Erythema multiforme

Erythema multiforme is a skin rash(usually mild) that's caused by an allergic reaction to the herpes simplex virus .

The spots look like targets, with a dark red centre and paler ring around the outside. The hands or feet tend to be affected first, followed by the limbs, upper body and face.

Your child will probably feel unwell and may have a fever, which you should be able to treat with over-the-counter medicine. It may takefrom twoto six weeks before they feel better.See your GP if your child has a rash and seems unwell.

In rare cases, erythema multiforme can be triggered by a reaction to certain medications, such as an antibiotic or anticonvulsant. This more severe form is called Stevens-Johnson syndrome and it can belife-threatening.
