Dexamethasone is a corticosteroid used to reduce inflammation and suppress an overactive immune response.
It is commonly used for:
• Inflammatory conditions: Reduces inflammation in conditions such as arthritis and certain skin disorders.
• Allergic reactions: Helps manage severe allergic reactions alongside other treatments.
• Autoimmune conditions: Used to control conditions where the immune system attacks the body's own tissues.
• Certain cancers: Used as part of treatment protocols for some blood cancers, alongside other medicines.
• Brain swelling: Helps reduce swelling associated with certain brain tumours or injuries.
• Respiratory conditions: Used to reduce airway inflammation in certain severe respiratory conditions.
Insomnia
Anxiety
Mood changes
Increased appetite
Weight gain
Dexamethasone works by mimicking the action of cortisol, a natural hormone that regulates inflammation and immune activity.
It suppresses the release of substances in the body that trigger inflammation, such as prostaglandins and certain immune signalling molecules.
By reducing this inflammatory response and dampening an overactive immune system, dexamethasone helps relieve swelling, redness, and other symptoms associated with inflammatory and autoimmune conditions.
