formoterol inhalation powder-oral (cont.)
HOW TO USE: Formoterol is inhaled by mouth using the inhaler device provided, twice daily (in the morning and evening, about every 12 hours); or as directed by your doctor. Be sure to inhale forcefully and deeply through the mouthpiece when using this drug. Remove the inhaler from your mouth before breathing out. Learn the proper use of formoterol, and carefully read the patient instruction sheet that comes with the product. Consult your pharmacist if you have any questions. When formoterol is being used to prevent exercise-induced breathing problems (EIB), it should be used at least 15 minutes before exercising. Do not use additional doses of formoterol for the next 12 hours. If you are already using formoterol twice daily, do not use additional doses for EIB. Make sure that you understand when to use this medication in relation to other asthma medications you may be using. For example, acute asthma attacks should still be treated with short-acting (quick-relief) bronchodilators such as albuterol. Your asthma must be stable (not acutely worsening) before starting treatment with formoterol; consult your doctor. Excessive use of formoterol may result in a decrease in drug effectiveness and an increase in serious side effects. Do not exceed the recommended dosage. Do not stop or decrease the dose of other asthma medications (e.g., inhaled corticosteroids such as beclomethasone) without your doctor's approval. Short-acting bronchodilators you are using on a regular schedule every day (such as every six hours) should be stopped while using this drug. Seek immediate medical attention if your asthma worsens. Signs of worsening asthma include: usual doses of your asthma medications no longer control symptoms; the short-acting (quick-relief) inhaler is less effective; you need to use the short-acting inhaler more often than usual (e.g., use of more than 4 puffs per day or more than 1 inhaler every 8 weeks). Do not increase your dose of formoterol in this situation. When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor immediately if this medication stops working well.
SIDE EFFECTS: Trembling, nervousness, headache, dizziness, dry mouth, nausea, tiredness, or trouble sleeping may occur, but should subside as your body adjusts to this medication. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Tell your doctor immediately if any of these serious side effects occur: fast/pounding/irregular heartbeat. Tell your doctor immediately if any of these unlikely but serious side effects occur: chest pain, fast breathing, muscle weakness or cramping. In the unlikely event that you have an allergic reaction to this drug, seek medical attention immediately. Symptoms of an allergic reaction include: swelling, severe dizziness, rash, itching, trouble breathing. Rarely, formoterol can cause a worsening of breathing problems (e.g. paradoxical bronchospasm) that may be life threatening. If this occurs, immediately seek medical attention. To relieve dry mouth, suck on (sugarless) hard candy or ice chips; chew (sugarless) gum, drink water or use saliva substitute. If you notice other effects not listed above, contact your doctor or pharmacist.
