Andrew is 9 and has been on Rhinocort and Zyrtec for about 3 years now. We tried different allergy meds, but zyrtec did the trick. His sinuses are much more clear...they don't get as "sticky" as they used to.
I also wanted to mention that I have had a great experience with our CF / pediatrician team. We recently moved to North Carolina from Michigan, but in Michigan the doc at UM and my family doctor were always in communication so I knew that if there was an issue our family doctor was unsure of, she would check it with our CF doc before prescribing. I felt that between the three of us we had great communication. When we moved 6 months ago everything was new, so I asked our new CF doc, Dr. Davis, (Love Her!), if she could recommend a pediatrician in our area with whom she would have a good working relationship. She gave me a name, we have met him,(love him, too!), and I once again feel that we have a great healthcare team going here.
Sometimes it's up to the patient to facilitate the relationship between care center and family practice. If one or the other is unwilling, I might question why. And, while it's very polite of you to consider how busy your CF center is dealing with CF and not wanting to bother them with other issues,(you sound so sweet!), remember that you are placing your prized possession, your child, under their care! You have the right to ask them any medical question you want.
Good Luck!
