I understand how frustrating it is to rely on Allegra every night just to get a good night's sleep. For long-term relief from these nighttime allergy symptoms, we can look beyond daily antihistamines. First, addressing indoor triggers like dust mites by using allergen-proof mattress covers and HEPA filters can make a big difference. Professionally, a daily generic nasal corticosteroid spray (like fluticasone) is often more effective for nasal congestion and is safe for ongoing use. For a permanent solution, I highly recommend consulting an allergist. They can perform allergy testing and discuss allergen immunotherapy (allergy shots or drops), which helps your body build a lasting tolerance to your triggers.
