Many medications and conditions can cause sun sensitivity, including:

* [[Psoralen]]s, [[coal tar]]s, photo-active dyes ([[eosin]], [[acridine orange]])
* [[Musk ambrette]], [[methylcoumarin]], [[lemon oil]] (may be present in fragrances)
* [[4-Aminobenzoic acid|PABA]] (found in sunscreens)
* [[Oxybenzone]] (UVA and UVB chemical blocker also in sunscreens) <ref>Rodriguez E, Valbuena MC, Rey M, Porras de Quintana L. 2006. Causal agents of photoallergic contact dermatitis diagnosed in the national institute of dermatology of Colombia. Photodermatol Photoimmunol Photomed 22(4): 189-192.</ref>

Photodermatitis can also be caused by plants such as ''[[Ammi majus]]'', [[parsnip]], giant hogweed (''[[Heracleum mantegazzianum]]''), common rue (''[[Ruta graveolens]]''), and ''[[Dictamnus]]'', a [[genus]] of [[angiosperms|flowering plants]] in the family [[Rutaceae]] with a single species ''Dictamnus albus'', commonly called the burning bush. Photodermatitis caused by plants is called [[phytophotodermatitis]].
