Abstract:
A 29-year-old female patient took vitamins with minerals tablets (29) (each tablet contains 150 μg of iodine) for nearly one year because she was preparing for pregnancy. Abnormal thyroid function was found in pre-pregnancy examination. Her free thyroxine (FT 4) was 23.2 pmol/L, free triiodothyronine (FT 3) was 5.56 pmol/L, and thyroid stimulating hormone (TSH) was 0.10 mU/L. According to the doctor′s advice, she stopped taking vitamins with minerals tablets (29) immediately. Five days after discontinuation of the drug, her FT 4 was 21.2 pmol/L, FT 3 was 5.39 pmol/L, TSH was 0.08 mU/L, and thyrotropin receptor antibody was <0.3 U/L. The results of re-examination on day 59 after drug withdrawal showed FT 4 16.35 pmol/L, FT 3 4.97 pmol/L, and TSH 2.36 mU/L. It was considered that the patient′s thyroid dysfunction was caused by vitamins with minerals tablets (29).
