AirSupra Shaking Instructions
You should shake your AirSupra inhaler for 5 seconds immediately before each use, with minimal delay between shaking and actuation.
Proper Shaking Technique
Shake the inhaler vigorously for 5 seconds before each actuation to ensure consistent drug delivery and proper dose emission 1.
Actuate immediately after shaking (within 1-2 seconds) to prevent dose variability 1.
Shake again before each subsequent puff if taking multiple doses, as delays between shaking and actuation can significantly alter the emitted dose 1.
Why Timing Matters
Research demonstrates that delays between shaking and actuating a suspension inhaler dramatically increase the emitted dose of the second actuation 1.
A 10-second delay results in 147% of the intended dose, a 20-second delay yields 187%, and a 30-second delay produces 227% of the nominal dose 1.
The mean delay in real-world use is approximately 13 seconds, which can result in 159% of the intended dose being delivered 1.
Complete Administration Sequence
- Shake vigorously for 5 seconds 1
- Actuate immediately (within 1-2 seconds of shaking) 1
- Inhale slowly over 5 seconds during actuation 2
- Hold breath for 10 seconds after inhalation 3, 4
- If a second puff is needed, shake again for 5 seconds before the next actuation 1
Common Pitfalls to Avoid
Never shake once for multiple puffs - this is the most common error and results in unpredictable dosing 1.
Avoid rapid inhalation (faster than 5 seconds), as this reduces bronchodilator effectiveness 3, 4.
Do not hold breath for less than 10 seconds, as shorter breath-holding (4 seconds) reduces bronchodilation 3, 4.
Never delay actuation after shaking, especially when using a valved holding chamber with children, as caregivers frequently make this error 1.
