Sharon:
What is your regimen? That is, how many puffs of ventilin and far in advance of a match/any cardio? The typical dosage is 2 puffs, 60 seconds apart, 20 minues before any cardio. If you are not doing it that way, it may be the cause for your attack. My doctor has told me not to use again more than 2 hours later if at all possible. I've been jogging for years doing this and have no problems. I am on a daily preventer also.
