Subjects will be given the option to participate for Phase 2 of the study. In this phase, subjects will continue on either placebo or active product throughout the next pollen season, starting in January 2008, and fill out Rhinitis Quality of Life Questionnaires when they pick up the study tablets at the beginning of April, May and June. They will be asked to fill out daily medication/symptom diaries during the first two weeks of May (exact dates subject to change depending on climatic factors). The peak grass pollen season is April through June. Blood will be drawn at a last visit in late June 2008 for specific and total IgE by ImmunoCAP.
