Hi, Welcome to HCM.
Antihypertensive medications are usually titrated based on your blood pressure and how resistant it is. Thus your treatment regimen, including the dosage of your individual medication, will be different compared to other patients so it will be difficult to judge whether or not the dose of
metoprolol you are receiving is high just based on absolute amount you are taking.
Furthermore, it will be worthwhile to compare your blood pressure before and after you began taking
norvasc to understand how much did your blood pressure decease. Looks like your blood pressure at this time is in the normal range, however should it reduce further then I will advise that you consult your primary physician to titrate your antihypertensive medication again.
Also based on the information you have given, looks like your
body mass index is 29 kg/sq. m (normal: 19 to 25 kg/sq. m). This means that your weight is higher and it can contribute to your
hypertension significantly. I will recommend lifestyle changes such as diet control and exercise, restriction of smoking/alcohol/caffeine if any. This will certainly help control your blood pressure as well.
Hope this helps.
