[|Human|] Hi. The last two mornings I wake up and feel dizzy. When I stand to walk I drift to the right. It is not vertigo, it is lightheadedness. It takes a few hours to go away. When I turn my head right to left I can feel it linger. Have not checked orthostatic b/p yet, however, it seems to last too long after remaining upright to be a b/p problem. Started a Z pack yesterday at 3:00 p.m. No real sinus infection symptoms. I do have COPD. Any ideas?
[|AI|]  Hello, Actually, if you were truly orthostatic your condition would likely get WORSE as you continued to stand and walk not better.  However, it is possible that you are NOT orthostatic but have another problem which could be what is referred to as VERTEBROBASILAR INSUFFICIENCY which is a transient loss of blood to a portion of the brain stem and cerebellum that involves the function of balance and gait steadiness which explains the veering and feelings of dizziness.  Z-packs are felt to be overused these days for simple infections and are recommended not to be prescribed for simple infections.  If you've no real sign of infection then, even less reason to use the antibiotic.  I would definitely recommend getting your blood pressures checked for orthostatic Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further. Take care
