Contents of the package leaflet
Abacavir Tarbis is used to treat HIV infection.
Abacavir Tarbis contains the active substance abacavir. Abacavir belongs to a group of antiretroviral medicines called nucleoside analogue reverse transcriptase inhibitors(NRTIs).
Abacavir Tarbis does not completely cure HIV infection; it reduces the amount of virus in your body and keeps it at a low level. It also increases the number of CD4 cells in your blood. CD4 cells are a type of white blood cell that plays an important role in helping your body fight infection.
Not everyone responds to treatment with Abacavir Tarbis in the same way. Your doctor will monitor the effectiveness of your treatment.
Do not take Abacavir Tarbis
Read the information about hypersensitivity reactions in section 4 of this leaflet carefully.
Talk to your doctorif you think any of these situations apply to you.
Be especially careful with Abacavir Tarbis
Some people who take Abacavir Tarbis for HIV have a higher risk of serious side effects. You need to know that there is a higher risk:
Talk to your doctorif you have any of these conditions. You may need to have extra checks, including blood tests, while you are taking this medicine. For more information, see section 4.
Hypersensitivity reactions to abacavir
Even patients who do not have the HLA-B*5701 gene may still develop a hypersensitivity reaction(a serious allergic reaction).
Read the information about hypersensitivity reactions in section 4 of this leaflet carefully.
Risk of cardiovascular events
It cannot be excluded that abacavir may increase the risk of cardiovascular events.
Tell your doctorif you have cardiovascular problems, if you smoke, or if you have diseases that may increase the risk of cardiovascular disease, such as high blood pressure and diabetes. Do not stop taking Abacavir Tarbis unless your doctor advises you to.
Be aware of important symptoms
Some people who take medicines for HIV infection develop other conditions, which can be serious. You need to know what important signs and symptoms to look out for while you are taking Abacavir Tarbis.
Read the information about “Other possible side effects of combination therapy for HIV” in section 4 of this leaflet.
Protect others
HIV infection is spread by sexual contact with someone who has the infection or by transfer of infected blood (for example, by sharing needles). While you are taking this medicine, you can still pass HIV to others, although effective antiretroviral therapy reduces the risk. Ask your doctor about the precautions you need to take to avoid infecting others.
Taking Abacavir Tarbis with other medicines
Tell your doctor or pharmacistif you are taking or have recently takenany other medicines, including those obtained without a prescription, including herbal medicines. Remember to tell your doctor or pharmacist if you start taking any new medicine while you are taking Abacavir Tarbis.
Some medicines interact with Abacavir Tarbis
These include:
Tell your doctorif you are taking phenytoin. Your doctor may need to monitor you while you are taking Abacavir Tarbis.
Tell your doctorif you are taking methadone.
Pregnancy
Abacavir Tarbis is not recommended during pregnancy. Abacavir Tarbis and similar medicines may cause side effects in babies during pregnancy. If you have taken Abacavir Tarbis during your pregnancy, your doctor may ask for blood tests and other diagnostic tests to monitor your child's development. In children whose mothers took NRTIs during pregnancy, the benefit of protection against HIV was greater than the risk of side effects.
Breast-feeding
Women with HIV infection should not breast-feed their babies, because HIV infection can be passed to the baby through breast milk. A small amount of the ingredients of Abacavir Tarbis can also pass into breast milk.
If you are breast-feeding, or think you might want to, consult your doctor immediately.

If you have stopped taking Abacavir Tarbis
If for any reason you have stopped taking Abacavir Tarbis — especially because you think you have had side effects or because of another illness:
Talk to your doctor before you start taking it again. Your doctor will check whether your symptoms were related to a hypersensitivity reaction. If your doctor thinks that they may have been, they will tell you that you must never take Abacavir Tarbis again or take any other medicine that contains abacavir (e.g., Triumeq, Trizivir, or Kivexa). It is very important that you follow this advice.

