Allergies > Cromones
Cromones are taken as nose or eye solutions. They can be used to treat mild allergic rhinitis symptoms. They work by blocking the release of inflammatory substances that cause allergic rhinitis.
They are generally less effective than antihistamines and topical steroids. They also need to be applied regularly. However, cromones have virtually no side effects.
Cromones may be useful in people that cannot use antihistamines. When taken before the start of the pollen season, they may be helpful in reducing allergic symptoms during the pollen season.
