    Endo said to get blood test before taking daily Synthroid

    My 15-year-old son has Hashimoto's, so he gets periodic labs to make sure his Synthroid dose is correct. For the last labs, his endocrinologist told me to make sure he had his blood drawn before, or else four hours after, his daily Synthroid dose.

    Has anyone heard of this before? My daughter and I are also on Synthroid, and our endocrinologists never mentioned this to us.

    That's right. The rush of T4 from the pill into the blood before it reaches cells can deceptively appear as an excessive dose and can cause a clueless MD to inappropriately and unnecessarily reduce that dose.
