Clinical monograph
How it works
A synthetic glucocorticoid that suppresses inflammation and immune responses through the glucocorticoid receptor.
Prescribing in practice
- Do not stop a prolonged course abruptly — taper to avoid adrenal crisis.
- Longer use brings a wide range of effects (hyperglycaemia, hypertension, osteoporosis, peptic-ulcer risk, mood disturbance, infection including reactivation, Cushingoid features, growth effects in children).
- Consider gastroprotection, bone protection and infection precautions where appropriate.
Monitoring
Monitor glucose, blood pressure and weight; review bone health and eyes with long-term use; review mood and infection risk.
Counselling the patient
- Take it in the morning, with food; never stop a longer course suddenly.
- Carry a steroid card; report signs of infection or severe abdominal pain.
- If you are not immune, contact with chickenpox or measles needs prompt advice.
