I also have a history of having Gynecomastia when I was 15, and it was surgically removed. Will my risk be high if I start Finasteride?
Before staring the drug Finasteride, I always perform a HAIRCHECK, which accurately shows the amount of hair lost at the time the drug is started. If no hair is lost, I advise against the drug.
However, if hair is lost, then I remeasure the patient one year later to see what happened to the balding process and if the drug (1) was started, and (2) the value and the benefit, if any, of taking the drug. For young men with a history of Gynecomastia, the drug Finasteride is not any more of a risk in your situation compared to other men of your age.
