PRECAUTIONS: Before using this medication, tell your doctor or pharmacist if you are allergic to budesonide or formoterol; or if you have any other allergies.Before using this medication, tell your doctor or pharmacist your medical history, especially of: high blood pressure, bone loss (osteoporosis), depression, diabetes, eye problems (e.g., cataracts, glaucoma), heart problems (e.g., angina, irregular heartbeat), any recent infection, liver problems, overactive thyroid (hyperthyroidism), seizures, smoking.Budesonide/formoterol may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using budesonide/formoterol, tell your doctor or pharmacist if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using budesonide/formoterol safely.Avoid exposure to chickenpox or measles infection while using this medication unless you have previously had these infections (e.g., in childhood). If you are exposed to one of these infections and you have not previously had it, seek immediate medical attention.If you have switched from an oral corticosteroid (e.g., prednisone tablets) to this inhaler within the past 12 months, or if you have been using this product in higher-than-usual doses and suddenly stop using it, your body may not produce enough natural steroids. You may need to start taking additional corticosteroids, especially if your body is stressed due to a major infection, surgery, or injury. Deaths due to low steroid levels have sometimes occurred during such stresses. Tell your doctor immediately if any of the following side effects occur: unusual/extreme tiredness, weight loss.Consult your doctor or pharmacist for more details, and tell them that you use (or have used) any type of corticosteroid. Carry a warning card or medical ID bracelet that identifies your need for oral corticosteroids during times of stress. Consult your doctor or pharmacist now for specific advice about stress situations. You may need to carry a supply of corticosteroid tablets as a precaution.Caution is advised when using this drug in children because there is a slight risk that it may temporarily slow down a child's growth rate, but this will probably not affect final adult height.
