A 39-year-old Caucasian female with a diagnosis of allergic rhinitis and asthma for 20 years is
referred for evaluation to the allergy clinic. She was on Advair 250/50 bid
(fluticasone/salmeterol) for two years, approximately four years ago, and then Advair was stopped
by by her pulmonologist because her pulmonary function tests were normal. She is here for
evaluation of allergic rhinitis by skin prick testing. She has increased shortness of breath with
exercise. She reports loss of voice, cough, and shortness of breath when eating or laughing. The
symptoms occur throughout the year. She also reports nasal congestion and for that, she takes
Allegra D QAM and Allegra QPM . She rates the nasal symptoms as 5 out of 10 on a zero to 10 scale,
when she is off the medication, and down to 1 to 2 out of 10 when she takes Allegra D. She also
reports dry cough for 20 years which does not respond to albuterol. She exercises daily and uses
albuterol 30 to 60 minutes before exercise, and then during her exercise routine for cough, change
in her voice and shortness of breath. Thealbuterol helps, but it does not relieve her symptoms
completely. She was on intranasal steroids in the past, but the spray was used inconsistently and
she does not recall the effect of this treatment.
