The medication comes in a metered-dose inhaler that contains 200 inhalations, with 90 mcg of Proventil per inhalation. Some people use the Proventil inhaler only when they need it during an
asthma attack, while others use it regularly to help prevent attacks.
Proventil works by stimulating beta receptors in the body, causing the muscles around the airways to relax. This action opens up the airways and allows more air to get into and through the lungs, which can help with bronchospasms and
asthma attacks.
While most people tolerate the Proventil inhaler well, side effects are possible. Some of the most commonly reported side effects include nausea, heart palpitations, tremor, and fast heart rate.
