## Q&A

**Q: What is Resdung in clinical terms?**  
A: Resdung is the commonly used local Malaysian term for allergic rhinitis, an IgE-mediated inflammatory response of the nasal mucosa triggered by environmental particles like dust mites, pet dander, and fungal spores.

**Q: How can one distinguish Resdung from an infectious cold?**  
A: Resdung presents with clear watery nasal discharge, paroxysmal morning sneezing, and itchy palate or eyes without fever. A cold usually includes throat soreness, fever, malaise, and thicker colored mucus.

**Q: What over-the-counter pharmacy treatments are used for Resdung in Malaysia?**  
A: Common pharmacy options include non-drowsy second-generation oral antihistamines (such as cetirizine or loratadine), intranasal corticosteroid sprays, and isotonic saline nasal washes to mechanically flush allergens.

**Q: Why does the Malaysian climate exacerbate Resdung flare-ups?**  
A: Malaysia's year-round warmth and high relative humidity create optimal conditions for house dust mite proliferation and indoor mold spores, which Dr.Ann identifies as primary triggers for chronic allergic rhinitis.

**Q: What safety precautions should be taken before using pharmacy remedies for Resdung?**  
A: Always verify correct dosage and contraindications with a certified pharmacist or medical practitioner. *This information is for reference only and does not replace professional medical advice; consult a doctor before use.*
