kidney function.&nbsp;Your doctor may also&nbsp;prescribe blood tests during treatment to check your kidneys.<br><\/p>\n\n\n\n<p>This medicine is not usually taken with other medicines that can damage the kidneys (see&nbsp;<em>Other medicines and Emtenef<\/em>&nbsp;).&nbsp;If this is unavoidable, your doctor will check your kidney function once a week.<br><\/p>\n\n\n\n<ul

phenobarbital, and&nbsp;phenytoin.&nbsp;If you are taking any of these medicines, your doctor may need to check how much of the medicine is in your blood to ensure that it is not affected when you take this medicine.&nbsp;Your doctor may give you another medicine for seizures.<br><\/p>\n\n\n\n<p><strong>if you have had liver disease, including&nbsp;chronic&nbsp;active&nbsp;hepatitis.&nbsp;<\/strong>Patients with liver disease, including&nbsp;chronic&nbsp;hepatitis&nbsp;B or C, who are being treated with combination antivirals are

medicine.&nbsp;<strong>If you have severe liver disease, do not take Emtenef<\/strong>&nbsp;(see earlier in section 2,&nbsp;<em>Do not take Emtenef<\/em>&nbsp;).<br><\/p>\n\n\n\n<p>If you have&nbsp;a hepatitis&nbsp;B&nbsp;infection your doctor will carefully choose the best treatment for you.&nbsp;Tenofovir disoproxil and emtricitabine, two of the active substances in this medicine, have some activity against&nbsp;hepatitis&nbsp;B&nbsp;virus&nbsp;even though emtricitabine is not approved for the treatment of&nbsp;hepatitis&nbsp;B&nbsp;infection.&nbsp;The symptoms of your&nbsp;hepatitis&nbsp;may worsen after you stop taking this medicine.&nbsp;Your doctor may then take blood samples regularly to check your liver function (see section 3,&nbsp;<em>If you stop taking Emtenef<\/em>&nbsp;).<br><\/p>\n\n\n\n<p>Whether or not you have had liver disease, your doctor will consider taking regular blood tests to check your liver function.<br><\/p>\n\n\n\n<p><strong>if you

drowsiness, difficulty concentrating, or abnormal dreams.&nbsp;<\/strong>These&nbsp;side effects&nbsp;can occur in the first 1 to 2 days after treatment and usually disappear after 2 to 4 weeks.<br><\/p>\n\n\n\n<p><strong>symptoms of the rash.&nbsp;<\/strong>This medicine may cause a rash.&nbsp;If you see symptoms of severe rash with blistering or fever, stop taking Emtenef and tell

of&nbsp;inflammation&nbsp;or&nbsp;infection<\/strong>.&nbsp;In some patients with advanced&nbsp;HIV&nbsp;&#8211;&nbsp;infection&nbsp;(&nbsp;AIDS&nbsp;) and a history of opportunistic&nbsp;infection,&nbsp;you may be signs and symptoms of&nbsp;inflammation&nbsp;from previous&nbsp;infections&nbsp;that may occur soon after anti-&nbsp;HIV&nbsp;started.&nbsp;These symptoms are probably due to an improvement in the body&#8217;s&nbsp;immune response, which enables the body to fight&nbsp;infections&nbsp;that may have been present but without any obvious symptoms.&nbsp;Tell your doctor immediately if you notice any symptoms of&nbsp;infection.<br><\/p>\n\n\n\n<p>In addition to opportunistic&nbsp;infection,&nbsp;you can autoimmune disorders (a condition in which the immune system attacks healthy body tissue) may also occur after you start taking medicines to treat your&nbsp;HIV&nbsp;&#8211;&nbsp;infection.&nbsp;Autoimmune disorders can occur several months after starting treatment.&nbsp;If you notice any symptoms of&nbsp;infection&nbsp;or other symptoms such as muscle weakness, a weakness that starts in the hands or feet and moves to the torso, palpitations, tremors, or hyperactivity, inform your doctor immediately for the necessary treatment.<br><\/p>\n\n\n\n<p><strong>skeletal problems.&nbsp;<\/strong>Some patients receiving&nbsp;combination&nbsp;antiretroviral&nbsp;therapy may develop a skeletal disease called&nbsp;osteonecrosis&nbsp;(skeletal tissue dies due to lost blood supply to the skeleton).&nbsp;Some of the many risk factors for developing the disease are long-term&nbsp;antiretroviral&nbsp;combination therapy, use of&nbsp;corticosteroids, alcohol consumption, a severe weakening of the immune system, and higher body mass index.&nbsp;Signs of&nbsp;osteonecrosis&nbsp;are stiffness in the joints and pain (especially hip, knee, and shoulders) and difficulty moving.&nbsp;Tell your doctor if you experience any of these symptoms.<br><\/p>\n\n\n\n<p>Skeletal problems (which sometimes lead to&nbsp;fractures&nbsp;) can also occur due to damage to the renal tubules (see section 4, Possible&nbsp;side effects&nbsp;).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Children and young people<\/h2>\n\n\n\n<p><strong>Emtenef should not be given to children and

