I am 5 weeks pregnant and was on 50 mg eltroxin for a month(since dec4 2010 to jan 3rd 2011)I had a check of TSH hormone on 3rd.Both T3 and T4 levels were in the normal range.so my physician asked me to reduce the dosage to 25 mg.but my gynaec says that throxine requirement is more during pregnancy..just confused as to wether i should continue with 50 mg or 25 mg?
Hi, The range of TSH to be followed for pregnancy is different from in non-pregnant women. The normal values for first three months of pregnancy is less than 2.5 mid/L, for the last six months of pregnancy is 3.0 mid/L. For, the non-pregnant it is 4.5 mid/L. So everything depends on your present TSH levels if they are below 2.5 then you can take 25 mg of thyroxine, but if they are above 2.5, I would advise you to take 50\u00a0mg. High TSH values have shown to affect the pregnancy, and it is advisable to keep levels in the range described above. Hope this helps. Regards.
