An allergic reaction occurs when we are exposed to an allergen. This is a substance that the body recognises as foreign and reacts to. It may be something we contact on our skin (such as chemicals in detergents or softeners, metallic elements in jewellery, or even grass) or it may be something that we have eaten (a food, drink or medicine).
Many allergic reactions involve a skin rash which is usually characterised by small red bumps (hives) or large welts. They are usually very itchy.
If the rash is only on a small area it is probably due to something the child was in contact with, rather than something that was consumed which generally results in a more widespread reaction involving large areas of the body.
An allergic reaction does not usually involve temperatures and whilst it is uncomfortable it does not cause the child to feel ill. Our pharmacists can advise on a suitable antihistamine medication which will help to stop an allergic reaction.
It is important to try to identify the cause of an allergic reaction so that it can be avoided in future. If you suspect that your child has an allergic reaction to a prescribed medication (such as an antibiotic) it would be important to have your doctor confirm this so that it is not prescribed again.
