What is dexamethasone?
Dexamethasone is a steroid that prevents the release of substances in the body that cause inflammation.
Dexamethasone is used to treat many different conditions such as allergic disorders, skin conditions, ulcerative colitis, arthritis, lupus, psoriasis, breathing disorders, inflammatory eye conditions, blood cell disorders, leukemia, or endocrine disorders.
Dexamethasone may also be used for purposes not listed in this medication guide.
You should not use this medication if you have a fungal infection anywhere in your body.
Before taking this medicine
You should not use this medication if you are allergic to dexamethasone or sulfites, or if you have a fungal infection anywhere in your body.
Steroid medication can weaken your immune system, making it easier for you to get an infection. Steroids can also worsen an infection you already have, or reactivate an infection you recently had. Before using this medication, tell your doctor about any illness or infection you have had within the past several weeks.
To make sure dexamethasone is safe for you, tell your doctor if you have:
a thyroid disorder;
a history of malaria;
a muscle disorder such as myasthenia gravis;
glaucoma or cataracts;
herpes infection of the eyes;
depression or mental illness;

Your dosage needs 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.
This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using dexamethasone.
After your treatment ends, you may have withdrawal symptoms such as fever, weakness, and joint or muscle pain. You should not stop using dexamethasone suddenly.
What happens if I miss a dose?

What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
