Serious Warnings and Precautions
Hepatitis B Infections If you have a hepatitis B infection, you should not stop taking JAMP Abacavir / Lamivudine without instructions from your healthcare professional as your hepatitis may worsen or reoccur. Your healthcare professional will monitor your condition for several months after stopping treatment with JAMP Abacavir / Lamivudine. Hypersensitivity Reaction You should be screened for the HLA-B*5701 gene variation prior to starting or restarting treatment with JAMP Abacavir / Lamivudine, unless you have been screened previously and this is documented. Patients who have the HLA-B*5701 gene variation have a high risk of developing a hypersensitivity reaction (serious allergic reaction) to abacavir, which is in the drug JAMP Abacavir / Lamivudine. This hypersensitivity reaction can be life-threatening if you continue to take JAMP Abacavir / Lamivudine. If you get two or more of the following groups of symptoms while taking JAMP Abacavir / Lamivudine contact your healthcare professional immediately to find out if you should stop taking JAMP Abacavir / Lamivudine: |
|---|
| SYMPTOM(S) | |
|---|---|
| Group 1 | Fever |
| Group 2 | Rash |
| Group 3 | Nausea, vomiting, diarrhea, or abdominal (stomach area) pain |
| Group 4 | Generally ill feeling, extreme tiredness or achiness |
| Group 5 | Shortness of breath, cough or sore throat |
| A list of these symptoms is on the Warning Card provided by your pharmacist. You should |
|---|
carry this Warning Card with you at all times. If you notice these symptoms while taking JAMP Abacavir / Lamivudine, call your healthcare professional immediately. Your healthcare professional may advise you to stop taking JAMP Abacavir / Lamivudine. If you stop JAMP Abacavir / Lamivudine because of a serious allergic reaction, never take JAMP Abacavir / Lamivudine or any other medicine containing abacavir (such as ZIAGEN or TRIUMEQ) again, regardless of whether you have the HLA- B*5701 gene variation or not. Within hours you may experience a life-threatening lowering of your blood pressure or death. If you stop JAMP Abacavir / Lamivudine for any other reason, even for a few days, and you are not allergic to JAMP Abacavir / Lamivudine, talk with your healthcare professional before taking it again. Taking JAMP Abacavir / Lamivudine again may cause a serious allergic or life-threatening reaction, even if you never had an allergic reaction to it before. If your healthcare provider tells you that you can take JAMP Abacavir / Lamivudine, again, start taking it when you are around medical help or people who can call a healthcare professional if you need one. Occasionally, reactions have developed in people who start taking abacavir again, and had only one symptom on the Warning Card before they stopped taking it. If you are hypersensitive to JAMP Abacavir / Lamivudine, return all your unused JAMP Abacavir / Lamivudine tablets for safe disposal. Ask your healthcare professional or pharmacist for advice. |

What is JAMP Abacavir / Lamivudine used for?
JAMP Abacavir / Lamivudine is a medicine used in combination with other antiretrovirals to treat Human Immunodeficiency Virus (HIV) infection.
How does JAMP Abacavir / Lamivudine work?
JAMP Abacavir / Lamivudine contains the active ingredients abacavir sulfate and lamivudine. These belong to a group of antiretroviral medicines called nucleoside analogue reverse transcriptase inhibitors (NRTIs), which are used to treat HIV infection.
JAMP Abacavir / Lamivudine does not cure HIV; it reduces the amount of virus in your body, and keeps it at a low level. It also increases the CD4 cell count in your blood. CD4 cells are a type of white blood cells that are important in helping your body fight infection. You must be sure to be seen regularly by your healthcare provider.
What are the ingredients in JAMP Abacavir / Lamivudine?
Medicinal ingredients: 600 mg of abacavir (as abacavir sulfate) and 300 mg lamivudine.
Non-medicinal ingredients: colloidal silicon dioxide, hypromellose, hydroxypropyl cellulose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80, povidone, sodium starch glycolate, titanium dioxide and FD & C Yellow #6 Aluminum Lake.
JAMP Abacavir / Lamivudine comes in the following dosage forms:
600 mg abacavir / 300 mg lamivudine fixed dose combination tablets.
