Fluticasone nasal: Various allergens in the air may make you sneeze. If there is nothing new to your environment, it could be seasonal. Long-term, fluticasone nasal spray may help relieve seasonal and year-round allergic nasal symptoms, such as itching and sneezing, as a preventative med. If you provide your allergy meds, there may be other possibilities as well to help you out short-term.
