Rayos is used to treat conditions such as rheumatoid arthritis, lupus, psoriasis, asthma, allergic reactions, inflammatory bowel disease, multiple sclerosis flare-ups, and certain skin conditions. It may also be prescribed for adrenal insufficiency and other disorders requiring anti-inflammatory or immunosuppressive therapy.
Rayos contains prednisone, a synthetic corticosteroid that works by binding to glucocorticoid receptors in cells, reducing the production of inflammatory substances and suppressing the activity of the immune system. This helps decrease swelling, redness, and allergic responses throughout the body.
Rayos should not be stopped abruptly after prolonged use, as this can cause adrenal insufficiency. Common side effects may include increased appetite, mood changes, weight gain, elevated blood sugar, and fluid retention. Long-term use requires monitoring by a healthcare provider for potential complications including bone loss, infections, and cataracts.
