Whether taking tenofovir can prepare for pregnancy, also need to combine with the patient’s liver function, hepatitis B markers, hepatitis B virus DNA load and other indicators to determine, if the indicators are not fully controlled is not recommended to prepare for pregnancy, if the indicators are well controlled, the drug does not affect the preparation for pregnancy and pregnancy. Tenofovir is a commonly used antiviral drug for the treatment of hepatitis B. If the patient’s liver function, hepatitis B markers, hepatitis B DNA load and other indicators are abnormal, it suggests that hepatitis B disease is poorly controlled, and the probability of mother-to-child transmission of hepatitis B after pregnancy is high, which can easily exacerbate the disease, so it is not recommended to prepare for pregnancy. According to the U.S. Food and Drug Administration’s Pregnancy Drug Safety Classification System, tenofovir is class B. No adverse effects of the drug on animal fetuses have been found, and no birth defects higher than those in the general population have been found in babies born during pregnancy treated with tenofovir, so if hepatitis B is well controlled, the use of tenofovir does not affect the preparation for pregnancy and pregnancy. Whether or not you can get pregnant on tenofovir also depends on the indicators of hepatitis B. It is recommended that you consult your doctor for advice, and you should take regular checkups to reduce the risk of disease when you get pregnant.
