From the Guidelines
I strongly recommend prescribing guaifenesin for two weeks and increasing Nasacort from once daily to twice daily as needed for this 47-year-old male with chronic nasal congestion. The patient is currently taking Claritin (loratadine) once daily and Nasacort (triamcinolone acetonide) once daily without adequate symptom relief. Guaifenesin is an expectorant that works by thinning mucus secretions, making them easier to clear, which may help relieve the patient's congestion as he has reported previous benefit from this medication 1. Increasing the Nasacort dosage to twice daily can provide enhanced anti-inflammatory effects in the nasal passages, as intranasal corticosteroids reduce inflammation and swelling of nasal tissues.
This combination approach addresses both the mucus production and underlying inflammation contributing to chronic nasal congestion. The use of guaifenesin as an expectorant is supported by studies that show its effectiveness in increasing expectorated sputum volume and decreasing sputum viscosity 1. Although there is limited evidence to support the use of guaifenesin in sinusitis, its use as an expectorant can still provide benefits in relieving nasal congestion.
After two weeks, the patient should be reassessed to determine if this regimen is effective or if further evaluation for other causes of chronic nasal congestion (such as structural abnormalities, chronic sinusitis, or nasal polyps) might be warranted. It is essential to monitor the patient's response to treatment and adjust the regimen as needed to optimize symptom relief and improve quality of life. The patient's report of previous benefit from guaifenesin supports its use in this case, and the addition of increased Nasacort dosage can provide a comprehensive approach to managing chronic nasal congestion 1.

From the Research
Treatment of Chronic Nasal Congestion
- The patient is currently taking Claritin QD and Nasacort QD, and is requesting guaifenesin, which they claim helps a lot 2, 3, 4.
- Increasing Nasacort to BID as needed may be beneficial, as intranasal corticosteroids have been shown to be effective in reducing nasal congestion 2, 5.
- The use of guaifenesin in combination with Nasacort may also be beneficial, as combination therapy with intranasal azelastine and fluticasone propionate has been shown to be effective in treating allergic rhinitis 3, 4.
Efficacy of Intranasal Corticosteroids
- A systematic review and network meta-analysis found that mometasone furoate, fluticasone furoate, and ciclesonide were ranked as the most effective intranasal corticosteroids for treating seasonal allergic rhinitis 5.
- Budesonide was ranked as the most effective intranasal corticosteroid for treating perennial allergic rhinitis 5.
- The efficacy of Nasacort (triamcinolone acetonide) was also evaluated, and was found to be effective in reducing nasal congestion 2, 5.
Combination Therapy
- Combination therapy with intranasal azelastine and fluticasone propionate has been shown to be effective in treating allergic rhinitis, and may be considered as second-line therapy in patients who do not respond to monotherapy 3, 4.
- The use of guaifenesin in combination with Nasacort may also be beneficial, although more research is needed to fully evaluate the efficacy of this combination 2, 3, 4.
