Corticosteroids are used to reduce inflammation in lupus by suppressing the immune system. They are effective in relieving pain, rashes, and swelling but can have serious side effects, especially with high doses or long-term use. Side effects include weight gain, osteoporosis, high blood pressure, diabetes, and an increased risk of infections. To manage these side effects, it's important not to smoke, maintain a healthy diet, exercise regularly, and follow your doctor's advice on medication dosage. Your doctor may also prescribe additional medications to counteract some side effects, such as calcium and vitamin D supplements for bone health.
