What side effects are there to using Rogaine?
The most common side effect of Rogaine is simple itching. In some people this can be a simple irritation, in others it can be an allergic reaction. A small percentage of people experience dizziness and/or shortness of breath. These are because Minoxidil lowers blood pressure, and too much is being absorbed and causing your blood pressure to drop. If you know you have low blood pressure already, be very careful using Minoxidil. Some people also get a bitter taste in their mouth after application.
