Lightheadedness and slight dizziness, feeling slightly like fainting. Shortness of breath and using beclomethasone inhaler, which doesn t help. EKG in Dr. s office looked normal. Waiting for pulmonary test scheduled. Normal weight, moderately active when shortness of breath doesn t interfere, low-fat vegan diet, nonsmoker, clear lung x-ray in 2009. (Was taken for shortness of breath due to stress, whcih doctor and I think is probable now.)Blood pressure normally 112/64, was 103/52 in office recently but normal readings since then. But the lightheadedness and faintness is new, lasting all day today. Drinking more water hasn t helped yet. Could beclomethasone cause it?
