Full Consumer Medicine Information (CMI)

This leaflet provides important information about using REYATAZ. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using REYATAZ.
Where to find information in this leaflet:

1. Why am I using REYATAZ?

REYATAZ contains the active ingredient 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.
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.

2. What should I know before I use REYATAZ?

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.
2) If you 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

Your doctor may monitor your kidney function prior to, and during your treatment with REYATAZ. Your doctor may switch you to an alternative treatment if your kidney function changes.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you 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.
Talk to your doctor if you are breastfeeding or intend to breastfeed.
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).

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.
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:
Medicines to treat hepatitis (e.g. telaprevir, bocepravir, sofosbuvir/velpatasvir/voxilaprevir)
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.
Macrolide antibiotics (clarithromycin, roxithromycin, erythromycin, or azithromycin) used to treat various infections
Antifungal medication (voriconazole) used to treat fungal infections
Anticonvulsant medication (lamotrigine) used to treat epilepsy
Erectile dysfunction agents used to treat impotence - sildenafil, tadalafil, vardenafil.
Amiodarone, bepridil, lignocaine, quinidine, or tricyclic antidepressants - if you take any of these medicines, your doctor may ask you to have blood tests just to make sure that REYATAZ and the other medicine are not affecting the way each medicine works.
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.

4. How do I use REYATAZ?

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 OR REYATAZ 300 mg once daily 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 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.
Follow the instructions provided and use REYATAZ until your doctor tells you to stop.

How to take REYATAZ

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 REYATAZ

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 REYATAZ

If it is almost time for your next dose, skip the dose you missed and take your 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 REYATAZ

If you think that you have used too much REYATAZ, you may need urgent medical attention.
You should immediately:
phone the Poisons Information Centre
(by calling 13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.

Things you should do

Make sure that you visit your doctor regularly throughout your entire course of treatment with REYATAZ.
