To : Ellen Re : Thyroid Scan Have your patient check with the radiologist and see if they can use I-123 instead of I-131. It is actually better as a thyroid scan and the mom would only breifly, if at all, need to discontinue breastfeeding. Check my WEB page for the radioisotope table from the Nuclear Regulatory Commission. It provides good recommendations for radiologists in breastfeeding moms. Regardless, PTU, and Methimazole are both useful for treating hyperthyroidism as long as there are no thyroid carcinomas.
