My lifeís totally dependent on Ventolin, in various forms, since I was 18 months old. In fact, I was one of those tested for Ventolinís effectiveness among young children. It has certainly held the thread of my life! I never had any single side effect from its use for the last nineteen years. Except when I had potentially scary asthma attacks, it always brings immediate comfort. The only issue I had with it is inhaling it to my lungs when my lungs can only take 50% less than what it is supposed to be.
