Short answer: for nose‑heavy allergic rhinitis (especially congestion), intranasal therapies usually relieve symptoms more effectively than oral antihistamines, while pills are a convenient choice for mild or multi‑site symptoms like hives or generalized itch. Multiple trials show sprays outperform pills on total nasal symptom scores and quality of life, with intranasal corticosteroids leading overall and intranasal antihistamines acting fastest. A 2024 meta‑analysis found spray‑based treatments improved nasal outcomes more than oral antihistamines, supporting sprays as first‑line for congestion‑dominant cases (see the 2024 systematic review on PubMed). Combination strategies can bridge gaps when symptoms mix or persist.</p>
