Epzicom

Generic Name: abacavir/lamivudine (a-BAK-a-vir/la-MIV-ue-deen)
Brand Name: Epzicom

Epzicom has caused severe and sometimes fatal allergic reactions. Contact your doctor right away if you develop fever; rash; nausea, vomiting, diarrhea, or stomach pain; cough, sore throat, or trouble breathing; unusual tiredness or achiness; or general feeling of being unwell. Do NOT take Epzicom again or take any other medicine that contains abacavir if you have had an allergic reaction to Epzicom. You may be at risk for an even more severe allergic reaction. If you stop taking Epzicom for any other reason, even for a few days, and you are not allergic to it, check with your doctor before restarting it.

Patients who have a certain gene type called HLA-B*5701 have an increased risk of having an allergic reaction to abacavir. A lab test may be performed before you start Epzicom to see if you have this gene type. Discuss any questions or concerns with your doctor.

High levels of lactic acid in the blood (lactic acidosis) and severe liver problems, including fatal cases, have been reported in patients taking certain HIV medicines, such as Epzicom. The risk may be greater in women, in patients who are very overweight, or in patients who have a history of liver problems. It may also be increased in patients who have taken certain HIV medicines for a prolonged period of time. Tell your doctor immediately if you have dark urine; fast or irregular heartbeat; pale stools; rapid or difficult breathing; severe or unusual drowsiness, dizziness, or light-headedness; sluggishness; stomach pain (with or without nausea or vomiting); unusual muscle pain or tenderness; unusual tiredness or weakness; or yellowing of the eyes and skin. Contact your doctor right away if you start to feel unusually cold, especially in your arms and legs, or if you have a general feeling of being unwell.

Severe worsening of hepatitis B virus (HBV) has been reported in patients who have both HIV and HBV infection and have stopped taking lamivudine. Patients who have both HIV and HBV infection need close medical follow-up to check for worsening liver problems for at least several months after stopping lamivudine. Be sure to keep all doctor and lab appointments.

This may not be a complete list of all interactions that may occur. Ask your health care provider if Epzicom may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use Epzicom:

Use Epzicom as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Epzicom comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Epzicom refilled.
  • Epzicom comes with a warning card that provides information about recognition of allergic reactions. Carry the warning card of allergy symptoms with you. Tell your health care provider immediately about any side effects you experience while taking Epzicom.
  • Take Epzicom by mouth with or without food.
  • Taking Epzicom at the same time each day will help you remember to take it.
  • Take Epzicom on a regular schedule to get the most benefit from it.
  • Continue to take Epzicom even if you feel well. Do not miss any doses.
  • If you miss a dose of Epzicom, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Epzicom.

Important safety information:

  • Epzicom may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Epzicom with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • Tell your doctor or dentist that you take Epzicom before you receive any medical or dental care, emergency care, or surgery.
  • Drinking alcohol while taking Epzicom may cause an increased risk of side effects. Talk to your doctor before drinking alcohol while you are taking Epzicom.
  • Epzicom is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
  • When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Epzicom, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
  • If you stop taking Epzicom even for a few days (eg, if you run out of your medicine and do not get it refilled right away), contact your doctor before you start taking it again. You may experience a serious allergic reaction if you stop taking Epzicom and then start again.
  • Epzicom does not stop the spread of HIV to others through blood or sexual contact. Do not have any kind of sex without protection (eg, latex or polyurethane condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors. Talk with your health care provider about ways to prevent the spread of HIV to others.
  • Epzicom may improve immune system function. This may reveal hidden infections in some patients. Tell your doctor right away if you notice symptoms of infection (eg, fever, sore throat, weakness, cough, shortness of breath) after you start Epzicom.
  • Changes in body fat (eg, an increased amount of fat in the upper back, neck, breast, and trunk, and loss of fat from the legs, arms, and face) may occur in some patients taking Epzicom. The cause and long-term effects of these changes are unknown. Discuss any concerns with your doctor.
  • Diabetes patients - Epzicom may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
  • Patients who have a certain gene type called HLA-B*5701 have an increased risk of a severe or even fatal allergic reaction to Epzicom. A lab test may be performed before you start Epzicom to see if you have this gene type. Discuss any questions or concerns with your doctor.
  • Lab tests, including CD4 counts, complete blood cell counts, and liver function, may be performed while you use Epzicom. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Epzicom should not be used in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of taking Epzicom while you are pregnant. Epzicom is found in breast milk. Do not breast-feed while taking Epzicom. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or Epzicom to the baby.
