How Inhalers Work

Both SABA and SAMA inhalers work very quickly to provide relief during asthma attacks or COPD flare-ups. They come prepared with medicine that is released into the lungs through inhalation. When using a metered dose inhaler (MDI), the patient presses down on the canister to release a precise dose of medicine. Breath-actuated inhalers like the Diskus and Twisthaler only release medicine when the patient breathes in. No matter the delivery system, the medication deposits onto the inner walls of the airways to take effect. SAMAs work within 15-30 minutes by blocking muscarinic receptors, while SABAs typically provide relief within 3-5 minutes by relaxing smooth muscles.

How to Use a Rescue Inhaler Properly

Proper technique is important for inhalers to work effectively and deliver the full dose of medication to the lungs. Here are the basic steps for using a metered dose inhaler:

- Remove the cap and shake the inhaler.
- Tilt head back slightly and breathe out fully.
- Place mouthpiece in mouth between teeth and close lips around it
- Press down firmly on the canister to Rescue Inhaler a puff of medicine as breathing in slowly and deeply.
- Hold breath for 10 seconds before breathing out slowly.
- Rinse mouth after use if possible.

It's best to stand or sit up straight when using any type of inhaler. Taking multiple breaths with each puff may also help more medication reach the lungs. Be sure to review the instructions specific to your inhaler model as well. Correct usage is key for inhalers to work as intended.

When Should Inhalers Be Used?

Inhalers are for quick relief during asthma attacks or COPD exacerbations occurring due to triggers like allergens, cold air, exercise and respiratory infections. Common signs that indicate when to use a inhaler include:

- Shortness of breath
- Chest tightness or pain.
- Coughing.
- Wheezing.
- Trouble speaking in full sentences due to breathing difficulty.

It's a good idea to use your inhaler at the first sign of symptoms or before any activity that may trigger respiratory distress like exercise. Carrying the inhaler at all times is important so it's readily available during flare ups. Patients should call their doctor if inhalers need to be used more than 2 times per week, as this could signal worsening asthma or COPD control requiring treatment plan adjustments.
