The use of asthma inhalers can be challenging. With a Spacer, Side Effects are Reduced.
Numerous studies have demonstrated that even with the best instruction on how to use an inhaler (holding the device directly up to your mouth), a significant amount of the drug still ends up reaching the tongue rather than the lungs. As a result, an inhaler may have more negative effects and fewer positive ones. Using a spacer, a piece of plastic that fits between the inhaler and your mouth and allows the medication to fully aerosolize so that it can be drawn into the lungs, is the simplest approach to get more medicine inhaled.
