Dosage Of Medication To Control TSH Levels During Second Trimester?
Hi.. I am pregnant, now I am in 12th week. When I was 6 weeks I got to know that I have TSH level of 11.5. Then doctor prescribed 50 mcg of Thyronorm. Now end of 11th week I checke dit again and TSH has come down to 1.5. But doctor increased the dosage to 75 mcg, saying that in second trimester I need more and TSH may increase again. Is it alright to take 75 mcg though the TSH is 1.5 during second trimetser of pregnancy?

Dear kalpana,
Untreated hypothyroidism in early pregnancy may cause-
1. abortion
2. still birth
3. pre mature baby
4. subnormal mental development of the baby
as well as chances of anaemia and bleeding in mother also increases.
Ideally treatment should start with 100mcg and then increase 5 mcg per 2 weeks depending upon TSH and T4 level.
However you have not mentioned your T4 level here.
Anyway it is quite safe to take 75 mcg because TSH level may rise again and then it will affect the fetus. So dont worry. Just check the TSH and T4 every month.
best of luck.

Hi,
Though requirement of thyronorm increases in second trimester, your TSH level appears well controlled. Its OK to increase the dose, otherwise second option is to monitor TSH 4 weekly & increase only if TSH goes above 2.5-3.0. Your doctor might have considered other factors which we are not knowing, so you can safely increase dose to 75. But just don't forget to keep monitoring TSH levels.
Wish you good health.

Hi,
There is no need to increase the dosage of thyronorm when the TSH levels are on the lower side and there are no anti-thyroid antibodies or symptoms of hypothyroidism as this could lead to hyperthyroidism. It is true that at the onset of pregnancy the dosage can be increased by 50% to compensate for the increased demand. The dosage should be adjusted by periodic checking of the TSH levels. Please consult an endocrinologist and take further advice. Good luck.
