Following open heart surgery, I was put on Metoprolol. I was tried all the time and had strong head rushes and fainting spells. Recently I was changed to Verapamil as this was believed to have less impact on my lungs. I continued to have bad head rushes and fainting spells. Some of the faints were serious.
I take a water pill and I may have over did it. My doctor said the problem was dehydration. I tried to regulate the amount based upon the swelling in my ankles. I now allow some swelling in my ankles but continue to have the fainting spells. My doctor now believes it is due to low blood pressure. My home readings have been in the 165/95 range.
I now make sure I take plenty of fluids and exercise and stretch before getting out of a seat or out of bead. So far so good.
