Women with hepatitis B can still be treated with antiviral medications after pregnancy, but instead of taking interferon, they should use antiviral medications that are less likely to affect the fetus. Hepatitis B is a liver disease caused by hepatitis B virus infection, which affects liver function. Hepatitis B patients need to take reasonable oral anti-hepatitis B virus medication to control the disease. During pregnancy, women can continue to take antiviral drugs to treat the disease. However, women should pay attention to the fact that the anti-hepatitis B virus drugs used during pregnancy should not be interferon, because interferon may cause fetal malformation, and pregnant women are contraindicated. The anti-hepatitis B virus drugs used by women after pregnancy must be strictly in accordance with the doctor’s instructions, under the guidance of the physician to standardize the use of drugs, and individuals must pay attention to the regular examination during the medication. If there are any abnormal adverse reactions after the use of the drug, the physician should be informed in time for treatment.
