my father inlaw is currently taking zocor,celebrex,nexium,diovan,athonol, an iron pill and a baby asprin. he typicially takes them all at the same time right before bed. his oxygen level is 90+. whenever his heart rate is elevated he suffers loss of breath and is unable to walk short distances without loosing his breath. doctors so far have been baffled by his symptoms is he taking his meds inproperly?
