33 yr old/female. dizziness and lightheaded. taking allegra d, symbicort (budesonide and formoterol) and pro-air. blood pressure 95/60. why dizziness?

BP a bit low: Your BP is a bit low which maybe causing your dizziness. If the dizziness occurs often from rapid change of position from laying to sitting or standing , then likely it is due to low bp. If dizziness associated with change of head position/rapid rotation or up/down position, it is possibly vertigo. Keep well hydrated and take it easy for couple of days. If not better, consult doc. Good luck.
