Aclidinium is a bronchodilator.

Aclidinium is used to prevent bronchospasm in adults with chronic bronchitis, emphysema, or other forms of COPD (chronic obstructive pulmonary disease).

Aclidinium may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Aclidinium is not a rescue medicine. It will not work fast enough to treat an asthma attack. Use only a fast acting inhalation medicine for an asthma attack.

Aclidinium is a powder that comes with a special inhaler device preloaded with measured doses of this medicine. The device delivers a single dose each time you press a button on the inhaler.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Aclidinium should be used at evenly spaced intervals, usually every 12 hours.

Use aclidinium regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.

Call your doctor or seek medical attention if you think your fast-acting inhaler medications are not working as well.

Store at room temperature away from moisture and heat. Keep this medicine in the sealed pouch until ready to use. Do not store the inhaler device on top of any surface that vibrates.

Throw the inhaler device away 45 days after you have taken it out of the sealed pouch, or if the dose indicator shows a zero or the device locks, whichever comes first. Each inhaler device contains 60 doses.
