You should not be treated with dexamethasone if you are allergic to it, or if you have:

  • a fungal infection anywhere in your body.

Steroids can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have. Tell your doctor about any illness or infection you had within the past several weeks.

Tell your doctor if you have ever had:

  • liver disease (such as cirrhosis);
  • kidney disease;
  • a thyroid disorder;
