If a patient with high blood pressure forgets to take their medication, it is usually important to monitor the patient’s blood pressure, and if it is very high, a temporary tablet of a short-acting antihypertensive medication such as captopril or nifedipine can be taken. If the blood pressure is within the normal range or mildly elevated, the patient does not need to take the medicine temporarily when he/she forgets to take it, and will continue to take the medicine normally next time he/she needs to take it, without having to replenish what he/she has forgotten, or to take more or additional supplements, but only need to take the antihypertensive medicine normally within the next time he/she takes the medicine normally. If you take antihypertensive medication once a day, and you forget to take it in the morning, you can monitor your blood pressure in the afternoon, and if your blood pressure is normal from the afternoon to the evening, you can take it in the normal time on the morning of the second day. However, if your blood pressure is not normal in the afternoon, you can take the antihypertensive medication you forgot to take in the morning in the afternoon and continue to take it on the 2nd day according to the previous schedule.
