Does taking letrozole tablets during pregnancy affect the baby's health?

Patient's question:

No

Doctor's answer:

Letrozole tablets are contraindicated during pregnancy and have an impact on the fetus. If you are already pregnant, it is recommended to undergo prenatal examinations. Perform a Down syndrome screening between weeks 14-19 of pregnancy. At week 20, choose a suitable hospital to establish a prenatal examination card and conduct regular prenatal examinations. After establishing the prenatal examination card, you will generally have an examination every four weeks before week 36 of pregnancy, and once after week 36, you will have an examination every week. If any discomfort occurs during this process, you can visit a doctor at any time to increase the frequency of examinations.
