Hypertension is a common disease among middle-aged and elderly people. In order to use antihypertensive drugs rationally, patients should pay attention to the following points: Avoid using drugs without authorization. There are many kinds of antihypertensive drugs, and their effects are not exactly the same. Some antihypertensive drugs are effective for this type of hypertension, while others are effective for another type of hypertension. If you don’t take the right type of medication, the antihypertensive effect will not be fully realized, and sometimes you may mistakenly think that “antihypertensive medication does not work”. The drug treatment of hypertensive patients should be carried out under the guidance of a doctor, and should be graded according to the severity of the disease and individual differences. Benxi Railway Hospital Department of Internal Medicine Ren Zhongxiu Avoid lowering blood pressure too quickly. Some people once found high blood pressure, can not wait to immediately lower the blood pressure, arbitrarily increase the dose of drugs, it is easy to accident. It is best to lower blood pressure in the short term by no more than 20% of the original blood pressure, blood pressure is too fast or too low will occur dizziness, weakness, heavy can also lead to ischemic stroke and myocardial infarction. Do not use a single medication. In addition to mild or recent onset of hypertension, try not to use a single drug, but to combine drugs, compound treatment. The advantage is to produce a synergistic effect, reduce the dose of each drug, offset the side effects. Avoid taking medication without measuring blood pressure. Some patients usually do not measure blood pressure, only by self-perception to take drugs. If you feel unwell, take less, and if you feel dizzy, increase the dose. In fact, self-perceived symptoms and the severity of the disease is not necessarily the same, blood pressure is too low will also appear dizzy discomfort, continue to take drugs is very dangerous. The correct approach is to measure blood pressure regularly, adjust the dose in time, and maintain consolidation. Do not intermittently take antihypertensive drugs. Some patients take antihypertensive drugs when they stop, a high blood pressure to eat a few tablets, blood pressure a drop, immediately stop the drug. This intermittent medication, not only can not make the blood pressure stable, but also can make the development of the disease. Avoid asymptomatic not to take medication. Some patients with hypertension are usually asymptomatic and only find high blood pressure when their blood pressure is measured. After using the drug, dizziness, headache discomfort, simply stop the drug. If you don’t take your medication for a long time, your condition will worsen and your blood pressure will rise again, leading to cardiovascular and cerebrovascular disorders. The facts show that asymptomatic hypertension is not light, once discovered, should be under the guidance of a doctor to adhere to the medication, so that blood pressure is stabilized at a normal level. Do not take antihypertensive drugs before going to bed. Clinical findings show that taking antihypertensive drugs before bedtime can easily induce cerebral thrombosis, angina pectoris and myocardial infarction. The correct method is to take the drug 2 hours before bedtime.
