How nasal sprays and oral antihistamine tablets relieve allergies

Allergies happen when the immune system treats certain harmless substances as allergens, which your body considers a threat.¹ When you’re exposed to these small antigens, your body produces antibodies and histamines, which cause allergic and inflammatory reactions.¹ The result — you guessed it — is nasal allergy congestion and other allergy symptoms.¹

Fortunately, oral antihistamine tablets block histamines and prevent the allergic reaction trigger. Some forms of oral antihistamines include tablets, capsules, gelcaps, chewable tablets, and dissolvable tablets. They primarily relieve seasonal and indoor allergies and help calm the symptoms of hay fever and other allergies such as runny nose, sneezing, itchy, watery eyes, itchy nose, or itchy throat.²

While oral tablets are a great help for allergies, some nasal sprays can target nasal allergy congestion. The U.S. Food and Drug Administration (FDA) approved triamcinolone acetonide, the active ingredient in Nasacort® Allergy 24HR, for over-the-counter (OTC) nasal use to temporarily relieve symptoms of hay fever or other upper respiratory allergies such as nasal congestion, runny nose, sneezing, and itchy nose.

Certain nasal sprays can contain anti-inflammatory medicines that are effective in stopping tough, year-round allergy symptoms.³ Some nasal sprays even work against seasonal allergies and ragweed, the #1 trigger of fall allergies.

When used as directed, Nasacort® Allergy 24HR is an effective nasal spray for year-round nasal allergy symptom relief. As with any medication, if symptoms persist consult your doctor or allergist to make sure nasal sprays are the right solution for you.
