Great idea. But i wouldn't want to try it outside of a clinical trial.
Don't do it. Tamoxifen is an anti estrogen prescribed for hormonal dependent breast cancer in females also for prevention of breast cancer. I am not aware of the use of tamoxifen in males. Most gynecomastias are caused by medications. Simply lowering the dosis or stopping them there will be improvement. Tamoxifen is indicated for mastalgia ( not gynecomastia) in females but not in males.
Probably not. It is an anti-estrogen drug which may keep the condition from getting worse, but it probably won't reverse it.
Yes. Although tamoxifen is not fda-approved for this use, multiple studies have been published demonstrating it's benefit treating gynecomastia. It is probably most beneficial early in the development of the disease. If no effect is seen after three months, continuing the drug further is probably not helpful. Read more...
