Inhaler technique

Common devices include metered dose inhalers, often called puffers, which can often be used with a spacer, and dry powder inhalers. A spacer holds the medicine so you can breathe it in slowly, helping more reach the small airways and less land in your mouth and throat. If your inhaler contains a steroid, rinse your mouth with water or brush your teeth afterwards to help prevent oral thrush.

It is advisable to have your technique checked if medicine comes out of your mouth, your symptoms are not improving, you have a new inhaler, or it has not been checked in the past 12 months. Ask your doctor, pharmacist or nurse to show you. Wash a spacer in warm water with dishwashing detergent and let it air dry without wiping, and check it for cracks. The National Asthma Council Australia advises replacing a spacer after 12 months of use.
