Thyroiditis

[jill73cats]

dx with hashimoto thyroiditis. Tsh 0.0. Free t4 2.02, free t3 6.7. TPO Ab 73.7.   Iodine uptake 0.8. On low iodine diet   U/s shows lg goiter 6.7 cm each side. .8 mm b/t.  Tachycardia, palps, Sl difficulty swallowing, fatigue, forgetful, hair loss, itchy skin. Endo says try tapazole and atenolol.  Will this work with no uptake?  Still need surgery?  

[Mark Lupo, M.D.]

Tapazole does not work for thyroiditis.  The atenolol is appropriate.
The low uptake on I-123 is consistent with silent thyroiditis (autoimmune, + TPO).
Time is the only treatment, meanwhile use atenolol for the tachycardia and follow thyroid labs about every 4 weeks to see pattern.

Also only 1 small nodule on us 0.6 cm.  No thyroid showed on scan with rai.  I have never taken any thyroid meds. Cutting out sinus meds and caffeine. Had bad leg aches while limiting iodine for a week. Seems odd. Not as bad now. How risky is tapazole
