high blood pressure
"Been taking Benicar/HCT for several years now. It is a very effective antihypertensive in this combination. As they say, nothing in life is free. While it does a great job of lowering my blood pressure, I have experienced several bothersome side effects. These include lightheadedness, dizziness and sleepiness. The later may be due to the potent antihypertensive action of the combination. Tried cutting the pill in half, but since it is not scored, really don't know how much medicine I am getting in the split piece."
