1. Package contents and additional information

If tenofovir has been prescribed to your child, note that all the information in this leaflet is addressed to your child (in this case, read "your child" instead of "you").

1. What is Tenofovir Disoproxil Glenmark and what is it used for

Tenofovir contains the active ingredient tenofovir disoproxil. This active ingredient is an antiretroviralor antiviral medication used to treat HIV infection, or HBV, or both. Tenofovir is a nucleotide analog reverse transcriptase inhibitor, commonly known as NtRTI, which acts by interfering with the normal function of certain enzymes (in the case of HIV, reverse transcriptase, and in hepatitis B, DNA polymerase) that are essential for the viruses to reproduce. For the treatment of HIV infection, tenofovir should always be used in combination with other medications.

Tenofovir is a medication used to treat HIV(Human Immunodeficiency Virus) infection.

The tablets are suitable for:

• adults,
• adolescents between 12 and less than 18 yearswho have already been treated with other HIV medications that are no longer fully effective due to the development of resistance, or that have caused side effects.

Tenofovir is also used to treat chronic hepatitis B, an infectioncaused by the HBV(hepatitis B virus). The tablets are suitable for:

• adults,
• adolescents between 12 and less than 18 years.

You don't have to have HIV to be treated with Tenofovir for HBV.

This medication is not a cure for HIV infection. While taking tenofovir, you may still have infections or other diseases associated with HIV infection. You may also continue to transmit HIV or HBV to others. Therefore, it is essential that you take precautions to avoid infecting others.

2. What you need to know before taking Tenofovir Disoproxil Glenmark

Do not takeTenofovir Disoproxil Glenmark:

• If you are allergicto tenofovir, tenofovir disoproxil, or any of the other components of this medication listed in section 6.

If this is the case, tell your doctor immediately and do not taketenofovir disoproxil.

Warnings andprecautions

Tenofovir does not reduce the risk of HBV transmission through sexual contact or blood contamination. You should continue to take precautions to avoid it.

Consult your doctor or pharmacist before starting to take tenofovir.

• If you have had kidney disease or if your tests have shown kidney problems. Tenofovir should not be administered to adolescents with existing kidney problems. Before starting treatment, your doctor may request that you have blood tests to evaluate your kidney function. Tenofovir may affect your kidneys during treatment. Your doctor may request that you have blood tests during treatment to monitor your kidney function. If you are an adult, your doctor may advise you to take the tablets less frequently. Do not reduce the prescribed dose unless your doctor has told you to.

Tenofovir is not usually taken with other medications that can harm your kidneys (see Taking Tenofovir Disoproxil Glenmark with other medications). If this is unavoidable, your doctor will monitor your kidney function once a week.

• If you have osteoporosis, a history of bone fractures, or bone problems

Bone problems (which manifest as persistent or worsening bone pain and sometimes end in fractures) may also occur due to damage to the renal tubular cells (see section 4, Possible side effects). Tell your doctor if you have bone pain or fractures.

Tenofovir disoproxil may also cause bone mass loss. The most significant bone loss was observed in clinical studies when patients were treated with tenofovir disoproxil in combination with a boosted protease inhibitor.

In general, the effects of tenofovir disoproxil on long-term bone health and the future risk of fractures in adult and pediatric patients are uncertain.

Some adult patients with HIV who receive combination antiretroviral therapy may develop a bone disease called osteonecrosis (death of bone tissue caused by lack of blood flow to the bone). Among the many risk factors for developing this disease are the duration of combination antiretroviral therapy, the use of corticosteroids, alcohol consumption, severe immunosuppression, and high body mass index. The symptoms of osteonecrosis are: joint stiffness, pain, and discomfort (especially in the hip, knee, and shoulder), and difficulty moving. If you notice any of these symptoms, tell your doctor.

• Tell your doctor if you have a history of liver disease, includinghepatitis.

Patients with liver disease, including chronic hepatitis B or C, treated with antiretrovirals, have a higher risk of serious and potentially life-threatening liver complications. If you have a hepatitis B infection, your doctor will carefully consider the best treatment for you. If you have a history of liver disease or chronic hepatitis B infection, your doctor may perform blood tests to monitor your liver function.

• Infections. If you have advanced HIV infection (AIDS) and have another type of infection, you may develop symptoms of infection and inflammation or worsening of the symptoms of an existing infection when you start treatment with tenofovir. These symptoms may indicate that your immune system is improving and fighting the infection. Be aware of the signs of inflammation or infection after starting to take tenofovir. If you notice signs of inflammation or infection, tell your doctor immediately.

