—My medications are Metoprolol (50mg twice daily) and Losartan (25mg once daily). The Metoprolol dosage was an increase which my physician prescribed about three years ago. My question is this: Does anyone her take a higher dosage of Metoprolol (or another beta-blocker)? My most troubling symptom is dizziness, sometimes feeling near-fainting. (A fainting episode ten years ago is what first sent me to the doctor.) Lately, the dizziness has gotten a bit worse. Was wondering if an increased dosage has helped anyone with this symptom.
