May depress the formation, release, and activity of endogenous chemical mediators of inflammation (kinins, histamine, liposomal enzymes, prostaglandins). Leukocytes and macrophages may have to be present for the initiation of responses mediated by the above substances. Inhibits the margination and subsequent cell migration to the area of injury, and also reverses the dilatation and increased vessel permeability in the area resulting in decreased access of cells to the sites of injury.

Off Label Uses
Rhinosinusitis, adjunctive treatment (acute)
Based on the Infectious Diseases Society of America (IDSA) guidelines for acute bacterial rhinosinusitis (ABRS) in children and adults and the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNS) guidelines for adult sinusitis, mometasone (nasal), among other intranasal corticosteroids, is effective and recommended as an adjunctive treatment to antibiotic therapy for the management of ABRS primarily when a history of allergic rhinitis exists (according to IDSA guidelines).
Rhinosinusitis, treatment (acute, mild to moderate, uncomplicated)
Data from a randomized, double-blind, double-dummy, placebo-controlled study supports the use of intranasal mometasone in the treatment of acute, uncomplicated rhinosinusitis. Intranasal mometasone was more effective than placebo or amoxicillin in reducing major symptom scores. Symptomatic improvement occurred as early as day 2 of mometasone treatment [Meltzer 2005]. Additional trials may be necessary to further define the role of intranasal mometasone in this condition.
Based on the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNS) guidelines for adult sinusitis, mometasone (nasal), among other intranasal corticosteroids, is effective and recommended (with or without nasal saline irrigation) for the symptomatic relief of chronic rhinosinusitis.
Hypersensitivity to mometasone or any component of the formulation.
Documentation of allergenic cross-reactivity for corticosteroids is limited. However, the possibility of cross-sensitivity cannot be ruled out with certainty because of similarities in chemical structure and/or pharmacologic actions.

Dosing: Renal Impairment
There are no dosage adjustments provided in the manufacturer’s labeling (has not been studied)
Dosing: Hepatic Impairment
There are no dosage adjustments provided in the manufacturer’s labeling; drug accumulation may increase with severity of hepatic impairment.
For intranasal administration only. Prime pump (press 10 times or until fine spray appears) prior to first use. If 7 or more days have elapsed since last use, reprime pump with 2 sprays or until a fine mist appears. Shake before using. Blow nose to clear nostrils. Insert applicator into nostril, tilt head slightly forward keeping bottle upright, and close off the other nostril. Breathe in through nose. While inhaling, press pump to release spray; exhale through mouth. After each use, wipe the spray tip with a clean tissue and replace cap. Avoid spraying directly into nasal septum, eyes or mouth. Discard after 120 medicated sprays have been used, even if bottle is not completely empty.
Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Protect from light.

Concerns related to adverse effects:
• Adrenal suppression: When recommended doses are exceeded, or in extremely sensitive individuals, may cause hypercortisolism or suppression of hypothalamic-pituitary-adrenal (HPA) axis. Reports consistent with hypercortisolism are rare. HPA axis suppression may lead to adrenal crisis. Withdrawal and discontinuation of a corticosteroid should be done slowly and carefully. Fatalities have occurred due to adrenal insufficiency in asthmatic patients during and after transfer from systemic corticosteroids to aerosol steroids; aerosol steroids do not provide the systemic steroid needed to treat patients having trauma, surgery, or infections.
• Delayed wound healing: Avoid nasal corticosteroid use in patients with recent nasal septal ulcers, nasal surgery, or nasal trauma until healing has occurred.
• Hypersensitivity reactions: Hypersensitivity reactions including wheezing have been reported; discontinue if such reactions occur.
• Immunosuppression: Prolonged use of corticosteroids may also increase the incidence of secondary infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to vaccines. Avoid exposure to chickenpox and/or measles, especially if not immunized.
• Local nasal effects: Nasal septum perforation, epistaxis and localized Candida albicans infections of the nose and/or pharynx may occur. Periodically examine nasal mucosa in patients on long term therapy; discontinuation of therapy may be necessary if an infection occurs.
• Hepatic impairment: Use with caution in patients with hepatic impairment: drug accumulation may increase with severity of hepatic impairment.
• Infections: Use caution or avoid in patients with active or latent tuberculosis or in patients with untreated fungal, bacterial, systemic viral infections, or ocular herpes simplex; worsening of these conditions may occur. Do not use in untreated localized infection involving the nasal mucosa; concurrent antimicrobial therapy should be administered if bacterial infection of the sinuses is suspected/confirmed.
• Ocular disease: Use with caution in patients with cataracts and/or glaucoma; increased intraocular pressure, glaucoma, and cataracts have occurred with prolonged use. Consider routine eye exams in chronic users or in patients who report visual changes.
• Pediatric: Avoid using higher than recommended dosages; suppression of linear growth (ie, reduction of growth velocity), reduced bone mineral density, or hypercortisolism (Cushing syndrome) may occur; titrate to lowest effective dose. Reduction in growth velocity may occur when corticosteroids are administered to pediatric patients, even at recommended doses via intranasal route (monitor growth).
• Appropriate use: Prior to use, the dose and duration of treatment should be based on the risk vs benefit for each individual patient. In general, use the smallest effective dose for the shortest duration of time to minimize adverse events. A gradual tapering of dose may be required prior to discontinuing therapy. There have been reports of systemic corticosteroid withdrawal symptoms (eg, joint/muscle pain, lassitude, depression) when withdrawing inhalation therapy.
Growth (adolescents and children); signs/symptoms of HPA axis suppression/adrenal insufficiency; glaucoma and/or cataracts especially in patients with a change in vision; adverse nasal effects (eg, nasal septal perforation, nasal ulceration, epistaxis, localized Candida albicans infections).
Pregnancy Risk Factor
Adverse events have been observed in some animal reproduction studies.
Intranasal corticosteroids, including mometasone, may be acceptable for the treatment of rhinitis during pregnancy when used at recommended doses (Lal 2016; Wallace 2008). Pregnant women adequately controlled on mometasone may continue therapy; if initiating treatment during pregnancy, use of an agent with more data in pregnant women may be preferred (Namazy 2016; Wallace 2008).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache, cough, muscle pain, sinus pain, or pharyngitis. Have patient report immediately to prescriber signs of infection, signs of adrenal gland problems (severe nausea, vomiting, severe dizziness, passing out, muscle weakness, severe fatigue, mood changes, lack of appetite, or weight loss), severe rhinitis, severe nosebleed, nasal sores, wheezing, thrush, painful periods, or vision changes (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
