Why does your nebulizer make you sleep?

A nebulizer itself doesn't directly cause sleepiness, but the medications used in the nebulizer, such as bronchodilators or steroids, can have sedative effects in some individuals. Additionally, the soothing process of inhalation therapy can promote relaxation, leading to drowsiness. If you experience significant sleepiness after using a nebulizer, it's important to consult your healthcare provider to ensure the medication is suitable for you.
