Pirinase goes further than antihistamine tablets* to relieve hayfever symptoms including nasal congestion. Pirinase is a nasal spray which helps provide relief for the symptoms of hayfever where they start.
Hayfever is triggered by your body's reaction to airborne allergens, such as pollen. The reaction involves the release of numerous inflammatory substances, such as histamine, chemokines, leukotrienes, cytokines, tryptases and prostaglandins.
It's these substances which cause your hayfever symptoms including the uncomfortable blocked nose, sneezing and the irritating itchy and watery eyes. Pirinase helps block these 6 substances.
*vs. single ingredient antihistamine which do not treat nasal congestion.
