Prednisone is a type of corticosteroid medication that mimics a natural hormone called cortisol. It is used to treat various conditions like allergies, asthma, rheumatoid arthritis, gout, lupus, vasculitis, cancer, and multiple sclerosis symptoms. Prednisone reduces inflammation, pain, redness, and swelling by suppressing the immune system, which can sometimes overreact and attack the body’s tissues. The dosage of prednisone depends on the specific condition and its severity. High doses may be prescribed for short periods during flare-ups, while lower doses may be used for long-term maintenance. Common side effects include upset stomach, which can be minimized by taking the medication with food. Never stop taking prednisone suddenly if used for more than two weeks; instead, follow your doctor's instructions for gradually decreasing the dose to allow your body to adjust. Always consult your doctor if you have other health conditions before taking prednisone.
