Read the Medication Guide that comes with Ziagen before you start taking it and each time you get a refill because there may be new information. This information does not take the place of talking to your doctor 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?
Serious Allergic Reaction to Abacavir. Ziagen contains abacavir (also contained in EpzicomTM and Trizivir®). Patients taking Ziagen may have a serious allergic reaction (hypersensitivity reaction) that can cause death. If you get a symptom from 2 or more of the following groups while taking Ziagen, stop taking Ziagen and call your doctor right away.
-
- 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
If you stop treatment with Ziagen because of this serious reaction, NEVER take Ziagen (abacavir) 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 doctor 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 doctor tells you that you can take Ziagen again, start taking it when you are around medical help or people who can call a doctor if you need one.
Lactic Acidosis. Some HIV medicines, including Ziagen, can cause a rare but serious condition called lactic acidosis with liver enlargement (hepatomegaly). Nausea and tiredness that donít get better may be symptoms of lactic acidosis. In some cases this condition can cause death. Women, overweight people, and people who have taken HIV medicines like Ziagen for a long time have a higher chance of getting lactic acidosis and liver enlargement. Lactic acidosis is a medical emergency and must be treated in the hospital.
Ziagen can have other serious side effects. Be sure to read the section below entitled "What are the possible side effects of Ziagen?"
What is Ziagen?
Ziagen is a prescription medicine used to treat HIV infection. Ziagen is taken by mouth as a tablet or a strawberry-banana-flavored liquid. 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 found in your blood. This helps to keep your immune system as healthy as possible so that it can help fight infection.
Different combinations of medicines are used to treat HIV infection. You and your doctor should discuss which combination of medicines is best for you.
- Ziagen does not cure HIV infection or AIDS. We do not know 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.
- Ziagen does not lower the risk of passing HIV to other people through sexual contact, sharing needles, or being exposed to your blood. For your health and the health of others, it is important to always practice safe sex by using a latex or polyurethane condom or other barrier method to lower the chance of sexual contact with semen, vaginal secretions, or blood. Never use or share dirty needles.
Ziagen has not been studied in children under 3 months of age or in adults over 65 years of age.
