Is it okay to take blood pressure medication before a health check-up if I have high blood pressure?

The family member takes blood pressure medication in the morning because they have high blood pressure.
You had a health check-up in December, and you were told not to eat anything in the morning before the examination.
They also told me not to take the blood pressure medication.
Maybe that's why my blood pressure was high during the health check-up~
You also had an endoscopy while your blood pressure was high.
I don't think it's good to have a check-up while my blood pressure is high.

If the check-up is in the morning and you cannot take your blood pressure medication in the morning, is it okay to take it after dinner the night before?
