Important Info on Serevent

Serevent Effects

Several studies have looked at the effects of Serevent on asthma and chronic obstructive pulmonary disease (COPD).
In clinical studies, Serevent was shown to improve breathing and to decrease the need for rescue inhalers. The medication also decreased the chance of waking up at night due to asthma. In other studies, when Serevent was given to people who were also taking steroid asthma medications, it further improved asthma symptoms. When taken 30 minutes before exercise, it was shown to help prevent exercise-induced asthma attacks.
In studies of Serevent for the treatment of chronic obstructive pulmonary disease, it was given to people with chronic bronchitis (with or without emphysema). People taking the drug showed improved lung function, compared to those not taking it.

When and How to Take It

Following are some general considerations for when and how to take Serevent:
  • The medication is inhaled into the lungs, usually twice daily, with about 12 hours between doses.
  • In the past, Serevent came as a typical inhaler. However, it now comes as Serevent Diskus®, which contains dry powder.
  • The Serevent Diskus is used differently from older inhalers. It contains small foil pockets that are filled with the powder. These pockets are punctured (by sliding the lever until it clicks), and the powder is inhaled using your own breath.
  • Be sure to keep the Serevent Diskus horizontal while using it; otherwise, the powder can spill out. Never exhale into the inhaler, as this will also disrupt the powder.
  • Some people may not taste or feel the fine powder, even if they could taste the medication with the old inhaler. Most of the taste is due to propellants, which are not used in the new Serevent Diskus.
  • It is important that you learn exactly how to use your inhaler. Make sure your healthcare provider shows you the steps needed to use it.
  • Serevent should be taken at the same time each day to maintain an even level in your blood.
  • For the medication to work properly, it must be taken as prescribed. Serevent will not work if you stop taking it.
