Taking it with meals slows the rate of absorption and may reduce the incidence of orthostatic hypotension.

This medication should not be used in certain patients. For example, it should not be administered to individuals who are allergic to this medication or its components, those with severely impaired cardiac function, those with significant heart conduction disorders, patients with cor pulmonale, and patients with metabolic issues due to diabetes.

When taking this medication, symptoms such as dizziness, headache, and fatigue may occur, and rarely, psychiatric abnormalities or cardiac-related side effects may manifest. It is essential to receive regular heart function assessments as blood pressure may drop too low or heart rate may slow. Pregnant or breastfeeding women should not take this medication, as it can have severe effects on the fetus or newborn. This medication can interact with other drugs, so if you are taking any other medications, you must inform your doctor or pharmacist. Especially when taken with antihypertensives, antidiabetics, cardiac medications, sedatives, or antidepressants, the risk of side effects may increase. Sudden discontinuation of the medication can worsen symptoms, so the dosage should be gradually reduced according to the doctor's instructions.
