The aim of this study was to evaluate the effect of levocabastine, a new H 1 ‐blocking antihistamine for topical use, in comparison with sodium cromoglycate on conjunctival symptoms of birch pollinosis. The two drugs were compared in a randomized double‐blind comparative study over 5 weeks in 37 children and adolescents (6–19 years of age) with birch pollen conjuncitivitis. Nasal symptoms occurred in 31 of the children and were treated with beclomethasone dipropionate nasal spray. An oral antihistamine was offered as rescue medication for eye symptoms. Initially, the patients received placebo four times a day for a 7‐day run‐in period. Conjunctival symptoms were recorded daily on diary cards on a 100 mm visual analogue scale. The pollen counts indicated a short but intensive birch pollen season. There was no statistically significant difference between the two treatment groups with regard to eye symptom scores before and during active treatment. However, the patients' evaluation of the efficacy of the therapy was in favour of levocabastine ( P <0.01). Topical levocabastine, an H 1 ‐blocker, applied twice daily, seems to protect from symptoms of allergic conjunctivities as favourably as sodium cromoglycate applied four times a day. There was no difference in number or character of reported adverse reactions between the two treatment groups.
