<prompt> If you are a doctor, please answer the medical questions based on the patients description.i have been taking norvasc 5mg for bp for a year . i haven t seen any change in my bp. my bp in my right hand is in the morning 14575. but in my left hand it is normal. after taking the medicine for one year i have experienced no side effects except lower heart beat of 48 to 52. i am 38. what should i do please?  <response>: Hello, I would explain that novas does not have any effects on the heart rate. As your blood pressure values are still above the normal ranges, I would recommend increasing the dose of novas to 10 mg daily and see if it helps improve your situation. I would also recommend performing a Doppler ultrasound of the carotid arteries in order to investigate for possible atherosclerotic plaques. Hope I have answered your query. Let me know if I can assist you further.
