Dark Circles Under My Eyes While Taking Propecia

Dr. Rassman,
I took Propecia for two years and had seen great results with my hair loss when I began to notice dark circles around my eyes. This made me stop taking the drug three months ago, and the dark circles have virtually disappeared. However, immediately after stopping to take the drug I developed puffy nipples and I can actually feel the enlarged glands under my nipples. I’ve read about gynecomastia and Propecia, but the side effects seem to appear when taking the drug, and not after stopping it. I wonder if you might have any insight on the matter. I’m hoping that this is my body’s reaction to the hormonal change and that over time my nipples will return to normal (there’s no fat accumulation, only gland enlargement).
Thank You

I highly doubt that dark circles under your eyes are from Propecia and this is not a reported known side effect. It may be a coincidence or the fact that you were tired and not getting enough rest, so look for external causes of dark circles.

Gynecomastia is one of the rare side effects of Propecia, but you are correct in stating that it occurs while you are using it (not stopping it). You need to see a doctor for further evaluation and physical examination. Gynecomastia is often the result of hormone manipulation. Are you taking steroids?
