Nasal Irrigation for Runny Nose and Nasal Congestion
Nasal saline irrigation is effective for relieving runny nose and nasal congestion symptoms by thinning mucus, removing inflammatory proteins, and flushing out irritants and bacteria from the nasal and sinus cavities. 1
How Nasal Irrigation Works
Nasal irrigation provides several therapeutic benefits:
- Thins and removes mucus
- Clears proteins that cause inflammation
- Flushes out irritants and bacteria
- Improves mucociliary function
- Decreases nasal mucosal edema 1, 2
Evidence-Based Recommendations
Type of Solution
- Isotonic saline (0.9%) or Ringer's lactate solution is recommended for nasal irrigation 1
- Hypertonic saline (3-5%) may have superior anti-inflammatory effects in some cases but can cause more irritation 1
- Evidence does not consistently show hypertonic saline to be more effective than isotonic saline 1
Delivery Method
- Both low-volume nasal sprays and high-volume irrigation devices (squeeze bottles, neti pots) are effective 1
- While high-volume irrigation may distribute solution more effectively throughout the nasal cavity, studies have not consistently shown superior symptom improvement compared to nasal sprays 1
Frequency
- For acute symptoms: Use 2-4 times daily until symptoms improve
- For chronic conditions: Regular daily use is recommended 2
Clinical Evidence of Effectiveness
Research demonstrates that nasal saline irrigation:
- Reduces patient-reported disease severity compared to no irrigation for up to three months 3
- Improves symptoms in patients with various nasal conditions including allergic rhinitis and rhinosinusitis 4
- Provides significant improvement in 23 of 30 nasal symptoms in patients with sinonasal disease 4
Practical Considerations
Proper Technique
- Lean over sink with head tilted to one side
- Direct solution away from the nasal septum
- Allow solution to flow through one nostril and out the other
- Repeat on opposite side
- Gently blow nose afterward to clear remaining solution 2
Potential Side Effects
- Side effects are generally minor and can include:
- Local irritation
- Ear pain
- Nasal burning
- Occasional nosebleeds 1
- These can often be avoided by adjusting technique or salinity 5
What to Avoid
- Baby shampoo additives (can cause congestion and smell loss) 1
- Contaminated irrigation devices (clean regularly) 2
- Prolonged use of nasal decongestants (can cause rebound congestion) 6
Special Considerations
- For patients with allergic rhinitis, combining nasal irrigation with intranasal corticosteroids may provide better symptom control 7
- For chronic rhinosinusitis, nasal irrigation is considered an important aspect of treatment 1
- Patients with recurrent acute rhinosinusitis may benefit from regular irrigation as preventive therapy 1
Bottom Line
Nasal saline irrigation is a safe, effective, and well-supported treatment for nasal congestion and runny nose. It works best when used regularly with proper technique and appropriate solutions. While it may not completely eliminate symptoms in all cases, it significantly improves quality of life and may reduce reliance on medications for many patients.

For patients with persistent symptoms despite nasal irrigation, consider adding intranasal corticosteroids, particularly for those with allergic rhinitis or chronic rhinosinusitis 2, 7.
