Abacavir/lamivudine, sold under the brand name Kivexa among others, is a fixed-dose combination antiretroviral medication used to treat HIV/AIDS. It contains abacavir and lamivudine. It is generally recommended for use with other antiretrovirals. It is commonly used as part of the preferred treatment in children.[3] It is taken by mouth as a tablet.[4]
Common side effects include trouble sleeping, headache, depression, feeling tired, nausea, rash, and fever.[4] Serious side effects may include high blood lactate levels, allergic reactions, and enlargement of the liver.[4] It is not recommended in people with a specific gene known as HLA-B*5701.[4] Safety in pregnancy has not been well studied but it appears to be okay.[5] Lamivudine and abacavir are both nucleoside reverse transcriptase inhibitors (NRTI).[4]
Abacavir/lamivudine was approved for medical use in the United States in 2004.[4] It is on the World Health Organization's List of Essential Medicines.[6]
