It is indicated in the treatment of AIDS/HIV-1.[2] For this purpose, the combination is very useful in pregnant women to decrease the risk of mother-to-child transmission.[6]

The most common effects include headache and nausea (feeling sick).[3]

Abacavir/lamivudine/zidovudine was approved for use in the United States and the European Union in 2000.[7][3] In December 2013, Lupin Limited launched a generic version of abacavir/lamivudine/zidovudine.[8][9][10]

Side effectsEdit

The most common side effects of abacavir/lamivudine/zidovudine include nausea, vomiting, diarrhea, fatigue, paresthesia and headache. As with many medications targeting reverse transcriptase, body fat redistribution syndrome may occur, causing body fat to center on the upper back and neck, breast, and torso, and potentially decreasing around the legs, arms, and face.[11] IRIS may occur which is when the immune system initially improves, but then deteriorates as a previously ignored infection becomes active. Other serious side effects include:[12]
