Antihistamine sprays (azelastine) block histamine, providing rapid relief from sneezing and itching. Steroid sprays reduce inflammation, helping with congestion and post‑nasal drip. The nasal spray market research shows that antihistamines hold a large share, but nasal steroids are the fastest‑growing therapeutic class, with a CAGR above 8%. Why the surge? Because combination sprays (azelastine + fluticasone) are now available, offering the best of both worlds.
What's the difference? Antihistamines work within 15 minutes, steroids take days. The nasal spray market trends highlight that the fastest‑growing application is allergic rhinitis, driven by climate change (longer pollen seasons) and worsening air pollution.
New options: mast cell stabilisers (cromolyn) that prevent allergy symptoms before they start — great for people who know their triggers.
The bottom line: if you need immediate relief, use an antihistamine. If you have chronic symptoms, use a steroid. And if you can afford it, try a combination spray.
