Question on Exercise-Induced Wheezing

Q: My 14-year-old daughter wheezes when she exercises, so our family doctor prescribed her a salbutamol inhaler to use to relieve the wheezing. Is that appropriate or should she be on a daily medication?

Dr. Watson: Exercise-induced wheezing is a sign of asthma. It was appropriate for your family doctor to prescribe a “reliever” inhaler such as salbutamol to help with her symptoms.

She should use this reliever inhaler prior to any vigorous activity, plus as needed to treat any wheezing symptoms afterwards. But monitoring how often she has symptoms and needs the reliever inhaler will be important in determining whether there is a next step.

If she uses it four or more times per week to prevent or treat exercise-induced symptoms, or more than three times a month for night-time symptoms, then she likely ought to be using a controller medication.

These medications include inhaled corticosteroids and oral leukotriene receptor antagonists, both of which are safe and can be very effective to control asthma symptoms so that the reliever inhaler is not needed regularly.
