REYATAZ is a prescription medicine used to treat HIV-1 (Human Immunodeficiency Virus type 1) infection in adults, and in children who are 3 months of age and older and weigh at least 11 pounds (5 kg). A complete treatment regimen of REYATAZ in combination with other antiretroviral medicines is important to properly treat HIV.

REYATAZ will not cure HIV infection or AIDS (Acquired Immunodeficiency Syndrome), but, when taken properly, it can help reduce the amount of HIV-1 and increase the amount of infection-fighting immune cells in your blood:

• You must stay on continuous HIV-1 therapy in order to control your HIV-1 infection, decrease HIV-1-related illness, and reduce the chance of viral resistance.
• Do not give REYATAZ to children younger than 3 months of age.

REYATAZ helps prevent cells infected by HIV from producing more HIV. This reduces the amount of the virus in your body. REYATAZ as part of combination therapy is one of several treatment options your doctor may consider. REYATAZ does not cure HIV-1 infection or AIDS (Acquired Immunodeficiency Syndrome). You must keep taking HIV-1 medicines to control HIV-1 infection and decrease HIV-related illnesses.

HIV is a virus that multiplies quickly. Untreated, it can produce billions of copies of itself every day. But HIV cannot multiply on its own. It uses the CD4+ cells of your immune system. Normally, CD4+ cells fight bacteria and viruses to keep you healthy. As HIV multiplies, it destroys CD4+ cells.

REYATAZ is in the category of HIV drugs known as protease inhibitors (PIs). PIs prevent HIV from copying itself effectively.

REYATAZ can help raise your CD4+ cells and lower your viral load to undetectable.*

Do not take REYATAZ if you are:

• Allergic to REYATAZ or to any of its ingredients
• Taking certain medicines with REYATAZ that may affect how REYATAZ works. REYATAZ may cause serious or life-threatening side effects, or death if taken with the following medicines:
  • alfuzosin
  • amiodarone (when REYATAZ is used with ritonavir)
  • cisapride
  • elbasvir and grazoprevir
  • ergot medicines including:
    • dihydroergotamine
    • ergonovine
    • ergonovine ergotamine
    • methylergonovine
  • glecaprevir and pibrentasvir
  • indinavir
  • irinotecan

No. REYATAZ does not cure HIV-1 infection or AIDS (Acquired Immunodeficiency Syndrome). You must keep taking HIV-1 medicines to control HIV-1 infection and decrease HIV-related illnesses (opportunistic infections).

Some of these conditions are pneumonia, herpes virus infections, and Mycobacterium avium complex (MAC) infections. It is very important that you see your healthcare provider regularly while taking REYATAZ.

REYATAZ does not lower your chance of passing HIV to other people through sexual contact, sharing needles, or being exposed to your blood. For your health and the health of others, it is important to always practice safer sex by using a latex or polyurethane condom to lower the chance of sexual contact with semen, vaginal secretions, or blood. Never use or share dirty needles.

The following list of side effects is not complete. Report any new or continuing symptoms to your healthcare provider. If you have questions about side effects, ask your healthcare provider. Your healthcare provider may be able to help you manage these side effects.

REYATAZ can cause serious side effects. Call your healthcare provider right away if you have any of the following:

• A change in the way your heart beats. You may feel dizzy or lightheaded. These could be symptoms of a heart problem.
• Skin rash is common with REYATAZ but can sometimes be severe and may develop with other symptoms which can be serious. If you develop a severe rash or a rash with any of the following symptoms, stop taking REYATAZ and call your healthcare provider or go to the nearest hospital emergency room right away: general feeling of discomfort or “flu-like” symptoms, fever, muscle or joint aches, red or inflamed eyes, blisters, mouth sores, swelling of your face, painful, warm or red lump under the skin.
• Liver problems including hepatitis B or C may get worse when taking REYATAZ. Your healthcare provider will do blood tests before and during treatment with REYATAZ. Liver problem symptoms may include: dark “tea-colored” urine, your skin or the white part of your eyes turning yellow, light colored stools, nausea, itching, or stomach area pain.
• Chronic kidney disease. REYATAZ may affect how well your kidneys work. Your healthcare provider will do blood and urine tests to check your kidneys before you start REYATAZ and during treatment. Drink plenty of fluids during treatment with REYATAZ.
• Kidney stones have happened in some people taking REYATAZ and sometimes may lead to hospitalization. Symptoms may include pain in your low back or low stomach-area, blood in your urine, pain when you urinate.
• Gallbladder stones have happened in some people who take REYATAZ, and sometimes may lead to hospitalization. Symptoms may include pain in the right or middle upper stomach area, fever, nausea and vomiting, or your skin or the white part of your eyes turning yellow.
• Yellowing of your skin or the white part of your eyes is common, and usually not harmful in adults and infants older than 3 months of age, but it could also be a symptom of a serious problem. This may occur due to increases in bilirubin levels in the blood (bilirubin is made by the liver).
• New or worsening diabetes and high blood sugar have happened in some people who take protease inhibitor medicines like REYATAZ. Some people may need to start diabetes medicine or change their dose of their diabetes medicine.
• Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV-1 medicines. Tell your healthcare provider if you have any new symptoms after starting REYATAZ.
• Changes in body fat can happen in people taking HIV-1 medicines. The exact cause and long-term health effects are not known.
• Increased bleeding problems in people with hemophilia have happened when taking protease inhibitors like REYATAZ.
• The most common side effects of REYATAZ include: nausea, headache, stomach-area pain, vomiting, trouble sleeping, numbness, tingling, or burning of hands or feet, dizziness, muscle pain, diarrhea, depression, and fever.
• If you experience any side effects while on REYATAZ, talk to your healthcare provider right away.

REYATAZ use during pregnancy has not been associated with an increase in birth defects. Pregnant women have experienced serious side effects when taking REYATAZ with other HIV medicines called nucleoside analogues. You and your healthcare provider will need to decide if REYATAZ is right for you. If you use REYATAZ while you are pregnant, talk to your healthcare provider about the Antiretroviral Pregnancy Registry. And after your baby is born, tell your healthcare provider if your baby's skin or the white part of his/her eyes turns yellow.

Do not breastfeed. REYATAZ can be passed to your baby in your breast milk and it is not known whether it could harm your baby. Also, mothers with HIV-1 should not breastfeed because HIV-1 can be passed to the baby in the breast milk.

Over time, HIV can become resistant to HIV drugs. When patients develop resistance to a drug in a certain class (for example, REYATAZ, which is a protease inhibitor [PI]), they often become resistant to many or all of the drugs in that class.
