What is post-nasal drip?
Post-nasal drip is the sensation of mucus dripping from the nose into the throat. The mucus is normal — the perception is heightened. Causes include allergies, sinusitis, reflux (laryngopharyngeal reflux), non-allergic rhinitis, smoke/irritants.
Treatment requires identifying the underlying cause. Common triggers respond to intranasal steroids, antihistamines, or reflux treatment.
Do I have post-nasal drip? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Allergic rhinitis (seasonal or perennial), chronic sinusitis, non-allergic rhinitis (vasomotor), GERD/LPR (laryngopharyngeal reflux), pregnancy hormones, certain medications, dry air, deviated septum.
Is it contagious?
Depends on cause.
Reflux-driven post-nasal drip is wildly under-recognized — many cases that fail standard nasal treatment are actually GERD in disguise.
Can it be treated online?
Post-nasal drip is well-suited to telehealth. Chronic symptoms not responding to standard treatment, hoarseness >3 weeks, weight loss, or red flags need in-person ENT.
How post-nasal drip is treated
Treat underlying cause. Allergic: intranasal steroids (fluticasone, mometasone), antihistamines. Chronic sinusitis: intranasal steroids, saline irrigation, sometimes antibiotics. LPR (reflux): PPI, lifestyle changes. Non-allergic vasomotor: intranasal ipratropium, intranasal steroids. Irritants: avoid triggers. Saline nasal irrigation helps almost all causes.
Self-care while you wait
- Saline nasal rinse (NeilMed, Navage) once or twice daily
- Stay hydrated — thins mucus
- Humidifier
- Identify allergens or triggers
- Elevate head of bed if reflux suspected
- Avoid dairy if it worsens for you
- Limit alcohol and smoke
- Treat allergies aggressively
How long does it last?
Depends on cause. Acute: days to weeks. Chronic: ongoing management.
Frequently asked questions
Why is it worse at night?
Lying flat allows mucus to pool in back of throat. Elevating head helps.
Will dairy cause more mucus?
Doesn't actually increase mucus production but can thicken sensation in some. Trial avoidance if you notice connection.
Should I use Sudafed long-term?
Oral decongestants are short-term only. Long-term raises BP and disturbs sleep. Intranasal steroids are better long-term.
Is throat clearing damaging my voice?
Yes — chronic throat clearing irritates vocal cords. Try sipping water instead.
Can it be from anxiety?
Anxiety doesn't cause it, but heightened awareness of throat sensations can amplify symptoms.
