About Prezista

Prezista is an oral tablet used for the treatment of HIV (Human Immunodeficiency Virus) infection in adults. HIV is the virus that causes AIDS (Acquired Immune Deficiency Syndrome). Prezista is a type of anti-HIV drug called a protease inhibitor.

Prezista does not cure HIV infection or AIDS. At present, there is no cure for HIV infection. People taking Prezista may still develop infections or other conditions associated with HIV infection. Because of this, it is very important for you to remain under the care of a doctor. Although Prezista is not a cure for HIV or AIDS, Prezista can help reduce your risks of getting illnesses associated with HIV infection (AIDS and opportunistic infection) and eventually dying from these conditions.

Prezista does not reduce the risk of passing HIV to others through sexual contact, sharing needles, or being exposed to your blood.

When used with other anti-HIV medicines, Prezista may reduce the amount of HIV in your blood and increase your CD4 cell count. Reducing the amount of HIV and increasing the CD4 cell count may improve your immune system and, thus, reduce the risk of death or infections that can happen when your immune system is weak.

Side Effects of Prezista

  • Mild to moderate rash has been reported in 7% of subjects receiving Prezista. In some patients, Prezista has been reported to cause a severe or life-threatening rash. Contact your healthcare provider if you develop a rash.
  • High blood sugar (hyperglycemia) and diabetes. This can happen in patients taking Prezista or other protease inhibitor medicines. Some patients have diabetes before starting treatment with Prezista which gets worse. Some patients get diabetes during treatment with Prezista. Some patients will need changes in their diabetes medicine. Some patients may need new diabetes medicine.
  • Increased bleeding in patients with hemophilia. This may happen in patients taking Prezista as it has been reported with other protease inhibitor medicines.
  • Changes in body fat. These changes can happen in patients taking anti-HIV medicines. The changes may include an increased amount of fat in the upper back and neck, breast, and around the back, chest, and stomach area. Loss of fat from the legs, arms, and face may also happen.
  • Immune reconstitution syndrome. In some patients with advanced HIV infection (AIDS) and a history of opportunistic infection, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to an improvement in the body’s immune response, enabling the body to fight infections that may have been present with no obvious symptoms.
  • The most common side effects that may occur with Prezista include: diarrhea, nausea, headache, and common cold.
