my husband has a history of high BP, is on medication, Valsartan-HCTZ 80-12.5mg, did not take it for two days, but took it this morning. Approx 1 hr ago, experienced dizziness and slid of the toilet onto the floor. I took his pressure 3 times, each time was in 80/53 range, which seems low to me. He also takes Flonase for allergies (stared about two weeks ago, Claritan didn t seem to help anymore). He is periodically breaking out in a sweat. He says he is not experiencing any pain.