In addition to opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you have started taking medications for the treatment of your HIV infection. Autoimmune disorders can occur many months after starting treatment. If you observe any symptoms of infection or other symptoms such as muscle weakness, weakness that starts in the hands and feet and moves up to the torso, palpitations, tremors, or hyperactivity, tell your doctor immediately to receive the necessary treatment.

• If you are over 65 years old, tell your doctor or pharmacist. Tenofovir has not been studied in patients over 65 years old. If you are over this age and have been prescribed tenofovir, your doctor will monitor you closely.

Children andadolescents

Tenofovir is suitablefor:

• adolescents infected with HIV-1 between 12 and less than 18 yearswho weigh at least35 kgand who have already been treated with other HIV medications that are no longer fully effective due to the development of resistance, or that have caused side effects.
• adolescents infected with HBV between 12 and less than 18 yearswho weigh at least35 kg.

Tenofovir is notsuitable for the following groups:

• not for children infected with HIV-1under 12 years.
• not for children infected with HBVunder 12 years.

To know the dose, see section 3, How to take Tenofovir Disoproxil Glenmark.

Other medications andTenofovir Disoproxil Glenmark

Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

• Do not stop taking any anti-HIV medicationprescribed by your doctor when you start treatment with tenofovir if you have HBV and HIV.

• Do not take tenofovir disoproxilif you are using medications that already contain tenofovir disoproxil or tenofovir alafenamide. Do not administer tenofovir with medications that contain adefovir dipivoxil (a medication used to treat chronic hepatitis B).

• It is very important that you tell your doctor if you are taking other medicationsthatcan harm yourkidneys.

These medications include:

• aminoglycosides, pentamidine, or vancomycin (used to treat bacterial infections),
• amphotericin B (used to treat fungal infections),
• foscarnet, ganciclovir, or cidofovir (used to treat viral infections),
• interleukin-2 (used to treat cancer),
• adefovir dipivoxil (used to treat HBV infection),
• tacrolimus (used to produce immune system suppression),
• non-steroidal anti-inflammatory drugs (NSAIDs, to relieve bone or muscle pain).

• Other medications that contain didanosine (for HIV infection):Taking tenofovir with other antiviral medications that contain didanosine may increase didanosine levels in your blood and may reduce the CD4 cell count. When medications containing tenofovir disoproxil and didanosine are taken together, pancreatitis and lactic acidosis (excess lactic acid in the blood) have been rarely reported, in some cases fatal. Your doctor will carefully consider whether to treat you with combinations of tenofovir and didanosine.

• It is also important that you tell your doctorif you are taking ledipasvir/sofosbuvir, sofosbuvir/velpatasvir, or sofosbuvir/velpatasvir/voxilaprevir to treat hepatitis C virus infection.

Pregnancy andbreastfeeding

If you are pregnant or breastfeeding, or think you may be pregnant or plan to become pregnant, consult your doctor or pharmacist before using this medication.

• .

• If you have been taking tenofovirduring your pregnancy, your doctor may request that you have periodic blood tests and other diagnostic tests to monitor your child's development. In children whose mothers took NtRTIs during pregnancy, the benefit of protection against HIV was greater than the risk of adverse effects.

• if you are a mother and have HBV and your baby received treatment to prevent hepatitis B transmission at birth, you may be able to breastfeed your baby, but you should talk to your doctor first to get more information.

• If you are a woman and have HIV infection, do not breastfeed your child to avoid transmitting the virus to your child through breast milk.

For adolescent/pediatric patients:

• If the girl has HBV and her baby is receiving treatment to prevent hepatitis B transmission at birth, she may be able to breastfeed her infant, but she should talk to her doctor first to get more information.

It is not recommended that women living with HIV breastfeed because HIV infection can be transmitted to the baby through breast milk. If you are breastfeeding or thinking of breastfeeding, you should consult your doctor as soon as possible.

After stopping treatment with tenofovir, some patients have presented with blood tests or symptoms indicating that their hepatitis had worsened. You may need to have blood tests for several months after stopping treatment. In patients with advanced liver disease or cirrhosis, it is not recommended to interrupt treatment as this may lead to worsening of hepatitis.

• Talk to your doctor before stopping tenofovir for any reason, particularly if you experience any side effect or if you have another illness.
• Talk to your doctor immediately if you experience any new or unusual symptoms after stopping your treatment, particularly those symptoms that you relate to hepatitis B virus infection.
• Contact your doctor before restarting tenofovir tablets.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.
