            Warnings

            Black Box Warnings

            Long-acting beta2-adrenergic agonists (LABA), as monotherapy (without inhaled corticosteroids [ICS]) increase risk of asthma-related death; data from a large placebo-controlled U.S. trial showed an increase in asthma-related deaths in subjects receiving salmeterol alone; use of background ICS was not required in this study; when LABA are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone

            Use of drug for the treatment of asthma as monotherapy without a concomitant ICS is contraindicated; use only as additional therapy for patients with asthma who are currently taking but are inadequately controlled on an ICS; do not use drug 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 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 an 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 recommended

            Contraindications

            Severe hypersensitivity to milk proteins or demonstrated hypersensitivity to drug or excipients

            Primary treatment of status asthmaticus or other acute episodes of asthma or COPD where intensive measures are required

            Treatment of asthma without a concomitant long-term asthma control medication, such as an inhaled corticosteroid

            Cautions

            Use with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension; therapy can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms; although such effects are uncommon after administration of salmeterol at recommended doses, if they occur, the drug may need to be discontinued

            Drug should not be used more often than recommended, at higher doses than recommended, or in conjunction with other medicines containing LABA, as an overdose may result; clinically significant cardiovascular effects and fatalities reported in association with excessive use of inhaled sympathomimetic drugs; patients should not use another medicine containing a LABA (e.g., formoterol fumarate, arformoterol tartrate, indacaterol) for any reason

            Use caution in diabetes mellitus and ketoacidosis; clinically significant and dose-related changes in blood glucose and/or serum potassium seen infrequently during clinical trials at recommended doses

            Not for acute asthma; for acute asthma exacerbations, use short-acting beta-agonists (eg, albuterol)

            Not for acute episodes of COPD

            May increase risk of severe, potentially fatal asthma attacks; small but significant increase in asthma-related deaths for patients using salmeterol vs placebo, with greater risk in African-Americans

            Therapy may produce significant hypokalemia in some patients, possibly through intracellular shunting, which has potential to produce adverse cardiovascular effects; decrease in serum potassium is usually transient, not requiring supplementation

            Use caution in patients with hypokalemia, hepatic impairment, seizure disorders, and hyperthyroidism

            Paradoxical bronchospasm may occur with therapy; if it occurs it should be treated immediately with an inhaled, short-acting bronchodilator; treatment should be discontinued immediately and alternative therapy instituted; upper airway symptoms of laryngeal spasm, irritation, or swelling, such as stridor and choking, have been reported in patients receiving therapy

            When initiating and throughout treatment in patients receiving oral or ICS for treatment of asthma, patients must continue taking a suitable dosage of corticosteroids to maintain clinical stability even if they feel better as a result of initiating salmeterol; any change in corticosteroid dosage should be made only after clinical evaluation

            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

            Immediate hypersensitivity reactions (eg, urticaria, angioedema, rash, bronchospasm, hypotension), including anaphylaxis, may occur with therapy; anaphylactic reactions in patients with severe milk protein allergy after inhalation of powder products containing lactose reported

            Use only for shortest duration of time

            Deterioration of disease

            • Not for use in patients during rapidly deteriorating or potentially life-threatening episodes of asthma or COPD, including patients with significantly increased symptoms
            • Worsening or acutely deteriorating asthma is associated with increase in need for inhaled, short-acting pulmonary#beta2-agonists; decreasing response to usual medications; increasing need for systemic corticosteroids; recent emergency room visits; deteriorating lung function
            • Increasing use of inhaled, short-acting pulmonary#beta2-agonists is a marker of deteriorating asthma; in this situation, the patient requires immediate reevaluation with reassessment of treatment regimen, giving special consideration to possible need for adding additional ICS or initiating systemic corticosteroids; patients should not use drug more than 1 inhalation twice daily

