The safest blood pressure medication depends on your age, blood pressure level, kidney function, diabetes status, heart health, and other medical conditions. Different people may need different medicines, so treatment should be selected by a doctor after checking your blood pressure and overall health, rather than starting tablets on your own. Commonly prescribed blood pressure medicines help relax blood vessels, reduce pressure on the heart, or remove extra salt and fluid from the body. Taking the wrong medicine or dose without supervision may cause dizziness, fainting, swelling, or very low blood pressure. Along with medicines, reducing salt intake, regular exercise, maintaining a healthy weight, good sleep, avoiding smoking, and managing stress can help naturally control blood pressure. Seek urgent medical care if you develop severe headache, chest pain, breathing difficulty, weakness, blurred vision, or very high blood pressure readings.
