I have had asthma since I was about 12, but was actaully diagnosed when I was 15. Mine is almost exclusively allergy induced. I have *horrid* allergies, but I resist taking meds (for both conditions) due to nursing.
I am currently on Zyrtec-D for allergies and I use a very, very small dose albuterol via nebulizer when needed. I have found that when I keep my allergies under control, my asthma is pretty much under control. I have an asthmacort inhaler as well, but it makes my blood pressure bottom out for a few seconds and I nearly blacked out a couple of times, so I dont take it often.
We took out all of our carpet and rugs, no pets, and are careful about foods, weather and pollens. Beds ahve non-allergen bedding and we use an air-contitioner to keep the bedroom cool (too hot, and I have trouble breathing.)
Aidan has resp. problems as well, which is one reason why we are nursing for so long... He uses a Xopenex neb. about 5x a week.
My *worst* attack ever was when I was about 7m preg with Aidan... I should have gone to the hospital, but didnt... DH was scared... he called my parents to come over (they live next door) at 2AM. My lips were blue, and I was so sick feeling! That was brought on by contractions and stress... Luckily, a few puffs on my rescue inhaler was enough to clear my lungs, but talk about a wake-up call! I definetly keep track of my meds better now.
I really need to go have another allergy test done, and then when my babies are weaned, I will be able to take a stronger allergy scrip.
