What happens if you drop an inhaler such as Symbicort? Is it permanently broken and do you need a replacement?
In most cases it is probably fine.
It may be broken if there are obvious cracks and all the parts no longer work together, or you hear funny sounds when trying to operate the device. However, if everything looks and works okay, there is often nothing to worry about.
Most inhalers are actually quite sturdy and well built. They are specifically designed to be quite resilient as they are prescribed to hundreds of millions of people who use them in very diverse circumstances.
