This medicine is not a cure for HIV infection. While taking Odefsey you may still develop infections or other illnesses associated with HIV infection.

• If you have liver problems or a history of liver disease, including hepatitis. Patients with liver disease including chronic hepatitis B or C, who are treated with antiretrovirals, have a higher risk of severe and potentially fatal liver complications. If you have hepatitis B infection, your doctor will carefully consider the best treatment regimen for you.
• If you have hepatitis B infection, liver problems may become worse after you stop taking Odefsey. It is important not to stop taking Odefsey without talking to your doctor: see section 3, Do not stop taking Odefsey.
• If you are taking any medicines that may cause a life-threatening irregular heartbeat (Torsades de Pointes).
• If you have had kidney disease or if tests have shown problems with your kidneys. Your doctor may order blood tests to monitor how your kidneys work when starting and during treatment with Odefsey.

Once you start taking Odefsey, look out for:

• Signs of inflammation or infection
• Joint pain, stiffness or bone problems

• If you notice any of these symptoms, tell your doctor immediately. For more information see section 4, Possible side effects.

There is a possibility that you may experience kidney problems when taking Odefsey over a long period of time (see Warnings and precautions).

Do not give this medicine to children aged 11 years or under, or weighing less than 35 kg. The use of Odefsey in children aged 11 years or under or weighing less than 35 kg has not yet been studied.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Odefsey may interact with other medicines. As a result, the amounts of Odefsey 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.

Talk to your doctor if you are taking:

• Any medicines used for treating HIV
• Any medicines containing:
  • tenofovir alafenamide
  • tenofovir disoproxil
  • lamivudine
  • adefovir dipivoxil
• Antibiotics used to treat bacterial infections containing:
  
  • clarithromycin
  • erythromycin
  These medicines can increase the amount of rilpivirine and tenofovir alafenamide (components of Odefsey) in your blood. Your doctor will give you a different medicine.
• Antifungal medicines used to treat fungal infections:
  
  • ketoconazole
  • fluconazole
  • itraconazole
  • posaconazole
  • voriconazole
  These medicines can increase the amount of rilpivirine and tenofovir alafenamide (components of Odefsey) in your blood. Your doctor will give you a different medicine.
• Medicines for stomach ulcers, heartburn or acid reflux such as:
  • antacids (aluminium/magnesium hydroxide or calcium carbonate)
  • H₂-antagonists (famotidine, cimetidine, nizatidine or ranitidine)
    These medicines can decrease the amount of rilpivirine (a component of Odefsey) in your blood. If you are taking one of these medicines your doctor will either give you a different medicine, or recommend how and when you take that medicine:
  • If you are taking an antacid, take it at least 2 hours before or at least 4 hours after Odefsey.
  • If you are taking an H₂-antagonist, take it at least 12 hours before or at least 4 hours after Odefsey. H₂-antagonists can only be taken once a day if you take Odefsey.
    H₂-antagonists should not be taken in a twice a day regimen. Talk to your doctor about an alternative regimen (see How to take Odefsey).

  This medicine can increase the amount of rilpivirine and tenofovir alafenamide (components of Odefsey) in your blood. Your doctor will give you a different medicine.
• Methadone, a medicine used to treat opiate addiction, as your doctor may need to change your methadone dose.
• Dabigatran etexilate, a medicine used to treat heart conditions, as your doctor may need to monitor the levels of this medicine in your blood.

• Tell your doctor if you are taking any of these medicines. Do not stop your treatment without contacting your doctor.

• If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
• Use effective contraception while taking Odefsey.

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

If you have taken Odefsey 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 nucleoside reverse transcriptase inhibitors (NRTIs) during pregnancy, the benefit from the protection against HIV outweighed the risk of side effects.

Do not breast-feed during treatment with Odefsey. This is because some of the active substances in this medicine pass into human breast milk.

Breast-feeding is not recommended in women living with HIV because HIV infection can be passed on to the baby in breast milk.

If you are breast-feeding, or thinking about breast-feeding, you should discuss it with your doctor as soon as possible.

Do not drive or operate machines if you feel tired, sleepy or dizzy after taking your medicine.

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

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

• If any of these applies to you, talk to your doctor before taking Odefsey.

Adults: one tablet each day with food

Adolescents 12 years of age and older, who weigh at least 35 kg: one tablet each day with food

It is important to take Odefsey with food to get the right levels of active substance in your body. A nutritional drink alone does not replace food.

It is recommended not to chew, crush or split the tablet due to the bitter taste.

If you are taking an antacid such as aluminium/magnesium hydroxide, or calcium carbonate, take it at least 2 hours before or at least 4 hours after Odefsey.

If you are taking an H₂-antagonist such as famotidine, cimetidine, nizatidine or ranitidine, take it at least 12 hours before or at least 4 hours after Odefsey. H₂-antagonists can only be taken once a day if you take Odefsey. H₂-antagonists should not be taken twice a day. Talk to your doctor about an alternative regimen.

If you are on dialysis, take your daily dose of Odefsey following completion of dialysis.

If you accidentally take more than the recommended dose of Odefsey 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 immediately for advice. Keep or take the tablet bottle with you so that you can easily describe what you have taken.

It is important not to miss a dose of Odefsey.

If you do miss a dose:

• If you notice within 12 hours of the time you usually take Odefsey, you must take the tablet as soon as possible. Always take the tablet with food. Then take the next dose as usual.
• If you notice 12 hours or more after the time you usually take Odefsey, then do not take the missed dose. Wait and take the next dose, with food, at your usual time.

If you vomit less than 4 hours after taking Odefsey, take another tablet with food. If you vomit more than 4 hours after taking Odefsey you do not need to take another tablet until your next regularly scheduled tablet.

Do not stop taking Odefsey without talking to your doctor. Stopping Odefsey can seriously affect your response to future treatment. If Odefsey is stopped for any reason, speak to your doctor before you restart taking Odefsey tablets.

When your supply of Odefsey 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 disease may then become harder to treat.

If you have both HIV infection and hepatitis B, it is especially important not to stop your Odefsey treatment without talking to your doctor first. You may require blood tests for several 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.

• Any signs of inflammation or infection. In some patients with advanced HIV infection (AIDS) and a history of opportunistic infections (infections that occur in people with a weak immune system), signs and symptoms of inflammation from previous infections may occur soon after HIV treatment is started. It is thought that these symptoms are due to an improvement in the body’s immune response, enabling the body to fight infections that may have been present with no obvious symptoms.
• Autoimmune disorders, when the immune system attacks healthy body tissue, may also occur after you start taking medicines for HIV infection. Autoimmune disorders may occur many months after the start of treatment. Look out for 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

• If you notice these or any symptoms of inflammation or infection, tell your doctor immediately.

• Bone problems. Some patients taking combination antiretroviral medicines such as Odefsey may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). Taking this type of medicine for a long time, taking corticosteroids, drinking alcohol, having a very weak immune system, and being overweight, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are:
  • joint stiffness
  • joint aches and pains (especially of the hip, knee and shoulder)
  • difficulty with movement

• If you notice any of these symptoms tell your doctor.

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.
