Across FDA labelling, products containing SALMETEROL XINAFOATE are most often described in connection with: serevent diskus, treatment asthma, patients aged, prevention exercise-induced, chronic obstructive, pulmonary disease, important limitation, relief acute. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE SEREVENT DISKUS is a LABA indicated for: • Treatment of asthma in patients aged 4 years and older with an ICS. ( 1.1 ) • Prevention of exercise-induced bronchospasm (EIB) in patients aged 4 years and older. ( 1.2 ) • Maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD). ( 1.3 ) Important limitation of use: Not indicated for relief of acute bronchospasm. ( 1.1 , 1.3 ) 1.1 Treatment of Asthma SEREVENT DISKUS is indicated for the treatment of asthma and in the prevention of bronchospasm only as concomitant therapy with an ICS in patients aged 4 years and older with reversible obstructive airway disease, including patients with symptoms of nocturnal asthma. LABA, such as salmeterol, the active ingredient in SEREVENT DISKUS, as monotherapy (without ICS) increase the risk of asthma-related death [see Warnings and Precautions ( 5.1 )] . Use of SEREVENT DISKUS for the treatment of asthma without concomitant use of an ICS is contraindicated [see Contraindications ( 4 )] . Use SEREVENT DISKUS only as additional therapy for patients with asthma who are currently taking but are inadequately controlled on an ICS. Do not use SEREVENT DISKUS for patients whose asthma is adequately controlled on low- or medium-dose ICS. Pediatric and Adolescent Patients Available data from controlled clinical trials suggest that LABA as monotherapy increase the risk of asthma-related hospitalization in pediatric and adolescent patients. For pediatric and adolescent patients with asthma who require addition of a LABA to an ICS, a fixed-dose combination product containing both an ICS and a LABA should ordinarily be used to ensure adherence with both drugs. In cases where use of a separate ICS and a LABA is clinically indicated, appropriate steps must be taken to ensure adherence with both treatment components. If adherence cannot be assured, a fixed-dose combination product containing both an ICS and a LABA is recommended. Important Limitation of Use SEREVENT DISKUS is NOT indicated for the relief of acute bronchospasm. 1.2 Prevention of Exercise-Induced Bronchospasm SEREVENT DISKUS is also indicated for prevention of exercise-induced bronchospasm (EIB) in patients aged 4 years and older. Use of SEREVENT DISKUS as a single agent for the prevention of EIB may be clinically indicated in patients who do not have persistent asthma. In patients with persistent asthma, use of SEREVENT DISKUS for the prevention of EIB may be clinically indicated, but the treatment of asthma should include an ICS. 1.3 Maintenance Treatment of Chronic Obstructive Pulmonary Disease SEREVENT DISKUS is indicated for the long-term twice-daily administration in the maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD) (including emphysema and chronic bronchitis). Important Limitation of Use SEREVENT DISKUS is NOT indicated for the relief of acute bronchospasm.

2 DOSAGE AND ADMINISTRATION SEREVENT DISKUS should be administered by the orally inhaled route only. More frequent administration or a greater number of inhalations (more than 1 inhalation twice daily) is not recommended as some patients are more likely to experience adverse effects. Patients using SEREVENT DISKUS should not use additional LABA for any reason. [See Warnings and Precautions ( 5.4 , 5.6 ).] • For oral inhalation only. ( 2 ) • Treatment of asthma in patients aged 4 years and older: 1 inhalation twice daily in addition to concomitant treatment with an ICS. ( 2.1 ) • EIB: 1 inhalation at least 30 minutes before exercise. ( 2.2 ) • Maintenance treatment of bronchospasm associated with COPD: 1 inhalation twice daily. ( 2.3 ) 2.1 Asthma LABA, such as salmeterol, the active ingredient in SEREVENT DISKUS, as monotherapy (without ICS) increase the risk of asthma-related death [see Warnings and Precautions ( 5.1 )]. Because of this risk, use of SEREVENT DISKUS for the treatment of asthma without concomitant use of an ICS is contraindicated. Use SEREVENT DISKUS only as additional therapy for patients with asthma who are currently taking but are inadequately controlled on an ICS. Do not use SEREVENT DISKUS for patients whose asthma is adequately controlled on low- or medium-dose ICS. Pediatric and Adolescent Patients Available data from controlled clinical trials suggest that LABA as monotherapy increase the risk of asthma-related hospitalization in pediatric and adolescent patients. For patients with asthma younger than 18 years who require addition of a LABA to an ICS, a fixed-dose combination product containing both an ICS and a LABA should ordinarily be used to ensure adherence with both drugs. In cases where use of a separate ICS and a LABA is clinically indicated, appropriate steps must be taken to ensure adherence with both treatment components. If adherence cannot be assured, a fixed-dose combination product containing both an ICS and a LABA is recommended. For bronchodilatation and prevention of symptoms of asthma, including the symptoms of nocturnal asthma, the usual dosage for adults and children aged 4 years and older is 1 inhalation (50 mcg) twice daily, approximately 12 hours apart. If a previously effective dosage regimen fails to provide the usual response, medical advice should be sought immediately as this is often a sign of destabilization of asthma. Under these circumstances, the therapeutic regimen should be reevaluated. If symptoms arise in the period between doses, an inhaled, short-acting beta 2 -agonist should be taken for immediate relief. 2.2 Exercise-Induced Bronchospasm Use of SEREVENT DISKUS as a single agent for the prevention of EIB may be clinically indicated in patients who do not have persistent asthma. In patients with persistent asthma, use of SEREVENT DISKUS for the prevention of EIB may be clinically indicated, but the treatment of asthma should include an ICS. One inhalation of SEREVENT DISKUS at least 30 minutes before exercise has been shown to protect patients against EIB. When used intermittently as needed for prevention of EIB, this protection may last up to 9 hours in adults and adolescents and up to 12 hours in patients aged 4 to 11 years. Additional doses of SEREVENT should not be used for 12 hours after the administration of this drug. Patients who are receiving SEREVENT DISKUS twice daily should not use additional SEREVENT for prevention of EIB. 2.3 Chronic Obstructive Pulmonary Disease For maintenance treatment of bronchospasm associated with COPD (including chronic bronchitis and emphysema), the dosage for adults is 1 inhalation (50 mcg) twice daily, approximately 12 hours apart.

