It’s a substance that triggers an allergic reaction.

Here’s a list of the most common triggers of both indoor and outdoor allergies:

Full prescription strength available OTC

No matter what you’re currently taking to relieve your nasal allergy symptoms, this is good news. Because you get full prescription-strength 24-hour scent-free and alcohol-free relief for all nasal allergy symptoms—without a prescription.

Nasacort, part of the most effective class of medicine for the treatment of nasal allergy symptoms, is the first made available right at the shelf, over the counter. No visits to your doctor are necessary.

Stops more of what makes you miserable.

When you encounter allergens like pollen and pet dander, your body creates a variety of chemical responses that can make you feel miserable. Antihistamines target only one of these responses. Nasacort stops more. It blocks more of your body's chemical responses to indoor and outdoor allergens.

As a result, it reduces inflammation and relieves the worst nasal allergy symptoms, even congestion, for 24 hours.

Scent- and alcohol-free. Non-addictive

If you haven’t tried a nasal spray in a while, now’s the time. Unlike OTC decongestant sprays, Nasacort is non-addictive. And, unlike Flonase, it's also scent-free and alcohol-free.

Plus, unlike sedating allergy medicines you may have tried, it comes with no warnings about drowsiness on the label. And you can use it in conjunction with blood pressure medicines.
