What you think of my prognosis if my labs are like this tsh0.025 frm 0.013 nd ft3 4.82 frm 6.10 after taking methimazole for 21dys but im on ptu (propylthiouracil) now?

Getting better: It takes many weeks (typically 6 weeks) for Methimazole or ptu (propylthiouracil) to bring thyroid levels down to normal. The TSH will remain low even after your thyroid level is normal, because it takes time for the pituitary gland to recover from the high levels. At this time, just follow the thyroid level and remain on medication. ...Read more

I have hyperthyroidism. Is taking ptu (propylthiouracil) ok in pregnancy?

Category "D": Ptu (propylthiouracil) works by preventing a final stage of thyroid hormone assembly in the gland. The fetal gland is generally finished forming by 11wks, & they begin to make their own hormone. While most would avoid ptu (propylthiouracil) after 11 wks, it is a better choice for early pregnancy than some alternatives. You need to discuss your pregnancy concerns with your dr & come up with a plan that works for u & baby. ...Read more
