I may have accidentally taken 2 of my husband s lisinopril last night before bed thinking it was my prescription. (The pills look almost identical). I m 9 weeks pregnant and breastfeeding my 18 month old. I was extremely dizzy when getting up during the night and into the morning. It wore off by noontime. I thought it was just part of the pregnancy until I went to take my medicine tonight and grabbed my husband s and realized I may have not noticed the night before. Should I be worried?? Is it out of my system by now? I m calling my doctor tomorrow, but kinda freaking out tonight.
