Question 54 · LEK · Hyperthyroidism
A 66-year-old male patient with an attack of atrial fibrillation has TSH 0.1 mlU/L (N 0.27 - 4.2) and FT4 1.98 ng/dL (N 0.7-1.7). The patient has been taking 100 µg of thyroxine once a day because he was diagnosed with hypothyroidism three years ago. Indicate the optimal treatment of thyroid disease:
- A. reduce the dose of thyroxine to 75 µg/day and check TSH in 4-6 weeks.
- B. totally stop thyroxine and check TSH in three days.
- C. totally stop thyroxine and check TSH in three months.
- D. start to implement thyrostatic treatment.
- E. refer the patient to radioiodine treatment.
Hint
Low TSH with high FT4 in a patient on levothyroxine for hypothyroidism points to iatrogenic excess, not a new thyroid disease.
