by mouth, initially, up to 10–20 mg daily (severe disease, up to 60 mg daily), preferably taken in the morning after breakfast; can often be reduced within a few days but may need to be continued for several weeks or months

  • Cushing’s syndrome .

Side effects:

Steroid withdrawal syndrome may lead to : anorexia, nausea, vomiting, weight loss , headache , myalgia & hypotension.
Side effects include:
Edema, alkalosis, hypokalemia, hypertension, CHF muscle wasting , weakness, osteoporosis, nausea & vomiting.
Headache , hypercholesterolemia , hirsutism, amenorrhea, depression.
Redistribution of body fats: thin extremities and fat trunk, moon-like face, buffalo hump.
Nursing considerations:
  • Administer oral forms with food to minimize ulcerogenic effect.
  • For chronic use, give the smallest dose possible.
  • Corticosteroids should be discontinued gradually if used chronically.
  • Document baseline weight , B.P. , Pulse & temperature.
  • Frequently take BP, monitor body weight (signs of Na+ & H2O retention).
  • Periodic serum electrolytes, blood sugar monitoring.
  • Report signs & symptoms of side effects (cushing-like syndrome).
  • Discuss with female client potentials of menstrual difficulties.
  • Instruct the client to take diet high in protein & potassium.
  • Instruct the client to avoid falls & accidents (osteoporosis causes
  • pathological fracture).
  • Remind the client to carry a card identifying the drug being used.
  • Stress the need for regular medical supervision.
