Nasacort (triamcinolone) or flonaise, what is better for treating nasal allergies?

Roughly Equal: Either of these sprays are fine for allergies. They both work the same way. Nasacort (triamcinolone) is available over the counter which means you do not need a prescription. It is also scent and alcohol free so it is easier on the nose. Flonase is very effective, but does contain alcohol and some scent which does irritate some noses.
