300 mg tenofovir disoproxil fumarate
Consumer Medicine Information
Read this leaflet carefully before you start taking VIREAD. Also, read it each time you get your VIREAD prescription refilled, in case something has changed.
This information does not take the place of talking with your doctor or pharmacist when you start this medicine and at check-ups. You should stay under a doctor’s care when taking VIREAD.
It is extremely important that you do not change or stop your medicine without first talking with your doctor or pharmacist (see HOW SHOULD I TAKE VIREAD and WHAT ARE THE POSSIBLE SIDE EFFECTS OF VIREAD).
Talk to your doctor or pharmacist if you have any questions about VIREAD.
VIREAD is an antiviral medication used to treat two different viruses; Chronic Hepatitis B (CHB) and Human Immunodeficiency Virus (HIV) infection.
VIREAD is a type of medicine called a HBV polymerase inhibitor and a nucleotide analog reverse transcriptase inhibitor (NRTI).
VIREAD is used to treat CHB (an infection with hepatitis B virus [HBV]) in adults and paediatric patients aged 12 years and older and weighing at least 35 kg.
VIREAD works by interfering with the normal working of enzymes (HBV DNA polymerase) that are essential for HBV to reproduce itself. VIREAD may help lower the amount of hepatitis B virus in your body by lowering the ability of the virus to multiply and infect new liver cells and can improve the inflammation and scar tissue caused by the hepatitis B virus in your liver. Lowering the amount of virus in your body may reduce the chance of developing cirrhosis, liver failure and liver cancer.
We do not know how long VIREAD may help treat your hepatitis. Sometimes viruses change in your body and medicines no longer work. This is called drug resistance.
VIREAD is also used to treat HIV infection in adults and paediatric patients aged 12 years and older and weighing at least 35 kg. VIREAD is always used in combination with other anti-HIV medicines to treat people with HIV-1 infection.
HIV infection destroys CD4 (T) cells, which are important to the immune system. After a large number of T cells are destroyed, acquired immune deficiency syndrome (AIDS) develops.
VIREAD helps to block HIV-1 reverse transcriptase, a chemical (enzyme) in your body that is needed for HIV-1 to multiply. VIREAD lowers the amount of HIV 1 in the blood (called viral load) and may help to increase the number of T cells (called CD4 cells). Lowering the amount of HIV-1 in the blood lowers the chance of death or infections that happen when your immune system is weak (opportunistic infections).
You do not have to have HIV-infection to be treated with VIREAD for HBV and vice versa.
VIREAD is for adults and paediatric patients aged 12 years and older and weighing at least 35 kg.
VIREAD does not cure HIV infection or AIDS.
The long-term effects of VIREAD are not known at this time. People taking VIREAD may still get opportunistic infections or other conditions that happen with HIV-1 infection. Opportunistic infections are infections that develop because the immune system is weak. Some of these conditions are:
VIREAD does not reduce the risk of passing HIV-1 or HBV to others through sexual contact or blood contamination.
Continue to practice safe sex and do not use or share dirty needles.
Together with your doctor, you need to decide whether VIREAD is right for you.
Do not take VIREAD if you are allergic to any of the ingredients listed at the end of this leaflet under the heading PRODUCT DESCRIPTION.
Do not take VIREAD if you are already taking any other medicines that contain the same active ingredients.
Do not take VIREAD if you are already taking adefovir dipivoxil to treat hepatitis B virus (HBV) infection.
Do not take VIREAD if you are already taking tenofovir alafenamide to treat HIV or hepatitis B virus (HBV) infection.
Tell your doctor if you are pregnant, planning to become pregnant. The effects of VIREAD on pregnant women or their unborn babies are not known.
Tell your doctor if you are breast-feeding. Do not breast-feed if you are taking VIREAD. The active substance in this medicine (tenofovir disoproxil fumarate) has been found in breast milk at low concentrations.
Do not breast-feed if you have HIV or HBV.
If you are a woman who has or will have a baby, talk with your doctor or pharmacist about the best way to feed your baby. If your baby does not already have HIV or HBV, there is a chance that the baby can get HIV or HBV through breast-feeding.
Tell your doctor if you have kidney problems.
Tell your doctor if you have bone problems.
Tell your doctor if you have liver problems, including HBV and hepatitis C virus (HCV).
Tell your doctor if you have HIV infection.
Tell your doctor or pharmacist about all your medical conditions.
Tell your doctor or pharmacist about all the medicines you take, including prescription and non-prescription medicines and dietary supplements.
Especially tell your doctor or pharmacist if you take:
It is a good idea to keep a complete list of all the medicines that you take.
Make a new list when medicines are added or stopped. Give copies of this list to your doctor or pharmacist every time you visit your doctor or fill a prescription.
