Cases which dropped out of specific immunotherapy using house dust extract for nasal allergy were studied. The rate of dropout of the therapy within a year from the start was 41.6% in 202 cases where the therapy was begun before July 1981, and 32.0% in 75 cases where it was started in 1983. Many of these cases stopped the therapy within 6 months from the start. The rate was lower in the age group of 12 years or less than that of 13 years or more. The rate showed differences by medical institutions where respective patients received therapy. Better nasal conditions were produced in the group that continued than that which dropped out.
