What REYATAZ is used for
Reyataz is a trade name (manufacturer's name) for the medicine, atazanavir. Reyataz belongs to a group of medicines called protease inhibitors.
Reyataz is used in combination with other anti-HIV agents to treat adults and children aged between 6 and 18 years of age who are infected with Human Immunodeficiency Virus (HIV).
What is HIV:
HIV is a virus that kills important cells in the immune system over time (e.g. CD4 cells). When HIV has killed enough of the immune cells, your body becomes prone to certain types of infections. Some infections are the cause of "AIDS-defining" illnesses. This is when someone is said to have developed the Acquired Immunodeficiency Syndrome or AIDS. AIDS is a serious condition and can lead to death.
How REYATAZ Works
When HIV infects cells in the immune system, it takes over part of the cell's internal workings and uses contents of the cells to produce new viruses.
Reyataz helps to block HIV protease, an enzyme that is needed for the HIV virus to multiply. Reyataz may lower the amount of HIV in your blood and help your body keep its supply of CD4 and T-cells. Interfering with the production of new viruses helps to reduce the total amount of HIV in the body and slows down the damage to the immune system.
Reyataz is not a cure for HIV infection. Taking it will not necessarily prevent the illnesses that commonly occur in people with HIV infection or AIDS. You can still infect other people with HIV while you are taking this medicine.
Ask your doctor if you have any questions about why Reyataz has been prescribed for you.
Reyataz is not addictive. This medicine is available only with a doctor's prescription.

Before you start to take REYATAZ
Tell your doctor if you:
- have allergies to:
- other medicines that are called 'protease inhibitor'
- any other medicines you have been given or purchased
- substances such as foods, preservatives or dyes.
Symptoms of an allergic reaction may include:
swelling of the face, lips, tongue or throat which may cause difficulty in swallowing or breathing, or severe and sudden onset of pinkish, itchy swellings on the skin, also called hives.
- are pregnant or intend to become pregnant. Experience is limited with the use of Reyataz in pregnant women. Therefore, it should not be used during pregnancy unless it is clearly needed. If there is an urgent need to consider Reyataz during pregnancy, your doctor will discuss with you the benefits and risks of taking it.
- are breast feeding or planning to breast-feed. It is not known whether Reyataz passes into breast milk. Therefore to avoid possible side effects in the nursing infant, mothers should stop breast-feeding if they are taking Reyataz (breast-feeding can also transfer HIV to babies).
- currently experience or have experienced any medical conditions especially:
- liver problems including hepatitis, yellowing of the skin or eyes (jaundice) or prior use of medicines toxic to the liver. Liver problems may cause higher levels of Reyataz in the blood, increasing the chance of side effects
- haemophilia, haemophiliac patients may experience increased bleeding when taking Reyataz
- any problems with irregular heart beat
- diabetes or impaired glucose tolerance
If you have not told your doctor about any of the above, tell them before you use Reyataz.
Taking other medicines
Reyataz has the potential to adversely interact with many other drugs.
Be sure to inform your doctor of all medications you are taking including prescribed drugs, over the counter products, natural therapies, vitamin supplements and recreational drugs.
Medicines for HIV:
Reyataz will be given with other anti-HIV medicines, some of these anti-HIV medicines may affect the way Reyataz works, and Reyataz may affect the way some other anti-HIV medicines work. Your doctor has all the current information on the effects these medicines have on one another and will discuss with you the combination of medicines that you should be taking.
Medicines for other conditions:
You should also tell your doctor if you are taking any of the following medicines:
- Proton-pump inhibitors or histamine-2 receptor antagonists (medicines used to treat stomach ulcers or other stomach disorders). If you plan to take or are currently taking either histamine-2 receptor antagonists (such as cimetidine, famotidine, ranitidine or other medicines in this class) or proton-pump inhibitors (such as omeprazole or others in this class of medicine), then you must speak to your doctor as these may reduce the effectiveness of Reyataz. Depending on your medical history these medicines may not be suitable for you. Talk to your doctor for further information.

- Calcium channel blockers (such as diltiazem, felodipine, nifedipine, nicardipine or verapamil) - medicines used to treat high blood pressure
- Antacids and buffered medicines reduce the absorption of Reyataz. These medicines should be taken one hour before or two hours after Reyataz.

