Bronchodilators are able to relieve the symptoms of asthma by relaxing the muscles around the airways that can tighten, which allows the airways to open up. Short-acting bronchodilators are also known as rescue inhalers, and can be used to quickly relieve the symptoms. These short-acting bronchodilators should not be used more than twice a week. If they are, a consultation with your physician is essential to get your asthma under control. People with exercise- induced asthma will use the short-acting bronchodilators before exercising.
There are three types of bronchodilators including: beta-agonists, anticholinergics, and theophylline. They are also classified into short-acting and long-acting. Short-acting are also known as rescue-inhalers. These are available in tablets, injections, liquid, or inhaled. The preferred method is through inhalation. Bronchodilators are available by prescription only.
The side effects from bronchodilators depend on the type that you use. Side effects include: headache, nausea, bronchitis, ear infection, etc. Many other medications may also interact with the bronchodilator. Speak with your physician about what medications you are currently on. In very rare cases are side effects life-threatening. If your side effects are life-threatening, then end use and see your physician immediately.
