In a large clinical study, more patients with asthma who used salmeterol experienced severe episodes of asthma that had to be treated in a hospital or caused death than patients with asthma who did not use salmeterol. If you have asthma, use of salmeterol may increase the chance that you will experience serious or fatal asthma problems.
Your doctor will only prescribe salmeterol if your asthma is so severe that two medications are needed to control it. You should never use salmeterol alone; you must always use it along with another asthma controller medication. Children and teenagers who need to be treated with salmeterol will probably be treated with a product that combines salmeterol and another medication in a single inhaler to make it easier for them to use both medications as prescribed.
Because of the risks of using salmeterol, you should only use salmeterol as long as it is needed to bring your asthma symptoms under control. Once your asthma is controlled, your doctor will probably tell you to stop using salmeterol but continue using the other asthma medication.
Do not use salmeterol if you have asthma that is quickly getting worse. Tell your doctor if you have had many severe asthma attacks or if you have ever been hospitalized because of asthma symptoms. If you have any of the following signs of worsening asthma, call your doctor immediately:
- your short-acting inhaler (inhaled medication such as albuterol [Proventil, Ventolin] that is used to treat sudden attacks of asthma symptoms) does not work as well as it did in the past
- you need to use more puffs than usual of your short-acting inhaler or use it more often
- you need to use four or more puffs per day of your short-acting inhaler for two or more days in a row
- you use more than one canister (200 inhalations) of your short-acting inhaler during an 8-week period
- your peak-flow meter (home device used to test breathing) results show your breathing problems are worsening
- you need to go to the emergency room for asthma treatment.
- your symptoms do not improve after you use salmeterol regularly for one week or your symptoms get worse at any time during your treatment
Talk to your doctor about the risks of using this medication.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with salmeterol and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Why is this medication prescribed?
Salmeterol is used to treat wheezing, shortness of breath, coughing, and chest tightness caused by asthma and chronic obstructive pulmonary disease (COPD; a group of lung diseases that includes chronic bronchitis and emphysema). It also is used to prevent bronchospasm (breathing difficulties) during exercise. Salmeterol is in a class of medications called long-acting beta agonists (LABAs). It works by relaxing and opening air passages in the lungs, making it easier to breathe.
How should this medicine be used?
Salmeterol comes as a dry powder to inhale by mouth using a specially designed inhaler. When salmeterol is used to treat asthma or COPD, it is usually used twice a day, in the morning and evening, about 12 hours apart. Use salmeterol at around the same times every day. When salmeterol is used to prevent breathing difficulties during exercise, it is usually used at least 30 minutes before exercise, but not more often than once every 12 hours. If you are using salmeterol twice a day on a regular basis, do not use another dose before exercising. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use salmeterol exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Talk to your doctor about how you should take your other oral or inhaled medications for asthma during your treatment with salmeterol. If you were taking a corticosteroid (a type of medication used to prevent airway swelling in patients with asthma), you doctor will probably tell you to continue taking it just as you did before you began using salmeterol. If you were using a short acting beta agonist inhaler such as albuterol (Proventil, Ventolin) on a regular basis, your doctor will probably tell you to stop using it regularly, but to continue to use it to treat sudden attacks of asthma symptoms. Follow these directions carefully. Do not change the way you use any of your medications without talking to your doctor.
Do not use salmeterol during an attack of asthma or COPD. Your doctor will prescribe a short-acting inhaler to use during attacks.
Salmeterol controls the symptoms of asthma and other lung diseases but does not cure these conditions. Do not stop using salmeterol without talking to your doctor. If you suddenly stop using salmeterol, your symptoms may worsen.
Before you use the salmeterol inhaler the first time, ask your doctor, pharmacist, or respiratory therapist to show you how to use it. Practice using the inhaler while he or she watches.
To use the inhaler, follow these steps:
- If you will be using a new inhaler for the first time, remove it from the box and the foil wrapper. Fill in the blanks on the inhaler label with the date that you opened the pouch and the date 6 weeks later when you must replace the inhaler.
- Hold the inhaler in one hand, and put the thumb of your other hand on the thumbgrip. Push your thumb away from you as far as it will go until the mouthpiece appears and snaps into position.
- Hold the inhaler in a level, horizontal position with the mouthpiece toward you. Slide the lever away from you as far as it will go until it clicks.
- Every time the lever is pushed back, a dose is ready to inhale. You will see the number in the dose counter go down. Do not waste doses by closing or tilting the inhaler, playing with the lever, or advancing the lever more than once.
- Hold the inhaler level and away from your mouth, and breathe out as far as you comfortably can.
- Keep the inhaler in a level, flat position. Put the mouthpiece to your lips. Breathe in quickly and deeply though the inhaler, not through your nose.
- Remove the inhaler from your mouth, and hold your breath for 10 seconds or as long as you comfortably can. Breathe out slowly.
- You will probably taste or feel the salmeterol powder released by the inhaler. Even if you do not, do not inhale another dose. If you are not sure you are getting your dose of salmeterol, call your doctor or pharmacist.
- Put your thumb on the thumbgrip and slide it back toward you as far as it will go. The device will click shut.
Never exhale into the inhaler, take the inhaler apart, or wash the mouthpiece or any part of the inhaler. Keep the inhaler dry. Do not use the inhaler with a spacer.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away the inhaler 6 weeks after you remove it from the foil overwrap or after every blister has been used (when the dose indicator reads 0), whichever comes first. Talk to your pharmacist about the proper disposal of your medication.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
