1. What Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is and what it is used for

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva contains three active substances that are used to treat human immunodeficiency virus (HIV) infection:

  • Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI)
  • Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI)
  • Tenofovir is a nucleotide reverse transcriptase inhibitor (NtRTI)

Each of these active substances, also known as antiretroviral medicines, work by interfering with an enzyme (reverse transcriptase) that is essential for the virus to multiply.

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is a treatment for Human Immunodeficiency Virus (HIV)

infection in adults aged 18 years and over who have previously been treated with other antiretroviral medicines and have their HIV-1 infection under control for at least three months. Patients must not have experienced failure of a previous HIV therapy.

2. What you need to know before you take Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva

Warnings and precautions

Talk to your doctor or pharmacist before taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva.

  • You can still pass on HIV when taking this medicine, although the risk is lowered by effective antiretroviral therapy. Discuss with your doctor the precautions needed to avoid infecting other people. This medicine is not a cure for HIV infection. While taking Efavirenz/ Emtricitabine/ Tenofovir disoproxil Zentiva you may still develop infections or other illnesses associated with HIV infection.
  • You must remain under the care of your doctor while taking Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva.
  • Tell your doctor:
    • if you are taking other medicines that contain efavirenz, emtricitabine, tenofovir disoproxil, tenofovir alafenamide or lamivudine or adefovir dipivoxil. Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva should not be taken with any of these medicines.
    • if you have or have had kidney disease, or if tests have shown problems with your kidneys.
      Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is not recommended if you have moderate to severe kidney disease.
      Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva may affect your kidneys. Before starting treatment, your doctor may order blood tests to assess kidney function. Your doctor may also order blood tests during treatment to monitor your kidneys.
      Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is not usually taken with other medicines that can damage your kidneys (see Other medicines and Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva). If this is unavoidable, your doctor will monitor your kidney function once a week.
    • if you have a heart disorder, such as abnormal electrical signal called prolongation of the QT interval.
    • if you have a history of mental illness, including depression, or of substance or alcohol abuse. Tell your doctor immediately if you feel depressed, have suicidal thoughts or have strange thoughts (see section 4, Possible side effects).
    • if you have a history of convulsions (fits or seizures) or if you are being treated with anticonvulsant therapy such as carbamazepine, phenobarbital and phenytoin. If you are taking any of these medicines, your doctor may need to check the level of anticonvulsant medicine in your blood to ensure that it is not affected while taking Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva. Your doctor may give you a different anticonvulsant.
    • if you have a history of liver disease, including chronic active hepatitis. Patients with liver disease including chronic hepatitis B or C, who are treated with combination antiretrovirals, have a higher risk of severe and potentially life-threatening liver problems. Your doctor may conduct blood tests in order to check how well your liver is working or may switch you to another medicine. If you have severe liver disease, do not take Efavirenz/ Emtricitabine/ Tenofovir disoproxil Zentiva (see earlier in section 2, Do not take Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva).

If you have hepatitis B infection, your doctor will carefully consider the best treatment regimen for you. Tenofovir disoproxil and emtricitabine, two of the active substances in Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva, show some activity against hepatitis B virus although emtricitabine is not approved for the treatment of hepatitis B infection.

Symptoms of your hepatitis may become worse after discontinuation of Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva. Your doctor may then conduct blood tests at regular intervals in order to check how well your liver is working (see section 3, If you stop taking Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva).

  • Independent of a history of liver disease, your doctor will consider regular blood tests to check how your liver is working.
  • if you are over 65. Insufficient numbers of patients over 65 years of age have been studied. If you are over 65 years of age and are prescribed Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva, your doctor will monitor you carefully.
  • Once you start taking Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva, look out for:
    • signs of dizziness, difficulty sleeping, drowsiness, difficulty concentrating or abnormal dreaming. These side effects may start in the first 1 or 2 days of treatment and usually go away after the first 2 to 4 weeks.
    • any signs of skin rash. Rashes may be caused by Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva. If you see any signs of a severe rash with blistering or fever, stop taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva and tell your doctor at once. If you had a rash while taking another NNRTI, you may be at higher risk of getting a rash with Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva.
    • any signs of inflammation or infection. In some patients with advanced HIV infection (AIDS) and a history of opportunistic infection, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to improvement in the body’s immune response, enabling the body to fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please tell your doctor at once.
      In addition to the opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in the hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.
    • bone problems. Some patients taking combination antiretroviral therapy may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). The length of combination antiretroviral therapy, corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index, among others, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are joint stiffness, aches and pains (especially of the hip, knee and shoulder) and difficulty in movement. If you notice any of these symptoms please inform your doctor.
      Bone problems (sometimes resulting in fractures) may also occur due to damage to kidney tubule cells (see section 4, Possible side effects).

