Prednisone is a steroid used to treat inflammatory types of arthritis, such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA), ankylosing spondylitis(AS), juvenile idiopathic arthritis (JIA), acute gouty arthritis, lupus, and polymyalgia rheumatica. It is a potent and fast-acting anti-inflammatory agent, but can cause stomach upset and long-term use can cause diabetes, weight gain, high blood pressure, osteoporosis, and mood changes.
