Concerns related to adverse effects:
• Adrenal suppression: May cause hypercortisolism or suppression of hypothalamic-pituitary-adrenal (HPA) axis, particularly in younger children or in patients receiving high doses for prolonged periods. HPA axis suppression may lead to adrenal crisis. Withdrawal and discontinuation of a corticosteroid should be done slowly and carefully. Particular care is required when patients are transferred from systemic corticosteroids to inhaled products due to possible adrenal insufficiency or withdrawal from steroids, including an increase in allergic symptoms. Patients receiving >20 mg per day of prednisone (or equivalent) may be most susceptible. 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. Do not use this product to transfer patients from oral corticosteroid therapy.
• Asthma-related deaths: The use of long-acting beta-2 agonists (LABAs) as monotherapy is associated with an increased risk of asthma-related deaths. In a large, randomized, placebo-controlled US trial, salmeterol was associated with an increase in asthma-related deaths (SMART 2006); risk is considered a class effect of LABA monotherapy. Additional data from other clinical trials suggest LABA monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients. However, data from large randomized, double-blind, active-controlled trials do not show a significant increase in the risk of serious asthma-related events (including hospitalizations, intubations, and death) in adult, adolescent, and pediatric (aged 4 to 11 years) patients when fixed-dose LABAs are used with inhaled corticosteroids combined in a single inhaler compared with inhaled corticosteroid monotherapy. In addition, patients receiving fluticasone/salmeterol had fewer severe asthma exacerbations compared with patients receiving fluticasone alone (Peters 2016; Stempel 2016a; Stempel 2016b). Current guidelines recommend the use of an inhaled corticosteroid before adding a LABA (GINA 2015; NIH/NHLBI 2007). Assess patients at regular intervals once asthma control is maintained on combination therapy to determine if step-down therapy is appropriate (without loss of asthma control), and the patient can be maintained on an inhaled corticosteroid only. LABAs are not appropriate in patients whose asthma is adequately controlled on low- or medium-dose inhaled corticosteroids.
• Bone density: Long-term use of inhaled corticosteroids have been associated with decreases in bone mineral density. Use with caution in patients with major risk factors for decreased bone mineral count such as prolonged immobilization, family history of osteoporosis, postmenopausal status, tobacco use, advanced age, poor nutrition, or chronic use of drugs that can reduce bone mass (eg, anticonvulsants or oral corticosteroids); high doses and/or long-term use of inhaled corticosteroids have been associated with decreases in bone mineral density.
• Bronchospasm: Rarely, paradoxical bronchospasm may occur with use of inhaled bronchodilating agents; this should be distinguished from inadequate response.
• Hypersensitivity reactions: Immediate hypersensitivity reactions (urticaria, angioedema, rash, bronchospasm) have been reported.
• Immunosuppression: Prolonged use of corticosteroids may increase the incidence of secondary infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to vaccines. Avoid use if possible in patients with ocular herpes; active or quiescent tuberculosis infections of the respiratory tract; or untreated viral, fungal, or bacterial or parasitic systemic infections. Exposure to chickenpox or measles should be avoided; if the patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin or pooled intravenous immunoglobulin may be indicated; if chickenpox develops, treatment with antiviral agents may be considered. If exposure to measles, prophylaxis with pooled intramuscular immunoglobulin may be indicated.
• Lower respiratory infections: Pneumonia and other lower respiratory tract infections have been reported in patients with COPD following the use of inhaled corticosteroids; monitor COPD patients closely since pneumonia symptoms may overlap symptoms of exacerbations.
• Oral candidiasis: Local oropharyngeal Candida infections have been reported; if this occurs, treat appropriately while either continuing or interrupting (if necessary) budesonide/formoterol therapy.
• Serious effects/fatalities: Do not exceed recommended dose; serious adverse events, including fatalities, have been associated with excessive use of inhaled sympathomimetics.
• Vasculitis: Rare cases of vasculitis (eosinophilic granulomatosis with polyangiitis [formerly known as Churg-Strauss]) or other systemic eosinophilic conditions can occur; often associated with decrease and/or withdrawal of oral corticosteroid therapy following initiation of inhaled corticosteroid.
