To the Editor.—
A 68-year-old woman recently started receiving inhaled nebulized cromolyn for chronic asthma and has shown much improvement. The most interesting aspect of its use is that, because she is unable to coordinate exhaling the medication through her mouth, she exhales it through her nose. She reports that for the first time in years she can now breathe through her nose.She had been treated with topical aerosolized steroids for the nasal symptoms, but the treatment was only partially effective. Hence, if it is to be assumed that the beneficial effect on this patient's allergic rhinitis is secondary to the exhaled cromolyn, this would certainly appear to be an effective method of treating both the asthma and allergic rhinitis.
