It is not recommended to drink alcohol after taking antihypertensive drugs. If you must drink alcohol, the time of taking antihypertensive drugs and drinking alcohol should not be close to each other, and it is relatively safe to drink a small amount of alcohol after 1-1.5 hours. Drinking alcohol increases capillary permeability and vasodilation, and most patients will experience a transient decrease in blood pressure. Therefore, drinking alcohol will cause a drop in blood pressure, and if you then take antihypertensive drugs will lead to a significant drop in blood pressure or instability, and may also cause sudden hypotension in serious cases, leading to fainting, falls and accidental injuries. Therefore, hypertensive patients should try not to drink alcohol while taking medication. Patients with hypertension should take antihypertensive drugs regularly. On the basis of the application of antihypertensive drugs, patients are advised to measure their blood pressure regularly, usually once a day in the morning and evening. In addition, patients with hypertension need to improve bad habits on the basis of regular medication, strictly quit smoking, limit alcohol consumption, regular work and rest, do not stay up too late, relax emotionally, eat less salt and oil, and exercise regularly to improve body weight.
