Corticosteroid, which was first used in 1948, is often used as an anti-inflammatory medication and immune suppressant to treat arthritis, asthma, autoimmune diseases (including lupus and multiple sclerosis), skin conditions (such as eczema and psoriasis), some types of cancer (such as leukemia), and the aftermath of organ transplant. As a matter of fact, this drug mimics cortisol, which is a hormone that's naturally produced by the adrenal glands in healthy people. Although corticosteroid is an effective medication, it can also have serious side effects such as glaucoma, fluid retention, high blood pressure and weight gain. There can even be psychological effects, including mood swings, confusion and behavior changes. Taking the medication long term can also lead to cataracts, high blood sugar and diabetes, increased risk of infection from common bacteria and viruses, osteoporosis, suppressed adrenal-gland hormone production, and thin skin that has higher rates of bruising and slower wound healing. So, in order for you to be safe, take Corticosteroid exactly as prescribed. In addition, make sure you take this medication after a meal as it may cause nausea if you take it on an empty stomach. It is worth noting that Corticosteroids have a low but significant teratogenic effect, causing a few birth defects per 1,000 pregnant women treated. Corticosteroids are therefore contraindicated in pregnancy
