Hi jshet, no problem at all! I am starting Cayston in an effort to improve FEV1. I rarely have to be admitted to hospital due to new infections (2x in 29 years), but I'm at 31% FEV1, so my doctor is doing all he can to keep me away from a transplant for as long as possible. I was admitted last year (that was one of the 2x I've been admitted) for an aggressive IV antibiotic treatment, but my FEV1 did not improve. Now we're trying this.
As a side note, I was diagnosed at 15 and am now 29. FEV1 has ALWAYS been between 40% and 30%. But the last few years it's been 35%, 34%, 33%, 32% and the last one 31%. The decline is very slow but gradual.
Good luck to you and your son. I can update this post with my progress after I've been on Cayston for 6 weeks. (I will go in for a lung function test 6 weeks in to see how it's going)
