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 umeclidinium, causing hives, swelling around the throat and tongue, rash, and worsening of breathing problems. If this occurs, get emergency medical help at once.
Glaucoma: Umeclidinium 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 rhythm: Umeclidinium can cause changes to the normal rhythm of the heart, including an irregular heartbeat or rapid heartbeat. 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 umeclidinium, 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 other 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.
Worsening symptoms: If you find you need to use your short-acting ("rescue") inhaler more often or if your condition seems to worsen, call your doctor. If you have not been given instructions beforehand, contact your doctor immediately about what to do if any of the following situations occur (they may be signs of seriously worsening COPD):
- decreased effectiveness of short-acting, inhaled bronchodilators such as salbutamol, terbutaline, or fenoterol (less than 4 hours of relief)
- need for more inhalations than usual of short-acting, inhaled bronchodilators
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 umeclidinium passes 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.
The safety and effectiveness of using this medication have not been established for children or people under the age of 18.
