Serevent Inhaler Overview
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. () 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. Serevent Inhaler 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 Serevent Inhaler. You should always have a quick-relief inhaler with you. Consult your doctor or pharmacist for more details. Serevent Inhaler 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 Serevent Inhaler is the right product for your child. In patients with asthma, Serevent Inhaler should not be used when breathing problems can be controlled with inhaled corticosteroids (such as flunisolide, fluticasone) and occasional use of quick-relief inhalers. () 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.
Serevent Inhaler Warnings
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, Serevent Inhaler 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 Serevent Inhaler, it is important to learn how to use it properly. Discuss the risks and benefits of treatment with Serevent Inhaler 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.

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 Serevent Inhaler 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. If Serevent Inhaler stops working well, or you need to use your quick-relief inhaler more often than usual (4 or more puffs daily or use of more than 1 inhaler every 8 weeks), seek immediate medical attention. It may be a sign of worsening asthma, which is a serious condition. 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.
