MEDICATION GUIDE

ZIAGEN ® (ZY-uh- jen)

(abacavir sulfate)

Tablets and Oral Solution

Read this Medication Guide before you start taking ZIAGEN 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 ZIAGEN Warning Card with you at all times.

What is the most important information I should know about ZIAGEN?

1.Serious allergic reaction (hypersensitivity reaction). ZIAGEN contains abacavir (also contained in EPZICOM ® and TRIZIVIR ®). Patients taking ZIAGEN 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 2 or more of the following groups while taking ZIAGEN, call your healthcare provider right away to find out if you should stop taking ZIAGEN.

	Symptom(s)
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 ZIAGEN because of an allergic reaction, never take ZIAGEN (abacavir sulfate) or any other abacavir-containing medicine (EPZICOM and TRIZIVIR) again. If you take ZIAGEN 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 ZIAGEN, for any other reason, even for a few days, and you are not allergic to ZIAGEN, talk with your healthcare provider before taking it again. Taking ZIAGEN 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 ZIAGEN 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 ZIAGEN, 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:

• you feel very weak or tired
• you have unusual (not normal) muscle pain
• you have trouble breathing
• you have stomach pain with nausea and vomiting
• you feel cold, especially in your arms and legs
• you feel dizzy or light-headed
• you have a fast or irregular heartbeat

3. Serious liver problems. Some people who have taken medicines like ZIAGEN 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:

• your skin or the white part of your eyes turns yellow (jaundice)
• your urine turns dark
• your bowel movements (stools) turn light in color
• you don’t feel like eating food for several days or longer
• you feel sick to your stomach (nausea)
• you have lower stomach area (abdominal) pain

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.

What is ZIAGEN?

ZIAGEN is a prescription medicine used to treat HIV infection. ZIAGEN is a medicine called a nucleoside analogue reverse transcriptase inhibitor (NRTI). ZIAGEN is always used with other anti-HIV medicines. When used in combination with these other medicines, ZIAGEN helps lower the amount of HIV in your blood.

• ZIAGEN does not cure HIV infection or AIDS.
• It is not known if ZIAGEN will help you live longer or have fewer of the medical problems that people get with HIV or AIDS.
• It is very important that you see your doctor regularly while you are taking ZIAGEN.

Who should not take ZIAGEN?

Do not take ZIAGEN if you:

• are allergic to abacavir or any of the ingredients in ZIAGEN. See the end of this Medication Guide for a complete list of ingredients in ZIAGEN.
• have certain liver problems.

What should I tell my healthcare provider before taking ZIAGEN?

Before you take ZIAGEN, tell your healthcare provider if you:

• have been tested and know whether or not you have a particular gene variation called HLA-B*5701.
• have hepatitis B virus infection or have other liver problems.
• have heart problems, smoke, or have diseases that increase your risk of heart disease such as high blood pressure, high cholesterol, or diabetes.
• are pregnant or plan to become pregnant. It is not known if ZIAGEN will harm your unborn baby. Talk to your healthcare provider if you are pregnant or plan to become pregnant.
  Pregnancy Registry. If you take ZIAGEN while you are pregnant, talk to your healthcare provider about how you can take part in the Pregnancy Registry for ZIAGEN. The purpose of the pregnancy registry is to collect information about the health of you and your baby.
• are breastfeeding or plan to breastfeed. Do not breastfeed. We do not know if ZIAGEN can be passed to your baby in your breast milk and whether it could harm your baby. Also, mothers with HIV-1 should not breastfeed because HIV-1 can be passed to the baby in the breast milk.

Tell your healthcare provider about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Especially tell your healthcare provider if you take:

• alcohol
• methadone
• TRIZIVIR (abacavir sulfate, lamivudine, and zidovudine)
• EPZICOM (abacavir sulfate and lamivudine)

Ask your healthcare provider if you are not sure if you take one of the medicines listed above.

ZIAGEN may affect the way other medicines work, and other medicines may affect how ZIAGEN works.

  If you stop your anti-HIV medicines, even for a short time, the amount of virus in your blood may increase and the virus may become harder to treat. If you take too much ZIAGEN, call your healthcare provider or poison control center or go to the nearest hospital emergency room right away.

What are the possible side effects of ZIAGEN?

• ZIAGEN can cause serious side effects including allergic reactions, lactic acidosis, and liver problems. See “What is the most important information I should know about ZIAGEN?”

 These changes may include:
