Most of the time their is no immediate reaction. I have been on it for a long time. After taking it a few days my eyes quit watering as much and my nose quit running, also helped my eyes and nose quit itching. If it is causing any other kind of response such as breathing problems or severe itching u may be allergic and need to see a Dr.
