emtricitabine / tenofovir disoproxil

What Emtricitabine / Tenofovir disoproxil Sandoz is and what it is used for

Emtricitabine / Tenofovir disoproxil Sandoz contains two active substances,  emtricitabine and tenofovir disoproxil . Both of these active substances are antiretroviral drugs used to treat HIV – infection. Emtricitabine is a nucleoside reverse transcriptase inhibitor and tenofovir is a nucleotide reverse transcriptase inhibitor. However, both are commonly called NRTIs and act by affecting the normal function of an enzyme (reverse transcriptase) that the virus needs for its reproduction (propagation).

  • Emtricitabine / Tenofovir disoproxil Sandoz is a treatment for human immunodeficiency virus infection ( HIV- 1 )  in adults.
  • It is also used to treat HIV in adolescents aged 12 to 18 years who weigh at least 35 kg and who have already been treated with other HIV medicines that are no longer effective or that have caused side effects.
    • Emtricitabine / Tenofovir disoproxil Sandoz should always be taken in combination with other anti- HIV medicines.
    • Emtricitabine / Tenofovir disoproxil Sandoz can be used instead of separate administration of emtricitabine and tenofovir disoproxil at the same dose .

People who are HIV -positive can still transmit HIV -smitten when taking this medicine, even though the risk is reduced with effective antiretroviral treatment. Discuss the necessary steps to avoid infecting others with your doctor.

This medicine does not cure HIV – infection. While taking emtricitabine/tenofovir disoproxil Sandoz may still develop infections you or other illnesses associated with HIV – infection.

  • Emtricitabine / Tenofovir disoproxil Sandoz is also used to reduce the risk of HIV- 1 infection in adults and adolescents 12 years of age and up to 18 years of age weighing at least 35 kg, when taken daily with safe sex: See Section 2 for a list of precautions that can be taken against HIV – infection.

Emtricitabine and tenofovir disoproxil contained in Emtricitabine / Tenofovir disoproxil Sandoz may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

While taking Emtricitabine / Tenofovir disoproxil Sandoz for treatment of HIV or to reduce the risk of getting HIV:

  • Emtricitabine / Tenofovir disoproxil Sandoz may affect your kidneys. Before and during treatment, your doctor may prescribe some blood tests to measure your kidney function. Tell your doctor if you have a history of kidney disease or if tests have shown that you have kidney problems. Emtricitabine / Tenofovir disoproxil Sandoz should not be used in adolescents with pre-existing kidney problems. If you have kidney problems, your doctor may advise you to stop taking Emtricitabine / Tenofovir disoproxil Sandoz or, if you already have HIV, to take the tablets less often. Emtricitabine / Tenofovir disoproxil Sandoz is not recommended if you have severe kidney disease or if you are on dialysis.
