Am I causing harm to the 8wk old fetus by continuing to take ptu (propylthiouracil) if my TSH is 0.10 and my free T4 is 1.4?

Dose adjusted. During pregnancy, your thyroid activity can fluctuate and has to be adjusted by your md. It does cross the placenta and affect the fetus, hence dose adjustment necessary. On the other hand if you stop your medicine, you can encounter severe problems to you and your fetus and worst is thyroid storm. So talk to your md and leave the adjustment to them, please.

I have primary hyperthyroidism. My T4 level is 23 but my TSH levels are 0.01. How long does it take for levels to rise. Currently taking 100mg ptu (propylthiouracil) dai?

Hyperthyroid. The PTH will lower your T4 and you will start to feel better. TSH is the pituitary hormone that controls the thyroid. If your T4 has been elevated for a while, your pituitary TSH will take a while to recover and may not start to elevate right away. But do not obsess about this. Your FT4 of 23 is in the upper range of normal, I believe. This is perhaps why your doc gave you a low dose of PTU (propylthiouracil). Read more...
