Is there a rebound effect when a patient stops using Cromolyn?
Since sodium cromoglycate is not a decongestant, there is no rebound effect after the treatment is discontinued. However, we recommended that you discontinue the productgradually, over a period of one week, rather than abruptly, to avoid the reappearance of symptoms if the allergen is still present. It is sometimes hard to tell when to stop using Cromolyn, since the product stops symptoms before they start. Discontinuing slowly will allow you to detect the return of symptoms early on, so that you can start taking regular doses again to head them off.
