For a dust allergy, non-drowsy antihistamines like Cetirizine, Loratadine, or Fexofenadine are highly effective for relieving sneezing, itching, and a runny nose. If you experience nasal congestion, a steroid nasal spray like Fluticasone (Flonase) can significantly reduce inflammation. For severe symptoms, a doctor may prescribe stronger medications or recommend immunotherapy (allergy shots). Please consult a healthcare professional before starting any new medication to ensure it is safe for you, especially if you have other medical conditions.
