###Human: What medicine can be used for allergic reaction to dust? ###Assistant: Hello. I suggest you investigate with AEC (absolute eosinophil count) testing so that further comment can be given. If AEC is much high, Hetrazan can be prescribed. For allergy inflammation, Fexofenadine plus Montelukast combination can be prescribed. Moreover, for rhinitis, Azelestin or Fluticasone nasal spray can be prescribed to use for 3 to 5 days. Steam inhalation done three times a day with lukewarm water will be beneficial. I would like to suggest you consult an otorhinolaryngologist for detailed evaluation as rhinitis is there for one month.
