What is Mometasone Aqueous Nasal Spray?
Mometasone furoate, sold under brand names like Nasonex, is a corticosteroid nasal spray used to treat nasal allergy symptoms such as sneezing, itching, and runny nose [1]. It is also used to treat nasal polyps, which are growths in the lining of the nasal passages [1]. The spray delivers the medication directly to the nasal lining [2].
How Does Mometasone Nasal Spray Work?
Mometasone furoate is a topical corticosteroid that works by reducing inflammation in the nasal passages [2]. Inflammation is a key factor in the symptoms of allergic rhinitis and nasal polyps. By suppressing this inflammatory response, the medication alleviates symptoms like congestion, sneezing, and itching [2].
When Does Mometasone Nasal Spray Patent Exclusivity End?
The original patent for mometasone furoate nasal spray has expired, allowing for the introduction of generic versions. For instance, the patent for Nasonex expired in December 2019 [3]. This typically leads to increased competition and lower prices [3].
Can Generic Mometasone Nasal Sprays Be Prescribed?

What Are the Side Effects of Mometasone Nasal Spray?

How Does Mometasone Nasal Spray Compare to Other Allergy Medications?

Other allergy treatments include oral antihistamines, decongestants, leukotriene inhibitors, and immunotherapy (allergy shots or sublingual tablets) [4]. Corticosteroid nasal sprays are generally considered very effective for nasal symptoms [2][4].
