What is Tenofovir
Tenofovir disoproxil maleate is an antiviral medication used to treat two different viruses;
Chronic Hepatitis B (CHB) and
Human Immunodeficiency Virus (HIV) infection.
Tenofovir Mylan is a type of medicine called HBV polymerase inhibitor and a nucleotide analog reverse transcriptase inhibitor
How Tenofovir Mylan works in the Treatment of CHB:
Tenofovir Mylan 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.
Tenofovir Mylan works by interfering with the normal working of enzymes (HBV DNA polymerase) that are essential for HBV to
reproduce itself. Tenofovir Mylan 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 Tenofovir Mylan may help treat your hepatitis.
Sometimes viruses change in your body and medicines no longer work. This is called drug resistance.
How Tenofovir Mylan works in the Treatment of HIV Infection:
Tenofovir Mylan is also used to treat HIV infection in adults and paediatric patients aged 12 years and older and weighing
at least 35 kg.
Tenofovir Mylan 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.
Tenofovir Mylan helps to block HIV- 1 reverse transcriptase, a chemical (enzyme) in your body that is needed for HIV-1 to
multiply. Tenofovir Mylan 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 Tenofovir Mylan for HBV and vice versa.
Use in Children
Tenofovir Mylan is for adults and paediatric patients aged 12 years and older and weighing at least 35 kg.
Does Tenofovir Mylan cure HIV or AIDS?
Tenofovir Mylan does not cure HIV infection or AIDS.
The long term effects of Tenofovir Mylan are not known at this time. People taking Tenofovir Mylan 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:
herpes virus infections,
and Mycobacterium avium complex (MAC) infections.
Does Tenofovir Mylan reduce the risk of passing HIV-1 or HBV to others?
Tenofovir Mylan 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.
Before you take Tenofovir Mylan
Who must not take it
Together with your doctor, you need to decide whether Tenofovir Mylan is right for you.
Do not take Tenofovir Mylan if:
you are allergic to tenofovir disoproxil maleate, tenofovir disoproxil fumarate or any of its ingredients
you are already taking a combination tablet containing tenofovir disoproxil maleate or tenofovir disoproxil fumarate
you are already taking adefovir dipivoxil to treat hepatitis B virus (HBV) infection
Before you start to take it:
Tell your doctor if you are pregnant, planning to become pregnant.
The effects of Tenofovir Mylan on pregnant women or their unborn babies are not known.
Tell your doctor if you are breastfeeding.
Do not breast-feed if you are taking Tenofovir Mylan. The active substance in this medicine (tenofovir disoproxil maleate)
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.
Taking other medicines
Tell your doctor or pharmacist about all the medicines you take, including prescription and non- prescription medicines and
Especially tell your doctor or pharmacist if you take:
(ledipasvir/sofosbuvir) to treat your HCV infection
VIDEX, VIDEX EC
(didanosine); Tenofovir Mylan may increase the amount of VIDEX in your blood. You may need to be followed more carefully if
you are taking VIDEX and Tenofovir Mylan together. If you are taking VIDEX and Tenofovir Mylan together, your doctor may need
to reduce your dose of VIDEX
REYATAZ (atazanavir sulfate) or KALETRA (lopinavir/ritonavir); These medicines may increase the amount of Tenofovir Mylan
in your blood, which could result in more side effects. You may need to be followed more carefully if you are taking Tenofovir
Mylan and REYATAZ or KALETRA together. Tenofovir Mylan may decrease the amount of REYATAZ in your blood. If you are taking
Tenofovir Mylan and REYATAZ together you should also be taking NORVIR (ritonavir).
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.
How to take Tenofovir Mylan
Stay under a doctor's care when taking Tenofovir Mylan.
Do not change your treatment or stop treatment without first talking with your doctor.
Take Tenofovir Mylan 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.
How much to take
The usual dose of Tenofovir Mylan is one tablet once a day.
If you have kidney problems, your doctor may recommend that you take Tenofovir Mylan less frequently.
How to take it
Tenofovir Mylan 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 Tenofovir Mylan to treat HIV or if you have HIV and HBV coinfection and are taking Tenofovir Mylan, always
take Tenofovir Mylan in combination with other anti-HIV medicines.
Tenofovir Mylan and other medicines like Tenofovir Mylan, may be less likely to work in the future if you are not taking Tenofovir
Mylan 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 Tenofovir Mylan to treat CHB, you are advised to get a HIV test before you start taking Tenofovir Mylan
and at any time after that when there is a chance you were exposed to HIV.
When your Tenofovir Mylan 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 Tenofovir Mylan, and may become harder to treat. If you are taking Tenofovir Mylan
to treat CHB, stopping treatment may result in very severe hepatitis and serious liver problems (see WHAT ARE THE POSSIBLE
SIDE EFFECTS OF Tenofovir Mylan).
Only take medicine that has been prescribed specifically for you.
Do not give Tenofovir Mylan to others or take medicine prescribed for someone else.
If you forget to take Tenofovir Mylan?
It is important that you do not miss any doses.
If you miss a dose of Tenofovir Mylan, 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.
If you take too much (overdose)?
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 Tenofovir Mylan tablets. Do this even if there are no signs of discomfort or poisoning. This may need
urgent medical attention.
While you are taking Tenofovir Mylan
Things you must not do
Do not breast-feed. See "Before you start to take it"
Things to be careful of
Some patients taking Tenofovir Mylan have experienced dizziness. Make sure you know how you react to Tenofovir Mylan 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 Tenofovir Mylan are:
Less common side effects include:
flatulence (intestinal gas).
In clinical studies in patients with CHB: The only common side effect of Tenofovir Mylan is:
Marketing experience has shown other side effects reported since tenofovir disoproxil has been marketed include:
low blood phosphate,
shortness of breath,
increased liver enzymes,
inflammation of the liver,
inflammation of the pancreas,
Tenofovir Mylan may cause the following other side effects
Some patients treated with tenofovir disoproxil 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 tenofovir disoproxil. It is not known whether long-term
use of Tenofovir Mylan 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.
Some patients taking antiviral drugs like Tenofovir Mylan 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.
It is extremely important that you do not stop taking Tenofovir Mylan 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 Tenofovir Mylan,
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 Tenofovir Mylan, tell your doctor immediately about any new, unusual, or worsening
symptoms that you notice after stopping treatment. After you stop taking Tenofovir Mylan, 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 tenofovir disoproxil.
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.
Your doctor or pharmacist may be able to help you manage these side effects.
