Will OTC sleeping pills increase or decrease blood pressure and pulse?

anything that makes you sleep will, that's why there are warnings on the boxes.

BP has to do with fluid volume and peripheral resistance of arteries and veins. Does not affect pulse, but can be affected by pulse. BP is the amount of fluid being pumped and how big the "pipes" are. Heart rate and pulse rate are the same in a healthy person. Heart rate is the amount of pumps per minute, BP is the amount of fluid pumped through the size of the arteries. Low fluid or big arteries lowers BP, high fluid or constricted arteries equals high BP.
