hctz (?) Have been on all for months. Card. added norv. 2 months ago & a wk ago added lis. BP is running very low for me as low as 106/54 at times though aver. 122/74. Heart rate has jumped to high 90s & 114+ the past day or 2. Could it be caused by the lis. or maybe H1N1 vaccine given yesterday? Feel a little fainty at times, although I don't pass out. Not dizzy just feel like I may faint--not just upon standing-even sittting still.
