Hepatitis B patients can take birth control pills, and birth control pills have no special effects on hepatitis B patients. If you take birth control pills because you are afraid to have a baby because you have hepatitis B, birth control is not recommended. Because even if a pregnant woman carries hepatitis B virus, the success rate of mother-to-child blocking treatment is relatively high, so she can have a normal pregnancy. If you are afraid that your newborn will be infected with the hepatitis B virus, you can undergo mother-to-child interruption of treatment (MTCT) at the time of birth, and the success rate of MTCT is currently reported to be up to 95%. The regimen for PMTCT is anti-hepatitis B immunoglobulin and hepatitis B vaccine, but it is important to administer the vaccine as early as possible, preferably within 24 hours of the birth of the newborn. The other 5% may have contracted the hepatitis B virus internally, and for double insurance the pregnant woman can be given oral tenofovir to address the problem of the fetus being infected internally.
