Mother age 83 recently was changed from Lisinipril to Losartin. She also takes Levityhroxine, Metformin, and Glimepride (sp). She has experienced light-headedness, feeling of hot at times very close led at others, her BP has fluctuated from 124/58 to 181/76 during one of the two ones I ve had her at the ER. Both ER visits stayed they find nothing emergent . She is currently experiencing hot, rapid heartbeat, tingling, light numbness in feet and legs. I am at a loss as to what to do.
