Chronic nasal congestion due to rhinitis. are saline nasal sprays effective in the long term? congestion will come back if stopped? thanks.

Lots of Options: OTC non-sedating antihistamines like Allegra, Claritin, (loratadine) or Zyrtec are helpful for perennial allergic rhinitis symptoms, however the gold-standard treatment are daily intranasal steroid sprays if your symptoms are more severe. Avoidance of triggers is important as well and allergy shots are also an option. Saline sprays are useful but will not provide lasting relief used alone. See Allergist.
