  • (200mcg/5mcg)/actuation

Asthma

Indicated for asthma in patients who are not adequately controlled on a long-term asthma-control medication such as an inhaled corticosteroid (ICS) or whose disease warrants initiation of treatment with both an ICS and long-acting beta2-adrenergic agonist (LABA)

Initial: 200 mcg/10 mcg (2 actuations of 100 mcg/5 mcg) inhaled PO q12hr; may increase to higher dose after 2 wk if inadequate response; maximum benefit may not be achieved for 1 week or longer after beginning treatment

Severe asthma (initial) or inadequate response to lower dose (after 2 wk): 400 mcg/10 mcg (2 actuations of 200 mcg/5 mcg) inhaled PO q12hr

Not to exceed more than 2 inhalations twice daily of prescribed strength

Maximum daily dose: 800 mcg/20 mcg daily (ie, 2 actuations of 200 mcg/5 mcg q12hr)If therapy fails to provide adequate control of asthma, re-evaluate therapeutic regimen; consider replacing with higher strength, adding additional inhaled corticosteroid, or initiating oral corticosteroids

If symptoms arise between doses, an inhaled short-acting beta2-agonist should be taken for immediate relief

              Warnings

              Contraindications

              Hypersensitivity

              Primary treatment for acute bronchospasm, status asthmaticus, or exercise-induced bronchospasm

              Cautions

              Risk of LABAs used as monotherapy

              • Use of LABAs as monotherapy (without inhaled corticosteroids) for asthma is associated with an increased risk of asthma-related death
              • Data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patient
              • These findings are considered a class effect of LABA monotherapy
              • When LABA are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone

              Fungal infections

              • Localized infections of the mouth and pharynx with Candida albicans reported; if oropharyngeal candidiasis develops, treat with appropriate local or systemic (i.e., oral) antifungal therapy while remaining on treatment; at times therapy may need to be interrupted
              • To reduce risk of oropharyngeal candidiasis, after dosing, advise patients to rinse their mouth with water and spit out the contents without swallowing

              Do not use to treat acutely deteriorating asthma or acute symptoms; additionally, increased inhaled short-acting beta agonist (SABA) use is marker of deteriorating asthma

              Do not use in combination with additional LABA, because of risk of overdose

              Localized Candida albicans infections develop in mouth and pharynx in some patients; to reduce risk, mouth must be rinsed after inhalation

              Persons who are using drugs that suppress the immune system are more susceptible to infections than healthy individuals; risk of more serious or fatal course of chickenpox or measles exists in susceptible patients (eg, unvaccinated or immunologically unexposed individuals); care must be taken to avoid exposure

              Because of possibility of systemic absorption of inhaled corticosteroids, patients should be observed carefully for any evidence of systemic corticosteroid effects; particular care should be taken in observing patients postoperatively or during periods of stress for evidence of inadequate adrenal response

              Particular care is needed in switching patients from systemic to inhaled corticosteroids; potentially fatal adrenal insufficiency may occur before or afterward; taper withdrawal gradually

              During stress or severe asthma attack, patients who have been withdrawn from systemic corticosteroids should resume PO corticosteroids immediately

              Excessive use may suppress hypothalamic-pituitary-adrenal function; monitor closely, especially postoperatively or during periods of stress

              Risk of paradoxical bronchospasm, which may be life-threatening; discontinue, and treat immediately with inhaled SABA

              Cardiovascular and central nervous system (CNS) effects may occur as consequences of excess beta-adrenergic stimulation; may result in asthma-related death; caution must be exercised in patients with cardiovascular (eg, aneurysm, pheochromocytoma) or convulsive disorders or thyrotoxicosis

              Long-term administration of corticosteroids may decrease in bone mineral density; monitor patients at risk

              May decrease growth velocity in children

              Risk of cataracts, glaucoma, and increased intraocular pressure; consider referral to an ophthalmologist in patients who develop ocular symptoms or use therapy long term

              Risk of systemic eosinophilic conditions, some consistent with Churg-Strauss syndrome

              Risk of transient hypokalemia; supplementation may not be necessary

              Exercise caution when considering coadministration with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, cobicistat-containing products, atazanavir, telithromycin); consider benefit of coadministration versus potential risk of systemic corticosteroid effects, in which case patients should be monitored for systemic corticosteroid side effects

              Prolonged treatment with corticosteroids associated with development of Kaposi sarcoma; consider discontinuing therapy if it occurs

              Psychiatric disturbances reported with corticoid use; therapy may exacerbate preexisting psychiatric conditions

              Potential worsening of existing tuberculosis, fungal, bacterial, viral, or parasitic infection; or ocular herpes simplex infections may occur; more serious or even fatal course of chickenpox or measles can occur in susceptible patients; use with caution in patients with these infections because of potential for worsening of these infections

              Risk of impaired adrenal function when transferring from oral steroids; taper patients slowly from systemic corticosteroids if transferring to inhaler

              Hypercorticism and adrenal suppression; may occur with very high dosages or at regular dosage in susceptible individuals

              Decreases in bone mineral density; monitor patients with major risk factors for decreased bone mineral content

              Pregnancy & Lactation

              Pregnancy: There are no randomized clinical studies in pregnant women; there are clinical considerations with use in pregnant women In women with poorly or moderately controlled asthma, there is increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate; pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control

              Lactation: There are no available data on the presence of mometasone furoate, or formoterol fumarate in human milk; the effects on the breastfed child, or the effects on milk production; The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition

              Pregnancy Categories

              A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

              B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

              C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

              D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

              X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

              NA: Information not available.
