Read this Medication Guide before you start taking abacavir tablets and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment. Be sure to carry your Abacavir Tablets Warning Card with you at all times.

What is the most important information I should know about abacavir tablets?

1. Serious allergic reaction (hypersensitivity reaction). Abacavir tablets contain abacavir (also contained in EPZICOM®** and TRIZIVIR®**). Patients taking abacavir tablets may have a serious allergic reaction (hypersensitivity reaction) that can cause death. Your risk of this allergic reaction is much higher if you have a gene variation called HLA-B*5701. Your healthcare provider can determine with a blood test if you have this gene variation.

If you get a symptom from two or more of the following groups while taking abacavir tablets, call your healthcare provider right away to find out if you should stop taking abacavir tablets.

Group 1 Fever
Group 2 Rash
Group 3 Nausea, vomiting, diarrhea, abdominal (stomach area) pain
Group 4 Generally ill feeling, extreme tiredness, or achiness
Group 5 Shortness of breath, cough, sore throat


A list of these symptoms is on the Warning Card your pharmacist gives you. Carry this Warning Card with you at all times.

If you stop abacavir tablets because of an allergic reaction, never take abacavir tablets (abacavir sulfate) or any other abacavir-containing medicine (EPZICOM®** and TRIZIVIR®**) again. If you take abacavir tablets or any other abacavir-containing medicine again after you have had an allergic reaction, within hours you may get life threatening symptoms that may include very low blood pressure or death. If you stop abacavir tablets for any other reason, even for a few days, and you are not allergic to abacavir, talk with your healthcare provider before taking it again. Taking abacavir tablets again can 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 abacavir again, start taking it when you are around medical help or people who can call a healthcare provider if you need one.

2. Lactic Acidosis (buildup of acid in the blood). Some human immunodeficiency virus (HIV) medicines, including abacavir tablets, can cause a rare but serious condition called lactic acidosis. Lactic acidosis is a serious medical emergency that can cause death and must be treated in the hospital.

Call your healthcare provider right away if you get any of the following signs or symptoms of lactic acidosis:

3. Serious liver problems. Some people who have taken medicines like abacavir tablets have developed serious liver problems called hepatotoxicity, with liver enlargement (hepatomegaly) and fat in the liver (steatosis). Hepatomegaly with steatosis is a serious medical emergency that can cause death.

Call your healthcare provider right away if you get any of the following signs or symptoms of liver problems:

You may be more likely to get lactic acidosis or serious liver problems if you are female, very overweight, or have been taking nucleoside analogue medicines for a long time.
