Indication

PREZISTA™ is a prescription medication. It is one treatment option in the class of HIV (human immunodeficiency virus) medicines known as protease inhibitors (PI).

PREZISTA™ is always used with 100 mg ritonavir (Norvir^®) in combination with other HIV medicines for the treatment of HIV infection in treatment-experienced adult patients, such as those with HIV resistant to more than one PI.

• The use of other medications active against your HIV in combination with PREZISTA™/ritonavir (Norvir^®) may increase the likelihood of your overall treatment response. Your healthcare professional will work with you to find the right combination of other HIV meds.
• The long-term benefits and side effects of PREZISTA™ therapy are unknown at this time. It is important that you remain under the care of your healthcare professional.

PREZISTA™ is not approved for the treatment of HIV infection in adult patients who have never taken HIV medications before or in pediatric patients.

PREZISTA™ does not cure HIV infection or AIDS, and does not prevent passing HIV to others.