            Drug interaction overview

            • Use of strong cytochrome P450 3A4 (CYP3A4) inhibitors (eg, ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) not recommended because increased cardiovascular adverse effects may occur

            Pregnancy & Lactation

            Pregnancy

            Available data from published epidemiological studies and case reports in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes

            Beta-agonists may interfere with uterine contractility

            There are clinical considerations in pregnant women with asthma

            In women with poorly or moderately controlled asthma, there is increased risk of pre-eclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate

            Severe asthma during pregnancy has been associated with maternal mortality, fetal mortality, or both

            Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control

            Animal data

            • Oral administration of salmeterol to pregnant rabbits caused teratogenicity characteristic of beta-adrenoceptor stimulation at maternal doses approximately 50 times maximum recommended human daily inhaled dose (MRHDID) on an AUC basis

            Labor and delivery

            • There are no adequate and well-controlled human studies that have evaluated effects of therapy during labor and delivery; because of potential for beta-agonist interference with uterine contractility, use during labor should be restricted to those patients in whom the benefits clearly outweigh the risks

            Lactation

            There is no information regarding presence of salmeterol in human milk, effects on breastfed child, or on milk production

            Drug is detected in rat milk; drug concentrations in human plasma after inhaled therapeutic doses are low and therefore concentrations in human breast milk are likely to be low

            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 child from treatment or from 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.

            SALMETEROL DISK INHALER - ORAL INHALATION

            (sal-MET-er-all)

            COMMON BRAND NAME(S): Serevent Diskus

            WARNING: Rarely, when treating asthma, serious (sometimes fatal) asthma-related breathing problems have occurred with the use of long-acting inhaled beta agonists (such as salmeterol). In patients with asthma, this drug should only be prescribed when one long-term medication (such as inhaled corticosteroids) does not control breathing problems or when more than one long-term medication is clearly needed to control breathing problems. Salmeterol must not be used alone to treat asthma. Before using this medication, it is important to learn how to use it properly. Discuss the risks and benefits of treatment with this medication with your doctor.Once asthma symptoms are controlled, if possible, your doctor may stop treatment with salmeterol and continue only your other asthma medications (such as inhaled corticosteroids). Follow your doctor's directions carefully.

            USES: Salmeterol is used as a long-term (maintenance) treatment to prevent or decrease wheezing and trouble breathing caused by asthma or ongoing lung disease (chronic obstructive pulmonary disease-COPD, which includes chronic bronchitis and emphysema). It should only be used long-term if your asthma symptoms are not controlled by your other asthma medications (such as inhaled corticosteroids). Salmeterol must not be used alone to treat asthma. (See also Warning section.) It is also used to prevent asthma brought on by exercise (bronchospasm). Salmeterol works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school.This medication does not work right away and should not be used for sudden attacks of breathing trouble. Your doctor must prescribe a quick-relief medicine/inhaler (such as albuterol) for sudden shortness of breath/asthma attacks while you are on this medication. You should always have a quick-relief inhaler with you. Consult your doctor or pharmacist for more details.This medication should be used in combination with other medications such as long-acting inhaled corticosteroids. However, it should not be used with other long-acting inhaled beta agonists (such as formoterol, combination salmeterol/fluticasone) since this may increase your risk for side effects.It is recommended that children and teenagers, who need to use salmeterol to treat their asthma, should use a combination salmeterol/fluticasone product. Check with your child's doctor to see if this product is the right product for your child.In patients with asthma, this medication should not be used when breathing problems can be controlled with inhaled corticosteroids (such as flunisolide, fluticasone) and occasional use of quick-relief inhalers. (See also Warning section.)If you are regularly taking corticosteroids by mouth (such as prednisone), you should not stop using them or use this inhaled medication instead. Continue to follow your doctor's instructions for taking the corticosteroids by mouth.

            HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using salmeterol and each time you get a refill. Follow the illustrated directions for the proper use of this medication. If you have any questions, ask your doctor or pharmacist.Always activate and use this device in a level, horizontal position.Inhale this medication by mouth as directed by your doctor, usually twice daily (in the morning and evening, 12 hours apart). You may or may not taste/feel the drug when you inhale. Either is normal. Never exhale into the device. Do not use with a spacer. Never wash the mouthpiece or any part of the device.If you are using other inhalers at the same time, wait at least 1 minute between the use of each medication.The dosage is based on your medical condition and response to therapy. Use this medication regularly to receive the most benefit from it. To help you remember, use it at the same times each day. Do not use it more often than prescribed or use more than 1 inhalation twice daily since this may increase the risk of side effects.Do not stop taking this medication or change your dose without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.If you have been using a quick-relief inhaler on a regular daily schedule (such as 4 times daily), you must stop this schedule and only use it as needed for sudden shortness of breath/asthma attacks. Consult your doctor for details.If you are only using this medication occasionally to prevent asthma brought on by exercise (bronchospasm), use it at least 30 minutes before exercise, and do not use another dose for at least 12 hours. If you have sudden asthma/shortness of breath, use a quick-relief inhaler (such as albuterol). Consult your doctor for details.Learn which of your inhalers you should use every day (controller drugs) and which you should use if your breathing suddenly worsens (quick-relief drugs). Ask your doctor ahead of time what you should do if you have new or worsening cough or shortness of breath, wheezing, increased sputum, worsening peak flow meter readings, waking up at night with trouble breathing, if you use your quick-relief inhaler more often (more than 2 days a week), or if your quick-relief inhaler does not seem to be working well. Learn when you can treat sudden breathing problems by yourself and when you must get medical help right away.Tell your doctor if your symptoms do not improve or if they worsen.

            SIDE EFFECTS: Hoarseness, throat irritation, headache, rapid heartbeat, nervousness, cough, dry mouth/throat, or upset stomach may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.Rarely, this medication may cause sudden breathing problems/asthma right after you use it. If this occurs, use your quick-relief inhaler and get medical help right away.Get medical help right away if you have any very serious side effects, including: chest pain, fast/slow/irregular heartbeat, severe dizziness, fainting, seizures.A very serious allergic reaction to this product is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

            PRECAUTIONS: Before using this medication, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this drug, tell your doctor or pharmacist your medical history, especially of: heart problems (such as angina, irregular heartbeat), high blood pressure, diabetes, liver problems, seizures, thyroid problems (such as overactive thyroid).Salmeterol may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using salmeterol, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using salmeterol safely.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this medication passes into breast milk. Consult your doctor before breast-feeding.

            DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Many drugs besides salmeterol may affect the heart rhythm (QT prolongation), including amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others. Before using salmeterol, report all medications you are currently using to your doctor or pharmacist.Other medications can affect the removal of salmeterol from your body, which may affect how salmeterol works. Examples include cobicistat, nefazodone, ritonavir, telithromycin, azole antifungals (such as ketoconazole, itraconazole), macrolide antibiotics (such as clarithromycin), HIV protease inhibitors (such as saquinavir), among others.

            OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include chest pain, fast/irregular heartbeat, headache, fainting.

            NOTES: Do not share this medication with others.Lab and/or medical tests (such as lung function) may be done while you are using this medication. Keep all medical and lab appointments. Consult your doctor for more details.Learn to use a peak flow meter, use it daily, and promptly report worsening asthma (such as readings in the yellow/red range, or increased use of quick-relief inhalers).Avoid allergens/irritants such as smoke, pollen, pet dander, dust, or molds that may worsen asthma and other breathing problems. Ask your doctor or pharmacist if you should have an annual flu shot.

            MISSED DOSE: If you are on a prescribed schedule and miss a dose, skip the missed dose. Use your next dose at the regular time. Do not double the dose to catch up.

            STORAGE: Store at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets.Do not flush medications down the toilet or pour them into a drain unless instructed to do so.
