A rescue inhaler should be shaken before each use to properly mix the medicine with the propellant and ensure the correct dose is delivered. Typically, shaking is recommended for about 5 to 15 seconds, depending on instructions, and should be done every time before spraying a puff. This is especially important if the inhaler is new, hasn't been used for a few days or weeks, or has been dropped. Key details:
- Shake the inhaler hard for about 5 to 15 seconds before using.
- Shake before each puff, including subsequent puffs if multiple doses are needed.
- Shaking ensures the medication is properly mixed with the propellant.
- Always check specific instructions with the inhaler leaflet or healthcare provider.
This shaking step helps to prime the inhaler and guarantees the correct amount of medicine is inhaled during rescue use for asthma or breathing difficulties.
