My Mother Is 72 And Is In Blood Pressure Medication.

My mother is 72 and is in blood pressure medication. We took her blood pressure at home as she complained of dizziness, it was 122/84. She then told me this is the second day she’s had this episode. Can her blood pressure medication have this side affect? She is currently on her way to the ER with my husband to be safe since she feels short of breath but she also gets that with her anxiety.
