<human>: I had three stents put in 5/6 years ago.  I have never had high blood pressure or high cholesterol, but the Cardiologist that inserted my stents insists that I take Simvastatin, and Niacin for cholesterol and Atacand for blood pressure.  Lately, I have been getting light headed and my blood pressure (we have a home device) ranges from 110/60 to 135/78.  Without my Cardiologists permission Im cutting my Atacand in half, but still feel light headed.  Advice (beyond, go see your Cardiologist?
<bot>: Hello, If you were not hypertensive before, then you can stop your Atacama and see if your symptoms improve. But by that time, you need to monitor your blood pressure daily for a week, and if it stays below 140/90 mmHg, then there's no need to start Atacama back. I would also like to advise you to check your serum electrolyte level as electrolyte imbalance due to medicines can also produce symptoms like these. Hope I have answered your query. Let me know if I can assist you further.
