When should I start using Cromolyn?
The best results are obtained when you start to use Cromolyn before the onset of seasonal allergy symptoms. Start using Cromolyn approximately one week before the allergy season begins and continue to use it every day throughout the allergy season, even if you do not have any symptoms. You can also use Cromolyn to relieve your signs and symptoms after seasonal allergies have begun and to prevent further symptoms from appearing.
