Betamethasone is a powerful medication belonging to a class of drugs called corticosteroids. It is commonly used to reduce inflammation and suppress the immune system in various conditions, such as allergies, skin disorders, and certain types of arthritis. By mimicking the effects of hormones produced by the adrenal glands, betamethasone helps alleviate symptoms like swelling, redness, and itching. This medication can be administered in several forms, including tablets, injections, and topical creams. While effective, it is essential to use betamethasone under a doctor's guidance, as long-term use can lead to side effects like weight gain, mood changes, and increased risk of infections.
