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

Abacavir is generally well tolerated. Common side effects include vomiting, trouble sleeping, fever, and feeling tired. More severe side effects include hypersensitivity, liver damage, and lactic acidosis. Genetic testing can indicate whether a person is at higher risk of developing hypersensitivity. Symptoms of hypersensitivity include rash, vomiting, and shortness of breath. Abacavir is in the NRTI class of medications, which work by blocking reverse transcriptase, an enzyme needed for HIV virus replication. Within the NRTI class, abacavir is a carbocyclic nucleoside.

Abacavir was patented in 1988, and approved for use in the United States in 1998. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. The wholesale cost in the developing world as of 2014 is between US$0.36 and US$0.83 per day. As of 2016 the wholesale cost for a typical month of medication in the United States is US$70.50. Commonly, abacavir is sold together with other HIV medications, such as abacavir/lamivudine/zidovudine, abacavir/dolutegravir/lamivudine, and abacavir/lamivudine. The combination abacavir/lamivudine is also an essential medicine.
