Nasonex (Mometasone) is a nasal corticosteroid that works directly on nasal tissue to reduce swelling and inflammation. The medication is used to treat itching, runny nose, postnasal drip, nasal congestion and sneezing in people with a history of rhinitis. Shake gently before each use. Before using the medication for the first time, the unit must be "primed" with 3 to 4 pumps of the spray. Do not use more than two sprays in each nostril daily.

SIDE EFFECTS: The more common side effects are nose bleeding, blood in nasal mucus, or nasal burning or irritation. Less common or rare occurrences are headache, sneezing, runny nose, nasal dryness, congestion, or stomach upset.
