Beclometasone is a corticosteroid medication used to reduce inflammation and allergic reactions in the body. It is commonly prescribed in inhalers for the long-term management of asthma and other respiratory conditions, helping to prevent symptoms such as wheezing, shortness of breath, and chest tightness. Beclometasone is also available as nasal sprays, creams, and ointments to treat allergic rhinitis and various inflammatory skin disorders by suppressing the immune response and decreasing swelling, redness, and irritation.
