If you're one of the millions of Americans with allergic asthma, treatments can help you live a full and active life.
Rescue Inhalers (Short-Acting Bronchodilators)
They're often called rescue inhalers because they come in a small inhaler that you carry with you and puff when you have symptoms. The effects last 4-6 hours.
You inhale these drugs through a portable device. They work by curbing inflammation in your lungs' airways.
They're called "controller" medications because they help control your asthma over longer periods of time. These medications can help keep your lungs working better after future asthma attacks. You probably won't need your rescue inhaler as much either.
Long-acting bronchodilators are another type of controller medication. They work like rescue inhalers, but the effects last longer, usually about 12 hours. You use them regularly, twice a day.
You should only use them along with inhaled steroids, not ever as the only medication to control your asthma.
These drugs shut down the effects of molecules called leukotrienes, which trigger airway inflammation.
Prednisone is a common steroid used by people whose rescue inhaler doesn't help enough when they have a severe asthma attack. It's usually taken as a pill. It works by lessening the inflammation that causes the serious symptoms.
You should use steroids only when you need them, because they can cause serious side effects if you take high doses for a long time.
Xolair ( omalizumab) is usually a last-resort medication for people with severe asthma that doesn't go away and isn't controlled with other treatments. It prevents cells in your body from starting the inflammation process and makes you less sensitive to your triggers.
It's given as an injection every 2 or 4 weeks at your doctor's office, because you might have a severe allergic reaction to it. It doesn't often cause other side effects, but it is expensive.
