What is the primary treatment for a chronic runny nose?

The primary treatment for a chronic runny nose, often associated with allergic rhinitis or other inflammatory conditions, is intranasal steroids. These medications work by reducing inflammation within the nasal passages, thus alleviating symptoms such as nasal congestion, sneezing, and runny nose. They are particularly effective for addressing the underlying cause of chronic rhinitis, which is often related to allergic triggers or persistent inflammation.

Intranasal steroids act directly at the site of action, providing localized relief without the systemic side effects that can accompany oral medications. They are generally well-tolerated and can lead to significant improvement in symptoms over time with consistent use.

Oral antihistamines can also help with a runny nose, especially if allergies are the primary cause, but they do not address inflammation as effectively as intranasal steroids. Decongestants are more useful for temporary relief of nasal congestion rather than chronic symptoms, and their overuse can lead to rebound congestion. Saline nasal sprays can moisturize nasal passages and temporarily relieve symptoms, but they do not address inflammation or the underlying cause, making them less effective for chronic nasal issues compared to intranasal steroids.
