Dexamethasone

What is Dexamethasone?

Dexamethasone is a powerful corticosteroid medicine used to reduce inflammation, swelling, and immune reactions in the body. Doctors prescribe it for many conditions, including allergies, asthma flare-ups, arthritis, skin problems, and certain hormonal and autoimmune disorders. It is available as a tablet, injection, eye drop, and oral solution, making it suitable for short-term or long-term treatment. Dexamethasone is widely used worldwide because of its strong anti-inflammatory and immune-modulating effects.

• Skin disorders and rashes

• Eye inflammation

• Brain swelling

• Certain cancers (as part of chemotherapy support)

Dexamethasone mechanism

Dexamethasone works by suppressing the immune system’s inflammatory response. It blocks the release of substances that cause swelling, redness, and allergic reactions. This action helps calm the body’s immune activity and provides relief from many inflammatory and autoimmune conditions.
