Hello, I understand your concern. Thera flu contains an ingredient that constricts blood vessels, which would make high blood pressure worse, so it is best to avoid taking it. Coricidin is fine if you carefully follow dosing instructions. However, your safest bet is to take acetaminophen and a saline nasal spray. Also drinking plenty of fluids, getting plenty of rest and increasing the humidity in your home would be the sensible thing to do. I hope this helps. Wishing you good health and all the best.
