I’ve Had Gynecomastia — Is Propecia Going to Make it Worse?

Hello Dr.,

I have mild gyno since I was 15, nothing to be worried, just my nipples are larger than those from other guys. Now I’m 21, and I’ve just started using Propecia (2 weeks ago). My questions are:

1. How many are the chances to make even worse my breast condition?
2. When I should see that my gynecomastia is getting worse and what are the signs to alarm me?
3. If it’s getting worse what are the alternatives for me (to save my hair), cause I know propecia is the only DHT blocker approved by the FDA? (I’m a NW2)

1. Your chances of Propecia producing gynecomastia problems is about equal to the regular population (one in about 500 men).
2. If you develop breast enlargement or breast pain, it usually comes on in the first month, but sometimes I have seen it delayed a year or so.
3. There are no FDA approved DHT blockers other than finasteride for treating hair loss. I only recommend FDA approved and proven treatments, which are limited to minoxidil and finasteride at this point.