Children and adolescents

  • Do not give Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva to children and adolescents under 18 years of age. The use of Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva in children and adolescents has not been studied.

Other medicines and Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva

You must not take Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva with certain medicines. These are listed under Do not take Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva, at the start of section 2. They include some common medicines and some herbal preparations (including St. John’s wort) which can cause serious interactions.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Also, Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva should not be taken with any other medicines that contain efavirenz (unless recommended by your doctor), emtricitabine, tenofovir disoproxil, tenofovir alafenamide, or lamivudine or adefovir dipivoxil.

Tell your doctor if you are taking other medicines which may damage your kidneys. Some examples include:

  • aminoglycosides, vancomycin (medicines for bacterial infections)
  • foscarnet, ganciclovir, cidofovir (medicines for viral infections)
  • amphotericin B, pentamidine (medicines for fungal infections)
  • interleukin-2 (to treat cancer)
  • non-steroidal anti-inflammatory drugs (NSAIDs, to relieve bone or muscle pains)

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva may interact with other medicines, including herbal preparations such as Ginkgo biloba extracts. As a result, the amounts of Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva or other medicines in your blood may be affected. This may stop your medicines from working properly, or may make any side effects worse. In some cases, your doctor may need to adjust your dose or check your blood levels. It is important to tell your doctor or pharmacist if you are taking any of the following:

  • Medicines containing didanosine (for HIV infection): Taking Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva with other antiviral medicines that contain didanosine can raise the levels of didanosine in your blood and may reduce CD4 cell counts. Inflammation of the pancreas and lactic acidosis (excess lactic acid in the blood), which sometimes caused death, have been reported rarely when medicines containing tenofovir disoproxil and didanosine were taken together. Your doctor will carefully consider whether to treat you with medicines containing tenofovir and didanosine.
  • Other medicines used for HIV infection: The following protease inhibitors: darunavir, indinavir, lopinavir/ritonavir, ritonavir, or ritonavir boosted atazanavir or saquinavir. Your doctor may consider giving you an alternative medicine or changing the dose of the protease inhibitors. Also, tell your doctor if you are taking maraviroc.
  • Medicines used to treat infection with the hepatitis C virus: boceprevir, elbasvir/grazoprevir, simeprevir, sofosbuvir/velpatasvir, sofosbuvir/velpatasvir/voxilaprevir.
  • Medicines used to lower blood fats (also called statins): Atorvastatin, pravastatin, simvastatin. Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva can reduce the amount of statins in your blood. Your doctor will check your cholesterol levels and will consider changing the dose of your statin, if needed.
  • Medicines used to treat convulsions/seizures (anticonvulsants): Carbamazepine, phenytoin, phenobarbital. Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva can reduce the amount of the anticonvulsant in your blood.
  • Carbamazepine can reduce the amount of efavirenz, one of the components of Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva, in your blood. Your doctor may need to consider giving you a different anticonvulsant.
  • Medicines used to treat bacterial infections, including tuberculosis and AIDS-related mycobacterium avium complex: Clarithromycin, rifabutin, rifampicin. Your doctor may need to consider changing your dose or giving you an alternative antibiotic. In addition, your doctor may consider giving you an additional dose of efavirenz to treat your HIV infection.
  • Medicines used to treat fungal infections (antifungals): Itraconazole or posaconazole. Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva can reduce the amount of itraconazole or posaconazole in your blood. Your doctor may need to consider giving you a different antifungal.
  • Medicines used to treat malaria: Atovaquone/proguanil or artemether/ lumefantrine. Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva may reduce the amount of atovaquone/ proguanil or artemether/ lumefantrine in your blood.
  • Hormonal contraceptive, such as birth control pills, an injected contraceptive (for example, Depo-Provera), or a contraceptive implant (for example, Implanon): You must also use a reliable barrier method of contraception (see Pregnancy and breast-feeding). Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva may make hormonal contraceptives less likely to work. Pregnancies have occurred in women taking efavirenz, a component of Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva, while using a contraceptive implant, although it has not been established that the efavirenz therapy caused the contraceptive to fail.
  • Sertraline, a medicine used to treat depression, as your doctor may need to change your dose of sertraline.
  • Bupropion, a medicine used to treat depression or to help you stop smoking, as your doctor may need to change your dose of bupropion.
  • Diltiazem or similar medicines (called calcium channel blockers): When you start taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva, your doctor may need to adjust your dose of the calcium channel blocker.
  • Medicines used to prevent organ transplant rejection (also called immunosuppressants), such as cyclosporine, sirolimus or tacrolimus. When you start or stop taking Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva your doctor will closely monitor your plasma levels of the immunosuppressant and may need to adjust its dose.
  • Warfarin or acenocoumarol (medicines used to reduce clotting of the blood): Your doctor may need to adjust your dose of warfarin or acenocoumarol.
  • Ginkgo biloba extracts (herbal preparation).

