Usage of Dovato

Dovato is a combination antiviral medicine that prevents the human immunodeficiency virus (HIV) from multiplying in your body.

Dovato is used without other HIV-1 medicines to treat HIV-1 infection in adults:

who have not received HIV-1 medicines in the past, or

to replace their current HIV-1 medicines when their healthcare provider determines that they meet certain requirements.

Before taking Dovato

You should not use Dovato if you are allergic to dolutegravir or lamivudine, or if you are also taking dofetilide (Tikosyn).

To make sure Dovato is safe for you, tell your doctor if you have ever had:

kidney problems; or

liver disease, especially hepatitis B or C.

You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, if you are overweight, or if you are a woman. Ask your doctor about your risk.

You may need to have a negative pregnancy test before starting treatment with Dovato.

Dolutegravir and lamivudine may harm an unborn baby if you take the medicine at the time of conception or during the first 12 weeks of pregnancy. Use effective birth control to prevent pregnancy, and tell your doctor if you become pregnant.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of Dovato on the baby.

Women with HIV or AIDS should not breastfeed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
