1. What Dexamethasone is and what it is used for

The name of your medicine is Dexamethasone. This belongs to a group of medicines called corticosteroids.

Corticosteroids are hormones that are found naturally in your body that help to keep you healthy and well. Boosting your body with extra corticosteroid, such as Dexamethasone, is an effective way to treat various illnesses involving inflammation in the body. Dexamethasone lowers inflammation, which could otherwise go on making your condition worse. You must take this medicine regularly to get maximum benefit from it.

Dexamethasone can be used to:

  • Reduce inflammation
  • Treat a number of different diseases of the immune system

2. What you need to know before you take Dexamethasone

Do not take Dexamethasone:

  • If you are allergic to dexamethasone or any of the other ingredients of this medicine (listed in section 6). The signs of an allergic reaction include a rash, itching or shortness of breath
  • If you have an infection that affects the whole body
  • If you need to have a vaccination, particularly with ‘live virus’ vaccines

Do not take this medicine if any of the above apply to you.
