I am here to address your concerns and provide great service.
You should not take verapamil with metoprolol --serious interaction.
Not a correct suggestion.
The evening dip in blood pressure is due to the long actin medications you are on.
Quinapril, HCTZ and hydralazine together have potent effect.
Since you likely take these medications in morning, they can cause drop in the blood pressure in the evenings.
One good option will be to switch quinapril to the night time.
That way your blood pressure in the morning will be lower.
This is just the blood pressure medication dose and timing related issue nothing else.
Please discuss with your doctor.
It was my pleasure to help you today.
