L56: Other acute skin changes due to ultraviolet radiation
L56.0: Drug phototoxic response
Various medications can cause the skin to react more sensitively to sunlight or artificial light than it would do normally. These medications can include medications that are applied to the skin. 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. The red patches can appear immediately or hours to days later. Small or fairly large blisters may appear on the reddened areas. The affected skin can be very sore or remain darker after the redness has faded.
