Asthma medications can help you with your asthma by reducing airway inflammation and/or relaxing the muscles around your airways to relieve airway narrowing.1 Your doctor will prescribe the medication that suits you best based on your asthma symptoms, personal preference, risk of side effects and other considerations such as cost.2
