This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: cardiogenic shock, certain types of irregular heartbeats or heart rhythms (e.g., severe sinus node dysfunction resulting in marked sinus bradycardia, second or third degree atrioventricular block, bradycardia with associated syncope except when a pacemaker is used). Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, heart problems (e.g., congestive heart failure, low blood pressure), lung diseases, thyroid problems, upcoming major surgery, electrolyte problems such as low potassium or low magnesium.

A preservative (benzyl alcohol) which may be found in this product or in the liquid used to mix this product (diluent) can infrequently cause serious problems (sometimes death), if given in large amounts (more than 100 mg/kg daily) to an infant during the first months of life (neonatal period). The risk is also greater with low birth weight infants. Symptoms include sudden gasping, low blood pressure, or a very slow heartbeat. Report these symptoms to the doctor immediately should they occur. If possible, a preservative-free product should be used when treating neonates.
