Can Cromolyn Eye Drops be used with contacts lenses?
Our recommendation is not to use soft contact lenses at all during treatment with Cromolyn, because the preservative (benzalkonium chloride) can discolor the contact lenses. If, however, the patient still wishes to use their contact lenses, they should remove their contact lenses each time they use Cromolyn and wait a minimum of 15 minutes before reinserting the contact lenses.
