Sun Allergy Disease

Spending time in the sun is usually a pleasurable experience that leaves us with happy memories of enjoying the outdoors. But for those with a sun allergy, even a few moments in the sun can cause a painful reaction.

  1. Sun allergy disease

    • Sun allergy disease is the immune system's response to sun exposure in sun-sensitive people. The resulting allergic reaction can produce a rash that may contain blisters or hives.

    Causes

    • A sun allergy can be inherited genetically. Other causes may be photosensitivity caused by cosmetics or medications that have been applied to the skin, or oral medications such as NSAIDs, some antibiotics, diuretics, antidepressants and contraceptives.

    Treatment

    • A mild reaction to the sun may require an oral or topical antihistamine to relieve itching. With severe or persistent symptoms, your doctor might prescribe a stronger antihistamine or corticosteroid. A very severe sun allergy may require phototherapy treatment or antimalarial drugs.

    Prognosis

    • The prognosis for sun allergy is good, although in some cases it may take several years to be fully cured.

    Prevention/Solution

    • Use a broad-spectrum sunscreen with an SPF 15 or higher when outdoors. Wear long sleeved shirts, long pants, a hat and sunglasses. If you are taking medications that may cause a sun reaction, talk with your doctor about precautions you should take.
