Irrigation therapy is recommended for washing the nasal cavity in treatment of respiratory illness, allergy and sinusitis in further cases.

Initiate Symptomatic Treatment (obstructive symptoms due to non-allergic rhinitis): Nasal saline irrigation. Nasal saline irrigation can be purchased over the counter.

Adjunctive Therapy: Use of isotonic saline or hypertonic saline to irrigate the sinuses is now recommended as adjunct therapy with antibiotics. Saline spray also can be used, especially for children who are likely to find irrigation objectionable. Oral decongestants, topical decongestants and antihistamines are not recommended as adjunctive therapy.

Allergy Self-Care Measures: Nasal saline irrigation.

Sinus Infection Self-Care Measures: Nasal saline irrigation (saline nasal drops, spray to thin mucus).
