Approved for medical use in 1961, Dexamethasone is used to treat many conditions such as rheumatic problems, a number of skin diseases, severe allergies, asthma, chronic obstructive lung disease, croup, brain swelling, and along with antibiotics in tuberculosis. In preterm labor, this medication may also be used to improve outcomes in the baby. It is worth noting that Dexamethasone reduces inflammation by stopping cells from releasing chemicals that normally help produce immune and allergic responses. To ensure the effectiveness of this treatment, you should take it at the time(s) recommended by your doctor. Plus, you need to take Dexamethasone with food so as to reduce stomach upset from the drug. Bear in mind that the long-term use of Dexamethasone may result in thrush, bone loss, cataracts, easy bruising, or muscle weakness. Besides, its use during pregnancy should be based on benefits being predicted to be greater than risks. However, Dexamethasone should NOT be taken by nursing mothers.
