Patient: Hello doctor! Three years ago, my aminotransferase was elevated and I was treated with interferon injections for a year without any effect, then I took lamivudine. She has normal liver function, and also has antibodies and the quantitative test, the antibody count is very high. Yang Yongfeng, Department of Hepatology, Nanjing Second Hospital: Nucleosides have no teratogenic effect in animal experiments, and there are many reports from home and abroad that children born during pregnancy with oral nucleoside drugs are normal. However, there are no large-scale clinical trials to prove the safety of nucleosides on pregnancy. Whether you can have them or not, you need to discuss with your loved ones and decide on the full balance of pros and cons.
