Hi. Since it's the weekend i can't get a hold of my doctor to ask this question, though i will this week. I take Toprol for my heart, and i have really bad PACs, so i was suggested to take the Hawthorn. Obviously on the internet it says you should ask your doctor before taking the two together, as Toprol slows your heart, and supposedly Hawthorn does the opposite? Anyways, i am not taking the Hawthorn yet, just wanted to see if there were any ppl out there who takes the two together, and if it messed with them. Like i said, i know what i've read about not mixing the two before you ask the doctor, just was wanting feedback from those that do or have. Thanks!
