Can Cromolyn be used year-round?
Patients can safely use Cromolyn throughout the peak seasonal allergy periods each year. It is not recommended for year-round use, as there is always the chance that you may become tolerant to the medication through over-use. If you use it all year-round, Cromolyn may stop working for you. Taking a break from Cromolyn during the non-allergy season will avoid this risk and the product should be effective when used during the following allergy season.
