Brief Answer:
antihypertensives need 2-4 weeks to achieve full effect

Detailed Answer:
Hello,

most antihypertensives require 2-4 weeks to reach their full effect on blood pressure. I haven't understood the dose of benazepril you were taking and the new dose that your doctor prescribed. You've mentioned that you've just started 4mg benazepril and then you say that your doctor reduced benazepril to 5mg. Please clarify...

102mmHg is below the usual target level for the systolic blood pressure. When a patient receives antihypertensive treatment the target level for systolic blood pressure is approximately 130mmHg unless the patient has an aneurysm or serious heart disease. The blood pressure may fluctuate and having 102 at some time is not a bad thing (unless it causes symptoms). Having 102 most of the time is not good though because higher reductions in blood pressure have been associated with worse outcomes regarding cardiovascular diseases.

Kind Regards!

Brief Answer:
it has to be tested to find out...

Detailed Answer:
I see. So your doctor reduced the dosage based, having the same thoughts with me I guess, that levels close to 102mmHg are too low. The results on your blood pressure would be almost immediate when you reduce the dosage but the final blood pressure will be evident after a couple of weeks.

Whether 5mg would be sufficient or not will have to be proved. Blood pressure control requires a trial and error process. Usually with such small reductions we expect no more than 10mmHg differences in blood pressure but it depends on many factors.

So in conclusion, I agree with your doctor's decision to suggest a lower dosage of the antihypertensive. Measuring your blood pressure for the next couple of weeks is your best next step to help the doctor assess the effects of this change.

Kind Regards!