During HIV treatment, there may be an increase in weight and glucose and lipid levels in the blood. This may be partly related to the recovery of health and lifestyle, and in the case of blood lipids, sometimes to HIV medications themselves. Your doctor will monitor these changes.
Like all medications, this medication can produce adverse effects, although not all people suffer from them.
When you are undergoing HIV treatment, it can be difficult to distinguish whether a symptom is an adverse effect of Abacavir Tarbis or other medications you are taking, or is due to an effect of the disease caused by HIV. Therefore, it is very important that you inform your doctor about any change in your health.
Even patients who do not have the HLA-B*5701 gene can develop a hypersensitivity reaction(a severe allergic reaction), described in this prospectus in the section called “Hypersensitivity Reactions”.
It is very important that you read and understand the information about this severe reaction.
In addition to the adverse effects listed below for Abacavir Tarbis, other disorders can develop during combined HIV treatment.
It is essential that you read the information under the heading “Other Possible Adverse Effects of Combined HIV Treatment”.
Hypersensitivity Reactions
Abacavir Tarbiscontains abacavir(the active ingredient also present in Trizivir, Triumeq, and Kivexa).
Abacavir can cause a severe allergic reaction known as a hypersensitivity reaction. These hypersensitivity reactions have been observed more frequently in people taking medications containing abacavir.
Who suffers from these reactions?
Anyone taking Abacavir Tarbis could develop a hypersensitivity reaction to abacavir, which can be life-threatening if they continue taking Abacavir Tarbis.
You are more likely to develop this reaction if you have a gene called HLA-B*5701(but you can suffer from this reaction even if you do not have this gene). Before starting treatment with Abacavir Tarbis, you should have undergone a test to detect this gene. If you know you have this gene, tell your doctor before taking Abacavir Tarbis.
About 3 to 4 out of every 100 patients treated with abacavir in a clinical trial, who did not have the HLA-B*5701 gene, developed a hypersensitivity reaction.
What are the symptoms?
The most frequent symptoms are:
Other signs frequently observed are:
Other symptoms may include:
pain in the joints or muscles, swelling of the neck, difficulty breathing, sore throat, cough, occasional headache, eye inflammation (conjunctivitis), mouth ulcers, low blood pressure, and numbness or tingling of the hands or feet.
When do these reactions occur?
Allergic reactions can appear at any time during treatment with Abacavir Tarbis, but it is more likely that they will occur in the first 6 weeks of treatment.
If you are caring for a child who is being treated with Abacavir Tarbis, it is essential that you understand the information about this hypersensitivity reaction. If the child experiences the symptoms described below, it is crucialthat you follow the indicated instructions.
Contact your doctor immediately:
1if you have a skin rash OR
2if you have symptoms included in at least 2 of the following groups:
Your doctor may advise you to stop taking Abacavir Tarbis.
While taking Abacavir Tarbis, always carry the Patient Information Card with you.
If you have stopped taking Abacavir Tarbis
If you have stopped taking Abacavir Tarbis due to a hypersensitivity reaction, NEVER AGAINtake Abacavir Tarbis or any other medication containing abacavir (e.g., Trizivir, Triumeq, or Kivexa). If you do, you may experience a drop in blood pressure that can be life-threatening or cause death within hours.
If you have interrupted treatment with Abacavir Tarbis — especially because you think you have adverse effects or another illness:
Consult your doctor before restarting treatment.
Your doctor will check if your symptoms were related to a hypersensitivity reaction. If your doctor considers that there may have been a relationship, they will indicatethat you should never againtake Abacavir Tarbis or any other medication containing abacavir (e.g., Trizivir, Triumeq, or Kivexa). It is essential that you follow this warning.
Occasionally, hypersensitivity reactions have developed in people who restart abacavir after having had a single symptom of those included in the Patient Information Card before they stopped taking it.
Very rarely, patients who have taken medications containing abacavir in the past without symptoms of hypersensitivity have developed a hypersensitivity reaction when restarting it.
If your doctor advises you to restart treatment with Abacavir Tarbis, they may ask you to take the first doses in a place where you have easy access to medical assistance if needed.
If you are hypersensitive to Abacavir Tarbis, you must return all unused Abacavir Tarbis tablets to be safely disposed of. Consult your doctor or pharmacist.
The packaging of Abacavir Tarbis includes a Patient Information Cardto remind you and healthcare personnel about hypersensitivity reactions. Separate the card from the packaging and always carry it with you.

Other Possible Adverse Effects of Combined HIV Treatment
Combined treatments, including Abacavir Tarbis, can cause other diseases to develop during HIV treatment.
Symptoms of Infection and Inflammation
Exacerbation of Old Infections
People with advanced HIV infection (AIDS) have a weakened immune system and are more likely to develop severe infections (opportunistic infections). When these people start treatment, they may find that old infections, which were hidden, flare up, causing signs and symptoms of inflammation. These symptoms are probably due to an improvement in the body's immune response, which allows it to fight these infections. The symptoms usually include fever, plus any of the following:
In rare cases, since the immune system becomes stronger, it can also attack healthy body tissue (autoimmune disorders). The symptoms of autoimmune disorders can appear many months after starting HIV treatment. The symptoms may include:
If you notice any symptoms of infection while taking Abacavir Tarbis:
Tell your doctor immediately. Do not take any other medication for the infection without your doctor's advice.
You may have bone problems
Some patients receiving combined HIV treatment develop a bone disease called osteonecrosis. With this disease, part of the bone tissue dies due to a reduction in blood supply to the bone. People are more likely to suffer from this disease:
Signs of osteonecrosis include:
If you notice any of these symptoms:
Tell your doctor.
