If you choose not to treat vasomotor rhinitis with over-the-counter or prescription medications, some alternative treatments exist for the condition. You can use a saline solution to rinse out your nasal passages. You can also blow your nose regularly and gently to keep airways free of mucus and irritants. A humidifier a night or at work may help keep the mucus loose and prevent stuffiness. It is also important to drink plenty of fluids and avoid caffeine.
