DEXAMETHASONE

Dexamethasone is an anti-inflammatory medication classified under the corticosteroid drug class. The U.S. FDA initially approved dexamethasone for medical use in 1958.

It is used to relieve inflammation (swelling, heat, redness, and pain) in various diseases of multiple organs, including serious illnesses such as severe allergic reactions, shock caused by infection or tuberculosis, skin disorders, endocrine disorders, gastrointestinal diseases, blood disorders, nervous and renal diseases, eye conditions, and rheumatic disorders. It is also used to treat certain types of cancer. It was also used as a treatment for COVID-19 in adult and adolescent patients. It acts by reducing inflammation and suppressing the immune system.

Dexamethasone is available as an oral tablet and solution for injection. It is a prescription medicine. Your doctor will decide the dose and frequency of the medicine. Take dexamethasone as prescribed by your doctor. Take this tablet by mouth. Swallow the tablets whole with water. Do not break, chew, or crush the tablets. Take the tablet with food to avoid stomach upset. The injection will be given to you by your doctor or nurse. Dexamethasone injection is administered intravenously (into your vein) or intramuscularly (into your muscle), depending on your disease condition. It can sometimes also be given by injection under the skin (subcutaneously) to relieve certain symptoms, including pain, tiredness, weight loss, and feeling and being sick.
