It is foolish and dangerous to give medical advice without knowing your medical history and without a physical examination.

Make a long-distance call to your Physician and ask.

Since Metoprolol is a beta blocker, it not only lowers your blood pressure, but can lower your heart rate as well. It would be dangerous of us to advice you on the increased use of this medication. You need to be seen in person by a medical practitioner.
