1. About hydrocortisone
Hydrocortisone is a corticosteroid medicine or ‘steroid’.
It works by damping down the body’s immune response to reduce pain, itching and swelling.
It can also be used as hormone replacement for people who don't have enough of the natural stress hormone, cortisol.
Hydrocortisone is used to treat many health problems. The medicine comes in different ways, including skin creams for the body and scalp, injections and tablets. The type of hydrocortisone you use will depend on your health problem.
NHS coronavirus advice
As long as you have no symptoms of coronavirus infection, carry on taking your prescribed steroid medicine as usual.
If you develop any coronavirus symptoms, do not stop taking your steroid medicine suddenly. Ask your doctor about whether you need to stop taking it or not.
