From the Guidelines
For post-nasal drip, the most effective nasal spray option is fluticasone propionate (Flonase), as it reduces inflammation in the nasal passages that contributes to excess mucus production, according to the study by Zhou 2016 1. The typical dose is 1-2 sprays in each nostril once daily, though you should follow the specific product instructions. For best results, use consistently for several days as the full effect may take time to develop. Before spraying, gently blow your nose and tilt your head slightly forward. Aim the spray toward the outer wall of the nostril, away from the septum. Other helpful options include:
- Saline nasal sprays, which can be used multiple times daily to rinse and moisturize nasal passages.
- Azelastine (Astelin) if allergies are causing your post-nasal drip.
- Oxymetazoline (Afrin) for temporary relief, but not for more than 3 consecutive days to avoid rebound congestion. Post-nasal drip may also improve with:
- Adequate hydration
- Avoiding known allergens
- Using a humidifier It's also important to note that the method of applying saline can affect its effectiveness, with nasal douches being more effective in distributing irrigation solution to the maxillary sinus and frontal recess, as shown in the study by the european position paper on rhinosinusitis and nasal polyps 2020 1. However, the most recent and highest quality study, the european position paper on rhinosinusitis and nasal polyps 2020 1, supports the use of fluticasone propionate (Flonase) as the most effective option for post-nasal drip.
