If you have chronic obstructive pulmonary disease (COPD) or asthma, your doctor may prescribe Proventil HFA. This beta-adrenergic receptor agonist medication can prevent exercise-induced bronchospasms and treat and prevent the bronchospasms that can occur with asthma or COPD. A bronchospasm occurs when the airways become constricted. This constriction can cause wheezing, shortness of breath, coughing and chest tightness. The Albuterol Sulfate in Proventil HFA stimulates the beta receptors on the muscles around your airways. This action will relax the muscles, so that your airways open up, making it easier for you to breathe. The drug will also reduce the activity of the mast cells in your lungs. These cells play a part in allergic reactions and inflammation.
Side effects that you may encounter when you use Proventil HFA (Albuterol Sulfate) include a dry throat and mouth, sore throat, runny or stuffy nose, cough, tremors, nervousness, fast heart rate, palpitations, chest pain, hoarseness, headache, dizziness, diarrhea, muscle pain, insomnia, mild nausea and vomiting.
