Asthma medicine helps prevent the symptoms of asthma that inhibit the possibility of doing activities that you want to when you want to do them. Symptoms such as wheezing, shortness of breath, and coughing can be prevented completely or to some degree by using the correct asthma medication. There are generally two types of asthma medicine – controllers and relievers.
Controllers are typically used every day, sometimes twice a day. Controllers prevent asthma symptoms, asthma attacks, and lung damage by relaxing and widening the airways in the body. Some also reduce swelling of the airways. Controllers should not be used to relieve asthma symptoms. Controller medication is most often inhaled and side effects may include fast heartbeat, nervousness, headaches, and hoarseness or coughing.