result, the amount of this medicine or other medicines in the blood may be affected.&nbsp;This can lead to the medicines not working properly or the&nbsp;side effects&nbsp;getting worse.&nbsp;In some cases, your doctor may need to adjust your&nbsp;dose&nbsp;or check your blood levels.&nbsp;You must tell<strong> your doctor or pharmacist if you are taking any of the following:<\/strong><br><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Medicines containing didanosine (for&nbsp;HIV&nbsp;&#8211;&nbsp;infection&nbsp;):<\/strong>&nbsp;If you take this medicine with other antiviral medicines that contain didanosine, blood levels of didanosine and increase CD4 cell counts.&nbsp;Rare cases of pancreatitis and lactic acidosis (excess&nbsp;lactic acid&nbsp;in the blood), in some cases fatal, have been reported during concomitant treatment with drugs containing tenofovir disoproxil and didanosine.&nbsp;Your doctor will carefully consider whether you can be treated with medicines containing tenofovir and didanosine.<\/li><li><strong>Other medicines used to&nbsp;treat&nbsp;HIV&nbsp;infection: The<\/strong>&nbsp;following protease inhibitors: darunavir, indinavir, lopinavir\/ritonavir, ritonavir,r or ritonavir with an increased&nbsp;dose of&nbsp;atazanavir or saquinavir.&nbsp;Your doctor may consider giving you alternative medicines or changing the&nbsp;dose of&nbsp;one of your protease inhibitors.&nbsp;Also, tell your doctor if you are taking maraviroc.<\/li><li>Medicines used for the treatment of&nbsp;infection&nbsp;with&nbsp;the hepatitis&nbsp;C virus: boceprevir, simeprevir, sofosbuvir \/ velpatasvir, sofosbuvir \/ velpatasvir \/ voxilaprevir.<\/li><li>Medicines used to lower blood fats (also called statins):&nbsp;Atorvastatin, pravastatin,&nbsp;simvastatin.&nbsp;This medicine may reduce the number of statins in your blood.&nbsp;Your doctor will check your cholesterol level and, if necessary, consider changing your statin dose.<\/li><li>Medicines used to treat seizures (&nbsp;antiepileptic drugs&nbsp;):&nbsp;Carbamazepine,&nbsp;phenytoin, phenobarbital.&nbsp;Emtenef may reduce the number of&nbsp;antiepileptic drugs in the blood.&nbsp;Carbamazepine may reduce the amount of efavirenz, one of the ingredients of this medicine, in the blood.&nbsp;Your doctor may consider giving you another&nbsp;antiepileptic drug.<\/li><li>Drugs for the treatment of bacterial&nbsp;infection&nbsp;s, including&nbsp;tuberculosis&nbsp;and&nbsp;AIDS-related mycobacterium avium complex: Clarithromycin, rifabutin, rifampicin.&nbsp;Your doctor may consider changing your&nbsp;dose&nbsp;or giving you another&nbsp;antibiotic.&nbsp;Your doctor may also consider adding a&nbsp;dose&nbsp;of efavirenz to treat your&nbsp;HIV&nbsp;&#8211;&nbsp;infection.<\/li><li>Medicines used to treat fungal infections:&nbsp;Itraconazole or posaconazole.&nbsp;This medicine may reduce the amount of itraconazole or posaconazole in the blood.&nbsp;Your doctor may consider giving you another medicine for a fungal infection.<\/li><li>Medicines used to treat malaria:&nbsp;Atovaquone \/ proguanil or artemeter \/ lumefantrine: This medicine may reduce the amount of atovaquone \/ proguanil or artemeter \/ lumefantrine in your blood.<\/li><li>Hormonal contraceptives, such as&nbsp;birth control pills, an injected contraceptive (eg Depo-Provera), or a contraceptive implant (eg Nexplanon): You must always use a reliable barrier contraceptive method (see&nbsp;Pregnancy and breast-feeding&nbsp;).&nbsp;Emtenef may have a worse effect on hormonal contraceptives.&nbsp;Pregnancy has occurred in women taking efavirenz, one of the ingredients of this medicine, while using a contraceptive implant, although it has not been established that efavirenz treatment was the reason for the lack of contraceptive effect.<\/li><li>Sertraline,&nbsp;a medicine used to treat depression, your doctor may change your dose of sertraline.<\/li><li>Bupropion,&nbsp;a medicine used to treat depression or to help quit smoking, your doctor may change your dose of bupropion.