Is Gynecomastia (Male Breasts) a Side Effect of Hair Loss Drug Rogaine (Minoxidil)?

Does minoxidil cause [tag]gynecomastia[/tag] (male breast development)? How about additional facial hair?

There is a lot of misinformation and confusion regarding medical [tag]hair loss[/tag] treatments on the Internet. Side effects of [tag]Propecia[/tag] ([tag]finasteride[/tag]) and [tag]Rogaine[/tag] ([tag]minoxidil[/tag]) sometimes become confused. While gynecomastia is a known side effect of Propecia, it is not associated with minoxidil use.

Increased facial hair is a documented side effect of Rogaine. Other common side effects are scalp irritation, itching and redness. Less common side effects are low blood pressure, abnormal heart rhythm and dizziness.
