Call your doctor if you have appetite changes, weight changes, sleep problems (insomnia), and fatigue.

Professional:MONITOR: Androgens may induce reversible clinical hyperthyroidism in patients receiving thyroid hormone replacement therapy. The proposed mechanism is androgen-induced decrease in T4 binding globulin resulting in decreased serum T4, increased T3 uptake resin and free T4, and decreased TSH levels.
MANAGEMENT: Clinical and laboratory monitoring of thyroid function may be necessary, as may a 25% to 50% reduction in thyroid hormone dosage.
