What are the blood pressure medications with no side effects?

At present, there is no antihypertensive medication that is completely free of side effects. While various antihypertensive drugs exert their blood pressure-lowering effects, they may also be associated with certain side effects. Commonly used antihypertensive medications include calcium channel blockers (e.g., nifedipine, amlodipine), diuretics (e.g., hydrochlorothiazide, furosemide), β-blockers (e.g., metoprolol, atenolol), angiotensin-converting enzyme inhibitors (e.g., captopril, enalapril), and angiotensin II receptor blockers (e.g., irbesartan, valsartan). When selecting an antihypertensive medication, patients should, under the guidance of a physician, comprehensively consider and weigh the risks and benefits based on their individual medical conditions, physical status, drug tolerability, and other factors to choose the most suitable medication. Meanwhile, during treatment, patients should closely monitor their physical condition and promptly seek medical attention and inform their physician if any discomfort occurs.
