What REYATAZ is and What it is used for
REYATAZ is an antiviral (or antiretroviral) medicine. It is one of a group called protease inhibitors. These medicines control Human Immunodeficiency Virus (HIV) infection by stopping a protein that the HIV needs for its multiplication. They work by reducing the amount of HIV in your body and this in turn, strengthens your immune system. In this way REYATAZ reduces the risk of developing illnesses linked to HIV infection.
REYATAZ capsules may be used by adults and children 6 years of age and older. Your doctor has prescribed REYATAZ for you because you are infected by the HIV that causes Acquired Immunodeficiency Syndrome (AIDS). It is normally used in combination with other anti-HIV medicines. Your doctor will discuss with you which combination of these medicines with REYATAZ is best for you.

Warnings and precautions
REYATAZ is not a cure for HIV infection. You may continue to develop infections or other illnesses linked to HIV infection. You can still pass on HIV when taking this medicine, although the risk is lowered by effective antiretroviral therapy. Discuss with your doctor the precautions needed to avoid infecting other people.
Some people will need special care before or while taking REYATAZ. Talk to your doctor or pharmacist before taking REYATAZ and make sure your doctor knows:
if you have hepatitis B or C
if you develop signs or symptoms of gall stones (pain at the right side of your stomach)
if you have type A or B haemophilia
if you require haemodialysis
REYATAZ may affect how well your kidneys work.
Kidney stones have been reported in patients taking REYATAZ. If you develop signs or symptoms of kidney stones (pain in your side, blood in your urine, pain when you urinate), please inform your doctor immediately.
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. If you notice any symptoms of infection, please inform your doctor immediately. In addition to the opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.
Some patients taking combination antiretroviral therapy may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). The length of combination antiretroviral therapy, corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index, among others, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are joint stiffness, aches and pains (especially of the hip, knee and shoulder) and difficulty in movement. If you notice any of these symptoms please inform your doctor.
Hyperbilirubinaemia (an increase in the level of bilirubin in the blood) has occurred in patients receiving REYATAZ. The signs may be a mild yellowing of the skin or eyes. If you notice any of these symptoms please inform your doctor.
Serious skin rash, including Stevens-Johnson syndrome, has been reported in patients taking REYATAZ. If you develop a rash inform your doctor immediately.
If you notice a change in the way your heart beats (heart rhythm changes), please inform your doctor. Children receiving REYATAZ may require their heart to be monitored. Your child's doctor will decide this.
Children
Do not give this medicine to children younger than 3 months of age and weighing less than 5 kg. The use of REYATAZ in children less than 3 months of age and weighing less than 5 kg has not been studied due to the risk of serious complications.

Atazanavir, the active substance of REYATAZ, is excreted in human milk. Patients should not breast-feed while taking REYATAZ. It is recommended that women infected with HIV do not breast-feed because the virus might be transmitted through the breast milk.

If you have been told by your doctor that you have an intolerance to some sugars (e.g. lactose), contact your doctor before taking this medicinal product.

For children (6 to less than 18 years of age), your child's doctor will decide the right dose based on your child's weight. The dose of REYATAZ capsules for children is calculated by body weight and is taken once daily with food and 100 mg ritonavir as shown below:
Body Weight (kg) | REYATAZ Dose once daily (mg) | Ritonavir Dose* once daily (mg) |
15 to less than 35 | 200 | 100 |
at least 35 | 300 | 100 |
*Ritonavir capsules, tablets or oral solution may be used. | ||
REYATAZ is also available as an oral powder for use in children at least 3 months old and weighing
at least 5 kg. Switching to REYATAZ capsules from REYATAZ oral powder is encouraged as soon as patients are able to consistently swallow capsules.
A change in dose may occur when switching between oral powder and capsules. Your doctor will decide the right dose based on your child’s weight.
There are no dosing recommendations for REYATAZ in paediatric patients less than 3 months of age.

If you accidentally take more REYATAZ capsules than your doctor recommended, contact your HIV
doctor at once or contact the nearest hospital for advice.
If you forget to take REYATAZ
If you miss a dose, take the missed dose as soon as possible with food and then take your next scheduled dose at its regular time.

Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them. When treating HIV infection, it is not always easy to identify what side effects are caused by REYATAZ, by the other medicines you are taking, or by the HIV infection itself. Tell your doctor if you notice anything unusual about your health.
During HIV therapy there may be an increase in weight and in levels of blood lipids and glucose. This is partly linked to restored health and life style, and in the case of blood lipids sometimes to the HIV medicines themselves. Your doctor will test for these changes.
Tell your doctor immediately if you develop any of the following serious side effects:
Skin rash, itching that may occasionally be severe has been reported. The rash usually disappears within 2 weeks without any change to your REYATAZ treatment. Severe rash may be developed in association with other symptoms which could be serious. Stop taking REYATAZ and talk to your doctor immediately if you develop a severe rash or a rash with flu-like illness symptoms, blisters, fever, mouth sores, muscle or joint pain, swelling in the face, inflammation of the eye which causes redness (conjunctivitis), painful, warm, or red lumps (nodules).
Yellowing of your skin or the white part of your eyes caused by high levels of bilirubin in your
blood has been commonly reported. This side effect is usually not dangerous in adults and infants older than 3 months of age; but it might be a symptom of a serious problem. If your skin or the white part of your eyes turns yellow, talk to your doctor immediately.
Changes in the way your heart beats (heart rhythm change) may occasionally happen. Talk to your doctor immediately if you get dizzy, lightheaded or if you suddenly faint. These could be symptoms of a serious heart problem.
Liver problems may uncommonly happen. Your doctor should do blood tests prior you start REYATAZ and during treatment. If you have liver problems, including hepatitis B or C infection, you may experience a worsening of your liver problems. Talk to your doctor immediately if you get dark (tea-colored) urine, itching, yellowing of your skin or the white part of your eyes, pain around the stomach, pale colored stools or nausea.
Gallbladder problems uncommonly happen in people taking REYATAZ. Symptoms of
gallbladder problems may include pain in the right or middle upper stomach area, nausea, vomiting, fever or yellowing your skin or the white part of your eyes.
