What Is a Rescue Inhaler?

A rescue inhaler is a device used to treat a sudden asthma attack. Although rescue inhalers can be used to treat an asthma attack, they do not treat the condition itself, only the symptoms.

  1. How It Works

    • The medication is stored in a canister, usually pressurized, and is released when a button or plunger is depressed. The user's lips are wrapped around a nozzle, and when the button or plunger is depressed, the medication is expelled from the canister to be inhaled by the user.

    The Effect

    • An asthma attack occurs when the muscles around airways become constricted, making breathing difficult. A rescue inhaler's medication will relax these muscles, making it easier for the asthma sufferer to breathe.

    The Medication

    • The medication contained in rescue inhalers will vary; however, some popular types are Albuterol, Metaproternol and Pributerol. Although the exact chemical composition will vary, the chemicals contained in these inhalers will produce the desired effects.

    Side Effects

    • The use of rescue inhalers can produce side effects. Common side effects include nausea, lightheadedness and a slight increase in heart rate.

    Should I Get a Rescue Inhaler?

    • The first step when considering this question is to consult with your doctor to be sure that you have asthma. If this is the case, your doctor may prescribe a rescue inhaler or asthma controller medication.
