Can Vitamin D affect heart rate if taken with other drugs?
Can Vitamin D have an adverse effect on heart rate (slow it, cause dizziness) when taken with Lopressor, Flecainide, and or coumiden? As soon as I stopped taking Vitamin D the high heart rate and dizzy feeling stopped.
Vitamin D has been reported to interfere with the absorption and effects of some heart medications. There is very little data available on vitamin D interactions with the medications you listed but you must remember everyone responds differently to medications. You did the right thing by stopping the vitamin D and it sounds like you may have been experiencing a drug interaction you should discuss this further with your healthcare provider. We always recommend before starting,stopping or adjusting any medication whether it be a prescription medication or over-the-counter medication/supplement that you have a discussion with your healthcare provider and pharmacist.
