Concerns related to adverse effects:

Use with caution in patients with a history of hypersensitivity to atropine; aclidinium has a similar structure to atropine.

• Glaucoma: Use with caution in patients with narrow angle glaucoma; may worsen symptoms. Monitor for signs/symptoms (eg, eye pain/discomfort, blurred vision, visual halos or colored images associated with red eyes from conjunctival congestion and corneal edema).

• Myasthenia gravis: Use with caution in patients with myasthenia gravis; may worsen symptoms.

• Prostatic hyperplasia/bladder neck obstruction: Use with caution in patients with prostatic hyperplasia and/or bladder neck obstruction (eg, dysuria, difficulty in passing urine); may worsen symptoms.
