Sun Allergy Symptoms
Sun allergies, also known as photosensitivity or photosensitivity reactions, are caused by an abnormal response of the immune system to the sun’s ultraviolet (UV) rays. Symptoms of a sun allergy can range from mild to severe and may include redness, itching, hives, and blisters. In severe cases, the reaction may be life-threatening.
Causes of Sun Allergy
Sun allergies can be caused by medications, chemicals, plants, or other substances. Common medications that can cause sun allergies include nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen, antibiotics such as tetracycline, and diuretics. Certain plants, such as poison ivy, can also cause sun allergies.
Diagnosis and Treatment
Diagnosis of a sun allergy typically involves a physical examination and a review of the patient’s medical history. Treatment may involve avoiding exposure to the sun, using sunscreen, or taking antihistamines or topical corticosteroids. In some cases, immunosuppressive drugs may be prescribed to reduce the body’s reaction to the sun.