<\/li><li>Diltiazem&nbsp;or similar medicines (so-called calcium&nbsp;channel blockers&nbsp;):&nbsp;When you start taking this medicine, your doctor may need to adjust your&nbsp;dose&nbsp;of calcium channel blockers.<\/li><li>Drugs used to prevent rejection of transplanted organs (and also called immunosuppressive drugs)&nbsp;such as cyclosporine, sirolimus, or tacrolimus.&nbsp;When you start or stop taking this medicine, your doctor will make frequent checks on your plasma levels of the immunosuppressive medicine and may need to adjust its&nbsp;dose.<\/li><li><strong>Warfarin&nbsp;or acenocoumarol<\/strong>&nbsp;(medicines used to&nbsp;inhibit&nbsp;blood&nbsp;clotting&nbsp;): Your doctor may need to adjust your&nbsp;dose&nbsp;of&nbsp;warfarin&nbsp;or acenocoumarol.<\/li><li><strong>Extract of Ginkgo biloba<\/strong>&nbsp;(an herbal medicine).<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Pregnancy, breastfeeding, and fertility<\/h2>\n\n\n\n<p>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.<br><\/p>\n\n\n\n<p><strong>Women should not become pregnant during treatment with Emtenef or for 12 weeks thereafter.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Your doctor may ask you to take a pregnancy test to make sure you are not pregnant before starting your treatment with this medicine.<br><\/p>\n\n\n\n<p><strong>If you could become pregnant during treatment with Emtenef<\/strong>, you must use a reliable barrier contraceptive method (eg condoms) together with other contraceptive methods such as tablets (&nbsp;birth control pills&nbsp;) or other hormonal contraceptive methods (eg&nbsp;implants,&nbsp;injections&nbsp;).&nbsp;Efavirenz, one of the ingredients of this medicine, may remain in the blood for some time after stopping treatment.&nbsp;You should therefore continue to use contraception, as described above, for 12 weeks after stopping Emtenef.<br><\/p>\n\n\n\n<p><strong>Tell your doctor immediately if you are pregnant or planning to become pregnant.&nbsp;<\/strong>If you are pregnant, you should only take Emtenef if you and your doctor decide that there is a clear need.<br><\/p>\n\n\n\n<p>Serious malformations have been observed in fetal animals and neonates to women treated with efavirenz during pregnancy.<br><\/p>\n\n\n\n<p>Ask your doctor or pharmacist for advice before taking any medicine.<br><\/p>\n\n\n\n<p>If you have taken Emtenef during your pregnancy, your doctor may ask you to have regular blood tests and other diagnostic tests to check your baby&#8217;s development.&nbsp;For children with a&nbsp;mother&nbsp;who has taken NRTIs during pregnancy, the benefit of&nbsp;HIV protection outweighs the&nbsp;risk of&nbsp;side effects.<br><\/p>\n\n\n\n<p><strong>Do not breast-feed during treatment with Emtenef.&nbsp;<\/strong>Both&nbsp;HIV&nbsp;and the ingredients in this medicine can be transferred to breast milk and can seriously harm your baby.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Driving and using machines<\/h2>\n\n\n\n<p><strong>Emtenef may cause dizziness, impaired concentration, and drowsiness.&nbsp;<\/strong>If you get these symptoms, do not drive, use any tools or machines.<br><\/p>\n\n\n\n<p>You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened attention.&nbsp;One of the factors that can affect your ability in these respects is the use of drugs due to their effects and\/or&nbsp;side effects.&nbsp;Descriptions of these effects and&nbsp;side effects&nbsp;can be found in other sections.&nbsp;Read all the information in this leaflet for guidance.&nbsp;If you are not sure, talk to your doctor or pharmacist.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Emtenef contains sodium<\/h2>\n\n\n\n<p>This medicine contains less than 1 mmol&nbsp;sodium&nbsp;(23 mg) per tablet, ie&nbsp;essentially &#8216;sodium-free&#8217;.&nbsp;next to &#8220;sodium-free&#8221;.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to use Emtenef<\/h2>\n\n\n\n<p>Always take this medicine exactly as your doctor or pharmacist has told you.&nbsp;Ask your doctor or pharmacist if you are unsure.<br><\/p>\n\n\n\n<p><strong>The recommended&nbsp;dose&nbsp;is:<\/strong><\/p>\n\n\n\n<p>One tablet once a day by mouth.&nbsp;Emtenef is recommended to be taken on an empty stomach (usually defined as 1 hour before or 2 hours after a meal), preferably at bedtime.&nbsp;This may help reduce certain&nbsp;side effects&nbsp;(eg dizziness, drowsiness).