What is PAXLOVID?

What is PAXLOVID?

PAXLOVID is not approved for use as pre-exposure or post-exposure treatment for prevention of COVID-19.

Before taking PAXLOVID, tell your healthcare provider about all of your medical conditions, including if you:

have kidney problems. You may need a different dose or dosing schedule of PAXLOVID.
have liver problems, including hepatitis.
have Human Immunodeficiency Virus 1 (HIV-1) infection. PAXLOVID may lead to some HIV-1 medicines not working as well in the future.
are pregnant or plan to become pregnant. It is not known if PAXLOVID can harm your unborn baby. Tell your healthcare provider right away if you are or if you become pregnant.
are breastfeeding or plan to breastfeed. PAXLOVID can pass into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with PAXLOVID.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Your healthcare provider can tell you if it is safe to take PAXLOVID with other medicines.
You can ask your healthcare provider or pharmacist for a list of medicines that interact with PAXLOVID.
Do not start taking a new medicine without telling your healthcare provider.

Tell your healthcare provider if you are taking combined birth control (hormonal contraceptive). PAXLOVID may affect how your hormonal contraceptives work. Females who are able to become pregnant should use another effective alternative form of contraception or an additional barrier method of contraception during treatment with PAXLOVID. Talk to your healthcare provider if you have any questions about contraceptive methods that might be right for you.
