  • Subjects that immunotherapy may be an absolute contraindication according to the criteria of the immunotherapy Committee of the Spanish society of Allergy and Clinical Immunology, and of the European Allergy and Clinical Immunology Immunotherapy Subcommittee may also include.
  • Subjects with important symptoms of rhinoconjunctivitis /bronchial asthma in which the suspension of the systemic antihistamine treatment is contraindicated.
  • Subjects with persistent severe or not controlled asthma , with a forced expiratory volume (FEV) < 70 respect to the reference value in spite of the appropriate pharmacological treatment at the time of the inclusion in the trial.
