What is Tenofovir
Tenofovir disoproxil maleate is an antiviral medication used to treat two different
Chronic Hepatitis B (CHB) and
Human Immunodeficiency Virus (HIV) infection.
Tenofovir Disoproxil Mylan is a type of medicine called HBV polymerase inhibitor and
a nucleotide analog reverse transcriptase inhibitor (NRTI).
How Tenofovir Disoproxil Mylan works in the Treatment of CHB:
Tenofovir Disoproxil 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
Tenofovir Disoproxil Mylan works by interfering with the normal working of enzymes
(HBV DNA polymerase) that are essential for HBV to reproduce itself. Tenofovir Disoproxil
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 Disoproxil Mylan may help treat your hepatitis.

How Tenofovir Disoproxil Mylan works in the Treatment of HIV Infection:
Tenofovir Disoproxil 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 Disoproxil 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)
Tenofovir Disoproxil Mylan helps to block HIV- 1 reverse transcriptase, a chemical
(enzyme) in your body that is needed for HIV-1 to multiply. Tenofovir Disoproxil 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
You do not have to have HIV infection to be treated with Tenofovir Disoproxil Mylan
for HBV and vice versa.
Use in Children

you are allergic to tenofovir disoproxil maleate, tenofovir disoproxil fumarate or
any of its ingredients

or tenofovir disoproxil fumarate
you are already taking adefovir dipivoxil to treat hepatitis B virus (HBV) infection
Before you start to take it:

The effects of Tenofovir Disoproxil Mylan on pregnant women or their unborn babies
are not known.
Tell your doctor if you are breastfeeding.

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.

and non- prescription medicines and dietary supplements.
Especially tell your doctor or pharmacist if you take:
(ledipasvir/sofosbuvir) to treat your HCV infection
VIDEX, VIDEX EC
(didanosine); Tenofovir Disoproxil 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
Disoproxil Mylan together. If you are taking VIDEX and Tenofovir Disoproxil 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 Disoproxil Mylan in your blood, which could result
in more side effects. You may need to be followed more carefully if you are taking
Tenofovir Disoproxil Mylan and REYATAZ or KALETRA together. Tenofovir Disoproxil Mylan
may decrease the amount of REYATAZ in your blood. If you are taking Tenofovir Disoproxil
Mylan and REYATAZ together you should also be taking NORVIR (ritonavir).

Tenofovir Disoproxil 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.

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 Disoproxil 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 Disoproxil 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 Disoproxil 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 Disoproxil Mylan, tell your doctor immediately about any new, unusual, or
worsening symptoms that you notice after stopping treatment. After you stop taking
Tenofovir Disoproxil Mylan, your doctor will still need to check your health and take
blood tests to check your liver for several months.
