DRUG INTERACTIONS: Before using this medication, tell your doctor of all prescription and nonprescription medication you may use, especially: other asthma drugs (e.g., quick-relief inhalers), oral corticosteroids (e.g., dexamethasone, prednisone), beta-blockers (e.g., metoprolol, propranolol), MAO inhibitors (e.g., furazolidone, linezolid, moclobemide, phenelzine, procarbazine, selegiline, isocarboxazid, tranylcypromine), tricyclic antidepressants (e.g., amitriptyline, nortriptyline), "water pills" (diuretics such as furosemide, hydrochlorothiazide), HIV protease inhibitors (e.g., lopinavir, ritonavir), azole antifungals (e.g., itraconazole, ketoconazole), "adrenaline-like" stimulants (e.g., pseudoephedrine, ephedra). Use of this inhaler within 2 weeks after stopping MAO inhibitors or tricyclic antidepressants is not recommended, since these medications may increase the serious side effects of salmeterol. Check the labels on all your medicines (e.g., cough-and-cold products, diet aids) because they may contain ingredients that could increase your heart rate or blood pressure. Ask your pharmacist about the safe use of those products. Do not start or stop any medicine without doctor or pharmacist approval.

OVERDOSE: If overdose is suspected, contact your local poison control center or emergency room immediately. US residents can call the US national poison hotline at 1-800-222-1222. Canadian residents should call their local poison control center directly. Symptoms of overdose may include seizures, chest pain, unusually fast/irregular heartbeat, severe muscle weakness/cramping, or fainting .

NOTES: Do not share this medication with others. Laboratory and/or medical tests (e.g., morning cortisol levels, IOP, children's rate of growth) should be performed to monitor your progress or check for side effects. 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 or red range or increased use of quick-relief inhalers). Try to avoid irritants that may trigger an asthma attack such as smoke, pollen, pet dander, dust, or molds.
