. Proactive Medication
- Northern China typically enters peak pollen season in early March. Allergists advise initiating preventive medication 1 week prior to expected exposure.
- Dr. Jiang Zidong (ENT specialist, Peking Union Medical College Hospital) emphasizes: “Early intervention with cromolyn sodium (eye drops/nasal spray) before symptom onset improves efficacy. Delayed treatment after sneezing/rhinitis appears often yields suboptimal results.”
2. Environmental Control
- Indoor spaces:
✓ Regular dusting/mite control essential
✓ Severe cases should use HEPA air purifiers - Vehicles:
✓ Frequently clean car interiors to prevent enclosed allergen accumulation
3. Outdoor Precautions
- High-risk periods: 10:00-17:00 on sunny/windy days
- Protective measures:
✓ Wear N95 masks + wraparound goggles
✓ Post-outdoor decontamination:
• Remove outerwear immediately
• Rinse eyes/nasal passages with saline - Seek urgent care for:
➤ Uncontrolled asthma
➤ Severe conjunctivitis
➤ Persistent rhinorrhea
4. High-Risk Populations
- Children with tic disorders:
✓ Allergy exacerbations may worsen tics
✓ Symptom control requires dual management - First-trimester pregnancies:
✓ Most antihistamines contraindicated
✓ Strategic pregnancy planning advised - Diabetics:
✓ Severe allergies risk fungal rhinosinusitis
✓ Requires immediate ENT intervention
5. Holistic Management
- Maintain psychological well-being
- Stress/anxiety reduction enhances immune resilience
