Prednisone is a corticosteroid medication that is commonly used to treat a variety of conditions, ranging from inflammatory disorders to autoimmune diseases. It works by suppressing the immune system and reducing inflammation in the body. Prednisone can be prescribed to manage conditions such as asthma, rheumatoid arthritis, lupus, allergies, and certain types of cancer. Additionally, it may be used to prevent organ rejection after a transplant or to treat symptoms of certain skin conditions. However, prolonged use or high doses of prednisone can lead to various side effects, including weight gain, mood changes, increased blood sugar levels, and weakened immune system function. Therefore, it is important for patients to take prednisone exactly as prescribed by their healthcare provider and to closely monitor for any adverse effects.
