Blood pressure 105/63mmHg normal after taking antihypertensive drugs. 1. The blood pressure control target of hypertensive patients is ≤130/80mmHg, and the blood pressure level of 105/63mmHg is relatively low. Low blood pressure can easily cause insufficient blood perfusion to the heart, brain and other important organs, resulting in dizziness, fatigue and other discomforts. 2. If there is no discomfort, oral saline can be taken to replenish body fluids, and at the same time, antihypertensive drugs can be continued for observation. 3. If dizziness, fatigue and other discomforts occur or blood pressure continues to fall and other symptoms, you should consult a doctor in time and follow the doctor’s instructions to temporarily stop or reduce the medication, and at the same time pay attention to lying down and resting to avoid causing insufficient blood supply to the heart and brain, and then continue to take the medication when the blood pressure is restored to the normal level. If the blood pressure does not return to normal in a short period of time after the above treatment, the dosage of the medication can be adjusted under the guidance of a physician to maintain the blood pressure at the optimal level. It is also recommended to exercise moderately, eat a well-balanced diet, monitor blood pressure regularly, and take medication regularly to avoid excessive fluctuations in blood pressure.
