Dx early dbl pneumonia 7d ago. not taking my prednisone prescription. ok to take as-needed conservatively rather than full 11-day course?

Take as prescribed: There are usually well-established and scientifically documented reasons to take prescription medicines as prescribed. If a medicine is not prescribed to be taken "as needed", it rarely works the way it is intended to work if you take it that way. I would recommend that you take your Prednisone the way it is prescribed unless you have contacted your doctor and he/she okays the change.
