What is the most important information I should know about ZIAGEN?
ZIAGEN can cause serious side effects, including:
- Serious allergic reactions (hypersensitivity reaction) that can cause death have happened with ZIAGEN and other abacavir-containing products. 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.
|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) or any other abacavir-containing medicine (EPZICOM®, TRIUMEQ®, or 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.
- Build-up of acid in your blood (lactic acidosis).
Lactic acidosis can happen in some people who take ZIAGEN. Lactic acidosis is a
serious medical emergency that can cause death. Call your healthcare
provider right away if you get any of the following symptoms that could be
signs of lactic acidosis:
- feel very weak or tired
- unusual (not normal) muscle pain
- trouble breathing
- stomach pain with nausea and vomiting
- feel cold, especially in your arms and legs
- feel dizzy or light-headed
- have a fast or irregular heartbeat
- Serious liver problems can happen in people who
take ZIAGEN. In some cases, these serious liver problems can lead to death.
Your liver may become large (hepatomegaly) and you may develop fat in your
liver (steatosis) when you take ZIAGEN. Call your healthcare provider right
away if you have any of the following signs of liver problems:
- your skin or the white part of your eyes turns yellow (jaundice)
- dark or “tea-colored” urine
- light-colored stools (bowel movements)
- loss of appetite for several days or longer
- pain, aching, or tenderness on the right side of your stomach area
You may be more likely to get lactic acidosis or serious liver problems if you are female, very overweight (obese), or have been taking nucleoside analogue medicines for a long time.
What is ZIAGEN?
ZIAGEN is a prescription HIV-1 (Human Immunodeficiency Virus type 1) medicine used with other antiretroviral medicines to treat HIV-1 infection. HIV-1 is the virus that causes Acquired Immune Deficiency Syndrome (AIDS).
The safety and effectiveness of ZIAGEN has not been established in children under 3 months of age.
When used with other antiretroviral medicines to treat HIV-1 infection, ZIAGEN may help:
- reduce the amount of HIV-1 in your blood. This is called “viral load”.
- increase the number of CD4+ (T) cells in your blood, that help fight off other infections.
Reducing the amount of HIV-1 and increasing the CD4+ (T) cells in your blood may help improve your immune system. This may reduce your risk of death or getting infections that can happen when your immune system is weak (opportunistic infections).
ZIAGEN does not cure HIV-1 infection or AIDS. You must keep taking HIV-1 medicines to control HIV- 1 infection and decrease HIV-related illnesses.
Avoid doing things that can spread HIV-1 infection to others.
- Do not share or re-use needles or other injection equipment.
- Do not share personal items that can have blood or body fluids on them, like toothbrushes and razor blades.
- Do not have any kind of sex without protection. Always practice safer sex by using a latex or polyurethane condom to lower the chance of sexual contact with any body fluids such as semen, vaginal secretions, or blood.
Ask your healthcare provider if you have any questions about how to prevent passing HIV to other people.
