The combination of abacavir, lamivudine, and zidovudine is used, either alone or in combination with other medications, to treat human immunodeficiency virus (HIV) infection. These three drugs belong to a class of medications known as nucleoside reverse transcriptase inhibitors (NRTIs). They work by reducing the amount of HIV in the blood. While this combination does not cure HIV, it can lower the risk of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses, such as serious infections or cancer.

Uses and Dosage

To ensure the best results, take this medication precisely as directed by your doctor. It can be taken by mouth with or without food, typically twice daily. Make sure to consume a full glass of water (8 ounces/240 milliliters) with each dose unless your doctor advises otherwise.

Since this combination product contains fixed doses of abacavir, lamivudine, and zidovudine, it should only be used if your doctor has determined that these doses are appropriate for you.

If you discontinue any medication containing abacavir, even for a short period, and then resume the drug, you have an increased risk of experiencing a severe allergic reaction, which could be fatal. Therefore, ensure you refill your prescription before running out. Do not cease treatment unless instructed by your doctor. Before restarting any medication containing abacavir, consult your doctor or pharmacist, and ensure you have easy access to medical assistance.

Consistency in taking this medication (as well as other HIV medications) exactly as prescribed by your doctor is crucial.

Avoid skipping doses, increasing your dose, taking the drug more frequently than prescribed, or discontinuing it (or other HIV medicines) even temporarily, unless instructed by your doctor. Skipping doses or altering your dosage without your doctor’s approval may lead to increased viral levels, making the infection more challenging to manage (resistant), or exacerbating side effects.

For optimal effectiveness, take this medication at evenly spaced intervals. Establish a routine of taking it at the same times every day to help you remember.
