Mastering Inhaler Technique: Step-by-Step Guide
Using your inhaler with the correct technique ensures that prescribed medication reaches deep into your bronchial airways rather than lingering in your mouth or throat. Proper coordination, breath control, and device care maximize symptom relief and minimize side effects like hoarseness or oral thrush. This guide provides clear, practical steps for correctly administering a standard metered-dose inhaler.
Quick Summary
Stand upright, exhale completely, press the inhaler while taking a slow, deep breath over 3 to 5 seconds, and hold your breath for 10 seconds to deliver medicine deep into your lungs.

Step-by-Step Guide
Prepare and Prime the Device
Remove the protective cap from the mouthpiece and inspect the opening to ensure it is free of lint, dirt, or foreign objects. Shake the inhaler vigorously up and down 4 to 5 times to thoroughly mix the active medication with the propellant. If using the inhaler for the first time or if it has sat unused for several days, prime it by releasing the recommended test sprays into the air away from your face.
Important: Never skip shaking the canister, as unmixed propellant will deliver an inaccurate and ineffective dose of medication.
Sit or Stand Up and Exhale Completely
Sit up straight or stand to allow your diaphragm and chest wall full space to expand. Turn your head slightly away from the inhaler and gently breathe out through your mouth until your lungs feel completely empty. Emptying your lungs fully creates the necessary negative pressure to pull the aerosol deep into your lower airways.
Position the Mouthpiece and Create a Tight Seal
Bring the inhaler to your mouth upright, with the canister pointing upward and the mouthpiece between your teeth. Rest your tongue flat along the floor of your mouth so it does not obstruct the spray orifice. Close your lips firmly around the mouthpiece to form an airtight seal, or attach a spacer device if one has been prescribed.
Important: Do not block the mouthpiece opening with your tongue or bite down firmly with your teeth.
Press the Canister and Inhale Slowly and Deeply
Begin breathing in slowly and steadily through your mouth. Just as you start your inhalation, press the metal canister down firmly once to release a single puff of medication. Continue inhaling smoothly and deeply over a count of 3 to 5 seconds until your lungs are completely filled with air.
Important: Avoid breathing in too quickly or abruptly, as fast air velocity causes medication particles to slam into the back of your throat instead of traveling to the lungs.
Hold Your Breath for 10 Seconds
Remove the mouthpiece from your mouth and close your lips. Hold your breath for up to 10 seconds, or for as long as is comfortably possible without straining. This brief pause allows the microscopic aerosol droplets to settle onto the walls of the small airways rather than being immediately blown out.
Exhale Gently and Wait Before a Second Dose
Breathe out gently and normally through your nose or mouth. If your prescription calls for a second puff, wait approximately 30 to 60 seconds before repeating the steps, especially when using rapid-acting bronchodilators like albuterol. This pause allows your bronchial passages to begin relaxing and gives the metering chamber time to refill accurately.
Rinse Your Mouth (For Inhaled Corticosteroids)
If your inhaler contains a steroid medication, swish water vigorously around your mouth and gargle at the back of your throat, then spit the liquid into the sink. Replace the protective cap on your inhaler mouthpiece to keep it clean. Regular rinsing prevents localized steroid buildup that can lead to fungal infections.
Important: Always spit the water out; swallowing the rinse water increases systemic absorption of the steroid into your bloodstream.
