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 use Dexamethasone

Do not use 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 have an infection of a joint
  • if you have unstable joints. This is a condition where joints, such as the knee, can suddenly give way.
  • Do not have this medicine if any of the above apply to you.

Warnings and precautions

Talk to your doctor or pharmacist before using Dexamethasone:

  • If you have ever had severe depression or manic depression (bipolar disorder). This includes having had depression before while taking steroid medicines like Dexamethasone
  • If any of your close family has had these illnesses

If either of these applies to you, talk to a doctor before having this medicine.

Mental health problems can happen while having steroids like Dexamethasone (see also section 4).

  • These illnesses can be serious
  • Usually they start within a few days or weeks of starting the medicine
  • They are more likely to happen at high doses
  • Most of these problems go away if the dose is lowered or the medicine is stopped. However, if problems do happen, they might need treatment

Talk to a doctor if you (or someone taking this medicine), show any signs of mental problems. This is particularly important if you are depressed, or might be thinking about suicide. In a few cases, mental problems have happened when doses are being lowered or stopped.
