Generic Name: Epzicom (abacavir + lamivudine) Brand Name(s): Generics only. No brands available.


What is Epzicom (Abacavir + Lamivudine) used for?

Epzicom (Abacavir + Lamivudine) is commonly used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Abacavir and lamivudine both belong to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs).

Abacavir/lamivudine is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.

How should I take Epzicom (Abacavir + Lamivudine)?

Take this medication by mouth with or without food, usually once daily or as directed by your doctor.

Because this combination product has fixed doses of abacavir and lamivudine, it should only be used if your doctor has determined that the doses of both medications in this product are right for you.

If you stop taking any medication containing abacavir even for a short time and then restart the drug, you have an increased chance of developing a very serious (possibly fatal) allergic reaction. Refill your medication before you run out. Do not stop treatment unless directed by your doctor. Before restarting any medication containing abacavir, consult your doctor or pharmacist, and be sure you have easy access to medical care.

It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses. Do not increase your dose, take this drug more often than prescribed, or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.

This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same time each day.

How do I store Epzicom (Abacavir + Lamivudine)?

Epzicom (Abacavir + Lamivudine) is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Epzicom (Abacavir + Lamivudine) in the bathroom or the freezer. There may be different brands of Epzicom (Abacavir + Lamivudine) that may have different storage needs.
