Vasodilators work to relax the muscles in the walls of the blood vessels, which helps the vessels widen.
Some commonly prescribed vasodilators include hydralazine hydrochloride (Apresoline) and minoxidil (Loniten).
More serious potential side effects of vasodilators include difficulty breathing; swelling in your face, throat, lips, tongue, feet or hands; and joint pain. Less serious side effects include nausea, vomiting, diarrhea, headache and anxiety.
