From the Guidelines

The first-line treatment for chronic sinusitis is saline nasal irrigation and topical intranasal corticosteroids, which can be used alone or in combination for symptom relief. This recommendation is based on the most recent and highest quality study available, which suggests that these treatments have a preponderance of benefit over harm 1.

Key Components of Treatment

  • Saline nasal irrigation can be performed using a neti pot or squeeze bottle with sterile or distilled water mixed with salt packets, 1-2 times daily.
  • Topical intranasal corticosteroids, such as fluticasone propionate, mometasone furoate, or budesonide, can be used at 1-2 sprays per nostril once or twice daily for at least 3-6 months.
  • For patients with acute exacerbations or bacterial infections, a 10-14 day course of antibiotics like amoxicillin-clavulanate may be added 1.
  • Oral corticosteroids, such as prednisone, might be prescribed for severe symptoms, but their use should be limited to a short course of 5-7 days at 20-40 mg daily due to potential side effects.

Rationale for Treatment

The goal of treatment for chronic sinusitis is to reduce inflammation, improve mucus drainage, and clear infectious agents. Saline nasal irrigation helps to moisturize the nasal passages and remove debris, while topical intranasal corticosteroids reduce inflammation and swelling. Antibiotics may be necessary for bacterial infections, but their use should be judicious and based on clinical judgment. Oral corticosteroids can be effective for severe symptoms, but their use should be carefully considered due to potential side effects.

Important Considerations

  • Proper technique is crucial for nasal sprays, with patients aiming away from the nasal septum and toward the ear on the same side while gently inhaling.
  • Patients should be educated on the importance of adherence to treatment and follow-up appointments to monitor symptoms and adjust treatment as needed.
  • Referral to a specialist may be necessary for patients with recurrent or chronic symptoms, or those with underlying conditions that complicate treatment, such as nasal polyps or asthma 1.

From the FDA Drug Label

The precise mechanism through which fluticasone propionate affects allergic rhinitis symptoms is not known. Corticosteroids have been shown to have a wide range of effects on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in inflammation.

The first-line treatment for chronic sinusitis is not explicitly stated in the provided drug labels. However, based on the information provided, fluticasone propionate nasal spray may be used to treat symptoms of allergic rhinitis, which can be a contributing factor to chronic sinusitis.

  • The drug label does not provide direct evidence for the use of fluticasone propionate as a first-line treatment for chronic sinusitis.
  • Key points to consider when treating chronic sinusitis include the use of corticosteroids, such as fluticasone propionate, to reduce inflammation and alleviate symptoms. 2

From the Research

First-Line Treatment for Chronic Sinusitis

The first-line treatment for chronic sinusitis typically involves a combination of therapies aimed at reducing inflammation, improving sinus drainage, and eradicating infection. The key components of first-line treatment are:

  • Nasal saline irrigation: High-volume saline irrigation has been shown to improve symptom scores compared to no treatment 3.
  • Topical corticosteroid therapy: Topical corticosteroids have been found to improve overall symptom scores, polyp scores, and reduce polyp recurrence after surgery 3.
  • Additional therapies: Depending on the presence of nasal polyps or other factors, additional therapies such as systemic corticosteroids, oral doxycycline, leukotriene antagonists, or macrolide antibiotics may be considered 3, 4, 5.

Treatment Goals

The primary goals of treatment for chronic sinusitis are to:

  • Enhance mucociliary clearance
  • Improve sinus drainage and outflow
  • Eradicate local infection and inflammation
  • Improve access for topical medications 5

Role of Antibiotics

Antibiotics may be considered in patients with evidence of an active, superimposed acute sinus infection 5, 6. However, the use of antibiotics should be carefully selected and prescribed for an adequate period of time 7, 6.

Referral to Specialists

Patients who do not respond to first-line medical therapy may benefit from referral to an otolaryngologist, allergist, or pulmonologist, especially if there is a history suggestive of other comorbidities 5.
