Photosensitivity and Its Causes, Symptoms, and Treatment

Strange susceptibility of the skin to ultraviolet light, causing redness and suffering, is called photosensitivity. Various materials may cause photosensitivity, including drugs like tetracyclines, diuretics and oral contraceptives, along with compounds used in the production of cosmetic. The rare metabolic disorder porphyria may also cause photosensitivity.

What Are The Symptoms?

The reaction happens in regions of skin often exposed to sun, like the face and hands. Not much exposure is needed. The effects typically grow soon after exposure, but may be delayed for 24-48 hours. The symptoms include:

  • reddish, frequently debilitating, rash
  • little, itchy blisters
  • scaly skin.

What Is The Treatment?

  • To alleviate symptoms, the physician may prescribe topical corticosteroids.
  • Oral antihistamines may be prescribed.
  • Serious cases are treated with restricted exposure to ultraviolet light, occasionally joined with drugs, to desensitize the skin.
  • If a specific drug is causing photosensitivity, your physician may have the ability to prescribe another drug.


It’s possible for you to help restrain the reaction by preventing sun as much as possible. When outside, cover your skin, wear a hat and use a complete sunblock.
