The medicine is a type of beta agonist that works by stimulating beta receptors in the body, including those on the muscles around airways. This action causes the muscles to relax, which opens up the airways and allows more air to get into and through the lungs.
It is important to talk to your healthcare provider before using the Proventil HFA inhaler if you have
