It is a misconception that hypertension medications should be changed every few years. If a medication controls blood pressure well and there are no adverse effects, it is not necessary to change the medication. A drug that controls blood pressure can be taken for a long time, and it is not recommended to change the drug frequently. If there is poor blood pressure control after a few years of taking the medication, it is necessary to increase the dosage on top of the original one or combine it with other medications for treatment. Commonly used antihypertensive drugs include chlorosartan, captopril, hydrochlorothiazide, metoprolol and so on. While taking antihypertensive drugs, patients should pay attention to improving their lifestyle. Diet should be less high salt food, more vegetables and fruits to prevent further progression of hypertension, and also appropriate sports and exercise. The increase, decrease or adjustment of medication should be done under the guidance of a physician.
