Understanding Sneezing Attacks: Causes, Symptoms & Relief

A sneezing attack (paroxysmal sneezing) is a burst of repetitive, involuntary sneezes triggered by nasal irritation. While usually benign, it can be disruptive.

Common Triggers

• Allergens: Pollen, dust mites, pet dander, mold spores (allergic rhinitis).
• Infections: Viral URI (common cold, flu), sinusitis — post-nasal drip tickles nasal mucosa.
• Non-Allergic Rhinitis: Temperature change (cold air), strong odors (perfume, smoke), spicy food (gustatory rhinitis), bright light (photic sneeze reflex/ACHOO syndrome — 18–35% of population).
• Irritants: Chemical fumes, pollution, pepper, dust.
• Structural: Nasal polyps, deviated septum.
• Medications: ACE inhibitors (cough → sneeze), NSAIDs (in aspirin-exacerbated respiratory disease).

Physiology

1. Trigger: Irritation of nasal trigeminal nerve endings.
2. Afferent: Via ophthalmic/maxillary branches → "sneeze center" in lateral medulla.
3. Efferent: Coordinated motor output: deep inspiration (diaphragm, intercostals) → glottis closure → pressure buildup → explosive expiration (glottis opens, velum depresses) → high-velocity air/mucus expulsion (up to 100 mph).
4. Refractory Period: Brief inhibition prevents immediate re-triggering; attacks overcome this.

Management

• Identify & Avoid Triggers: Allergy testing, environmental control.
• Intranasal Corticosteroids: First-line for allergic rhinitis (fluticasone, mometasone).
• Antihistamines: 2nd gen (cetirizine, fexofenadine, loratadine) — less sedation.
• Intranasal Antihistamines: Azelastine, olopatadine — rapid onset.
• Saline Irrigation: Clears irritants, mucus.
• Anticholinergic (Ipratropium): For rhinorrhea-driven sneeze.
• Immunotherapy: SCIT/SLIT for confirmed allergies.

When to See a Doctor

• Attacks frequent, severe, disruptive.
• Associated: epistaxis, facial pain, anosmia, vision changes, neurologic symptoms.
• OTC treatments ineffective after 2–4 weeks.
