subject: What are the Various Ways to Prevent Asthma? [print this page] Asthma can be prevented as well with prescription medications. Corticosteroids are anti-inflammatory medications that are highly recommended. This medication is generally prescribed as oral inhalers. Over time, the inflammation will be reduced in the airways with this medication. Leukotriene blocker is another preventative medicine that is designed to stop the production of the chemical leukotriene, which is what causes the broncial tubes to swell and excess mucus production. While doctors advise both medications, neither is supposed to provide relief immediately.
