Generic name of nasonex?

What is the generic name of Nasonex?

Nasonex is a brand name for the corticosteroid mometasone furoate (also written as mometasone furoate monohydrate). [1]

Why do people say “mometasone” instead of the full name?

In everyday use, “mometasone” is often used as shorthand for the full generic name mometasone furoate, even though the complete label specifies the furoate form. [1]

Is “Nasonex” only mometasone furoate?

Yes. Nasonex refers to mometasone furoate nasal spray (it is not a different generic drug). [1]
