Overdosing on this medication can lead to excessively low blood pressure, so the prescribed dosage must be strictly observed. When starting the medication or significantly increasing the dose, dizziness or lightheadedness may worsen; avoid hazardous activities such as working at heights or driving. Before taking this medication, inform your doctor about any other antihypertensive medications you are taking and closely monitor blood pressure changes. Particularly when taking diuretics or PDE5 inhibitors together, caution is needed as blood pressure-lowering effects may be intensified.
