the destruction of the immune system. This will help to reduce your risk to develop complications associated with HIV infection.

Even though you are taking Atazanavir, this will not keep you from transmitting HIV to other people. People who receive this medicine may continue to have other problems usually related to AIDS or HIV disease.

This product is available in capsule and powder form.

2 What to Know Before Using

Before using Reyataz, you must know all about the risks and complications associated with it. Tell your doctor if you are allergic to Reyataz or to any other medications. This medicine is not recommended in infants younger than 3 months of age.

Although this medicine has not demonstrated geriatric-specific problems, older patients are more likely to have age-related liver, kidney, or heart problems, which may require caution in patients receiving Reyataz.

There are no adequate studies whether atazanavir can pass through breast milk or if it could cause harmful effects to the infant. Discuss with your doctor if you are breastfeeding a baby. Taking this medication with any of the following medicines is not recommended.
