Abacavir, sold under the brand name Ziagen among others, is a medication used to treat HIV/AIDS.[3][4][5][6] Similar to other nucleoside analog reverse-transcriptase inhibitors (NRTIs), abacavir is used together with other HIV medications, and is not recommended by itself.[7] It is taken by mouth as a tablet or solution and may be used in children over the age of three months.[5][8]

Abacavir is generally well tolerated.[8] Common side effects include vomiting, insomnia (trouble sleeping), fever, and feeling tired.[5] Other common side effects include loss of appetite, headache, nausea (feeling sick), diarrhea, rash, and lethargy (lack of energy).[4] More severe side effects include hypersensitivity, liver damage, and lactic acidosis.[5] Genetic testing can indicate whether a person is at higher risk of developing hypersensitivity.[5] Symptoms of hypersensitivity include rash, vomiting, and shortness of breath.[8] Abacavir is in the NRTI class of medications, which work by blocking reverse transcriptase, an enzyme needed for HIV virus replication.[9] Within the NRTI class, abacavir is a carbocyclic nucleoside.[5]

Abacavir was patented in 1988, and approved for use in the United States in 1998.[10][11] It is on the World Health Organization's List of Essential Medicines.[12] It is available as a generic medication.[5] Abacavir is used together with other HIV medications, such as abacavir/lamivudine/zidovudine, abacavir/dolutegravir/lamivudine, and abacavir/lamivudine.[8][9] The combination abacavir/lamivudine is an essential medicine.[12]
