Catacrom 2% Eye Drops Catacrom, Sodium Cromoglicate, in a new single-unit dose format with no added preservatives. Sodium Cromoglicate is a mast cell stabilizer which in eye drop form is the tried & tested 'first line' treatment for allergic eye disease. Catacrom offers this established therapy with the additional advantage that symptoms will not be exacerbated by preservatives which are often used in multi-dose formats. Catacrom has been introduced to coincide with the hay fever season. However it has the added benefit of helping the many people who suffer with all year round (perennial) allergic conjunctivitis brought on by house dust mites, pet fur & even allergic reactions from contact with substances such as cosmetics. Catacrom is equally effective as a prophylaxis, but treatment should be started before the patient is exposed to the allergen. It has minimal side effects & is suitable to be used by children, as well as users of gas permeable & rigid contact lenses.
