What are the most effective medical options to help clear and eliminate persistent, white post-viral mucus when there is no cough, especially if previous treatments like montelukast/levocetirizine only temporarily dried up the secretions?
Since you don't have a cough, this mucus is likely pooling from your sinuses. Since antihistamines only provided temporary relief, you might find saline nasal rinses helpful to physically flush out the secretions. Additionally, a generic intranasal corticosteroid spray, like fluticasone, can help reduce localized inflammation in your nasal passages. A generic mucolytic like guaifenesin can also thin the mucus, making it easier to clear. Please stay well-hydrated, and consult a healthcare professional to tailor these options to your needs.
