Have you tried Contac? That's what my dad takes for colds and he's been on high blood pressure meds for years (he currently takes Lipitor IIRC)
No, but I remember the days when my parents did. I'll have to give that a try. Fortunately, I'm cold free and I can manage allergies pretty well without anything. I've fudged a couple of times on advil--only thing that works on my bad headaches, but supposedly that is not good with the bp either--ugh!
