in women with known hypothyroidism who become pregnant, it is recommended that serum tsh levels are closely monitored. levothyroxine should be used to keep tsh levels within the normal range for that trimester. the first trimester normal range is below 2.5 miu/l and the second and third trimesters normal range is below 3.0 miu/l. treatment should be guided by total (rather than free) thyroxine or by the free t index. similarly to tsh, the thyroxine results should be interpreted according to the appropriate reference range for that stage of pregnancy. the levothyroxine dose often needs to be increased after pregnancy is confirmed, although this is based on limited evidence and some recommend that it is not always required; decisions may need to based on tsh levels.
