New HFA Reliever Inhalers for Asthma- Things You Should Know

Maxair Autohaler requires 2 priming sprays when used for the first time and if not used for 48 hrs. The procedure for priming is unique and should be further reviewed in detail by reading the package insert (or going to the Maxair link below).

Cleaning this (Maxair) inhaler is also unique in that the metal canister should never removed. A cotton tipped swab is used to clean around the nozzle while holding the inhaler upside down (see package details or the link below).

All the above inhalers are forms of aerosols which should be shaken vigorously before using and require full exhalation (completely empty lungs first) before inhaling. Proventil HFA, Proair HFA, Ventolin HFA and Xopenex HFA have 200 doses per canister.

Maxair Autohaler has 400 doses per canister.

Ventolin HFA is the only reliever inhaler that has a dose counter attached to the mouthpiece.

Remember: The metal canisters in these inhalers should never be submerged in water or allowed to get wet (avoid letting them go through a washer or dryer cycle by being left in your pocket).

The costs of these inhalers vary depending on their own individual wholesale / retail cost and degree of insurance coverage (the latter being most important to the insured patient). No particular brand has any proven superior benefit in asthma treatment over another.

Correct inhalation technique, appropriate use (for relief of asthma symptoms or prevention of exercise induced asthma) and proper care and priming are important for achieving good results.

Also remember that reliever inhalers only help to reduce asthma symptoms but do not control asthma or reduce inflammation. Other types of inhalers (controllers) are available and should be used to manage persistent asthma (higher level of severity than mild asthma). Controller inhalers are used on a regular basis under the doctor's orders.
