high blood pressure
"After my cardiologist tried me on many different combinations of Blood Pressure medications over a period of 3 years, Diltiazem worked perfectly. I'm on the maximum dosage allowed, but take it twice a day in different dosages.  With Hyzaar 100/12.5 at breakfast, I take 240 mg of Diltiazem.  With dinner, I take 300 mg of Diltiazem.  I have had no side effects that I'm aware of.  Incidentally, when I was put on Diltiazem, I was taken off Toprol XL and I felt so much better after Toprol was out of my system.  I had no idea it was affecting me adversely until I was off it.  I saw on the review of Toprol that for as many people who said they tolerated it well, there were an equal amount of others who had bad reactions to it."
