Inhaled bronchodilators are medication which are inhaled into the lungs. They relax the muscles of the air passages and cause them to open up. This makes it easier to get air in and out of the lungs.
Inhaled bronchodilators provide only temporary relief of symptoms.
They do not treat inflammation, which may be the cause of symptoms in some people. Use your inhaler as prescribed by your physician. It may be prescribed on an as needed basis or on a regular schedule . As a rule, your inhaler should be used no more than two inhalations every four hours, unless prescribed otherwise by your physician. If indicated, your physician may advise you to use your inhaler prior to exercise or activities that cause you to become short of breath.
