This medication should not be used in patients with allergic reactions to the active ingredient or excipients. It may exacerbate symptoms in patients with severe bronchial asthma or chronic obstructive pulmonary disease, and should not be administered to them. It is also not suitable for patients with diabetic ketoacidosis or metabolic acidosis. Patients with very slow heart rates (bradycardia), heart conduction disorders, or cardiogenic shock should not use this medication. Patients with pulmonary hypertension causing right heart failure or congestive heart failure, severe hypotension, or advanced peripheral circulation disorders may also be at risk when taking this medication. It should not be administered to patients with thyroid dysfunction or untreated pheochromocytoma as it may adversely affect them. Patients susceptible to bronchial asthma or bronchospasm should be closely monitored when using this medication alongside bronchodilators. Patients at risk of congestive heart failure should use cautiously while regularly checking heart function. Diabetics or patients with hypoglycemia should monitor blood sugar levels closely, as symptoms of hypoglycemia may be masked. Patients with severely impaired liver or kidney function, pheochromocytoma, and the elderly should start at a lower dosage and be closely observed. This medication may cause allergic reactions such as skin rashes, itching, hives, and angioedema; discontinuation is needed immediately if symptoms appear. Symptoms like reduced tear secretion, vision disturbances, or dry eyes may occur, and consultation with a doctor is advised if any abnormal symptoms appear. Cardiac-related side effects like slow heart rate, hypotension, symptoms of heart failure, and cold extremities should be monitored carefully. Neuropsychiatric side effects such as confusion, dizziness, drowsiness, insomnia, and headaches may occur, so it is advisable to avoid driving or handling dangerous machinery. Gastrointestinal tract symptoms such as nausea, vomiting, diarrhea, and abdominal pain may occur; consultation with a doctor is recommended if symptoms are severe. Respiratory side effects like wheezing or bronchospasm may occur rarely, hence asthmatic patients should take extra care. Regular testing and observation are required since this medication may impact liver and kidney functions. If taken for extended periods, regular monitoring of heart function and blood pressure, pulse, etc., is necessary, and discontinuation should not be abrupt but should occur gradually under medical advice. Patients scheduled for surgery must stop taking this medication 24 hours prior, and it is important to use anesthetics that minimize cardiac suppression during anesthesia. Dizziness may occur at the initial intake of this medication; avoid driving or engaging in risky tasks. Caution is advised when used with other medications, particularly diabetes treatments, calcium channel blockers, sympatholytics, and anesthetics due to many interaction potentials. During pregnancy, it should be used cautiously under a physician's supervision as it may affect the fetus; breastfeeding should be avoided or this medication should be avoided during lactation. Safety in children has not been sufficiently established, so it should be administered carefully in pediatric cases. Elderly patients should start at a lower dose and be closely monitored, as overdose can lead to severe side effects requiring immediate medical attention.
