What causes foamy vomiting while on BP medication?
Patient: I have had a cough since December. Sometimes it makes me throw up white foam. I started taking blood pressure medicine in December. I have tried two different kinds. I stopped taking them a week ago and have not noticed any difference in my coughing. My voice is horse and I do not sleep much. No amount of cough syrup or cough drops will make it quit. I sneeze some with the coughing and my eyes will run and my nose will run. Could this just be allergies? Doctor: Hello and Welcome to ‘Ask A Doctor’ service.
