L56.1: Drug photoallergic response

Your skin is red after being exposed to light. The cause of this is an allergic reaction to a drug.

You have an allergic reaction to this medication. The light makes you have an allergic skin reaction. An allergy involves the immune system overreacting to certain substances in the environment. Various medications can trigger this allergic reaction. They are mainly medications that are applied to the skin. However, there may also be medications that you can take as a tablet.

When light is shone on unprotected skin, small red spots may appear. The skin can also be flat, red and swollen. The extent may depend on how strong the light was and how long it has been on the skin. Small or fairly large blisters may appear on the reddened areas. The affected skin can itch severely.
