Medication does not cure asthma. But it is an important part of managing the condition. Medications for asthma treatment are used to:

• Prevent and control the underlying airway inflammation, to minimize asthma symptoms.
• Decrease the severity, frequency, and duration of asthma attacks.
• Treat the attacks as they occur.

asthma medications are divided into two groups: those for prevention and long-term control of inflammation and those that provide quick relief for asthma attacks. Most people with persistent asthma need to use long-term medications daily. Quick-relief medications are used as needed and provide rapid relief of symptoms during asthma attacks.

Because asthma develops from a complex interaction of genetics, environmental factors, and the reaction of the immune system, different people may use different medications and doses of medications. Special consideration may be necessary if you:

• Are pregnant. If a woman had asthma before becoming pregnant, her symptoms may become better or worse during pregnancy. Pregnant women whose asthma is not well controlled may be at risk for a number of complications.
• Are an older adult. Older adults tend to have worse asthma symptoms and a higher risk of death from asthma than younger people. They may also have one or more other health conditions or take other medications that can make asthma symptoms worse.
• Have exercise-induced asthma. Exercise often causes asthma symptoms. Steps you can take to reduce the risk of this include using medication immediately before you exercise.
• Need surgery. People with moderate to severe asthma are at higher risk than people who do not have asthma of developing problems during and after surgery.

Medication delivery

Most medications for asthma are inhaled. Inhaled medications are used because a specific dose of the medication can be given directly to the bronchial tubes. Different types of delivery systems may be used to do this, and one type may be more suitable for certain people or age groups than another. Delivery systems include metered-dose and dry powder inhalers and nebulizers. A metered-dose inhaler is used most often.

Most health professionals recommend that everyone who uses a metered-dose inhaler (MDI) also use a spacer, which is attached to the MDI. A spacer may deliver the medication to your lungs better than an inhaler alone, and for many people it is easier to use than an MDI alone. Using a spacer with inhaled corticosteroids can help reduce their side effects and result in less use of oral corticosteroids.

It is important to keep track of the inhaler doses and discard the inhaler when you have used the number of doses indicated on the package labeling. This not only prevents you from having an empty inhaler when you need medication, but it also prevents you from inhaling only propellant after the medication has run out. For more information, see:
