Atrovent HFA (generic: ipratropium) is a prescription medication used to treat chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.

This medication belongs to a group of drugs called anticholinergics (or antimuscarinics) which work by opening up the air passages in the lungs to allow air to flow more easily, relieving symptoms such as coughing, wheezing and shortness of breath. 

Atrovent HFA comes in a metered-dose inhaler (called an "MDI"). It is usually taken as 2 inhalations four times a day.

Common side effects include headache, cough, dry mouth, and dizziness. Do not drive or operate heavy machinery until you know how it affects you.
