About Observational Studies
This was an observational study. Unlike randomized controlled trials, observational studies such as these do not imply causality, though they can imply association of the treatment to the outcome. Even though outcomes were adjusted for severity using known subject demographics, asthma-related outcomes are influenced by many factors, such as prescriber and clinical factors. These factors were not measured or evaluated in this study.
Important Information about Advair
Advair won't replace fast-acting inhalers for sudden symptoms and should not be taken more than twice a day. Advair contains salmeterol. In patients with asthma, medicines like salmeterol may increase the chance of asthma-related death. So Advair is not for people whose asthma is well controlled on another controller medicine. People should speak to their doctor about the risks and benefits of treating their asthma with Advair. People taking Advair should see their doctor if their asthma does not improve. Thrush in the mouth and throat may occur. People should tell their doctor if they have a heart condition or high blood pressure. Some people may experience increased blood pressure, heart rate, or changes in heart rhythm. Advair Diskus is for patients 4 years and older. For patients 4 to 11 years old, Advair Diskus 100/50 is for those who have asthma symptoms while on an inhaled corticosteroid. Advair HFA is for patients 12 years and older.