Do not use JAMP Abacavir / Lamivudine if:
- you previously had an allergic reaction (hypersensitivity) to the active ingredient abacavir, which is also included in medicines called ZIAGEN and TRIUMEQ (see What are the ingredients in JAMP Abacavir / Lamivudine).
- you previously had an allergic reaction to the active ingredient lamivudine which is included in medicines called 3TC, COMBIVIR or any of the other ingredients found in JAMP Abacavir / Lamivudine (see What are the ingredients in JAMP Abacavir / Lamivudine).
- you have the HLA-B* 5701 gene variation.
- you have liver disease.
To help avoid side effects and ensure proper use, talk to your healthcare professional before you take JAMP Abacavir / Lamivudine. Talk about any health conditions or problems you may have, including if you:
- have kidney or liver disease (including hepatitis B or C)
- have previously taken any other NRTI class medicine
- have been tested and know whether or not you have a gene variation called HLA-B*5701
Other warnings you should know about:
JAMP Abacavir / Lamivudine can cause serious side effects, including:
- Lactic Acidosis and Severe Liver Problems: The class of medicines to which JAMP Abacavir / Lamivudine belongs (NRTIs) can cause a condition called lactic acidosis (excess of lactic acid in your blood), together with an enlarged liver. Symptoms of lactic acidosis include feeling of weakness, loss of appetite, sudden unexplained weight loss, upset stomach and difficulty breathing or rapid breathing. This rare, but serious side effect occurs more often in women. If you have liver problems you may also be more at risk of getting this condition.
- Heart Attack: Some HIV medicines including JAMP Abacavir / Lamivudine may increase your risk of heart attack. If you have heart problems, smoke or suffer from diseases that increase your risk of heart disease such as high blood pressure and diabetes, tell your healthcare professional.
- Risk of Infections: You may continue to develop other infections and other illnesses associated with HIV while you are taking JAMP Abacavir / Lamivudine. You should therefore keep in regular contact with your healthcare professional.
Immune Reconstitution Inflammatory Syndrome: Changes to your immune system can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time.
Autoimmune disorders happen when the immune system attacks healthy body tissue. This may happen after you start taking medicines for HIV infection. Examples of this include Grave's disease (which affects the thyroid gland), Guillain-Barré syndrome (which affects the nervous system), polymyositis (which affects the muscles), or autoimmune hepatitis (which affects the liver). Autoimmune disorders may occur many months after the start of treatment.
See the Serious side effects and what to do about them table, below, for more information on these and other serious side effects.
Blood Tests:
Your blood sugar levels (glucose) or level of fats (lipids) in your blood may increase with HIV treatment. Your healthcare professional will decide when to do blood tests, to check for these and other side effects, and will interpret the results.
Pregnancy and Newborns:
If you are pregnant, or planning to become pregnant, talk to your healthcare professional before taking JAMP Abacavir / Lamivudine. It is not known if JAMP Abacavir / Lamivudine is safe to use during pregnancy. Your healthcare professional will decide whether you should continue to take JAMP Abacavir / Lamivudine if you are pregnant. If you are pregnant and taking JAMP Abacavir / Lamivudine to prevent passing HIV to your unborn baby continue to follow your healthcare professionals’ recommendations. If you have questions about the risks to your baby talk to your healthcare professional. If you take JAMP Abacavir / Lamivudine while you are pregnant, talk to your healthcare professional about how you can be included in the Antiretroviral Pregnancy Registry
Babies born to mothers who have taken Nucleoside Reverse Transcriptase Inhibitors (NRTIs) like JAMP Abacavir / Lamivudine during pregnancy or labour have had increased levels of lactate in their blood. The increases are usually temporary. There have also been very rare reports of problems that affect the baby’s nervous system such as delayed development and seizures. The long-term effects of JAMP Abacavir / Lamivudine are not known.
Breastfeeding:
Do not breastfeed while taking JAMP Abacavir / Lamivudine. There is a risk of passing HIV-1 to your baby if you breastfeed. JAMP Abacavir / Lamivudine can also be passed through breast milk and could harm your baby. If you are breastfeeding or planning to breastfeed, talk with your healthcare professional about the best way to feed your baby.
