If you are also using a bronchodilator (a drug that opens the airways to improve breathing), use it first before using the beclomethasone inhaler. This will allow more beclomethasone to reach your lungs. Bronchodilators include albuterol (Proventil, Ventolin), pirbuterol (Maxair), bitolterol (Tornalate), and others.
There may be other drugs that can interact with beclomethasone inhalation. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
