Light sensitivity or photosensitivity refers to a notable or increased reactivity to light. Apart from vision, human beings have many physiological and psychological responses to light. In rare individuals an atypical response may result in serious discomfort, disease, or injury. Some drugs have a photosensitizing effect.
Rare (<0.1%) adverse effects include: Urinary retention; Prolonged QT interval; Torsades de Pointes; Ataxia; Breast enlargement or engorgement; Lactation; Cardiospasm
Many synthetic compounds, including drug substances like tetracyclines or fluoroquinolones, are known to cause these effects. Surface contact with some such chemicals causes photodermatitis, and many plants cause phytophotodermatitis. Light-induced toxicity is a common phenomenon in humans; however, it also occurs in other animals.
Cause skin photosensitivity, [19] so exposure to the sun or intense light is not recommended; Cause drug-induced lupus, and hepatitis; Cause microvesicular fatty liver [20] Cause tinnitus [21] [22] Cause epigastric pain [19] Interfere with methotrexate by displacing it from the various protein-binding sites
Pain treatment with long-acting opioids, such as morphine, is often indicated, and, in cases where seizure or neuropathy is present, gabapentin is known to improve outcome. [42] Seizures often accompany this disease. Most seizure medications exacerbate this condition. Treatment can be problematic: barbiturates especially must be
Acute photosensitivity reaction in EPP. EPP usually presents in childhood with the most common mode of presentation as acute photosensitivity of the skin. It affects areas exposed to the sun and tends to be intractable. A few minutes of exposure to the sun induces pruritus, erythema, swelling and pain. [4]
