Defacort is a steroid
and decreasing its dose will not lead to a swelling in the whole body. Swelling in the body can be due to a problem in the heart, liver
or kidneys. We can only know what is causing the problem by doing the following tests:
a. Kidney function test- blood urea and serum creatinine
b. Urine 24 hour protein
c. Liver function tests