4 CONTRAINDICATIONS Use of SEREVENT DISKUS for the treatment of asthma without concomitant use of an ICS is contraindicated [see Warnings and Precautions ( 5.1 )] . The use of SEREVENT DISKUS is contraindicated in the following conditions: • Primary treatment of status asthmaticus or other acute episodes of asthma or COPD where intensive measures are required [see Warnings and Precautions ( 5.2 )] • Severe hypersensitivity to milk proteins or demonstrated hypersensitivity to salmeterol or any of the excipients [see Warnings and Precautions ( 5.7 ), Adverse Reactions ( 6.3 ), Description ( 11 )] • Asthma: Without concomitant use of an ICS. ( 4 ) • Primary treatment of status asthmaticus or acute episodes of asthma or COPD requiring intensive measures. ( 4 ) • Severe hypersensitivity to milk proteins or demonstrated hypersensitivity to salmeterol or any of the excipients. ( 4 )

6 ADVERSE REACTIONS LABA, including salmeterol, the active ingredient in SEREVENT DISKUS, as monotherapy (without ICS) increase the risk of asthma-related death. Data from a large 28-week placebo-controlled U.S. trial that compared the safety of salmeterol or placebo added to usual asthma therapy showed an increase in asthma-related deaths in subjects receiving salmeterol. Available data from controlled clinical trials suggest that LABA as monotherapy increase the risk of asthma-related hospitalization in pediatric and adolescent patients [see Warnings and Precautions ( 5.1 ), Clinical Studies ( 14.1 )] . Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Most common adverse reactions (incidence ≥5%) are: • Asthma: Headache, influenza, nasal/sinus congestion, pharyngitis, rhinitis, tracheitis/bronchitis. ( 6.1 ) • COPD: Cough, headache, musculoskeletal pain, throat irritation, viral respiratory infection.

Table 1 reports the incidence of adverse reactions in these 2 trials. Table 1. Adverse Reactions with SEREVENT DISKUS with ≥3% Incidence and More Common than Placebo in Adult and Adolescent Subjects with Asthma a a Table 1 includes all events (whether considered drug-related or nondrug-related by the investigator) that occurred at a rate of ≥3% in the group receiving SEREVENT DISKUS and were more common than in the placebo group. Adverse Event Percent of Subjects SEREVENT DISKUS 50 mcg Twice Daily (n = 149) Albuterol Inhalation Aerosol 180 mcg 4 Times Daily (n = 150) Placebo (n = 152) Ear, nose, and throat Nasal/sinus congestion, pallor 9 8 6 Rhinitis 5 4 4 Neurological Headache 13 12 9 Respiratory Asthma 3 <1 1 Tracheitis/bronchitis 7 3 4 Influenza 5 5 2 Pharyngitis, sinusitis, upper respiratory tract infection, and cough occurred at ≥3% but were more common in the placebo group. However, throat irritation has been described at rates exceeding that of placebo in other controlled clinical trials. Additional Adverse Reactions: Other adverse reactions not previously listed, whether considered drug-related or not by the investigators, that were reported more frequently by subjects with asthma treated with SEREVENT DISKUS compared with subjects treated with placebo include the following: contact dermatitis, eczema, localized aches and pains, nausea, oral mucosal abnormality, pain in joint, paresthesia, pyrexia of unknown origin, sinus headache, and sleep disturbance. Pediatric Subjects Aged 4 to 11 Years Two multicenter, 12-week, controlled trials have evaluated twice-daily doses of SEREVENT DISKUS in subjects aged 4 to 11 years with asthma. Table 2 includes all events (whether considered drug-related or nondrug-related by the investigator) that occurred at a rate of ≥3% in the group receiving SEREVENT DISKUS and were more common than in the placebo group. Table 2. Adverse Reaction Incidence in Two 12-Week Pediatric Clinical Trials in Subjects with Asthma Adverse Event Percent of Subjects SEREVENT DISKUS 50 mcg Twice Daily (n = 211) Albuterol Inhalation Aerosol 200 mcg 4 Times Daily (n = 115) Placebo (n = 215) Ear, nose, and throat Ear signs and symptoms 4 9 3 Pharyngitis 6 3 3 Neurological Headache 17 20 14 Respiratory Asthma 4 <1 2 Skin Skin rashes 4 2 3 Urticaria 3 2 0 The following events were reported at an incidence of >1% in the salmeterol group and with a higher