When you look at the sheer numbers, the Antihistamine Drugs Market is a prime example of the "Democratization of Healthcare." In 2026, the transition of potent antihistamine nasal sprays and tablets from prescription (Rx) to over-the-counter (OTC) status has empowered patients to manage their chronic allergies without a doctor’s visit.

Within the US Antihistamine Drugs Market, this shift has led to massive retail expansion. Major pharmacy chains and big-box retailers are dedicating more shelf space to private-label (generic) versions of popular antihistamines. This increased competition has driven down prices, making daily allergy management more affordable for the average American household while simultaneously increasing the total market volume.
