Uses for Mometasone Furoate
Mometasone Furoate Dosage and Administration
For therapeutic effectiveness, use at regular intervals.1
Shake inhaler gently immediately prior to use.1
Prior to initial use, the metered-dose pump spray must be primed with 10 actuations or until a fine spray appears.1 b Prime pump after a period of nonuse (i.e., >1 week) by actuating twice or until a fine spray appears.1 b c
Clear nasal passages prior to administration.b
Tilt the head slightly forward, insert the nasal applicator into one nostril, b and point the tip of the applicator away from the nasal septum.b Pump the drug into the nostrilb while holding the other nostril closed and concurrently inspiring through the nose.b Repeat procedure for the other nostril.b
Clean nasal applicator by removing the nasal applicator and plastic cap.c Soak the nasal applicator in cold tap water and/or rinse in warm water and dry.c Rinse the plastic cap under cold water and dry.c Reassemble the nasal applicator with the pump by reinserting the pump stem into the center opening of the applicator.c Reprime the pump by actuating twice or until a fine spray appears.c
Available as mometasone furoate monohydrate; dosage expressed in terms of anhydrous mometasone furoate.1
After priming, nasal spray pump delivers about 50 mcg of mometasone furoate per metered spray and about 120 metered doses per 17-g container.1
Titrate dosage to the lowest possible effective level.1 (See Pediatric Use under Cautions.)

Cautions for Mometasone Furoate
Known hypersensitivity to mometasone furoate or any ingredient in the formulation.1
Withdrawal of Systemic Corticosteroid Therapy
Possible corticosteroid withdrawal symptoms (e.g., joint pain, muscular pain, lassitude, depression), acute adrenal insufficiency, or severe symptomatic exacerbation of asthma or other clinical conditions if prolonged systemic corticosteroid therapy is replaced with topical corticosteroid therapy; careful monitoring recommended.1
Use particular caution in patients with associated asthma or other conditions that may be exacerbated by too rapid a reduction in systemic corticosteroid dosage.1
Excessive intranasal dosages or use in patients who are particularly sensitive to corticosteroid effects due to recent systemic corticosteroid therapy may cause systemic corticosteroid effects (e.g., menstrual irregularities, acneiform lesions, cushingoid features).1 (See Systemic Corticosteroid Effects under Cautions.)
Increased susceptibility to infections in patients who are taking immunosuppressant drugs.1 Certain infections (e.g., varicella [chickenpox], measles) can be serious or even fatal in such patients, particularly in children.1
Exposure to varicella and measles should be avoided in previously unexposed patients.1 If exposure to varicella or measles occurs in susceptible patients, consider administering varicella zoster immune globulin (VZIG) or immune globulin (IG), respectively.1 Consider treatment with an antiviral agent if varicella develops.1
Systemic Corticosteroid Effects
Possible growth suppression in children or adolescents.1 (See Pediatric Use under Cautions.)
Excessive intranasal dosages or use in patients who are particularly sensitive to corticosteroid effects may increase risk of systemic corticosteroid effects (e.g., hypercorticism, adrenal suppression).1
Periodically examine nasal passages for signs of mucosal changes during long-term therapy (several months or longer).1
Use not recommended in patients with recent nasal septal ulcers, nasal surgery, or nasal trauma until healing has occurred.1
Use with caution, if at all, in patients with clinical or asymptomatic Mycobacterium tuberculosis infection of the respiratory tract; untreated fungal, bacterial, or systemic viral infections; or ocular herpes simplex infections.1
No ophthalmologic abnormalities (i.e., elevation in intraocular pressure, cataracts) observed in long-term studies with mometasone furoate.1 Glaucoma, increased intraocular pressure, and cataracts have been reported rarely with other nasal or inhaled corticosteroids.1
Monitor patients who have a change in vision and those with a history of glaucoma or cataracts.1
Use during pregnancy may result in hypoadrenalism in infants; monitor these infants carefully.1
Not known whether mometasone furoate is distributed into milk; caution if used in nursing women.1
Safety and efficacy not established in children <2 years of age.1
Intranasal corticosteroids may reduce growth velocity in pediatric patients.1 Routine monitoring of growth (e.g., via stadiometry) recommended.1 Titrate dosage to the lowest possible effective level.1
Adverse effects profiles similar to those in younger adults.1
Common Adverse Effects
Mometasone Furoate Pharmacokinetics
Not known whether mometasone furoate crosses the placenta or distributes into breast milk.1
Plasma Protein Binding
Excreted as metabolites principally via bile and to a lesser extent in urine.1
25°C (may be exposed to 15–30°C); protect from light.1
Inhibits multiple cell types (e.g., mast cells, macrophages, lymphocytes, monocytes, plasma cells) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) involved in inflammation.2 11 a
Inhibits the expression of inflammatory mediators by cells involved in both the early and late phases of the allergic response,2 including reduced histamine and eosinophil cationic protein levels and reduced eosinophils, neutrophils, and epithelial adhesion proteins.a
Decreases nasal reactivity to allergensd and reduces intraepithelial eosinophilia and infiltration of inflammatory cells (e.g., eosinophils, lymphocytes, monocytes, neutrophils, plasma cells) in nasal mucosa.1 11 a
Advice to Patients
Importance of providing patients a copy of the manufacturer’s patient information.1
Advise patients that containers of mometasone nasal spray should be discarded after 120 actuations.1
Advise that the drug usually will provide symptomatic relief within 2 days, but 1–2 weeks of continuous therapy usually are required for optimum effects.1
Importance of contacting a clinician if symptoms worsen or fail to improve.1
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs.1
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1
Importance of informing patients of other important precautionary information. (See Cautions.)
Excipients in commercially available drug preparations may have clinically important effects in some individuals; consult specific product labeling for details.
