If the high blood pressure after vaccination is caused by physiological factors such as excessive tension and adverse drug reactions, the effect of lowering blood pressure can be achieved after rest. If it is caused by primary hypertension, renal disease and other diseases unrelated to the vaccine, take medication for the cause of the disease to reduce blood pressure, and it is not recommended to reduce blood pressure quickly. 1. Physiological factors: before the vaccine, if the patient is overly nervous, it may lead to greater emotional fluctuations, the situation of elevated blood pressure or the adverse reaction of the vaccine, which may lead to a temporary increase in blood pressure. Generally there is no need to take special therapeutic measures, after a period of rest, the blood pressure can be restored to normal by itself. 2. Primary hypertension: High blood pressure after vaccination may be caused by primary hypertension. Patients can take oral nifedipine, verapamil and other calcium channel blockers under the guidance of doctors. After standardized treatment, the blood pressure can be lowered. 3. Kidney disease: high blood pressure is also considered to be secondary hypertension caused by kidney disease, such as glomerulonephritis patients will have hypertension, edema and other symptoms. Patients can follow the doctor’s instructions to treat the primary disease and oral antihypertensive drugs, such as captopril, benadryl, etc., or oral diuretics, such as torasemide, furosemide, etc., which can lower blood pressure. If the patient himself suffers from high blood pressure and other diseases, need to consult the doctor in time, under the guidance of the doctor to take appropriate treatment measures.
