Patient Information about XOPENEX Inhalation Solution

What is XOPENEX Inhalation Solution used for?
XOPENEX (zō-pen-eks) Inhalation Solution is used to treat or prevent narrowing of airways (bronchospasm) in patients 6 years of age and older with reversible obstructive airway disease, such as occurs in asthma or chronic obstructive pulmonary disease (COPD).

What are the symptoms of bronchospasm?
Symptoms of bronchospasm include: coughing, wheezing, chest tightness, and shortness of breath.

Important Safety Information:
Like other inhaled beta-agonists, XOPENEX Inhalation Solution can produce a narrowing of the airways called paradoxical bronchospasm, which may be
life-threatening.

Your healthcare provider may need to prescribe other medications in addition to XOPENEX Inhalation Solution to help control your asthma. Do not stop taking other asthma medications unless advised by your healthcare provider.

XOPENEX Inhalation Solution can cause significant heart-related side effects, such as an increase in pulse, blood pressure and/or related symptoms. If you have a heart condition, your healthcare provider will determine if XOPENEX is right for you.

Use as directed by your healthcare provider. Deaths have been reported with similar inhaled medications in asthma patients who use too much medication.

Hypersensitivity reactions (severe allergic reactions) may occur immediately after taking XOPENEX Inhalation Solution. If you experience itching, areas of skin swelling (angioedema), skin rash, or narrowing of the airways, these may be signs of a hypersensitivity reaction. Seek immediate medical attention if this happens.

If you find that treatment becomes less effective, your symptoms become worse and/or you need to use the product more frequently than usual, you should seek medical attention immediately.

If you currently have, or have had, a history of the following conditions, your healthcare provider will evaluate you to decide if XOPENEX Inhalation Solution is
right for you:

• heart disease (e.g., reduced heart circulation, high blood pressure, and irregular heartbeat)
• seizures
• high levels of thyroid hormone
• diabetes
• reactions to medications similar to XOPENEX Inhalation Solution

What should I tell my healthcare provider?
Review all medications that you are taking with your healthcare provider, including those that you take without prescription. Because of the potential to interact with XOPENEX Inhalation Solution and cause side effects, tell your healthcare provider if you are taking other medications such as:

• diuretics, such as furosemide and HCTZ (hydrochlorothiazide)
• antidepressants such as monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants
• drugs known to affect the heart's regular rhythm
• drugs used for high blood pressure or after a heart attack, such as metoprolol or atenolol

Tell your healthcare provider if you are trying to become pregnant, are already pregnant, or are nursing.
