How to Use A Dry-Powder Inhaler

What is a dry-powder inhaler?
A dry-powder inhaler is a handheld device that delivers a dose of medicine as a powder when you inhale. You breathe the medicine deep into your lungs to open your airways.
How do I use a dry-powder inhaler?
Some dry-powder inhalers require you to put the medicine inside the inhaler. Others come with the medicine already inside.
- Follow the instructions to put together your inhaler, and get it ready to use. Open the inhaler mouthpiece, or remove the cap.
- Check to make sure there are no foreign objects in the mouthpiece.
- Breathe out fully, away from the inhaler. Never exhale into your inhaler.
- Hold the inhaler as directed. Do not cover the vents. Place the mouthpiece between your lips tightly to create a seal.
- Breathe in strongly for as long as you can to make the medicine come out.
- Hold your breath for about 10 seconds. Breathe out slowly, away from the inhaler.
- Make sure the counter has counted a dose, if your inhaler has a counter. If your inhaler uses capsules, check the capsule to make sure it is empty.
- Repeat if more puffs are needed.
- Rinse your mouth with water after you use your inhaler, as directed by your healthcare provider. Do not swallow the rinse water.
How do I care for my dry-powder inhaler?
Close the mouthpiece or replace the cap after each use. Store the inhaler in a cool, dry place. Clean the mouthpiece at least once a week with a dry cloth, as directed. Do not use water to clean your dry-powder inhaler.
Call your local emergency number (911 in the US), or have someone call if:
- You feel the muscles around your airway tighten.
- You are so short of breath you cannot talk.
- You have chest pain.
When should I seek immediate care?
- Your lips or nails turn blue or gray.
- The skin between your ribs or around your neck pulls in with every breath.
- You feel short of breath, even after you use your inhaler.
- You cough up blood.
When should I call my doctor?
- Your inhaler does not work properly.
- You cannot inhale strongly enough to make the medicine come out of the inhaler.
- Your medicine is not controlling your symptoms.
- The medicine irritates your mouth or throat, or it causes you to sound hoarse or lose your voice.
- It feels like most of the medicine lands in your mouth or throat.
- You run out of medicine before your next refill is due, or sooner than your healthcare provider says you should.
- You have questions or concerns about your condition or care.
