Relieving skin redness, swelling, itching and pain associated with allergic skin reactions such as:
- Insect bites or stings.
- Nettle rash (urticaria or hives).
The cream may be used on adults and children aged six years and over.Histergan cream contains the active ingredient diphenhydramine hydrochloride, which is a type of medicine called an antihistamine.
Diphenhydramine works by preventing the actions of histamine – a compound produced by the body when it reacts to a foreign substance, such as saliva or venom from insect bites or stings (these are known as allergens).
Histamine causes a chain reaction that results in inflammation (redness, swelling and itching) of the skin. Diphenhydramine blocks histamine receptors and so stops this chain reaction in the skin.
The cream is most effective when applied as soon as possible after getting the bite or sting.
