Prednisone is a synthetic corticosteroid medication used to treat a variety of conditions, primarily those related to inflammation and immune system disorders. It works by reducing inflammation and suppressing the immune system's response, which can help alleviate symptoms such as swelling, pain, and allergic reactions.

This medication is commonly prescribed to manage conditions such as asthma, rheumatoid arthritis, lupus, certain skin conditions, allergic reactions, and inflammatory bowel disease. It can also be used to prevent rejection of organ transplants and to treat certain types of cancer.

Prednisone is typically taken orally in the form of tablets or liquid, and the dosage and duration of treatment depend on the specific condition being treated and the individual's response to the medication. Like all medications, prednisone can cause side effects, ranging from mild to severe, and long-term use may require careful monitoring by a healthcare professional.

It's important for individuals prescribed prednisone to follow their healthcare provider's instructions carefully and to report any side effects or concerns promptly. Additionally, sudden discontinuation of prednisone can lead to withdrawal symptoms, so it's essential to taper off the medication gradually under medical supervision when stopping treatment.
