Clenil Aerosol is a prescription medication used to treat asthma and other respiratory conditions. The aerosol form allows the medication to be delivered directly to the lungs, providing fast relief and long-term control of symptoms such as wheezing, shortness of breath, and chest tightness. This medication works by decreasing the swelling and irritation in the airways, preventing asthma attacks, and improving lung function over time. It is typically used as a maintenance treatment to manage chronic asthma or as part of a comprehensive asthma management plan.
