Whether a hepatitis B patient can get pregnant while taking medication depends largely on the specific medication used. Hepatitis B patients often require antiviral treatment, and currently the first-line antiviral drugs commonly used for chronic hepatitis B include entecavir, tenofovir, adefovir, and other antiviral drugs. Among them, tenofovir is a drug that has been proven to be safe and effective in research and does not affect the fetus, and has been classified as a b-administered drug in pregnancy, so you can get pregnant during the period of medication, but in the case of other antiviral drugs, such as entecavir or adefovir, it is not recommended that you get pregnant during the period of medication in order to avoid any impact on the fetus. Hepatitis B patients who use drugs that can affect the fetus usually need to stop or change the drug before pregnancy, and must be under the guidance of a doctor.