How to take REYATAZ
Reyataz should be given only when prescribed by your doctor. Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
How much to take
If you are new to HIV treatment, your doctor may prescribe Reyataz 400 mg (2 x 200 mg capsules) once a day with food.
Reyataz 300 mg once daily (either as one 300 mg capsule or two 150 mg capsules) with ritonavir (100 mg daily) taken with food.
If you have been on previous HIV treatment, the usual dose is Reyataz 300 mg once daily (either as one 300 mg capsule or two 150 mg capsules) with ritonavir (100 mg daily) taken with food.
You doctor will tell you what dose of Reyataz you should take.
If you are between the ages of 6 and 18 years old, the dose of Reyataz will be different. Please follow your doctor's instructions.
How to take it
Swallow the capsules whole with a drink such as a glass of water or fruit juice. The dose of Reyataz should be taken with food.
When to take REYATAZ
You may take Reyataz Capsules at any time. It is recommended, however, that you take your medicine at about the same time each day. Taking Reyataz at the same time each day will have the best effect. It will also help you remember when to take the capsules.
Talk to your doctor or pharmacist to work out when it is best for you to take your doses of Reyataz.
How long to take it
Reyataz helps control your condition but does not cure it. Therefore you must take Reyataz every day as directed by your doctor. Continue taking Reyataz for as long as your doctor tells you to.
Do not stop taking Reyataz unless your doctor tells you to - even if you feel better.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to take it.
Otherwise take it as soon as you remember, and then go back to taking it as you would normally.
Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect. If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints and inform your doctor that you have missed a dose. It is very important not to miss your doses of Reyataz. If you miss doses the virus may become resistant to your HIV medicines.
If you take too much (overdose)
Immediately call your doctor or the Poisons Information Centre on 13 11 26 in Australia, or go to the Accident and Emergency Centre at your nearest hospital if you or anyone else takes too much Reyataz. Do this even if there are no signs of discomfort or poisoning.
While you are using REYATAZ
Things you must do

- If you are about to start taking any new medicines, tell your doctor and pharmacist that you are taking Reyataz. Reyataz may interfere with the medicine you are taking.
- If you are about to have any medical tests, tell your doctor that you are taking Reyataz. Reyataz may interfere with the results of these tests.
- If you plan to have surgery, tell your doctor or dentist that you are taking Reyataz. You may wish to discuss disclosure issues with your doctor about who should know you are taking Reyataz.
- You should have your liver functions and blood tested when your doctor advises on a regular basis to ensure that your body chemistry is functioning normally and that Reyataz is working.
Things you must not do

Things to be careful of
- Be careful driving or operating machinery until you know how Reyataz affects you. Some patients taking Reyataz have experienced dizziness. It is not known if this was caused by Reyataz. Make sure you know how you react to Reyataz before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy.
- Make sure that you visit your doctor regularly throughout your entire course of treatment with Reyataz.
Things that may help your condition
Things that may help your general health are suggested below:
- healthy eating
- stress reduction
- regular visits to your doctor to monitor your health
- good oral hygiene
- support groups
Talk with your doctor about all of the above suggestions. You can also access further information about HIV and services for people with HIV by contacting your local AIDS Council, Positive Living Centre or PLWHA organisation.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Reyataz. Reyataz helps most people with HIV infection but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- nausea, diarrhoea, dyspepsia (upset stomach), flatulence (wind)
- headache, fatigue, dizziness, insomnia
- loss of strength and energy
These are some of the more common side effects of Reyataz.
Tell your doctor or pharmacist immediately if you notice any of the following
- tingling of the hands or feet
- abdominal pain, abdominal distension or tenderness, vomiting
- changes to the distribution of fat on your body
- pain in the joints, muscle pain
- ulcers in the mouth, oesophagus (pain or burning on swallowing) or stomach (pain or indigestion)
- change in heart rhythm, fainting
These are serious side effects. You may need urgent medical attention or hospitalization.
Yellowing of the skin or eyes
One of the other side effects that can occur with Reyataz is yellowing of the skin (jaundice) or eyes (scleral icterus). Yellowing of the skin or eyes is caused by an increase in a substance called bilirubin. Bilirubin is formed naturally by the breakdown of red blood cells and is usually excreted by the liver.
Call your doctor if your skin or the whites of your eyes turn yellow. Although it is unlikely that these effects will cause damage to your skin, eyes or liver, It is important that you tell your doctor promptly if they occur.
Gallbladder disorders (which may include gallstones and gallbladder inflammation)
If you develop any signs or symptoms of gallstones (pain in the right or middle upper stomach, fever, nausea or vomiting, or yellowing of skin and whites of eyes), tell your doctor promptly.
If you develop signs or symptoms of kidney stones (pain in your side, blood in your urine, pain when you urinate) tell your doctor promptly.
If any of the following happen, tell your doctor immediately, or go to the Accident and Emergency Centre at your nearest hospital:
- liver problems including yellowing of the skin or eyes, also called jaundice; this may occur with vomiting, fever and dark coloured urine
- lactic acidosis - symptoms include nausea, vomiting, unusual or unexpected stomach discomfort, feeling very weak and tired, short of breath, or weakness in arms and legs
- allergic reaction - swelling of the face, lips, or throat which makes breathing difficult
These are very serious side effects. If you have them, you may have had a serious reaction to Reyataz. You may need urgent medical attention or hospitalisation.
This is not a complete list of side effects, other side effects not listed above may also occur in some patients.
Tell your doctor if you notice anything that is making you feel unwell.
Do not be alarmed by this list of possible side effects. You may not experience any of them or only some of them.
After using REYATAZ
Store Reyataz capsules in a cool dry place where the temperature stays below 25°C.
Keep your capsules in the bottle until it is time to take them. If you take the capsules out of the bottle they may not keep as well.
Do not store Reyataz or any other medicine in the bathroom or near the kitchen sink. Do not leave it in the car. Heat and dampness can destroy some medicines.
Keep Reyataz capsules where children cannot reach them. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
