What is Tivicay?
Tivicay (dolutegravir) is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in your body.
Tivicay is used with other antiviral medications to treat HIV, the virus that can cause the acquired immunodeficiency syndrome (AIDS).
Tivicay is not a cure for HIV or AIDS.
Tivicay is for use in adults and children who weigh at least 66 pounds (30 kilograms).
You should not use Tivicay if you are also taking dofetilide (Tikosyn).
Taking Tivicay during the first trimester of pregnancy may cause birth defects. Use effective birth control to prevent pregnancy while you are using dolutegravir.
Before taking this medicine
You should not use Tivicay if you are allergic to dolutegravir, or if you are also taking dofetilide (Tikosyn).
Tell your doctor if you have ever had:
liver disease, especially hepatitis B or C.
You may need to have a negative pregnancy test before starting treatment with Tivicay.
Tivicay 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 dolutegravir on the baby.
Women with HIV or AIDS should not breast feed 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 Tivicay?
Take Tivicay exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.
You may take Tivicay with or without food.
Dolutegravir doses are based on weight in children. Your child’s dose needs may change if the child gains or loses weight.
While using Tivicay, you may need frequent blood tests.
If you’ve ever had hepatitis B, using dolutegravir can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.
Use all HIV medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor’s advice. Every person with HIV should remain under the care of a doctor.
Store at room temperature away from moisture and heat. Keep the tablets in their original container, along with any packet or canister of moisture-absorbing preservative.