Stay under a doctor’s care when taking VIREAD
Do not change your treatment or stop treatment without first talking with your doctor.
Take VIREAD exactly as your doctor prescribed it.
Follow the directions from your doctor or pharmacist, exactly as written on the label.
Set up a dosing schedule and follow it carefully.
The usual dose of VIREAD is one tablet once a day.
If you have kidney problems, your doctor may recommend that you take VIREAD less frequently.
VIREAD is best taken with a meal or just afterwards, however taking it without food should not reduce the effectiveness of the medicine.
If you are taking VIREAD to treat HIV or if you have HIV and HBV coinfection and are taking VIREAD, always take VIREAD in combination with other anti-HIV medicines. VIREAD and other medicines like VIREAD, may be less likely to work in the future if you are not taking VIREAD with other anti-HIV medicines because you may develop resistance to those medicines. If you have any questions about what medicines you should or should not be taking, please see your doctor or pharmacist.
If you have been given VIREAD to treat CHB, you are advised to get a HIV test before you start taking VIREAD and at any time after that when there is a chance you were exposed to HIV.
When your VIREAD supply starts to run low, get more from your doctor or pharmacist. This is very important because the amount of virus in your blood may increase if the medicine is stopped for even a short time. The virus may develop resistance to VIREAD, and may become harder to treat. If you are taking VIREAD to treat CHB, stopping treatment may result in very severe hepatitis and serious liver problems (see SIDE EFFECTS).
Only take medicine that has been prescribed specifically for you.
Do not give VIREAD to others or take medicine prescribed for someone else.
It is important that you do not miss any doses.
If you miss a dose of VIREAD, take it as soon as possible and then take your next scheduled dose at its regular time.
If it is almost time for your next dose, do not take the missed dose. Wait and take the next dose at the regular time. Do not double the next dose.
Immediately telephone your doctor or Poisons Information Centre (telephone 131126), or in New Zealand the Poisons Centre (telephone 0800 764 766) or go to the accident and emergency department at your nearest hospital if you think you or anyone else may have taken too many VIREAD tablets. Do this even if there are no signs of discomfort or poisoning. This may need urgent medical attention.
Do not breast-feed. See “Before you start to take it”
Some patients taking VIREAD have experienced dizziness. Make sure you know how you react to VIREAD before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy
In clinical studies in patients with HIV the most common side effects of VIREAD are:
Less common side effects of VIREAD are:
In clinical studies in patients with CHB the only common side effect of VIREAD is:
Marketing experience has shown other side effects reported since VIREAD has been marketed include:
VIREAD may cause the following other side effects:
Kidney Problems
Some patients treated with VIREAD have had kidney problems. If you have had kidney problems in the past or need to take another drug that can cause kidney problems, your doctor may need to perform additional blood tests. Kidney problems may be associated with muscle problems and softening of the bones.
Changes in Bone Mineral Density
Laboratory tests show changes in the bones of patients treated with VIREAD. It is not known whether long-term use of VIREAD will cause damage to your bones. If you have had bone problems in the past, your doctor may need to perform additional tests or may suggest additional medication.
Lactic Acidosis
Some patients taking antiviral drugs like VIREAD have developed a condition called lactic acidosis (a build-up in the blood of lactic acid, the same substance that causes your muscles to burn during heavy exercise). Symptoms of lactic acidosis include nausea, vomiting, unusual or unexpected stomach discomfort, and weakness.
If you notice these symptoms or if your medical condition changes suddenly, call your doctor right away.
Changes in body fat
Changes in body fat have been seen in some patients taking anti-HIV medicine. These changes may include increased amount of fat in the upper back and neck (“buffalo hump”), breast, and around the main part of your body (trunk). Loss of fat from the legs, arms and face may also happen. The cause and long term health effects of these conditions are not known at this time.
Hepatic Flares
It is extremely important that you do not stop taking VIREAD without your doctor’s advice. If you have Hepatitis B infection or HIV and HBV infection together, you may have a “flare-up” of Hepatitis B if you stop taking VIREAD, where the disease suddenly returns in a worse way than before. This flare-up may lead to liver failure and possibly liver transplantation or death
After stopping VIREAD, tell your doctor immediately about any new, unusual, or worsening symptoms that you notice after stopping treatment. After you stop taking VIREAD, your doctor will still need to check your health and take blood tests to check your liver for several months.
There have been other side effects in patients taking VIREAD. However, these side effects may have been due to other medicines that patients were taking or to the illness itself.
Some of these side effects can be serious.
This list of side effects is not complete. If you have questions about side effects, ask your doctor or pharmacist.
You should report any new or continuing symptoms to your doctor or pharmacist right away.
