I was taking 25 mg Metoprolol Tartrate and 2.5mg Amlodipine Besylate both twice a day. They are both for reducing blood pressure. the Amlodipine does not lower your heart rate like the Metoprolol does. My calves were mildly swollen from the Amlodipine. I had two incidents where my calves were hard as rocks.
I stopped the Amlodipine. The cardiologist said he was Ok with this but if my blood pressure goes over 140 take one Amlodipine. My systolic gets high but not my diastolic-usually in the 50's. My heart rate is usually in the 50's. My previous cardiologist told me since the diastolic was low not to take the metoprolol if the systolic goes below 120.
The generally accepted medical practice is to hold the Metoprolol is systolic is 110 or below or the heart rate is 60 or below. If I followed this for my heart rate I would never take it.
How high does your systolic get? Are you off all salt?
There are other drugs to lower it.
