Treatment of Season and Perennial Allergic Rhinitis

Intranasal (Adults and Children ≥12 yr) 2 sprays in each nostril once daily (not to exceed 2 sprays in each nostril once daily).
Intranasal (Children 2–11 yr) 1 spray in each nostril once daily.

Prophylaxis of Seasonal Allergic Rhinitis

Intranasal (Adults and Children ≥12 yr) 2 sprays in each nostril once daily initiated 2–4 wk prior to beginning of pollen season.

Treatment of Nasal Polyps

Intranasal (Adults ≥18 yr) 2 sprays in each nostril 1–2 times daily (not to exceed 2 sprays in each nostril twice daily).


Nasal spray: 50 mcg/metered spray in 17-g bottle (delivers 120 sprays)

Nursing implications

Nursing assessment

  • Monitor degree of nasal stuffiness, amount and color of nasal discharge, and frequency of sneezing.
    • Patients on long-term therapy should have periodic otolaryngologic examinations to monitor nasal mucosa and passages for infection or ulceration.
    • Monitor growth rate in children receiving chronic therapy; use lowest possible dose.
  • Lab Test Considerations: Periodic adrenal function tests may be ordered to assess degree of hypothalamic-pituitary-adrenal (HPA) axis suppression in chronic therapy. Children and patients using higher than recommended doses are at highest risk for HPA suppression.

Potential Nursing Diagnoses

Ineffective airway clearance (Indications)
Risk for infection (Side Effects)
Deficient knowledge, related to medication regimen (Patient/Family Teaching)


  • After the desired clinical effect has been obtained, attempts should be made to decrease dose to lowest amount. Gradually decrease dose every 2–4 wk as long as desired effect is maintained. If symptoms return, dose may briefly return to starting dose.
  • Intranasal: Patients also using a nasal decongestant should be given decongestant 5–15 min before glucocorticoid nasal spray.

Patient/Family Teaching

  • Advise patient to take medication exactly as directed. If a dose is missed, take as soon as remembered unless almost time for next dose.
  • Instruct patient in correct technique for administering nasal spray (see ). Shake well before use. Before first-time use, prime unit by spraying 10 times or until fine spray appears. If not used for at least 7 days, reprime by spraying 2 times or until fine spray appears. Prior to administering dose, gently blow nose to clear nostrils. Close 1 nostril. Tilt head forward slightly and insert nasal applicator into other nostril. Spray and breathe inward through nostril. Breathe out through mouth. Repeat procedure in other nostril. Warn patient that temporary nasal stinging may occur.
  • Instruct patient to notify health care professional if symptoms do not improve within 2 wk, or if symptoms worsen.

Evaluation/Desired Outcomes

  • Resolution or prevention of nasal stuffiness, discharge, and sneezing in seasonal or perennial allergic rhinitis or nasal polyps.

It may be worth trying a daily antihistamine, but I suspect you would benefit from steroid nasal drops or a steroid nasal spray such as Beconase, Flixonase or Nasonex.
Nasal sprays (including Flonase, Nasonex and Rhinocort) work by reducing inflammation or as an antihistamine to block the allergic reaction.
Regardless, Leigh Bradshaw, the Pennsylvania academic detailer, sees her competition littered about doctors' offices every day: blue Lunesta clocks and Nasonex tissue boxes.
These generally fall into the categories of 1) the newer, non-sedating antihistamines, such as Allergra, Claritin, Clarinex and Zyrtec and 2) steroid nasal sprays, such as Nasonex, Flonase, and Nasacort.
She recommends over-the-counter Claritin or the prescription antihistamines Zyrtec and Allegra, as well as the nasal steroid sprays Nasonex and Flonase.
