How does an inhaler work?

Bronchodilators, or most commonly called inhalers, are medications that are breathed through the mouth and into the lungs to help relax muscles that tighten around your airways. The medicine helps open the airway and lets more air move in and out of your lungs and helps you breathe more easily.

Can I drink water after inhaler?

If you are using a corticosteroid inhaler, gargle and rinse out your mouth with water after use. Do not swallow the water. Swallowing the water will increase the chance that the medicine will get into your bloodstream. This may make it more likely that you will have side effects.
