How does this medication work? What will it do for me?
This product is a combination of two medications: aclidinium and formoterol. Aclidinium belongs to the class of medications called long-acting muscarinic antagonists. Formoterol belongs to the class of medications called long-acting beta2-agonists. Aclidinium - formoterol is used as long-term maintenance to keep the airways open for people with chronic obstructive pulmonary disease (COPD) including chronic bronchitis and emphysema.
Aclidinium and formoterol work by different means to relax the muscles that surround the airways. This opens the air passages, allowing more air to get to the lungs, and makes breathing easier.
Aclidinium - formoterol should not be used as a rescue medication to relieve sudden attacks of COPD symptoms such as wheezing or shortness of breath. Consult your doctor or pharmacist for advice about rescue medications that are appropriate for you.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergy: In rare cases, immediate allergic reactions may occur after using aclidinium - formoterol, causing hives, swelling around the throat and tongue, rash, and worsening of breathing problems. If this occurs, seek emergency medical help at once.
Asthma: This medication has not been studied for the treatment of asthma. The use of medications similar to formoterol to treat asthma, without a long-term control medication such as a corticosteroid increases the risk of asthma-related death.
Diabetes: This medication may cause an increase in blood sugar levels (may cause a loss of blood glucose control) and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication.
Glaucoma: Aclidinium may cause symptoms of glaucoma (increased pressure in the eyes), such as blurred vision or eye pain or pressure to become worse. If you have glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Heart conditions: Medications like aclidinium and formoterol may have effects on the cardiovascular system (heart and blood vessels). Effects such as chest pain, rapid or pounding heartbeat and changes to blood pressure have been linked to these medications. If you have a history of heart attack, angina or high blood pressure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Heart rhythm: Aclidinium - formoterol can cause changes to the normal rhythm of the heart, including an irregular heartbeat called QT prolongation. QT prolongation is a serious life-threatening condition that can cause fainting, seizures, and sudden death. If you are at risk for heart rhythm problems (e.g., people with heart failure, angina, low potassium or magnesium levels), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Inhalation-induced bronchospasm: Inhaled forms of medications may cause spasms of the airways, which make breathing difficult. If you experience this problem when using aclidinium - formoterol stop using this medication immediately. Speak to your doctor if you experience any problems with breathing while taking this or other inhaled medication.
Smoking: If you smoke, discuss with your doctor or pharmacist the benefits of stopping smoking. Smoking contributes to the symptoms of COPD. People who stop smoking often see a significant improvement in their breathing symptoms.
Urinary tract problems: This medication can cause the symptoms of some urinary tract problems to become worse. If you have an enlarged prostate or another condition that causes urination to be difficult, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if aclidinium or formoterol pass into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
