Dizziness caused by excessive fatigue may be due to brain nerve dysfunction, or to insufficient blood supply to the brain due to cerebral vascular spasm induced by excessive fatigue, or to elevated blood pressure. If you want to alleviate the above problems, patients should get more rest and avoid emotional excitement, in addition to symptomatic treatment for the cause. For example, it is recommended to use cerebrovascular dilation drugs to improve blood circulation in the brain and improve dizziness symptoms. Patients can be given oral flunarizine hydrochloride capsules, haematocrit tablets, vermifugin capsules and ginkgo biloba drops to improve the symptoms. If it is caused by elevated blood pressure, patients are advised to take antihypertensive drugs, such as temisartan, while resting, so that the symptoms can be improved after the blood pressure drops.
