Serevent is used to prevent asthma attacks. Salmeterol is a bronchodilator. It works by relaxing muscles in the airways to improve breathing. It will not treat an asthma attack that has already begun.
Serevent is also used to treat chronic obstructive pulmonary disease (COPD) including emphysema and chronic bronchitis.
It may also be used for other purposes not listed in this medication guide.
Serevent may increase the risk of asthma-related death. Use only the prescribed dose of Serevent, and do not use it for longer than your doctor recommends. Follow all patient instructions for safe use. Tell your doctor if your symptoms do not improve after 1 week of treatment. Do not use Serevent to treat an asthma attack that has already begun. It will not work fast enough. Use only a fast-acting inhalation medication.
Asthma is often treated with a combination of different drugs. If you use Serevent to treat asthma, you must use it together with another asthma control medication. Use all of your medications as directed by your doctor. Talk with your doctor if your medications do not seem to work as well in treating or preventing attacks. Do not change your doses or medication schedule without advice from your doctor.
If you are using Serevent to prevent exercise-induced asthma, use the medicine 30 minutes before exercising, or as directed by your doctor. Allow at least 12 hours to pass before you use the medicine again.
Serevent Diskus is a powder form of Serevent that comes with a special inhaler device preloaded with blister packs containing measured doses of the medicine. The device opens and loads a blister each time you use the inhaler. This device is not to be used with a spacer.
Use Serevent regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Do not stop using Serevent without first talking to your doctor. Your asthma symptoms may get worse after you stop using the medication. If you also use a steroid medication, do not stop using the steroid suddenly or you may have unpleasant withdrawal symptoms. Talk with your doctor about taking less and less of the steroid before stopping completely. Seek medical attention if you think any of your asthma medications are not working as well as usual. An increased need for medication could be an early sign of a serious asthma attack. If you use a peak flow meter at home, call your doctor if your numbers are lower than normal.
Store Serevent at room temperature away from moisture, heat, and sunlight.
Do not try to clean or take apart the Diskus device. Throw it away 6 weeks after you have taken it out of the foil pouch, or if the dose indicator shows a zero, whichever comes first. Each Serevent Diskus device contains 60 doses.
Use only the prescribed dose of Serevent as directed by your doctor.
Store Serevent at room temperature, between 68 and 77 degrees F (20 and 25 degrees C). Store Serevent away from heat, moisture, and direct sunlight. Throw Serevent away 6 weeks after it is removed from the foil pouch. Keep Serevent out of the reach of children and away from pets.
