Quick-relief medicines for chronic obstructive pulmonary disease (COPD) work quickly to help you breathe better. You take them when you are coughing, wheezing, or having trouble breathing, such as during a flare-up. For this reason, they are also called rescue drugs.
The medical name of these drugs is bronchodilators, meaning medicines that open the airways (bronchi). They relax the muscles of your airways and open them up for easier breathing. You and your doctor can make a plan for the quick-relief drugs that work for you. This plan will include when you should take your medicine and how much you should take.
Follow instructions on how to use your medicines the right way.
Make sure you get your medicine refilled before you run out.
Quick-relief Beta-agonist Inhalers
Quick-relief beta-agonists help you breathe better by relaxing the muscles of your airways. They are short-acting, which means they stay in your system only for a short time.
Some people take them just before exercising. Ask your doctor if you should do this.
If you need to use these drugs more than 3 times a week, or if you use more than one canister a month, your COPD probably is not under control. You should call your doctor.