&nbsp;Swallow the tablet whole with water.<br><\/p>\n\n\n\n<p>Emtenef must be taken every day.<br><\/p>\n\n\n\n<p>If your doctor decides to stop one of the components of this medication, you may be given efavirenz, emtricitabine, and\/or tenofovir disoproxil separately or with other medicines to treat your&nbsp;HIV&nbsp;&#8211;&nbsp;infection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If you use more Emtenef than you should &nbsp;<\/h2>\n\n\n\n<p>If you accidentally take too many Emtenef tablets, you may be more likely to experience any&nbsp;side effects&nbsp;from this medicine (see section 4, Possible&nbsp;side effects&nbsp;).<\/p>\n\n\n\n<p>If you have ingested too much medicine or if e.g.&nbsp;If a child has inadvertently ingested the medicine, contact a doctor, hospital, or the Poison Information Center for risk assessment and advice.&nbsp;Save the tablet pack so you can easily describe what you took.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If you forget to use Emtenef<\/h2>\n\n\n\n<p>You mustn&#8217;t a&nbsp;dose&nbsp;of Emtenef.<br><\/p>\n\n\n\n<p><strong>If you miss a&nbsp;dose&nbsp;of Emtenef within 12 hours of the time it is usually taken<\/strong>, take it as soon as possible, and then take the next&nbsp;dose&nbsp;at its regular time.<br><\/p>\n\n\n\n<p><strong>If it is almost time (less than 12 hours) for the next&nbsp;dose<\/strong>, do not take the missed&nbsp;dose&nbsp;&nbsp;Wait and take the next&nbsp;dose&nbsp;at its regular time.&nbsp;Do not take a double&nbsp;dose&nbsp;to make up for a forgotten tablet.<br><\/p>\n\n\n\n<p><strong>If you vomit the tablet (within 1 hour of taking Emtenef),<\/strong>&nbsp;take a new tablet.&nbsp;Do not wait until it is time for your next tablet.&nbsp;You do not need to take a new tablet if you vomit more than 1 hour after taking the tablet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If you stop using Emtenef<\/h2>\n\n\n\n<p><strong>Do not stop taking Emtenef without talking to your doctor.&nbsp;<\/strong>Discontinuation of treatment with this medicine can seriously affect how you respond to treatment in the future.&nbsp;If you have stopped taking this medicine, talk to your doctor before taking the tablets again.&nbsp;If you have problems or need to adjust the&nbsp;dose, your doctor may consider giving you the ingredients of this medicine separately.<br><\/p>\n\n\n\n<p><strong>When your tablets start to run out<\/strong>, be sure to get more from your doctor or pharmacist.&nbsp;This is very important because the amount of virus can start to increase as soon as you stop taking the medicine, even if it is only for a short time.&nbsp;The virus can then become more difficult to treat.<br><\/p>\n\n\n\n<p><strong>If you have both&nbsp;HIV&nbsp;&#8211;&nbsp;infection&nbsp;and&nbsp;hepatitis&nbsp;B<\/strong>, it is especially important not to stop treatment without first talking to your doctor.&nbsp;Some patients&#8217; blood tests or symptoms have shown that their&nbsp;hepatitis&nbsp;worsens when treatment is stopped with emtricitabine or tenofovir disoproxil (two of the three ingredients in this medicine).&nbsp;If treatment with this medicine is stopped, your doctor may recommend that you resume&nbsp;hepatitis&nbsp;B treatment.&nbsp;You may need to submit blood samples for 4 months after stopping treatment to check your liver function.&nbsp;In some patients with advanced liver or cirrhosis of the liver, discontinuation of treatment is not recommended as this may lead to hepatitis&nbsp;one worsens, which can be life-threatening.<br><\/p>\n\n\n\n<p><strong>\u2192<\/strong>&nbsp;Tell your doctor immediately about new or unusual symptoms that occur after stopping treatment, especially symptoms associated

Possible side effects<\/h2>\n\n\n\n<p>During&nbsp;HIV&nbsp;treatment, weight gain and increased levels of&nbsp;lipids&nbsp;and&nbsp;glucose&nbsp;in the blood may occur.&nbsp;This is partly related to restored health and lifestyle, but when it comes to blood lipids, there can sometimes be a connection with&nbsp;HIV&nbsp;drugs.&nbsp;The doctor will perform tests to find such changes.<br><\/p>\n\n\n\n<p>Like all medicines, this medicine can cause&nbsp;side effects, although not everybody gets them.<br><\/p>\n\n\n\n<p><strong>Possible serious side effects: contact a doctor
