I am going through a rough patch with my asthma again ;-( so using a lot of ventolin. I always try to use a spacer as I know this delivers more medication, plus I just find it easier when I'm struggling. However, if I'm out and about I just use the MDI.
If I use the spacer I get less side effects i.e tremor, heart palpitations even when taking 4-6 puffs, than if I were just to take 2 puffs directly from the MDI. Given the spacer delivers more medication, how come I get less side effects? Any thoughts anyone?
