  • Consultation with a healthcare provider is advised to determine which medication is suitable for your specific needs.

What It Is and How It Works

Nasonex (mometasone furoate) and Nasacort (triamcinolone acetonide) are nasal corticosteroids that work by decreasing inflammation in the nasal passages. This action helps relieve symptoms such as nasal congestion, sneezing, and runny nose associated with allergic rhinitis.
