It’s safe to take in pregnancy

Levothyroxine can be continued during pregnancy without any risks. But during this time, additional monitoring might be conducted. As soon as you become pregnant, your healthcare provider will check your thyroid hormone levels and may adjust your dose during and after your pregnancy. Repeat lab tests should be done after delivery and during each trimester of pregnancy.

Additionally, some people may experience newly discovered hypothyroidism following pregnancy. Starting to take levothyroxine during pregnancy is also safe.
