Metered-Dose Inhalers
Metered-dose inhalers use chemical propellants to expel the medication from the inhaler device. To administer the medication, the patient may either use direct inhalation or squeeze the inhaler's canister.
Dry Powder Inhalers
Dry powder inhalers release the medication via rapid inhalation instead of using chemical propellants. The strength of the inhalation required is stronger than that needed to release the medication of a metered-dose inhaler.
Nebulizers - An Inhaler Alternative
Because of the coordination and strength needed to use metered-dose inhalers and dry powder inhalers, some people may choose to use a nebulizer instead. Nebulizers convert medication into a fine mist and deliver the medication through a face mask that covers the mouth and nose.If you are having difficulty using your inhaler, a nebulizer may be a good alternative. Talk to your doctor about the different types of inhalers available. Discuss any difficulties you may be having and find out if a nebulizer may be a better alternative for you.
