High blood pressure and dizziness should bring blood pressure down to normal values smoothly, and you can take antihypertensive drugs under the guidance of a doctor. If the blood pressure continues to rise and the dizziness does not ease, you should immediately call the emergency number and go to the hospital for a head CT or head MRI to clarify whether there is a cerebrovascular accident, including cerebral hemorrhage or cerebral infarction. Antihypertensive drugs should be selected according to different ages and different complications. If the patient is relatively young, with mild to moderate hypertension or combined with diabetes or coronary heart disease, various kinds of Prilosec or various kinds of Sartan can be used. If the blood pressure is high and the heart rate is increased, you can choose various kinds of Lolol. In older patients with hypertension, especially when systolic blood pressure is difficult to control, various diphenhydramine can be used. If the systolic blood pressure is persistently elevated in the elderly and the pulse pressure difference is relatively large, you can combine diuretics among antihypertensive drugs to lower blood pressure while taking other drugs.
