Corticosteroid medications are synthetic drugs that mimic the effects of hormones produced by the adrenal glands. They are commonly used to reduce inflammation and suppress the immune system in various conditions, such as asthma, arthritis, and allergies. These medications can be administered in different forms, including pills, injections, and topical creams. While corticosteroids can be effective in managing symptoms, they may also cause side effects, especially with long-term use. Common side effects include weight gain, mood changes, and increased risk of infections. It is important for patients to work closely with their healthcare providers to monitor and manage these potential risks.
