The high rate of limited efficacy reported for treatment with OTC medication, combined with the frequency of year-round allergy problems, points to a need for improvements in therapy and strategies to encourage individuals to take advantage of existing therapeutic options that may improve their quality of life, Gomes said.
The survey results also indicated that multiple allergies were common, Schoemmell said. The data showed that 90% of respondents had nasal symptoms as well as allergic conjunctivitis, while 40% reported a skin allergy, 16% a drug allergy, and 9% a food allergy; 15% had asthma.
The survey also was designed to explore an overlap between ocular allergy and dry eye, with 48% of respondents reported symptoms of dry eye along with conjunctivitis. However, only 31% were using artificial tears to treat dry eye, and 69% who said they do not use do, however, have the desire to use them.
Data of this sort would be important in designing clinical trials to document the extent of this overlap and develop treatment strategies, Gomes said.
