Dolutegravir/lamivudine/tenofovir (DTG/3TC/TDF) is a fixed-dose combination antiretroviral medication used to treat HIV/AIDS.[1] It is a combination of dolutegravir, lamivudine, and tenofovir disoproxil.[1] As of 2019, it is listed by the World Health Organization (WHO) as the first line treatment for adults, with tenofovir/lamivudine/efavirenz as an alternative.[2] It is taken by mouth.[3]

Side effects may include trouble sleeping, weight gain, and rash.[2][3] While there are concerns that use during pregnancy results in a 0.2% increased risk of neural tube defects in the baby, this does not rule out its use.[2] Use remains recommended after the first trimester.[2] Use is not recommended in those with kidney problems.[3] The combination is a type of antiretroviral therapy.[2]

It is on the World Health Organization's List of Essential Medicines.[4] In some countries it is available as a generic medication.[5] It is tentatively approved in the United States as of 2019, full approval is pending expiration of the US patents on dolutegravir (Tivicay) and tenofovir disoproxil (Viread).[6][7]
