Biktarvy and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Biktarvy falls into category B. There are no well-done studies that have been done in humans with Biktarvy. This medication has been evaluated in a limited number of women during pregnancy and postpartum. Human and animal data suggest that Biktarvy does not increase the risk of major birth defects overall. However, there are no well controlled studies in pregnant women. Biktarvy should be during pregnancy only if clearly needed.

If you use Biktarvy while you are pregnant, talk to your doctor about how you can be on the Antiviral Pregnancy Registry.

 

Biktarvy and Lactation

Tell your doctor if you are breastfeeding. You should not breastfeed if you are HIV-positive because of the chance of passing the HIV virus to your baby.

Also, it is not known if Biktarvy can pass into your breast milk and if it can harm your baby. If you are a woman who has or will have a baby, talk with your doctor about the best way to feed your baby.

Biktarvy Usage

Take Biktarvy exactly as prescribed. Biktarvy comes in an oral tablet form and is taken once daily with or without food. 

You should take Biktarvy at the same time each day to help you to remember your dose.

If you miss a dose, take it as soon as you remember that day. Do not take 2 doses of Biktarvy in one day. Do not skip doses.

If you stop taking Biktarvy, even for a short time, the amount of virus in your blood may increase. The virus may become harder to treat.
