Can you tell me about it's like to use a hydrocortisone pill, spray or lotion for allergies?

Hydrocortisone: Hydrocortisone is a steroid which is available over the counter in topical preparations like creams, ointments, and sprays. For rashes and hives, these topical preparations are fairly effective in helping the itch. Oral hydrocortisone is not available OTC and needs to be prescribed by a health care provider. It is not a first choice for allergies - try an oral antihistamine first.
