What does it do?

Hydrocortisone belongs to a class of steroid hormones naturally produced by the adrenal cortex. It is primarily used to reduce inflammation and modulate immune responses. It is used in the treatment of skin disorders, allergies, and hormonal deficiencies.

Hydrocortisone reduces swelling and itching by inhibiting the production of substances in the body that cause inflammation. It also modulates the activity of immune cells, alleviating excessive immune responses. As a result, symptoms of inflammation and allergy are improved.
