What is Dovato?

Dovato (dolutegravir and lamivudine) is a combination antiviral medicine that prevents the human immunodeficiency virus (HIV) frommultiplying in your body.

Dovato is used to treat HIV, the virus that can cause the acquired immunodeficiency syndrome (AIDS). This medicine is not a cure for HIV or AIDS.

Dovato is for use only in adults who have not been treated with other antiviral medications in the past.

Important Information

You should not use Dovato if you are also taking dofetilide (Tikosyn).

Taking Dovato during the first trimester of pregnancy may cause birth defects. Use effective birth control to prevent pregnancy while you are using this medicine.

If you've ever had hepatitis B, it may become active or get worse during or after treatment with Dovato. You may need frequent liver function tests for several months.

Before taking this medicine

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:

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.

How should I take Dovato?

Before you start treatment with Dovato, your doctor may perform tests to make sure you do not have hepatitis B.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

You will need frequent medical tests.

If you've ever had hepatitis B, this virus may become active or get worse during treatment with Dovato, or in the months after you stop using this medicine. You may need frequent liver function tests while using Dovato and for several months after your last dose.

Do not change your dose or stop using Dovato without your doctor's advice. Every person with HIV should remain under the care of a doctor.
