Asthma Medications

Your doctor decides what type of medicine to give you based on the type of asthma you have, that is, your asthma classification. The guidelines used most often are listed below.

These are general guidelines. Only your doctor can determine your specific asthma classification and the asthma treatment for you. How much medicine you take and when to take it needs to be clearly written in your Asthma Action Plan.

There are different types of long-term control medicines. They can calm your airways and prevent asthma symptoms. Other names for long-term control medicine are:

Long-term control medicines work to prevent or stop the overreactive immune system response that causes inflammation and tightening in your airways. Long-term control medicine works in your body to help prevent or control everyday symptoms of asthma by:

These medicines are taken every day on a long-term basis. Long-term control medicines work best when a certain level is maintained in your bloodstream. Forgetting to take your long-term control medicine or not taking it the correct way can cause unwanted effects. Make sure to talk with your doctor if you are not sure of when or how to take your long-term control medicine. Your medicine instructions should be written in your Asthma Action Plan.

Quick-relief medicines work rapidly to relieve symptoms during an asthma attack. They can "rescue" you and keep your asthma symptoms from getting worse. They do not affect the underlying inflammation that causes asthma symptoms. No matter how mild or severe your asthma is, your doctor will make sure that you have a quick-relief medicine available. Quick-relief medicine usually comes in a canister and is inhaled. Another name for quick-relief medicine is "rescue medicine."

Quick-relief medicines work rapidly to open airways and increase airflow. They can stop your cough, chest tightness, shortness of breath, and wheezing. Your asthma symptoms should ease within 30 minutes. Your doctor will tell you what to do if your quick-relief medicine does not improve your symptoms. Your doctor may prescribe quick-relief medicine to be used just before exercise to prevent symptoms associated with exercise-induced asthma.

Quick-relief medicine should NOT be used on a regularly scheduled basis. Quick-relief medicines ARE used when you feel your symptoms are getting worse and you are developing an asthma attack. You should feel better when you use quick-relief medicine the right way. Information about how and when to take quick-relief medicine should be written in your Asthma Action Plan, too.
