Dexamethasone, a corticosteroid, is similar to a natural hormone produced by your adrenal glands. It often is used to replace this chemical when your body does not make enough of it.
What is dexamethasone?
Dexamethasone is a corticosteroid that prevents the release of substances in the body that cause inflammation.
Dexamethasone is used to treat many different inflammatory conditions such as allergic disorders, skin conditions, ulcerative colitis, arthritis, lupus, psoriasis, or breathing disorders.
Dexamethasone may also be used for purposes not listed in this medication guide.
You should not use this medication if you are allergic to dexamethasone, or if you have a fungal infection anywhere in your body.
Before taking dexamethasone, tell your doctor about all of your medical conditions, and about all other medicines you are using. There are many other diseases that can be affected by steroid use, and many other medicines that can interact with steroids.
Your dexamethasone dosage may change if you have any unusual stress such as a serious illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any such situation that affects you during treatment.
Dexamethasone can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.
Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medication.
Do not receive a "live" vaccine while you are taking dexamethasone. Vaccines may not work as well while you are taking a steroid.
Do not stop using dexamethasone suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.
Wear a medical alert tag or carry an ID card stating that you take dexamethasone. Any medical care provider who treats you should know that you are using a steroid.
