Blood work did not reveal any endocrine abnormality to explain symptoms
-blood count, kidney function, liver enzymes are in the normal range
- thyroid function, prolactin, testosterone, cortisol in the normal range
-growth hormone normal range
-breast ultrasound, showed benign gynecomastia ( enlarged breast tissue)
Most providers prescribed tamoxifen over raloxifene, because there is not a lot of data with raloxifene.
So can try 3 month trial of tamoxifen 10 mg twice daily to see whether improvement of symptoms
tamoxifen can decrease glandular tissue, but it does not always resulte in complete resolution of the gynecomastia
This is a non FDA indication for tamoxifen
Adverse events in men taking tamoxifen are rare, but include epigastric distress and possible increase risk for blood clots in lower extremity or lung.
So
Tamoxifen 10 mg twice daily for 3 months, follow up with endocrinology in 3 months
Repeat thyroid function test in 6 months ( TSH was in the upper range of normal)
