All my children were premature, I had my oldest who is 20yrs when I was 5 months pregnant and she has asthma, my 10 yr old was born at 7 months and has asthma, and our youngest who is 10 months old and has Ichthyosis also has asthma, which they found when he came down with RSV. He also was a preemie. We were told that Ashthma goes along with Ichthyosis. Basically they said if you have Ichthyosis you will have Asthma. But I am sure there are more experienced people on the boards in regards to this.
When he needs it we hook him up to the neubulizer and put a presription medicine in it called Xopenex(spelling?) and it works great.