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Women should not get pregnant during treatment with Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva and for 12 weeks thereafter. Your doctor may require you to take a pregnancy test to ensure you are not pregnant before starting treatment with Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva.

If you could get pregnant while receiving Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva, you need to use a reliable form of barrier contraception (for example, a condom) with other methods of contraception including oral (pill) or other hormonal contraceptives (for example, implants, injection). Efavirenz, one of the active components of Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva, may remain in your blood for a time after therapy is stopped. Therefore, you should continue to use contraceptive measures, as above, for 12 weeks after you stop taking Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva.

Tell your doctor immediately if you are pregnant or intend to become pregnant. If you are pregnant, you should take Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva only if you and your doctor decide it is clearly needed.

Serious birth defects have been seen in unborn animals and in the babies of women treated with efavirenz during pregnancy.

Ask your doctor or pharmacist for advice before taking any medicine.

If you have taken Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva during your pregnancy, your doctor may request regular blood tests and other diagnostic tests to monitor the development of your child. In children whose mothers took NRTIs during pregnancy, the benefit from the protection against HIV outweighed the risk of side effects.

Do not breast-feed during treatment with Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva. Both HIV and the ingredients of Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva may pass through breast milk and cause serious harm to your baby.

Driving and using machines

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva may cause dizziness, impaired concentration and drowsiness.

If you are affected, do not drive and do not use any tools or machines.

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially “sodium free”.

3. How to take Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is:

One tablet taken each day by mouth.

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva should be taken on an empty stomach (commonly defined as 1 hour before or 2 hours after a meal) preferably at bedtime. This may make some side effects (for example, dizziness, drowsiness) less troublesome. Swallow Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva whole with water.

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva must be taken every day.

If your doctor decides to stop one of the components of Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva, you may be given efavirenz, emtricitabine and/or tenofovir disoproxil separately or with other medicines for the treatment of your HIV infection.

Removing the child resistant cap

Open bottles by pressing the child resistant cap down and turning it counter-clock wise.

If you take more Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva than you should

If you accidentally take too many Efavirenz/ Emtricitabine/ Tenofovir disoproxil Zentiva tablets you may be at increased risk of experiencing possible side effects with this medicine (see section 4, Possible side effects). Contact your doctor or nearest emergency department for advice. Keep the tablet bottle with you so that you can easily describe what you have taken.

If you forget to take Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva

It is important not to miss a dose of Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva.

If you do miss a dose of Efavirenz/ Emtricitabine/Tenofovir disoproxil Zentiva within 12 hours of when it is usually taken, take it as soon as you can, and then take your next dose at its regular time.

If it is almost time (less than 12 hours) for your next dose anyway, do not take the missed dose. Wait and take the next dose at the regular time. Do not take a double dose to make up for a forgotten tablet.

If you throw up the tablet (within 1 hour after taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva, you should take another tablet. Do not wait until your next dose is due. You do not need to take another tablet if you were sick more than 1 hour after taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva.

If you stop taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva

Don’t stop taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva without talking to your doctor. Stopping Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva can seriously affect your response to future treatment. If Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is stopped, speak to your doctor before you restart taking Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva tablets. Your doctor may consider giving you the components of Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva separately if you are having problems or need your dose adjusted.

When your supply of Efavirenz/Emtricitabine/ Tenofovir disoproxil Zentiva starts to run low, get more from your doctor or pharmacist. This is very important because the amount of virus may start to increase if the medicine is stopped for even a short time. The virus may then become harder to treat.

If you have both HIV infection and hepatitis B, it is especially important not to stop your Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva treatment without talking to your doctor first. Some patients have had blood tests or symptoms indicating that their hepatitis has got worse after stopping emtricitabine or tenofovir disoproxil (two of the three components of Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva). If Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is stopped your doctor may recommend that you resume hepatitis B treatment. You may require blood tests to check how your liver is working for 4 months after stopping treatment. In some patients with advanced liver disease or cirrhosis, stopping treatment is not recommended as this may lead to worsening of your hepatitis, which may be life-threatening.

Tell your doctor immediately about new or unusual symptoms after you stop treatment, particularly symptoms you associate with hepatitis B infection.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

During HIV therapy there may be an increase in weight and in levels of blood lipids and glucose. This is partly linked to restored health and life style, and in the case of blood lipids sometimes to the HIV medicines themselves. Your doctor will test for these changes.

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Possible serious side effects: tell your doctor immediately

  • Lactic acidosis (excess lactic acid in the blood) is a rare (may affect up to 1 in every 1,000 patients) but serious side effect that can be fatal. The following side effects may be signs of lactic acidosis:
