The pericardial effusion which has now been reported even on the low dose of 1.25 mgs which I prescribe often, creates warnings with swelling of the feet, legs, face and other body parts.  When fluid builds up inside of the pericardial cavity (the sac around the heart), the heart has difficulty with blood return and thereby goes into heart failure over a period of time.  Systemic swelling should be the warning everyone should recognize, and then stop the drug and contact their doctor.