incidence than in the albuterol and placebo groups: gastrointestinal signs and symptoms, lower respiratory signs and symptoms, photodermatitis, and arthralgia and articular rheumatism. In clinical trials evaluating concurrent therapy of salmeterol with ICS, adverse events were consistent with those previously reported for salmeterol, or with events that would be expected with the use of ICS. Laboratory Test Abnormalities Elevation of hepatic enzymes was reported in ≥1% of subjects in clinical trials. The elevations were transient and did not lead to discontinuation from the trials. In addition, there were no clinically relevant changes noted in glucose or potassium. 6.2 Clinical Trials Experience in Chronic Obstructive Pulmonary Disease Two multicenter, 24-week, placebo-controlled U.S. trials evaluated twice-daily doses of SEREVENT DISKUS in subjects with COPD. For presentation ( Table 3 ), the placebo data from a third trial, identical in design, subject entrance criteria, and overall conduct but comparing fluticasone propionate with placebo, were integrated with the placebo data from these 2 trials (total N = 341 for salmeterol and 576 for placebo). Table 3. Adverse Reactions with SEREVENT DISKUS with ≥3% Incidence in U.S. Controlled Clinical Trials in Subjects with Chronic Obstructive Pulmonary Disease a a Table 3 includes all events (whether considered drug-related or nondrug-related by the investigator) that occurred at a rate of ≥3% in the group receiving SEREVENT DISKUS and were more common than in the placebo group. Adverse Event Percent of Subjects SEREVENT DISKUS 50 mcg Twice Daily (n = 341) Placebo (n = 576) Cardiovascular Hypertension 4 2 Ear, nose, and throat Throat irritation 7 6 Nasal congestion/blockage 4 3 Sinusitis 4 2 Ear signs and symptoms 3 1 Gastrointestinal Nausea and vomiting 3 3 Lower respiratory Cough 5 4 Rhinitis 4 2 Viral respiratory infection 5 4 Musculoskeletal Musculoskeletal pain 12 10 Muscle cramps and spasms 3 1 Neurological Headache 14 11 Dizziness 4 2 Average duration of exposure (days) 138.5 128.9 Additional Adverse Reactions Other adverse reactions occurring in the group receiving SEREVENT DISKUS that occurred at a frequency of ≥1% and were more common than in the placebo group were as follows: anxiety; arthralgia and articular rheumatism; bone and skeletal pain; candidiasis mouth/throat; dental discomfort and pain; dyspeptic symptoms; edema and swelling; gastrointestinal infections; hyperglycemia; hyposalivation; keratitis and conjunctivitis; lower respiratory signs and symptoms; migraines; muscle pain; muscle stiffness, tightness, and rigidity; musculoskeletal inflammation; pain; and skin rashes. Adverse reactions to salmeterol are similar in nature to those seen with other selective beta 2 -adrenoceptor agonists, e.g., tachycardia; palpitations; immediate hypersensitivity reactions, including urticaria, angioedema, rash, bronchospasm; headache; tremor; nervousness; and paradoxical bronchospasm. Laboratory Abnormalities There were no clinically relevant changes in these trials. Specifically, no changes in potassium were noted. 6.3 Postmarketing Experience In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during postapproval use of salmeterol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to salmeterol or a combination of these factors. In extensive U.S. and worldwide postmarketing experience with salmeterol, serious exacerbations of asthma, including some that have been fatal, have been reported. In most cases, these have occurred in patients with severe asthma and/or in some patients in whom asthma has been acutely deteriorating [see Warnings and Precautions ( 5.2 )] , but they have also occurred in a few patients with less severe asthma. It was not possible from these reports to determine whether salmeterol contributed to these events. Cardiovascular Arrhythmias (including atrial fibrillation, supraventricular tachycardia, extrasystoles) and anaphylaxis. Non-Site Specific Very rare anaphylactic reaction in patients with severe milk protein allergy. Respiratory Reports of upper airway symptoms of laryngeal spasm, irritation, or swelling such as stridor or choking; oropharyngeal irritation.