• Asthma: Appropriate use: Do not use for acute bronchospasm. Short-acting beta-2 agonist (eg, albuterol) should be used for acute symptoms and symptoms occurring between treatments. Do not initiate in patients with significantly worsening or acutely deteriorating asthma.
• Cardiovascular disease: Use with caution in patients with cardiovascular disease (arrhythmia, coronary insufficiency, or hypertension); beta agonists may cause elevation in blood pressure, heart rate and result in CNS stimulation/excitation. Beta-2 agonists may also increase risk of arrhythmias and ECG changes, such as flattening of the T-wave, prolongation of the QTc interval, and ST segment depression. Use with caution following acute MI; corticosteroids have been associated with myocardial rupture.
• COPD: Appropriate use: Do not use for acute episodes of COPD. Do not initiate in patients with significantly worsening or acutely deteriorating COPD. Data are not available to determine if LABA use increases the risk of death in patients with COPD.
• Diabetes: Use with caution in patients with diabetes mellitus; beta-2 agonists may increase serum glucose and aggravate preexisting diabetes mellitus and ketoacidosis.
• Hepatic impairment: Use with caution in patients with hepatic impairment; may lead to accumulation of budesonide and formoterol; monitor closely.
• Hypokalemia: Use with caution in patients with hypokalemia; beta-2 agonists may decrease serum potassium (transient).
• Ocular disease: Use with caution in patients with cataracts and/or glaucoma; increased intraocular pressure, open-angle glaucoma, and cataracts have occurred with prolonged use of inhaled corticosteroids. Consider routine eye exams in chronic users.
• Seizure disorders: Use with caution in patients with seizure disorders; beta agonists may result in CNS stimulation/excitation.
• Thyroid disease: Changes in thyroid status may necessitate dosage adjustments; metabolic clearance of corticosteroids increases in hyperthyroid patients and decreases in hypothyroidism.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult Drug Interactions for more detailed information.
• Pediatric: LABAs may increase the risk of asthma-related hospitalization in pediatric and adolescent patients. Orally inhaled corticosteroids may cause a reduction in growth velocity in pediatric patients (~1 centimeter per year [range 0.3 to 1.8 cm per year] and related to dose and duration of exposure). To minimize the systemic effects of orally inhaled corticosteroids, each patient should be titrated to the lowest effective dose. Growth should be routinely monitored in pediatric patients.
• Discontinuation of systemic corticosteroids: Withdraw systemic corticosteroid therapy with gradual tapering of dose; consider reducing the daily prednisone dose by 2.5 mg on a weekly basis beginning after at least 1 week of inhalation therapy. Monitor lung function, beta agonist use, asthma symptoms, and for signs and symptoms of adrenal insufficiency (fatigue, lassitude, weakness, nausea and vomiting, hypotension) during withdrawal.
FEV1, peak flow meter and/or other pulmonary function tests; monitor growth in pediatric patients, symptom relief, monitor for increased use if short-acting beta2-adrenergic agonists (may be a sign of asthma or COPD deterioration); HPA axis suppression; bone mineral density; blood pressure, heart rate; CNS stimulation; serum glucose, serum potassium
Adverse events were observed in animal reproduction studies using this combination. Refer to individual agents.
• 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 pharyngitis, throat pain, back pain, common cold symptoms, abdominal pain, or rhinitis. Have patient report immediately to prescriber signs of infection, signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of low potassium (muscle pain or weakness, muscle cramps, or an abnormal heartbeat), signs of adrenal gland problems (severe nausea, vomiting, severe dizziness, passing out, muscle weakness, severe fatigue, mood changes, lack of appetite, or weight loss), angina, tachycardia, anxiety, mouth irritation, mouth sores, bone pain, dizziness, passing out, seizures, severe headache, tremors, severe nausea, vomiting, severe loss of strength and energy, insomnia, burning or numbness feeling, flu-like signs, sinusitis, vision changes, eye pain, severe eye irritation, thrush, or signs of a severe pulmonary disorder (lung or breathing problems like difficulty breathing, shortness of breath, or a cough that is new or worse) (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.
