How to Use an Inhaler

At Banner Health, we want you to feel confident managing your asthma so you can focus on the things that matter most. Inhalers are a key part of asthma treatment, but they only work well if used correctly.  

If you're ever unsure whether you're using your inhaler the right way, reach out to your doctor for support or a hands-on review. 

Inhalers come in different types and delivery methods - and each one requires a slightly different technique. You may use one or more inhalers depending on your treatment plan. 

Types of inhalers 

Inhalers can be grouped by either the medication they deliver or how they deliver it into your lungs. 

Medication-based inhalers 

Daily control inhalers (controller or maintenance medications) 

These are taken every day - even when you feel fine - to reduce airway inflammation and prevent symptoms. They help keep asthma under control over time. It may take 2 to 4 weeks before you notice improvement. 

• Used once or twice daily 
• Helps prevent asthma flare-ups 
• Do not stop using unless directed by your doctor 

Rescue inhalers (quick-relief medications) 

These are used as needed when you have sudden asthma symptoms or are about to do something that may trigger symptoms, such as exercise. 

• Works within minutes 
• Effects last 4 to 6 hours 
• Everyone with asthma should carry one 

Delivery-based inhalers 

There are three main types of inhalers based on how the medication is delivered to your lungs. 

How to use a dry powder inhaler (DPI) 

Dry powder inhalers deliver medication in a powdered form. Some are single-use and must be loaded before each dose, while others contain multiple doses. 

Steps: 

1. Remove the cap. Load the dose if required. 
2. Breathe out slowly (not into the mouthpiece). 
3. Place the mouthpiece between your teeth and seal your lips around it. 
4. Inhale deeply through your mouth for 2–3 seconds. 
5. Remove the inhaler and hold your breath as long as possible. 
6. Breathe out slowly. 
7. If your medication contains a steroid, rinse your mouth and gargle with water. Spit it out. 

How to use a metered dose inhaler (MDI) 

Metered dose inhalers spray medication using a pressurized canister. You may use a spacer to make delivery easier. 

Steps: 

1. Prime the inhaler (if new or not used in 2+ weeks): Shake well and spray 4 times away from your face. 
2. Shake the inhaler before use. 
3. Breathe out completely. 
4. Place the mouthpiece between your teeth and seal your lips, or hold it two finger-widths from your mouth. 
5. Press the canister while breathing in slowly for 4–6 seconds. 
6. Hold your breath as long as possible, then exhale. 
7. Wait 15–30 seconds before a second puff. Shake the inhaler again before using. 
8. Recap the mouthpiece. 
9. Rinse your mouth and spit out the water if the medication contains a steroid. 

How to use a soft mist inhaler 

Soft mist inhalers release a slow-moving mist without using pressurized spray. 

Steps: 

1. Prime the inhaler as directed. 
2. Exhale fully. 
3. Place the mouthpiece in your mouth and seal your lips around it. 
4. Begin to inhale slowly while pressing the dose button. 
5. Breathe in fully and hold your breath for 10 seconds. 
6. Exhale slowly. 
7. Recap the inhaler. 

Using an inhaler for exercise-induced asthma 

If your asthma is triggered by physical activity, your rescue inhaler can help prevent symptoms and keep you active. 

• Use your quick-relief inhaler 15 to 30 minutes before exercising. 
• Always carry it with you during activity. 
• Avoid exercising in cold, dry or polluted air if possible. 
• Try less intense activities if high-cardio workouts trigger symptoms. 

Good to know: Regular exercise can actually help improve asthma control by strengthening your lungs and boosting your immune system. Don’t give up—just make adjustments. 

Not sure if you're using your inhaler correctly? 

You’re not alone. Many people need help learning or reviewing proper inhaler technique. If you’re unsure, ask your doctor or asthma specialist to walk through it with you.
