Nobody truly knows: Nobody truly knows whether or not there are good or bad effects of Zicam on blood pressure drugs, because Zicam is not an FDA approved medication. It's an over-the-counter item sold with claims of decreasing cold symptoms. Haven't heard of reports of problem interactions between the two items, but there probably aren't any good studies on the issue.
