Patients whose blood pressure is normal in the morning and high in the afternoon may consider that it is because the current regimen of antihypertensive medication is not well suited for them. For such patients, antihypertensive medications can be taken in the afternoon to help better control blood pressure. Some patients may have high blood pressure mainly in the afternoon. Some patients feel that their blood pressure is higher in the afternoon, but in fact, this is in line with the law of blood pressure fluctuation, which is that 6-10 am and 4-8 pm are the two peak periods of the day when blood pressure is higher. If it is at night, then it is relatively low blood pressure period of the day. There may also be some patients who find that their blood pressure rises in the afternoon when they have their blood pressure measured.
